Description
Technical Field
The embodiment of the application relates to the field of communication, and in particular relates to an information configuration method and related equipment.
Background
The message sequence number information belongs to the related configuration of a radio bearer (DRB) between a base station and a terminal, and includes the message sequence number information of a Packet Data Convergence Protocol (PDCP) and the message sequence number information of a Radio Link Control (RLC). In the process of communication between the terminal and the base station, it is necessary to ensure that the message sequence number information configured on the terminal side is consistent with the message sequence number information configured on the cell side, otherwise, an anomaly of the communication service may be caused.
In the prior art, if a terminal needs to perform inter-cell handover, a base station sends message serial number information configured by a cell to which the terminal needs to be handed over to the terminal, after the terminal receives the message serial number information, the message serial number information needs to be configured locally, so that the message serial number information is consistent with the message serial number information configured by the cell, a handover completion message is sent to the base station after the configuration of the message serial number information is completed, if the terminal fails to complete the configuration of the message serial number information, the terminal does not send the handover completion message to the base station, that is, if the terminal fails to reconfigure the message serial number information, the terminal initiates reconstruction to the base station, so that communication service is continuously performed.
However, the terminal may be re-established to any cell, and therefore, the message sequence number information configured by the terminal side may not be consistent with the message sequence number information configured by the cell side, which may cause an exception to a subsequent communication service.

If the base station determines that the terminal reconfigures the message serial number information fails and receives a reestablishment request message from the terminal, the reestablishment request message is sent by the terminal to a first cell of the base station, the reestablishment request message is used for indicating that the terminal requests to reestablish to the first cell, after the base station receives the reestablishment request message from the terminal, in order to ensure that the message serial number information configured by the terminal is consistent with the message serial number information configured by the first cell, first message serial number information can be sent to the terminal, the first message serial number information is consistent with the first message serial number information configured by the first cell, after the terminal receives the first message serial number information, the first message serial number information can be configured locally, after the terminal configures the first message serial number information, the base station can receive a first handover completion message or a first reconfiguration completion message from the terminal, and the first handover completion message or the first reconfiguration completion message is used for indicating that the terminal has configured the first message serial number information.
In the embodiment of the application, after the terminal is failed to reconfigure and initiates reconstruction to the first cell, the base station sends the first message serial number information to the terminal, so that the terminal configures the first message serial number information, thereby ensuring that the first message serial number information configured by the terminal is consistent with the message serial number information configured by the first cell, and ensuring normal development of communication services.
In a possible implementation manner, the failure of the terminal to reconfigure the message serial number information may specifically be that the base station sends, to the terminal, second message serial number information, where the second message serial number information is used for the terminal to locally configure second message serial number information, the second message serial number information is consistent with message serial number information configured in a second cell, the second message serial number information is used for establishing a connection between the terminal and the second cell, and the base station includes the second cell. After the terminal completes the configuration of the second message sequence number information, the terminal may send a second handover complete message or a second reconfiguration complete message to the base station, and if the base station does not receive the second handover complete message or the second reconfiguration complete message from the terminal within a preset time duration, the base station may determine that the terminal has failed to reconfigure the message sequence number information.
In a possible implementation manner, the base station may send the first message sequence number information to the terminal through a handover command or a reconfiguration message.
In the embodiment of the application, the form of sending the first message serial number information to the terminal by the base station is limited, and the realizability of the scheme is improved.
In a possible implementation manner, after the base station sends the first packet serial number information to the terminal, if the base station does not receive the first handover complete message or the first reconfiguration complete message from the terminal within a preset time duration, the base station will continue to send the first packet serial number information to the terminal until the first handover complete message or the first reconfiguration complete message from the terminal is received.
In the embodiment of the application, the base station can send the first message serial number information to the terminal for multiple times, so that the terminal can be ensured to complete the configuration of the first message serial number information successfully.
