Description

Information reporting method, base station and core network equipment

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to an information reporting method, a base station, and a core network device.

Background

With the development of communication technology, a Dual Connectivity (DC) architecture is introduced into a New Radio system (New Radio, NR), that is, a User Equipment (UE) is accessed to a core network device (e.g., Mobility Management Entity (MME)) through two base stations. One of the two base stations (with the same or different standards) serves as a main base station, the other base station serves as an auxiliary base station, and under a DC architecture, signaling connection generally exists between the main base station and core network equipment.

For the DC architecture, one UE transmits data through two base stations of different systems (for example, the main base station is a fourth generation (4G) base station), and the auxiliary base station is a 5G base station), and the charging policies usually corresponding to the base stations of different systems may be different, so that the base stations are required to report statistical information, so that the core network device can distinguish the statistical information of the base stations of different systems, and configure corresponding charging policies for the base stations of different systems according to the statistical information of the base stations of different systems.

In a conventional technical solution, as shown in fig. 1, a core network device usually reports a Charging Data Record (CDR) periodically (e.g., CDR1 corresponding to a first T period in fig. 1), and after a current period elapses, the core network device closes a Charging Data Record (e.g., CDR1) corresponding to the current period, and opens a new Charging Data Record (e.g., CDR2) in a next period. In addition, the base station usually reports the statistical information to the core network device (e.g., T2 and T3 shown in fig. 1).

However, in the conventional technical solution, the base station reports the statistical information to the core network device only when an event trigger condition is met (for example, when a handover procedure is executed, a procedure involving a change of the base station is performed, or the UE enters an Idle state (Idle) to disconnect a data connection between the base station and the user plane functional network element), so that a period for reporting the statistical information by the base station is very irregular, and the core network device generally adopts a periodic statistical report (for example, a period T1 shown in fig. 1 is a period), as shown in fig. 2, so that the statistical information reported by the base station is inconsistent with the period for reporting the CDR by the core network device after reaching the core network device, and finally, the charging system is likely to receive the statistical information reported by the base station when processing the CDR 3.

Disclosure of Invention

Embodiments of the present application provide an information reporting method, a base station, and a core network device, so as to solve a problem in the prior art that periods of statistical information reported by the base station and the core network device are inconsistent.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, the present application provides a method for reporting information, including: the first base station sends a double connection instruction to the core network equipment; a first base station receives a first instruction sent by core network equipment; the first base station determines a first period according to the first indication, wherein the first period is the same as a second period of the second statistical information reported by the core network equipment; the first base station reports first statistical information to core network equipment, wherein the first statistical information is obtained according to a first period.

The application provides a method for reporting information, which sends a dual-connection indication to a core network device through a first base station to trigger the core network device to send a first indication to the first base station, so that the first base station can determine a first period for reporting first statistical information, in a dual-connection scenario, when the first base station is a master base station, in a scenario in which the master base station counts and reports the first statistical information, the first base station can determine a first period through the first indication, and report the first statistical information to the core network device periodically according to the first period, on the other hand, because the first period is the same as the second period, the first statistical information reported by the first base station in the first period is consistent with second statistical information reported by the core network device in the second period, on the other hand, in a scenario in which a secondary base station counts the first statistical information, the first period can be sent to the auxiliary base station through the first base station, the auxiliary base station counts the first statistical information according to the first period, and the first statistical information is reported to the core network equipment through the first base station, so that the first statistical information reported to the core network equipment by the first base station is consistent with the second period of the second statistical information reported by the core network equipment.

With reference to the first aspect, in a first possible implementation manner of the first aspect, if the first statistical information is obtained by the first base station according to the first period, the reporting, by the first base station, the first statistical information to the core network device includes: the first base station reports the first statistical information to the core network equipment according to the first period.

With reference to the first aspect or the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the determining, by the first base station, the first period according to the first indication includes: the first base station determines the second period as the first period according to the first indication; the first base station reports the first statistical information to the core network device according to the first cycle, including: and under the triggering of the first indication, the first base station reports the first statistical information to the core network equipment according to the first period. In this case, when the first base station has a second period configured in advance therein or when the first indication has the second period therein, the first base station may determine the second period as the first period upon triggering of the first indication.

With reference to any one of the first aspect to the second possible implementation manner of the first aspect, in a third possible implementation manner of the first aspect, the determining, by the first base station, the first period according to the first indication includes: the first indication comprises a first time parameter, and the first base station determines a second period configured in advance as the first period; the first indication includes a first time parameter and information indicating a second period, and the first base station determines the second period as the first period according to the information indicating the second period. In this case, in an aspect, when the first base station has a second periodicity configured in advance therein, the first base station may determine the second periodicity as the first periodicity upon triggering of the first indication. On the other hand, the first base station may determine the second period as the first period according to information indicating the second period. When the core network device determines that the first base station has the preconfigured second period, the first indication may carry the first time parameter, which may reduce signaling overhead, and on the other hand, the first indication includes both the first time parameter and information for indicating the second period, and at this time, the first base station may determine both the third period and the first period regardless of whether the first base station has the preconfigured second period.

As shown in fig. 3, fig. 3 shows a schematic diagram of a communication architecture provided in the present application, including: one or more terminal devices 101 (only one UE is taken as an example in fig. 3), a Master base station (Master RAN)102, a Secondary RAN (SRAN) 103 connected to the Master base station 102, and a core Network connected to the Master base station 102.

Specifically, in the 4G network, the core network includes: the statistical information is obtained and reported to a network element (e.g., Serving Gateway (SGW) 104), a Packet data network Gateway (PGW) 105, a mobility management network element 106, and a charging system 107 of the charging system. The Mobility Management network element 106 in the 4G network may be a Mobility Management Entity (MME).

The main base station 102 refers to a first base station that the terminal device 101 randomly accesses, that is, before the terminal device 101 changes from a single connection state to a Dual Connection (DC) state, a base station serving (Service) the terminal device 101 serves as a main base station, the main base station 102 is responsible for establishing a control plane connection with a core network (e.g., an MME or an AMF entity), transmitting a signaling message, determining whether a secondary base station is needed, and selecting the secondary base station for the terminal device 101, in addition, in the architecture shown in fig. 3, a data plane (also referred to as a user plane) connection also exists between the main base station 102 and an SGW104 of the core network, it can be understood that fig. 3 is a 4G network architecture as an example, and a data plane connection also exists between the main base station 102 and an UPF entity in a 5G network.

The secondary base station 103, a second base station outside the primary base station 102, a node for providing additional radio resources for the UE, and the core network may not have a direct control plane connection. However, the secondary base station may perform data plane communication between the primary base station and the core network (as shown in fig. 3 and 5), and the secondary base station may also establish a data plane connection with a network element (e.g., SGW) in the core network (as shown in fig. 4 and 6).

