Description

Switching control method and device and storage medium

Technical Field

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

Background

Currently, the base station may put the terminal into the non-connected state by transmitting an RRC (Radio Resource Control ) Release message to the terminal in the connected state. After receiving the RRC Release message, the terminal may delay a period of time to enter a non-connection state, so as to ensure that the terminal has enough time to send feedback information successfully received by the RRC Release message, so that the base station side may confirm that the terminal has successfully received the RRC Release message, so that the base station releases the context of the terminal, and avoid a problem that the state of the base station and the terminal for the terminal are inconsistent.

Further, CHO (Conditional HandOver, condition-based handover) is proposed in 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology). During the delay period after the terminal receives the RRC Release message, the terminal may still continue to evaluate CHO handover conditions, and may trigger the terminal to perform cell handover, i.e., trigger reconfiguration with sync (synchronous reconfiguration) procedure. But before the terminal completes the synchronization reconfiguration process, the base station side may have released the context of the terminal, resulting in failure of the synchronization reconfiguration process.

In the related art, after receiving the RRC Release message, the terminal may delay for a period of time and then enter the non-connected state, and the terminal may perform normal radio resource management and radio link monitoring during the delay period, and after the delay period, the base station may Release the context of the terminal even if the feedback information of the terminal is not received.

In order to improve robustness of cell handover, CHO is proposed in 5G, where a network side may configure configuration information corresponding to a condition reconfiguration for a terminal in advance, and the terminal performs RRM (Radio Resource Management ) measurement itself, and performs synchronous reconfiguration when the reconfiguration condition is satisfied.

Considering that the terminal still continues CHO handover condition evaluation within a delay period after receiving the RRC Release message, a synchronization reconfiguration procedure may be triggered. But before the terminal completes the synchronization reconfiguration process, the base station side may have released the context of the terminal, resulting in failure of the synchronization reconfiguration process of the terminal.

In order to solve the above technical problem, the present application may avoid the failure of the synchronization reconfiguration procedure in any one of the following manners within a delay period after the terminal receives the RRC release message.

In the first way, after receiving the RRC release message, the terminal stops the condition reconfiguration process and the corresponding synchronous reconfiguration process.

An embodiment of the present disclosure provides a handover control method, referring to fig. 1, and fig. 1 is a flowchart of a handover control method according to an embodiment, where the handover control method may be applied to a terminal, and the method may include the following steps:

in step 101, a radio resource control RRC release message sent by a base station is received.

In step 102, the condition reconfiguration process and the corresponding synchronous reconfiguration process are stopped for a delay period.

In the embodiment of the present disclosure, the delay period is a period in which the terminal delays entering a non-connected state after receiving the RRC release message. The duration of the delay period may be 60 milliseconds, and the unconnected state includes, but is not limited to, an idle state or an inactive state. The terminal may stop the condition reconfiguration process and the synchronous reconfiguration process corresponding to the condition reconfiguration during the delay period.

In the above embodiment, after receiving the RRC release message sent by the base station, the terminal may stop the condition reconfiguration process and the corresponding synchronous reconfiguration process in the delay period, so as to achieve the purpose of avoiding failure of the synchronous reconfiguration process in the delay period after the terminal receives the RRC release message, and the availability is high.

In some alternative embodiments, the terminal stops the condition reconfiguration process, including but not limited to at least one of:

in the first case, the radio resource management RRM measurement of the terminal is stopped.

In the embodiment of the disclosure, the terminal may stop the condition reconfiguration process in a manner of stopping RRM measurement during the delay period.

And in the second case, stopping the terminal from evaluating the configured reconfiguration conditions for synchronous reconfiguration.

In one possible implementation, the evaluation of the configured reconfiguration conditions for the synchronous reconfiguration by the terminal may be stopped by stopping the evaluation of the configured configuration information corresponding to the conditional reconfiguration by the terminal.

The configuration information corresponding to the condition reconfiguration comprises the reconfiguration condition and configuration information of synchronous reconfiguration when the reconfiguration condition is met by the terminal.

In the embodiment of the present disclosure, the configuration information may be configured for the terminal in advance by the network side, where the terminal side stores the received configuration information corresponding to varconditional reconfig (conditional reconfiguration), and specifically, the configuration information includes a plurality of entries, where each entry includes a condReconfigId-r16 (conditional reconfiguration identifier, specified in version 16), a condexeclioncond-r 16 (reconfiguration condition, specified in version 16), and a condrrcrreconfig-r 16 (configuration information of the target cell, specified in version 16).

