Embodiment 1
[0031] In this embodiment, a switching method is provided, figure 1 is a flowchart of a handover method according to an embodiment of the present disclosure, such as figure 1 As shown, the process includes the following steps:
[0032] Step S102, the user equipment UE receives the radio resource control reconfiguration message sent by the source base station, wherein the radio resource control reconfiguration message includes a list of target cells for the UE to perform conditional handover, and each of the list of target cells for conditional handover The information of the target cell includes at least one of the following: frequency point information of the target cell, a physical cell identity of the target cell, a conditional handover command of the target cell generated by the target cell, at least one measurement configuration identification information, and the measurement configuration identification information uses To instruct the UE to perform conditional handover...
Embodiment 1
[0071]In the conditional handover, in order to avoid the failure of sending the measurement report or the handover command, the UE reports the measurement report before the "actual handover condition" is met, that is, when the "pre-handover preparation condition" is met. To achieve this goal, the "preparation condition for handover in advance" is more lenient than the "actual handover condition". For example, taking the configuration of A4 event (the signal quality of the neighboring cell is higher than the threshold) as an example, if the threshold for meeting the "actual handover condition" is Th1 , the threshold for satisfying the "preparation condition for handover in advance" is Th2, and Th2 Figure 6 Prepare a flow diagram for a conditional switch switch, including:
[0072] S410 / S410', the UE reports a measurement report to the source base station when the "advanced handover preparation condition" is met.
[0073] When the base station configures measurement, a frequency...
Embodiment 2
[0082] In the conditional handover, after receiving the conditional handover command (included in the RRCReconfiguration generated by the source cell, as described in step S440 of the first embodiment), the UE does not immediately execute the handover, but continues to stay in the source cell. The target cell in the conditional handover target cell list is measured, and when it is judged that a target cell satisfies the "conditional handover execution condition" of the cell indicated in RRCReconfiguration, the UE performs handover and accesses the target cell. As described in step S440 of the first embodiment, the RRCReconfiguration message generated by the source cell includes identification information for indicating the measurement configuration of the "conditional handover execution condition" of each target cell, such as measID, if the measurement result of a target cell satisfies the Based on the reporting condition of the report configuration (reportConfig) associated wi...