The mobility management element 106, the main base station and the SGW104 both have control plane connections, and may not have data plane connections.

The SGW104 is used as a network element for accounting the charging information, and reports the accounting information to the charging system 107 according to a preset period or event trigger. In addition, the SGW may obtain the usage information of the terminal device as the third statistical information. The usage information includes statistics obtained by the SGW itself, and may further include PGW statistics and be sent to the SGW.

The PGW105 is configured to count the statistical information of the terminal device 101, send the counted statistical information of the terminal device 101 to the SGW104, and report the statistical information to the charging system 107 by the SGW 104.

Among other things, the SGW104 and PGW105 may support control plane and user plane separation. The SGW may be divided into a service gateway Control Plane (SGW-Control Plane, SGW-C) and a service gateway User Plane (SGW-User Plane, SGW-U); the PGW may be divided into a packet data gateway Control Plane (PGW-Control Plane, PGW-C) and a packet data network user Plane (PGW-UserPlane, PGW-U).

The SGW-C is used for summarizing the first statistical information reported by the base station side and the third statistical information counted by the SGW-U. And the SGW-U is used for counting the statistical information of the terminal equipment and reporting the counted statistical information to the SGW-C as third statistical information, and the SGW-C is used for processing the first statistical information and the third statistical information and then reporting the processed statistical information to the charging system 107 as second statistical information.

The PGW-C is used for controlling data forwarding of the PGW-U, receiving the statistical information of the PGW-U and sending the statistical information to the SGW-C, the statistical information of the PGW-U can be used as third statistical information, is finally sent to the SGW-C through the PGW-C, and is used as second statistical information after being processed with the first statistical information.

The PGW-U is used for processing the data message, including receiving and sending the data message, counting the statistical information and reporting to the PGW-C. It can be understood that, in the actual deployment process, the PGW-C and the SGW-C may be deployed independently or integrated; the PGW-U and the SGW-U can be respectively and independently deployed or can be integrated into a whole.

In a 5G network, a core network includes: a mobility management network element 106, a Session Management Function (SMF) entity, a User Plane Function (UPF) entity, and a mobility management network element 106. The mobility Management element 106 may be an Access and mobility Management Function (AMF).

It should be noted that the SMF entity in the 5G network corresponds to the SGW-C and the PGW-C in the 4G network, and the UPF entity corresponds to the SGW-U and the PGW-U in the 4G network.

The primary Base Station 102 and the secondary Base Station 103 in this application may be Base stations capable of communicating with the terminal device 101, and may be Access Points (AP) in a Wireless Local Area Network (WLAN), Base stations (BTS) in a Global system for Mobile communications (GSM) or Code Division Multiple Access (CDMA), Base stations (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), evolved Node Base stations (B, eNB, or eNodeB) in LTE, or relay stations or Access points, or Network devices in a vehicle, a wearable device, and a Base Station (NB) in a future 5G Network or a Network in a future evolved Public Land Mobile Network (PLMN), and the like.

A terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. The terminal Device may communicate with one or more core network devices (e.g., network slices) via a Radio Access Network (RAN) and may also communicate with another terminal Device, such as a Device-to-Device (D2D) or Machine-to-Machine (M2M) scenario. The terminal device may be a Station (STA) in a Wireless Local Area Network (WLAN), and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a next-Generation communication system, for example, a terminal device in a fifth-Generation (5G) communication Network or a terminal device in a future-evolution Public Land Mobile Network (PLMN) Network, and the like.

As an example, in the embodiment of the present invention, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

Specifically, in the present application, the primary base station and the secondary base station are base stations of different systems. For example, the primary base station in the present application may be an Evolved Node B (eNB) in an LTE scheme, that is, a 4G base station, and the secondary base station in the present application may be a base station (gNB) in a 5G New Radio (NR) scheme, that is, a 5G base station. For a base station upgraded from 4G to 5G, such as an Evolved LTE (Evolved LTE) Evolved node b eNB, the base station may be used as a 4G base station or a 5G base station. Of course, the present application is equally applicable to other scenarios, such as: the main base station is a 5G base station, and the auxiliary base stations are all 4G base stations; or the main base station is a 2G base station, and the auxiliary base station is a 3G base station; or the main base station is a 3GPP protocol base station, and the auxiliary base station is a non-3 GPP protocol base station; or, the main base station is a non-3 GPP protocol base station, and the auxiliary base station is a 3GPP protocol base station, etc.

As shown in fig. 4, fig. 4 illustrates another communication system architecture diagram provided by the embodiment of the present invention, and the communication system architecture diagram shown in fig. 4 differs from the communication system architecture diagram shown in fig. 3 in that: in fig. 3 there is a control plane connection between the primary base station 102 and the mobility management network element 106 of the core network, and a data plane connection between the user plane entities of the core network, while in fig. 4 there is a control plane connection between the secondary base station and the user plane entities of the core network (e.g. SGW of 4G network, SGW-U of 4.5G network, UPF entities of 5G network), and both the primary base station and the secondary base station and the user plane entities of the core network (e.g. SGW).

Since the SGW and the PGW may support separation of the control plane and the user plane, the communication system architecture shown in fig. 3 in the present application may also adopt an architecture shown in fig. 5, and the communication system architecture shown in fig. 4 may also adopt an architecture shown in fig. 6.

The communication systems shown in fig. 3 to fig. 6 may be applied to a fifth generation (5G) network and other networks, which is not limited in this embodiment. If the communication system shown in fig. 3 to fig. 6 is applied to a 5G network, as shown in fig. 7, a unit or an entity corresponding to the Mobility Management element 106 may be an Access and Mobility Management function (AMF) for managing a Mobility context of a user. The first base station may correspond to a first Access Network (AN) device shown in fig. 7, and the second base station may be a second AN device; the corresponding units or entities of the SGW104 and the PGW105 may be User Plane Function (UPF) entities. The terminal equipment communicates with the AMF entity through AN N1 interface, the first AN equipment and the second AN equipment communicate with the UPF entity through AN N3 interface respectively, and the first AN equipment communicates with the AMF entity through AN N2 interface.

In addition, as shown in fig. 7, the 5G network may further include a Session Management Function (SMF) entity, a Unified Data Management (UDM) entity, an authentication server Function (AUSF) entity, an Application Function (AF) entity, a Policy Control Function (PCF) entity, and the like, which is not specifically limited in this embodiment of the present Application.

