technical field

The present disclosure relates to the communication field, and in particular, to a handover control method and device, and a storage medium.

Background technique

At present, the base station can send a RRC (Radio Resource Control, radio resource control) Release (release) message to the terminal in the connected state, so that the terminal enters the unconnected state. Among them, after receiving the RRC Release message, the terminal can delay for a period of time before entering the non-connected state, so as to ensure that the terminal has enough time to send the feedback information that the RRC Release message is successfully received, so that the base station can confirm that the terminal has successfully received the RRC Release message, so that the base station releases the context of the terminal, and avoids the problem of inconsistency between the base station and the terminal regarding the state of the terminal.

In addition, CHO (Conditional HandOver, conditional handover) is proposed in 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology). During the delay period after the terminal receives the RRC Release message, the terminal will continue to evaluate the CHO handover conditions, which may trigger the terminal to perform cell handover, that is, trigger the reconfiguration with sync (synchronous reconfiguration) process. However, before the terminal completes the synchronous reconfiguration process, the base station side may have released the context of the terminal, causing the synchronous reconfiguration process to fail.

In related technologies, after the terminal receives the RRC Release message, it can delay for a period of time before entering the non-connected state. The terminal will perform normal radio resource management and wireless link monitoring during the delay period. After the delay period, even if the base station does not receive Feedback information to the terminal may also release the context of the terminal.

In order to improve the robustness of cell handover, 5G proposes CHO. The network side can configure the configuration information corresponding to the conditional reconfiguration for the terminal in advance, and the terminal performs RRM (Radio Resource Management, radio resource management) measurement by itself. Synchronous reconfiguration is performed.

Considering that the terminal will continue to evaluate the CHO handover condition within the delay period after receiving the RRC Release message, it may trigger the synchronous reconfiguration process. However, before the terminal completes the synchronous reconfiguration process, the base station may have released the context of the terminal, resulting in failure of the terminal synchronous reconfiguration process.

In order to solve the above technical problem, the present application may adopt but not limited to any of the following methods to avoid failure of the synchronization reconfiguration process within the delay period after the terminal receives the RRC release message.

Alternatively, condExecutionCond may be that the distance between the terminal and the reference point is greater or smaller than a preset distance value, or the change amount of the distance value exceeds a preset distance threshold. Alternatively, condExecutionCond can refer to the point in time when synchronous reconfiguration takes place.

In the embodiment of the present disclosure, the terminal may stop the conditional reconfiguration process by stopping the terminal from evaluating the configured reconfiguration conditions for synchronous reconfiguration.
