In the following description, for purposes of illustration and description, reference

Referring to FIG. 1, FIG. 1 is a flowchart of an implementation manner of a service management method according to the present application. The execution entity of this embodiment is a base station, and the base station may be a cluster base station or other base stations. The service management method of this embodiment includes the following steps:

S101: The base station synchronizes data of the network side to the local database, where the data includes a service type and a service status of the network side, where the service is a service requested by a terminal accessing the core network.

After the terminal accesses the base station and accesses the core network through the base station, the base station obtains the service type and service status requested by all the terminals accessing the core network from the core network every preset time, and obtains the service type and service. Status synchronization is saved to the local database. The preset time can be set according to actual needs, and is not limited herein.

For example, when the service requested by the terminal accessing the base station is to download a file from the core network, the base station saves the data included in the file and the download progress to the local database for backup, so that when the base station and the core network are The communication link between the two is interrupted. And when the file download is completed, the base station can send the data included in the downloaded file to the terminal.

S102: Enter a fault weakening mode when detecting that the communication link with the core network is interrupted.

When the base station detects that the communication link between the base station and the core network is interrupted, that is, the base station cannot communicate with the core network, the base station switches the current working mode from the normal mode to the fault weakening mode.

Optionally, after the base station enters the fault weakening mode, the broadcast information may be sent to the terminal accessing the base station, where the broadcast information is used to identify the entry fault weakening mode of the base station, so that the terminal after receiving the broadcast information The service that needs to be accessed through the base station to access the core network is filtered, and the service that can be completed only through the base station is reserved.

S103: Determine, according to the data in the local database, whether the service requested by the terminal accessing the base station is supported in the fault weakening mode.

After the base station enters the fault weakening mode, the data that is synchronously saved from the core network is obtained from the local database, and whether the base station supports the service requested by the terminal of the access base station in the fault weakening mode is determined according to the synchronously saved data. The data stored in synchronization includes the service type and service status requested by all terminals accessing the core network.

The service requested by the terminal accessing the base station includes accessing the service of the base station entering the fault weakening mode, accessing other services (other than the base station entering the fault weakening mode), and accessing the service of the core network through any base station.

When the service requested by the terminal accessing the base station is a service that can be completed only by the base station in the fault weakening mode, the service is determined to be a service supported by the base station.

When the service requested by the terminal accessing the base station is a service that can be implemented by another base station, or a service that is implemented by the base station in the fault weakening mode and other base stations, or a service that can be realized by accessing the core network by any base station, determine the service. The service is a service that the base station does not support.

When the result of the determination is that the current service is a service supported by the base station, step S104 is performed.

When the result of the judgment is that the current service is a service that is not supported by the base station, no processing is performed on the service, and the process returns to step S103 to determine whether the acquired next service is a service supported by the base station.

Optionally, when the result of the determination is that the current service is a service that is not supported by the base station, the related data included in the service that is not supported by the base station is cleared, and the process returns to step S103. When the current service of the terminal is a service that is not supported by the base station, the base station disconnects the communication link between the base station and the terminal, and controls the terminal to enter a sleep state.

S104: When the service is supported, the service is managed to maintain the connection state of the terminal.

When the result of the judgment is that the current service of the terminal is the service supported by the base station, the base station takes over the service state machine corresponding to the supported service to manage the supported service, and maintains the communication link between the base station and the terminal, so that the terminal maintains the connection. status.

It can be understood that the management-supported service includes obtaining data of the supported service and the status of the service from the data of the local database, managing the service status of the service, and related data of the current service.

S201: The base station synchronizes data of the network side to the local database, where the data includes a service type and a service status of the network side, where the service is a service requested by a terminal accessing the core network.

S202: Enter a fault weakening mode when detecting that the communication link with the core network is interrupted.

Optionally, after the base station enters the fault weakening mode, the broadcast information may be sent to the terminal accessing the base station, where the broadcast information is used to identify the entry fault weakening mode of the base station, so that the terminal after receiving the broadcast information The service that needs to be accessed by the base station to access the core network is filtered, and the service that can be completed only by one base station or multiple base stations is reserved.

S203: Reconfigure the security encryption mode, so that the terminal updates the security encryption mode, and sends an access request by using the security encryption mode.

After the base station enters the fault weakening mode, the base station is triggered to reconfigure the security encryption mode, so that the terminal accessing the base station sends an access request by using a method corresponding to the reconfigured security encryption mode to access the base station and continue the current service or request. new business.

Optionally, for the mobile terminal in the dormant state, after the base station reconfigures the security encryption mode, after the paging moment of the self receives the reconfigured security encryption mode information sent by the base station after entering the fault weakening mode, the reconfigured The method corresponding to the security encryption mode sends an access request to access the base station to send a service request.

The base station in the fault weakening mode can only implement the functions of scheduling the local area network or the private network. Therefore, the security encryption mode of the base station reconfiguration in the fault weakening mode is simpler than the security encryption mode in the normal mode.

S204: Determine, according to the data in the local database, whether the service requested by the terminal accessing the base station is supported in the fault weakening mode.

When the result of the judgment is that the current service of the terminal is the service supported by the base station, the base station takes over the service state machine corresponding to the supported service to manage the supported service, and maintains the communication link between the base station and the terminal, so that the terminal maintains the connection state. .

S206: When the service is not supported, the service is cleared, and the terminal is put into a sleep state.

When the result of the judgment is that the current service is a service that is not supported by the base station, the related data included in the service is cleared. When the current service of the terminal is a service that is not supported by the base station, the base station disconnects the communication link between the base station and the terminal, and controls the terminal to enter a sleep state.

The terminal that enters the dormant state can send an access request to the base station by using the security encryption mode corresponding to the normal mode after the base station is switched from the fault weakening mode to the normal mode, and the access request can be sent by the method corresponding to the reconfigured security encryption mode. To access the base station to send a service request.

Certainly, when the terminal that enters the dormant state receives the security encryption mode information or the reconfigured security encryption mode information of the other base station at the paging occasion, the terminal sends an access request according to the received security encryption mode. The base station that sends the security encryption mode information sends a service request.

In the above solution, the base station synchronizes the data on the network side to the local database, and when it detects that the communication link with the core network is interrupted, enters the fault weakening mode, and determines whether the base station is supported in the fault weakening mode according to the data in the local database. When the terminal requests the service, when the service requested by the terminal is supported, the service is managed to maintain the connection state; when the service requested by the terminal is not supported, the terminal enters the sleep mode. When the base station is switched from the normal mode to the fault weakening mode, the related services supported by the base station are maintained, so as to maintain the continuity of the service as much as possible. Since the base station works in the fault weakening mode, the terminal does not need to be re-registered and authenticated. The signaling overhead can be saved and the situation that some terminals cannot access the base station due to the access storm can be avoided, the service processing efficiency is improved, and the user experience is improved.