The SMF entity is responsible for a session management function, and may be configured in multiple numbers. The AMF entity communicates with the AUSF entity through an N12 interface (N12 for short); the AMF entity communicates with the UDM entity through an N8 interface (N8 for short); the AMF entity communicates with the SMF entity through an N11 interface (N11 for short); the AMF entity communicates with the PCF entity through an N15 interface (N15 for short); the AUSF entity communicates with the UDM entity through an N13 interface (N13 for short); the SMF entity communicates with the first UPF entity and the second UPF entity over an N4 interface (abbreviated N4).

The AMF entity and the SMF entity are two main nodes of a 5G control plane, and the UDM entity, the AUSF entity and the PCF entity which are matched with the AMF entity and the SMF entity execute user data management, authentication, policy control and the like.

It should be noted that the interface name between each network element in fig. 7 is only an example, and the interface name may be other names in a specific implementation, which is not specifically limited in this embodiment of the present application.

It should be noted that the first AN device, the second AN device, the AMF entity, the SMF entity, the AUSF entity, the UDM entity, the first UPF entity, the second UPF entity, the PCF entity, and the like in fig. 7 are only names, and the names do not limit the devices themselves. In the 5G network and other networks in the future, the network elements or entities corresponding to the first AN device, the second AN device, the AMF entity, the SMF entity, the AUSF entity, the UDM entity, the UPF entity, and the PCF entity may also be other names, which is not specifically limited in this embodiment of the present application. For example, the UDM entity may also be replaced by a Home Subscriber Server (HSS) or a User Subscription Database (USD) or a database entity, and the like, which are described herein in a unified manner and will not be described in detail below.

In the following embodiments, a 4G architecture is taken as an example, and a 5G architecture may also support separation of a user plane and a control plane, so that a specific architecture may refer to processing of the 4G architecture in which the user plane and the control plane are separated in fig. 5 and fig. 6, an AMF entity corresponds to an MME entity, signaling connection between a base station and a core network is completed, and statistical information of the base station may be sent to the SMF entity through the AMF entity; the SMF entity corresponds to the SGW-C, can receive the statistical information of the base station (through AMF) and the statistical information reported by the UPF entity, and send to the charging system directly or after processing; the UPF entity corresponds to the SGW-U, receives and sends data, and counts statistical information according to a certain strategy (such as periodic statistics), and can periodically count and report to the SMF entity.

The first period in this embodiment is a period in which the base station reports the first statistical information to the core network device.

The first statistical information may be statistical information of the primary base station and/or statistical information of the secondary base station. The statistical information may include one or more usage information, such as session, traffic, duration, etc.

It can be understood that the core network device in this application may be a network element having a function of acquiring charging information (e.g., the second statistical information and the third statistical information) and reporting the charging information to the charging system, for example, an SGW in a 4G network, an SGW-C in an SGW-C network, or an SMF in a 5G network, which is described below as an example, and it can be understood that the core network device may also be a network element having a related function in other networks.

The second period in this embodiment is a period in which the core network device (e.g., SGW) reports the second statistical information to the charging system 107, and may also be a period in which the core network device obtains the third statistical information.

For example, the second statistical information reported by the core network device in the embodiment of the present invention may be: second statistical information, which is sent by the SGW104 to the Charging system 107, may be called Charging Data Record (CDR), and the second statistical information may be sent to the Charging system 107 after the SGW104 processes the first statistical information and the third statistical information (for example, integrates the first statistical information counted according to the first cycle and the third statistical information counted according to the second cycle in the same time period), or may be third statistical information acquired by the SGW104 and not processed, and whether the second statistical information is processed information or not, a reporting period of the second statistical information is consistent with a reporting period of the first statistical information in time, that is, a first time of reporting the second statistical information by the core network device in any period is the same as a second time of reporting the first statistical information by the first base station to the core network device, or after the core network device reports the second statistical information at the first time, the deadline of the second statistical information in a second period is the same as the deadline of the first statistical information in a first period corresponding to the second period, or the duration of the second statistical information starting from the reporting time in the second period is the same as the duration of the first statistical information starting from the reporting time in the first period.

Before reporting the third statistical information to the charging system 107, the SGW entity, the SGW-C entity, and the SMF entity may perform processing, for example, it may be simply understood that the first statistical information and the third statistical information are referred to as second statistical information after being processed, or the first statistical information and the third statistical information may be combined according to a reporting period of the second statistical information. Integration may also be performed according to some strategy. For example, the first statistical information and the third statistical information may be integrated according to the same measurement key (measurement key) or charging key (charging key), etc., to generate the second statistical information. In addition, the second statistical information finally reported to the charging system by the core network device may not only be the original statistical information such as flow, duration, etc., but also information processed according to the charging policy. For example, according to the service-merged charge information, such as < voice, charge >, more finely < local call, charge > and < roaming call, charge >; < internet, cost > and more specifically, < intra-provincial traffic, cost >, < national traffic, cost >, etc.

Based on the communication systems shown in fig. 3 to fig. 6, as shown in fig. 9, fig. 9 is a schematic flow chart of a method for reporting information provided by the present application, including:

s101, the first base station sends a double connection instruction to the core network equipment.

All descriptions herein are in terms of "dual connectivity," and indeed, multiple connectivity is possible. The system of the auxiliary base station and the system of the main base station can be executed according to the scheme of the application.

Optionally, the first base station in this application is a master base station in the architectures shown in fig. 3 to fig. 7.

As a possible implementation manner, the first base station may carry the dual connectivity instruction in a first message, and send the dual connectivity instruction to the core network device through the mobility management unit.

Optionally, the first message may be a radio Access Modification indication message (e.g., an E-utran radio Access Bearer (E-RAB) Modification indication (Modification indication) or another newly defined message, which is not limited in this application.

Optionally, the first message includes a dual connectivity indication, where the dual connectivity indication is used to indicate that the UE accessing the base station by the core network device enters a dual connectivity state, and the primary base station and the secondary base station have different standards.

As a possible implementation manner, the dual connectivity indication may include a standard of the first base station and a standard of the second base station, for example, the first base station is a 4G base station, and the second base station is a 5G base station; or the first base station is a 5G base station, and the second base station is a 4G base station; or the first base station is a 5G base station, and the second base station is a 3G base station, etc., which are not limited in this application.

As another possible implementation manner, in a case that the core network device knows the format of the first base station, the dual connectivity indication may include the format of the second base station. For example, taking the core network device that has determined that the format of the first base station is the 4G base station as an example, the dual connectivity instruction may also indicate that the format of the second base station is the 5G base station.

In addition, the dual connectivity indication in this application may indicate, in addition to indicating to the core network device that the terminal device enters the dual connectivity state, that the core network device activates a new charging rule, for example, indicate that the core network device uses a different rate than the first base station for data to be transmitted through the second base station, and indicate that the data to be transmitted through the second base station uses a different charging container than the first base station.