Further, condexecu-nd may include, but is not limited to, at least one of: signal strength of the serving cell and the target cell; a distance value between the terminal and the reference point; time.

Specifically, condexectioncond may be that the signal strength of the serving cell is smaller than the signal strength of the target cell, and the absolute value of the difference between the two signal strengths exceeds a preset signal strength threshold. Alternatively, condexecdioncond may be that the distance value between the terminal and the reference point is greater or less than a preset distance value, or the change amount of the distance value exceeds a preset distance threshold. Alternatively, condexectioncond may refer to a point in time at which a synchronous reconfiguration is performed.

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

And in the third case, deleting the configuration information stored by the terminal and corresponding to the conditional reconfiguration.

Specifically, the configuration information corresponding to the condition reconfiguration includes the reconfiguration condition and configuration information of the terminal performing synchronous reconfiguration when the reconfiguration condition is satisfied. The specific information content of the configuration information is similar to that of the configuration information mentioned in the above embodiment, and will not be described here again.

In one possible implementation, the entry for performing the synchronous reconfiguration is deleted in the configuration information corresponding to the conditional reconfiguration. I.e. the terminal may stop the condition reconfiguration procedure by deleting all entries for inter-synchronization reconfiguration in the varconditional reconfiguration.

Fourth, deleting at least one of the handover condition and the handover command stored by the terminal.

The switching command is used for indicating the terminal to perform the synchronous reconfiguration when the reconfiguration condition is met. The terminal may stop the condition reconfiguration process by deleting at least one of the stored handover conditions and handover commands.

And in a fifth case, controlling the terminal not to trigger a synchronous reconfiguration process corresponding to the reconfiguration condition when the reconfiguration condition is met.

In the embodiment of the disclosure, the terminal may stop the condition reconfiguration process in a manner that the terminal does not trigger the synchronous reconfiguration process corresponding to the reconfiguration condition when the reconfiguration condition is satisfied.

The foregoing is merely exemplary, and any implementation manner capable of stopping the condition reconfiguration process and the corresponding synchronous reconfiguration process in practical applications shall fall within the protection scope of the present disclosure.

In the above embodiment, the terminal may stop the condition reconfiguration process and the corresponding synchronous reconfiguration process in at least one of multiple manners in the delay period, so as to achieve the purpose of avoiding failure of the synchronous reconfiguration process in the delay period after the terminal receives the RRC release message, and the availability is high.

It should be noted that, in the embodiment of the present disclosure, when determining that the reconfiguration condition for performing the synchronous reconfiguration is satisfied, if the RRC Release message is not received, the terminal may perform the synchronous reconfiguration procedure corresponding to the reconfiguration condition.

In the second way, after receiving the RRC release message, if it is determined that a reconfiguration condition for performing synchronous reconfiguration is satisfied, the terminal may perform a synchronous reconfiguration procedure corresponding to the reconfiguration condition and stop the RRC release procedure.

Wherein the delay period is a period in which the terminal delays entering a non-connection state after receiving the RRC release message. The duration of the delay period may be 60 milliseconds, and the unconnected state includes, but is not limited to, an idle state or an inactive state.

In the above embodiment, after receiving the RRC release message sent by the base station, if it is determined that the reconfiguration condition for performing synchronous reconfiguration is met in the delay period, the terminal may execute the synchronous reconfiguration process corresponding to the reconfiguration condition and stop the RRC release process, so as to avoid a situation that the base station has released the context of the terminal before the synchronous reconfiguration is completed, thereby achieving the purpose of avoiding failure of the synchronous reconfiguration process in the delay period after the terminal receives the RRC release message, and having high availability.

In the embodiment of the present disclosure, in the case that the synchronization reconfiguration process fails, the terminal may store radio link failure information including at least indication information in VarRLF-Report (radio link failure information), where the indication information is used to indicate that the reason why the synchronization reconfiguration process fails is that the terminal receives the RRC release message before performing the synchronization reconfiguration process corresponding to the reconfiguration condition.

In the above embodiment, the terminal may store the radio link failure information including at least the indication information under the condition that the synchronous reconfiguration process fails, record the reason for causing the radio link failure, so that the subsequent network side is convenient to perform network resource optimization based on the radio link failure reason, and the availability is high.