S102, the core network equipment receives the double-connection indication sent by the first base station.

Optionally, the mobility management unit obtains a dual connectivity indication sent by the first base station from a radio Access modification indication message (e.g., a radio Access Bearer (E-RAB) modification indication (modification indication) or other newly defined messages.

S103, the core network equipment sends a first instruction to the first base station.

Optionally, in order to enable a period in which the first base station reports the first statistical information to be consistent with a period in which the core network device reports the second statistical information, or a period in which the first base station reports the first statistical information to be consistent with a period in which the core network device obtains the third statistical information, the first indication in the present application may be used to indicate that the first base station determines that the reporting period of the first statistical information is the first period.

As a possible implementation, the values of the first period and the second period are the same.

It should be noted that, in the present application, a period in which the first base station reports the first statistical information and a period in which the core network device obtains the third statistical information are consistent, and at least one of the following conditions is satisfied: the deadline for the first base station to count the first statistical information in a first period is the same as the deadline for the core network device to count the third statistical information in a second period, and the start time for the first base station to count the first statistical information in the first period is the same as the start time for the core network device to count the third statistical information in the second period.

In the present application, a period of reporting the first statistical information by the first base station and a period of reporting the second statistical information by the core network device are consistent and satisfy at least one of the following conditions: the second time when the first base station reports the first statistical information in a first period is the same as the first time when the core network device reports the second statistical information in a second period, and the deadline time when the first base station counts the first period in the first period is the same as the deadline time when the core network device reports the second statistical information in the first period, and the second statistical information lasts for the same deadline time in the second period.

For example, if the deadline of the second statistic information is P in the period T1, then in order to make the periods of the first statistic information and the second statistic information consistent, after the first base station reports the first statistic information in a first period, the deadline of the first statistic information should also be P.

It should be noted that, in the actual process, the process of acquiring the third statistical information by the core network device, the process of reporting the second statistical information by the core network device, and the process of counting the first statistical information by the first base station or the second base station may be performed in parallel, where in this application, it may be considered that the signaling connection time between the first base station or the second base station and the core network device is zero, and the signaling connection time between the core network device and the charging system is zero; or the first base station or the second base station and the core network device, the core network device and the charging system may compensate according to the time difference caused by signaling transmission, and the reference point of the feedback time point or duration is consistent.

It should be noted that, in an actual process, the first base station determines, according to the first indication, that a period of reporting the first statistical information is a first period, which generally corresponds to the following scenario:

in a first scenario, when the core network device receives a dual connectivity indication sent by the first base station, the core network device is to count third statistical information in a second period (the third statistical information may be used as second statistical information before the core network device receives the dual connectivity indication sent by the first base station), or the core network device is to start to count the third statistical information in the second period, that is, when the core network device receives the dual connectivity indication, the core network device is in a process of counting the third statistical information in the first second period (for example, the current second period) that is counted up, that is, the core network device is to start to count the second statistical information in the second period (the next second period of the current second period). In this case, the core network device may indicate, to the first base station, the second period as the first period through the first indication, so that a period in which the first base station reports the first statistical information is consistent with a period in which the core network device reports the second statistical information.

Illustratively, as shown in fig. 10: in fig. 10, taking the second period as T1, the first period as T2, the second statistical information as CDR, and the first statistical information as Usage Report (UR), as an example, if the first time at which the core network device reports the CDR4 in the third T1 period shown in fig. 10 is the same as the second time at which the first base station reports the UR1 in the first T2 period, or if the second time at which the core network device reports the second statistical information is within a preset error as the first time at which the first base station reports the first statistical information, it may be ensured that the duration of the first statistical information from the second time in a first period is the same as the duration of the second statistical information from the first time in a second period, that is, the second time at which the first base station reports the first statistical information in a first period is the same as the first time at which the core network device reports the second statistical information in a second period, the expiration time of the first statistical information in a first period is the same as the expiration time of the second statistical information in a second period.

It should be noted that, in the present application, after receiving the dual connectivity indication sent by the first base station, the core network device may also use the third statistical information as the second statistical information, that is, the core network device does not process the third statistical information and the first statistical information.

However, in an actual process, when the first base station sends the dual connectivity indication to the core network device, there may be the following situations: during the first second period, the core network device is continuously counting the third statistical information. Thus, when the first period and the second period are the same, there may be a case as shown in fig. 11: the second time when the core network device reports the CDR4 in the second period is different from the first time when the first base station reports the UR1 in the first period, or there is a time difference (for example, the core network device has already started reporting the CDR4 in the second period, if the time that the CDR4 has lasted is t, and the first base station only starts reporting the UR1 to the core network device at the first time in the first period after the first indication is triggered), so that if the first base station still uses the first period to report the first statistical information in the first period and the second period are the same, there is a time difference t between the first statistical information in any one of the subsequent first periods and the second statistical information in the second period. Therefore, to solve this problem, the method provided by the present application is also applicable to scenario two and scenario three:

and in a second scenario, when the core network device receives the dual connectivity indication, the core network device adjusts second statistical information which is continuing in a second period, and sends a first indication to the first base station.

And a third scenario, when the core network device receives the dual connectivity indication, the core network device keeps a period of the second statistical information which is continuously in a second period unchanged, and sends a first indication to the first base station, so that the first base station adjusts the period of the first statistical information in a period.

The continuous second statistic information is understood as that the deadline of the current second period is not yet reached, and accordingly, the statistics of the third statistic information in the current second period is not ended at the current time.

Since the content of the first indication sent by the core network device to the first base station is different in different scenarios, the following descriptions will be separately introduced in conjunction with the different scenarios:

optionally, the first indication in this application is used to instruct the first base station to determine the second period as the first period.

In the first scenario and the second scenario, for the first base station, the first base station may not adjust a period of reporting the first statistical information, and therefore, in the first scenario and the second scenario, the content of the first indication sent by the core network device to the first base station may be the same, but in an actual process, the first base station may have a second period or may not have the second period, and therefore the following description will be introduced in a unified manner with reference to whether the first scenario, the second scenario, and the first base station have the second period:

in scenarios one and two, the first base station has a second period, and when the core network device determines that the first base station has the second period configured in advance:

as a possible implementation manner, the first indication may be a message, e.g., a first response message, made by the core network device for the dual connectivity indication.

As another possible implementation manner, the first indication may be information indicating a second periodicity, where the information indicating the second periodicity is used for determining the second periodicity.

Optionally, the information indicating the second period may be at least one of an index (index) and the second period, where the index is used to determine the second period.

For example, the first base station has preconfigured information, where the preconfigured information at least stores an association relationship between the second period and the index, so that the core network device may send the index to the first base station through the first indication, and after receiving the first indication, the first base station may determine the second period associated with the index as the first period.

It is to be understood that, when the first base station has a second period configured in advance, the first indication may also be the second period, which is not limited in this application.

Specifically, the second period preconfigured in the first base station may be obtained by:

as a possible implementation manner, the second period preconfigured in the first base station may be configured by a network or an operator.

As another possible implementation manner, the second period preconfigured in the first base station may be a second period sent to the first base station by the core network device in the process of creating the dual connectivity, or obtained in other flows before the first base station creates the dual connectivity, such as a registration flow and a session creation flow, which is not limited in this application.

In a third scenario, in order to make a first period in which the first base station reports the first statistical information consistent with a second period in which the core network device reports the second statistical information, the first base station may adjust a period in which the first base station reports the first statistical information to the core network device within a first period (for example, the statistical information that the first base station reports to the core network device for the first time is referred to as a fourth statistical information), it is understood that in an actual process, the statistical information is not limited to the statistical information that is reported to the core network device for the first time, but may be any statistical information in a process in which the main base station reports the statistical information to the core network device), therefore, the first indication in this application is also used to instruct the first base station to determine the third period, the third period is a period of statistical information reported by the first base station to the core network device for the first time after receiving the dual connectivity indication.

As a possible implementation manner, the first indication may be a first time parameter, where the first time parameter is used for the first base station to determine a third period of the fourth statistical information, and the second period is determined as the first period.

As another possible implementation, the first indication may be a first time parameter and information indicating a second periodicity.

Specifically, in the second scenario, as shown in fig. 12, step S103 provided by the present application may be specifically implemented in the following manner:

and S103, the core network equipment sends a first indication to the first base station in the process of starting to count the third statistical information or reporting the second statistical information in a second period.

It should be noted that the step S103 can be specifically implemented by: the core network device sends a first indication to the first base station in the process of closing third statistical information which is being counted in a first second period and opening third statistical information which needs to be counted in a second period, wherein the second period is a second period after the first second period.

The first second period may be a current second period, that is, a second period in which the third statistical information is being counted when the core network device receives the dual connectivity indication, and the second period may be a next second period after the current second period.

For example, as shown in fig. 13, the second period is T1 and the first period is T2 in fig. 13 for illustration: as can be seen from fig. 13, when the core network device receives the dual connectivity indication, the CDR3 is being counted in a T1 period, and the CDR3 has lasted for a T period of time in a T1 period, so that, in order to make a first period in which the first base station reports the first statistical information and a second period in which the core network device reports the second statistical information coincide, the core network device may turn off the CDR3 being counted in a current T1 period and start counting the CDR4 in a next T1 period. As shown in FIG. 13, the T1 period of CDR3 is actually adjusted to T by T1.

As another possible implementation manner, when the method provided by the present application is applied to the architecture shown in fig. 5 or fig. 6, the step S103 provided by the present application may be specifically implemented by:

and S103, the core network equipment starts to count the third statistical information in a second period under the trigger of the double-connection indication sent by the first base station, and sends the first indication to the first base station.

Optionally, the second period corresponds to a first period in which the first base station reports the first statistical information to the core network device for the first time.

As another possible implementation manner, when the method provided by the present application is applied to the architecture shown in fig. 5 or fig. 6, the core network device includes a serving gateway SGW, where the SGW includes a serving gateway control plane SGW-C and a serving gateway user plane SGW-U, and step S103 may be specifically implemented by:

and the SGW-C sends the double connection instruction to the SGW-U, the SGW-U starts to count the third statistical information in a second period, and sends a notification message to the SGW-C, wherein the notification message is used for triggering the SGW-C to send the first instruction or informing the SGW-C that the third statistical information in the second period is restarted.

It is understood that before the SGW-U starts to count the third statistic in a second period, the SGW-U turns off the third statistic being counted in the current second period according to the dual connection indication.

In the present application, the statistical period for the core network device to acquire the third statistical information is the same as the period for the core network device to report the second statistical information to the charging system, that is, the statistical period for the core network device to acquire the third statistical information is the second period.

S104, the first base station receives a first instruction sent by the core network equipment.

And S105, the first base station determines a first period according to the first indication, wherein the first period is the same as a second period of the second statistical information reported by the core network equipment.

Since there is a difference in the manner in which the first base station determines that the period for reporting the first statistical information is the first period in the first scenario, the second scenario, and the third scenario, the following description will be separately given:

in the first and second scenarios, step S105 may be specifically implemented in the following manner:

s1051a, the first base station determines the second period as the first period according to the first indication.

Optionally, when the first indication is a message, for example, a first response message, that is, the first response message itself has an indication function, the first base station determines the second preconfigured period as the first period.

Optionally, when the first indication is information indicating a second period, the first base station determines the second period as the first period.

For example, if the information indicating the second period is an index, the first base station determines the preconfigured second period associated with the index as the first period.

For example, the information indicating the second period is the second period, and the first base station determines the second period as the first period.

In the third scenario, step S105 may be specifically implemented by:

s1051b, the first base station determines that the first indication includes the first time parameter, and the first base station determines a second period configured in advance as the first period.

It can be understood that the first time parameter in this application is used to instruct the first base station to determine the third period of the first statistical information that is first reported to the core network device, so that when the first base station determines that the first indication includes the first time parameter, the first base station may determine, according to the first indication, not only the second period that is preconfigured as the first period, but also the third period of the fourth statistical information that is first reported to the core network device. This is typically true for the first base station being preconfigured with a second periodicity. Therefore, the first time parameter is carried in the first indication, so that the first base station can determine the third period of the fourth statistical information reported to the core network device for the first time, and also can determine the first period of the first statistical information reported to the core network device after the first time, thereby reducing signaling overhead.

S1052b, when the first base station determines that the first indication includes the first time parameter and the information indicating the second period, the first base station determines the second period as the first period according to the information indicating the second period.

It can be understood that, when the first indication includes both the first time parameter and the information indicating the second period, the first base station may determine, according to the first indication, not only the second period as the first period, but also determine a third period of fourth statistical information that is first reported to the core network device. This is applicable to both the case where the preconfigured second period exists in the first base station and the case where the preconfigured second period does not exist in the first base station, and when the preconfigured second period does not exist in the first base station, the information indicating the second period in step S1052b may be the second period in general.

S106, the first base station reports first statistical information to the core network equipment, wherein the first statistical information is obtained according to a first period.

In the architectures shown in fig. 4 and fig. 6, the secondary base station may also report the first statistical information to the core network device through the primary base station, so that the reporting of the first statistical information to the core network device by the first base station may be counted by the first base station or counted by the second base station, which is not limited in this application.

The following description will be given taking an example in which the first statistical information is obtained by the first base station according to the first period:

when step S105 is implemented by S1051a, step S106 in the present application can be specifically implemented by:

s1061a, the first base station starts reporting the first statistical information according to the first period after receiving the first indication.

For example, as shown in fig. 13, the first base station reports the first statistical information to the core network device periodically with T2 as a first period, for example, the periods of UR1, UR2, UR3, and UR4 are all periods T2, where a period T2 corresponding to each piece of first statistical information coincides with a period T1 corresponding to one piece of second statistical information, for example, < CDR4, UR1>, < CDR5, UR2>, < CDR < 6, UR3 >.

When the step S105 is implemented by S1051b or S1052b, the step S106 in the present application may be specifically implemented by:

since there may be a fourth statistical information when the first base station reports the first statistical information to the core network device periodically according to the first period, and the reporting period of the fourth statistical information is less than the first period. Therefore, when the step S105 is implemented by S1051b or S1052b, the step S106 in the present application can be specifically implemented by:

s1061b, the first base station determines a third period according to the first period and/or the first time parameter, determines fourth statistical information according to the third period, and reports the fourth statistical information to the core network device according to the third period.

It should be noted that, the third period in this application may be understood as a time period, where the time period is used to report the fourth statistical information, and after the first base station reports the fourth statistical information to the core network device for the first time, the subsequent first base station will report the first statistical information to the core network device periodically according to the first period.

On one hand, since the content of the first time parameter is different, and there is a difference in the manner in which the first base station determines the third period according to the first period and/or the first time parameter, a specific implementation process in which the first base station determines the third period according to the first period and/or the first time parameter will be described below:

in a possible implementation manner, the first time parameter is used to determine a remaining time period of the core network device in a second period, and then the first base station may specifically determine the third period according to the first period and/or the first time parameter by the following means:

the first base station determines a residual time period according to the first time parameter; and the first base station determines the residual time period as a third period according to the first time parameter.

Optionally, the first time parameter may be at least one of a remaining time period of the core network device in a second period, a start time of the core network device in the second period, a time period that the core network device has lasted in the second period, and an expiration time of the core network device in the second period.

Optionally, the first base station determines the remaining time period according to the first time parameter, and may be implemented in the following manner:

on one hand, if the first time parameter is the remaining time period, the first base station determines the remaining time period from the first time parameter.

On the other hand, if the first time parameter is the deadline, the first base station determines a time difference between the current time and the deadline as the remaining time period.

In yet another aspect, the first time parameter is a start time, the first base station determines a time period that has continued according to the current time and the start time, and determines a time difference between the first period and the time period that has continued as the remaining time period.

In yet another aspect, the first time parameter is a time period that has been sustained, and the first base station determines a time difference between the first period and the time period that has been sustained as the remaining time period.

In order to reduce the time delay, the first time parameter in the present application may be calculated by the core network device and then sent to the first base station, that is, the core network device may directly send the remaining time period to the first base station.

Of course, the core network device may also send the parameter to the first base station for calculating the remaining time period of the core network device in the second period, and the first base station calculates the remaining time period by itself, which is not limited in this application.

In another possible implementation manner, the first time parameter is used to determine a time period that the core network device has lasted within a second period, and then the first base station may specifically determine, according to the first period and/or the first time parameter, the third period by the following means:

the first base station determines a time period which lasts according to the first time parameter; the first base station determines as a third cycle according to a time difference between the second cycle and the already-continued time period.

Optionally, the first base station determines the sustained time period according to the first time parameter, which may be specifically implemented in the following manner:

in one aspect, the first time parameter is a time period that has been sustained, and the first base station determines the time period that has been sustained in the first time parameter.

On the other hand, the first time parameter is the starting time, and the first base station determines the time period which lasts according to the time difference between the current time and the starting time.

In still another aspect, the first time parameter is a remaining time period, and the first base station is configured to be a time period that has been continued according to a time difference between the first period and the remaining time period.

It should be noted that, since the value of the third period is usually smaller than the value of the first period, after the third period is determined, the first base station also needs to determine first statistical information, for example, fourth statistical information, which is reported to the core network device for the first time.

For example, as shown in fig. 14, when the first base station sends the dual connectivity indication, the core network device uses T as a time period for which the CDR4 reported in a T1 period has been continued, and the first base station determines, according to the first time parameter, that T3 is T1-T, then the first base station reports UR1 in a T3 period, and after reporting UR1, reports UR2 and UR3 in a period according to T2, so that each piece of first statistical information is finally consistent with one piece of second statistical information, for example, < CDR4, UR1>, < CDR5, UR2>, < CDR6, UR3 >.

S107, the core network equipment receives the first statistic information reported by the first base station.

When the first statistical information is obtained by statistics of the first base station, step S107 may be specifically implemented by: the first base station reports the first statistical information to the core network equipment according to the first period.

When the first statistical information is obtained by statistics of the second base station, step S107 may be specifically implemented by: the core network equipment receives first statistical information which is sent by the first base station and is counted by the second base station according to the first period.

Optionally, when the first base station reports the first statistical information in the manner of step S1061b, before step S107, the method provided in this application further includes: and the core network equipment receives fourth statistical information which is sent by the first base station and is counted according to the third period.

As shown in fig. 4 and fig. 6, because there is also a data plane connection between the secondary base station and the core network device and the data does not pass through the primary base station, the secondary base station may also count the first statistical information and report the first statistical information counted by the secondary base station to the core network device through the primary base station, as shown in fig. 15, before step S106, the method provided in this application further includes:

s108, the first base station sends a second instruction to the second base station.

The content of the second indication may refer to the content of the first indication, which is not described herein again, and of course, the second indication may also be the first indication sent by the core network device to the first base station.

And S109, the second base station determines the period of reporting the first statistical information as a first period according to the second indication, wherein the first period is the same as a second period of reporting the second statistical information by the core network equipment.

Specifically, for the process of determining, by the second base station, that the period for reporting the first statistical information is the first period, reference may be made to the process of determining, by the first base station, the first period in the above embodiment, which is not described herein again.

And S110, the second base station reports the first statistical information to the core network equipment through the first base station according to the first period.

Specifically, for a specific implementation process of step S110, reference may be made to the process in which the first base station sends the first statistical information to the core network device according to the first period, which is not described herein again.

It is to be understood that, in a practical process, the second indication may also include the first period determined by the first base station, and the application is not limited herein. When the second indication sent by the first base station to the second base station is not the first period in this application, step S105 may be omitted.

In the above process of describing how the first base station sends the first statistical information to the core network device by using the first base station as a main base station as an example, in the architectures shown in fig. 3 to 6, the secondary base station may also count the first statistical information, but since there is no control plane connection between the secondary base station and the core network device, the first statistical information counted by the secondary base station may be sent to the core network device through the main base station, so as to serve as another embodiment of the present application:

when the secondary base station reports the first statistical information to the core network device, the first base station may perform S108 to S110 first and then perform S106 after receiving the first indication.

It should be noted that, in the present application, when the primary base station sends the first statistical information to the core network device, the primary base station may further carry indication information, where the indication information is used to indicate that the core network device is counted by the primary base station or counted by the secondary base station.

In the following, the first statistical information is reported to the core network device by the master base station according to the first period, and the 4G communication system architecture is taken as an example for description, it is understood that, in an actual process, the present application may also be applicable to communication system architectures of other systems, for example, a 5G communication system architecture, and when the present application is applied to a 5G communication system, the MME may be an AMF entity, and the SGW may be a UPF entity. In the framework shown in fig. 3, for scenario two, the method for reporting information provided in the embodiment of the present application may be shown in fig. 16, and includes the following steps:

s201, the main base station selects the auxiliary base station, and in the process of establishing the dual connectivity, the main base station sends a dual connectivity instruction to the MME.

Specifically, the manner in which the main base station sends the dual connectivity indication to the MME may be described in the above embodiments, and details of this application are not described herein again.

The process of selecting the secondary base station by the primary base station may be referred to in the prior art, and the present application is not limited thereto.

S202, the MME receives the dual-connection indication sent by the main base station.

S203, the MME sends a dual connectivity instruction to the SGW.

Optionally, the MME sends the dual connectivity indication to the SGW by using a signaling message, for example, a bearer modification request message modify bearer request or other newly defined messages, which is not limited in this application. The dual connectivity indication sent to the SGW by the MME may be the dual connectivity indication received from the main base station, which is processed by some signaling encapsulation and modification of expression form, or the dual connectivity indication sent to the MME by the main base station.

S204a, the SGW closes the third statistical information being counted in the current second period according to the dual connection indication, and starts to count the third statistical information in a second period after the current second period.

It can be understood that, when the SGW receives the dual connectivity indication, if the SGW has the third statistical information being counted in the current second period, the SGW closes (stops) the third statistical information being counted in the current second period, starts a new second period, and counts the third statistical information in the new second period.

S205a, in the process that the SGW closes the third statistical information being counted in the current second period and starts to count the third statistical information in a new second period, the SGW sends a first indication to the MME, where the first indication is used to indicate that the main base station determines the period for reporting the first statistical information.

Optionally, the first indication may be a flag cell, or some feature bits, etc. to indicate that the MME has completed the operation required to create the dual connectivity, and the main base station needs to report the first statistical information.

Optionally, the first indication may include a second period, for example, the second period may be used as the first indication.

The SGW may use a signaling message sent to the MME as a first indication, such as a bearer modification response.

Specifically, the content of the first indication may refer to the foregoing embodiments, and is not described herein again.

S206, the MME sends a first instruction to the main base station.

Optionally, the MME may send the first indication to the master base station through a signaling message, where the first indication may be sent by the SGW to the MME or sent to the master base station after encapsulating the first indication sent by the SGW to the MME.

Optionally, the MME may use a signaling message sent to the main base station as the first indication, for example, a signaling message sent by the MME to the main base station, such as an E-RAB modification confirmation.

S207, the main base station receives the first indication sent by the MME.

S208a, the master base station determines the period of the first statistical information as the first period according to the first indication.

Specifically, the main base station determines that the period of the first statistical information is the first period, and reference may be made to the process of determining the first period by the first base station in the foregoing embodiment, which is not described herein again.

S209a, the primary base station reports the first statistical information to the primary base station according to a first period, where the first period is consistent with a second period for the SGW to report the second statistical information to the charging system.

Optionally, the first period and the second period of the second statistical information reported by the SGW are consistent: the values of the first period and the second period are equal, and the deadline of the first statistical information in the first period is the same as the deadline of the second statistical information or the third statistical information in the second period.

It can be understood that, in the scene, in the process of reporting the first statistical information by the master base station in the subsequent process, the master base station periodically reports the first statistical information to the MME according to a first period indicated by the first indication sent by the MME.

S210, the MME receives first statistic information reported by the main base station according to a first period.

S211, the MME sends the first statistic information to the SGW.

Specifically, a specific implementation manner for the MME to send the first statistical information to the SGW may refer to the prior art, and is not described herein again.

S212, the SGW processes the first statistical information and the third statistical information, and sends the processed first statistical information and third statistical information to the charging system as second statistical information according to the first period. And the third statistical information is information counted by the SGW according to the second period.

Specifically, the MME processing the first statistical information and the third statistical information means: after integrating the first statistical information counted by the first base station according to the first period and the third statistical information counted by the SGW according to the second period in the same time period in time, the SGW sends the time-integrated first statistical information and the third statistical information counted by the SGW in the second period corresponding to the first period to the charging system as second statistical information, that is, the first statistical information reported by the main base station in the first period is integrated with the third statistical information counted by the SGW in the second period corresponding to the first period in time. For example, the second statistical information may be < CDR4, UR1> in fig. 14, which is not described herein again.

Wherein one period of time is a first cycle or a second cycle.

In addition, as another embodiment of the present application, in an architecture where the SGW shown in fig. 5 is a structure where the control plane and the user plane are separated, since the SGW-U needs to report the counted third statistical information to the SGW-C and report the third statistical information to the charging system by the SGW-C, as shown in fig. 17, fig. 17 shows a flowchart of another method for reporting information in the present application, and a difference between fig. 17 and fig. 16 is that: step S204b is used in fig. 17 instead of step S204a in fig. 16, step S205b is also used in fig. 17 instead of step S205a, and steps S213 and S214 are also included before step S212:

step S204b may be specifically implemented in the following manner: the SGW-C sends the received dual connectivity indication sent by the MME to the SGW-U, and the SGW-U turns off the third statistical information being counted in the current second period, and starts to count the third statistical information in the next second period of the current second period and sends a message (for example, the message may be a response message) to the SGW-C, where the message may trigger the SGW-C to send the first indication or inform the SGW-C that the third statistical information in one second period has been turned on again.

Specifically, the SGW-C may send the received dual connectivity indication sent by the MME to the SGW-U through a session management request message (session creation or modification request).

Step S205b may be implemented by: the SGW-C sends a first indication to the MME.

And S213, the SGW-U sends the third statistical information obtained by statistics according to the second period to the SGW-C.

S214, the SGW-C receives third statistical information which is obtained by the SGW-U according to the second period.

On the other hand, as another embodiment in the present application, taking the following example that the main base station reports the first statistical information to the core network device according to the first period, and the 4G communication system architecture as an example, it can be understood that, in an actual process, the present application may also be applied to communication system architectures of other systems, for example, a 5G communication system architecture, and when the present application is applied to a 5G communication system, the MME may be an AMF entity, and the SGW may be a UPF entity. In the architecture shown in fig. 3, for scenario three, as shown in fig. 18, the difference between fig. 18 and fig. 16 is: in fig. 18, step S204c is used instead of S204a in fig. 16, step S205c is used instead of step S205a in fig. 16, step S208b is used instead of S208a in fig. 16, and step S209b is used instead of step S209a in fig. 16:

s204c, the SGW maintains the third statistical information being counted in the current second period according to the dual connection indication.

S205c, the SGW sends a first indication to the MME, where the first indication includes the first time parameter, or the first time parameter and information indicating the second periodicity.

Optionally, the first time parameter is used to indicate that a remaining time period of the SGW in one second cycle is determined as the third cycle, or the first time parameter is used to indicate that a time period of the SGW which has lasted in one second cycle is determined as the third cycle.

Optionally, the first time parameter may be a remaining time period of the SGW in a second period, a time period that the SGW has lasted in the second period, a start time of the SGW in the second period, and an end time of the SGW in the second period.

Accordingly, step S208b in the present application can be implemented by:

the master base station determines a third period based on the first time parameter.

Specifically, the manner in which the master base station determines the third period according to the first time parameter may be referred to in the foregoing embodiments, and details of this application are not described herein again.

S209b, the primary base station determines the fourth statistical information according to the third period, reports the fourth statistical information according to the third period, and reports the first statistical information according to the first period after reporting the fourth statistical information.

In another aspect, as another embodiment of the present application, in the architectures shown in fig. 5 and fig. 6, in which the SGW is an architecture in which a control plane and a user plane are separated, since the SGW-U needs to report the counted third statistical information to the SGW-C, and the SGW-C integrates the third statistical information and the first statistical information and reports the third statistical information to the charging system, as shown in fig. 19, fig. 19 shows a flowchart of another method for reporting information in the present application, and a difference between fig. 19 and fig. 18 is that: step S204d is used in fig. 18 instead of step S204c in fig. 18, step S205d is used instead of S205c in fig. 18, and further, step S213 is included before step S212.

S204d may be specifically implemented in the following manner: and the SGW-C sends the received double-connection indication sent by the MME to the SGW-U, the SGW-U keeps the current third statistical information which is being counted in the second period, and sends a response message to the SGW-C, wherein the response message can carry the first time parameter and information used for indicating the second period, or carry the first time parameter.

It is understood that, in the case of having the second period and the first time parameter in the SGW-C, the response message may not carry the first time parameter and information indicating the second period, or carry the first time parameter. That is, the SGW-U may use the response message of the dual connectivity indication sent by the SGW-C as a basis for triggering the SGW-C to send the first indication to the master base station through the MME.

S205d, the SGW-C sends a first indication to the MME, where the first indication carries the first time parameter and information indicating the second period, or carries the first time parameter.

Since the SGW-U maintains the third statistical information that the current second period is counting in the present embodiment, step S204d may be omitted in the case of having the second period and the first time parameter in the SGW-C.

In addition, in the architectures shown in fig. 4 and fig. 6, not only the primary base station may report the first statistical information to the core network device by using the above method, but also the secondary base station may report the first statistical information counted by the secondary base station side to the primary base station, so that the primary base station sends the first statistical information counted by the secondary base station side according to the first period to the core network device. It can be understood that, the core network device counts the total statistical information of the main base station and the secondary base station, and therefore, after receiving the first statistical information sent by any one of the main base station and the secondary base station, the core network device may determine the first statistical information of the other base station, so as to configure different charging policies for the secondary base station. For example, if the core network device receives the first statistical information counted by the primary base station, the core network device may determine the first statistical information of the secondary base station according to the total statistical information and the first statistical information counted by the primary base station.

As another embodiment in the present application, taking the application of the method provided in the present application to the communication network architecture shown in fig. 4 as an example, regarding scenario two, as shown in fig. 20, the difference between fig. 20 and fig. 16 is: in fig. 20, step S215 is added after step S206 and step S216 and step S217 are added before step S210, and in addition, steps S207 to S209a are executed by the secondary base station, and specific implementation processes of the respective steps may refer to the description of the above embodiment, which is not described herein again.

Wherein, S215, the primary base station transmits the second indication to the secondary base station.

It can be understood that the second indication sent by the main base station to the secondary base station may be a first indication sent by the MME to the main base station, or the first indication sent by the MME may be sent to the secondary base station after being encapsulated or modified by the main base station, and in a scenario where the main base station sends the first indication to the secondary base station, the first indication sent by the main base station to the secondary base station may carry the first period, that is, the main base station may calculate the first period and/or the third period according to the first time parameter carried in the first indication sent by the MME, and then send the first period and/or the third period to the secondary base station.

S216, the main base station receives first statistic information which is sent by the auxiliary base station and counted according to the first period.

It can be understood that, if the fourth statistical information exists before the secondary base station reports the first statistical information counted according to the first period to the primary base station, step S216 further includes: and the main base station receives fourth statistical information which is sent by the auxiliary base station and is counted according to the third period.

S217, the main base station sends first statistical information which is reported by the auxiliary base station and counted according to the first period to the MME.

When step S216 further includes: when the primary base station receives the fourth statistical information according to the third period statistics sent by the secondary base station, step S217 may be implemented by: and after the main base station sends the fourth statistical information counted by the auxiliary base station according to the third period to the MME, sending the first statistical information counted according to the first period reported by the auxiliary base station to the MME.

It should be noted that in a scenario where the secondary base station reports the first statistical information, the SGW also supports a structure where a user plane and a control plane are separated, and therefore, in the scenario where the secondary base station reports the first statistical information, specific actions of the secondary base station side may refer to fig. 17, fig. 18, and fig. 19, which is not described herein again.

In addition, in the present application, the secondary base station and the master base station may both report respective first statistical information to the MME according to the above-described procedure, at this time, when the master base station sends, to the MME, first statistical information counted by the master base station according to the first period and first statistical information counted by the secondary base station according to the first period, it is further required to send, to the MME, first indication information for indicating the SGW to distinguish which first statistical information is counted by the master base station and which first statistical information is counted by the secondary base station, for example, the first indication information may be an association between the first statistical information counted by the master base station according to the first period and a first identifier, and the secondary base station may be an association between the first statistical information counted by the primary base station according to the first period and a second identifier, where the first identifier is used to determine that the first statistical information is counted by the master base station according to the first period, the second identifier is used to determine that the first statistical information is counted by the secondary base station.
