USER EQUIPMENT HANDOVER METHOD, AND BASE STATION

摘要

Embodiments of the present invention provide a method. When a target base station determines that the UE needs to be handed over from a source base station to a target base station and needs to perform a handover between a unicast bearer and a multicast/multicast bearer; because a progress of sending a data packet by using a target bearer may be slower than a progress of sending a data packet by using an original bearer, the target base station receives a data packet sent by using the original bearer and a data packet sent by using the target bearer, and when it is determined that a progress of receiving the data packet is faster than or equal to a progress of receiving the data packet by the target base station by using the target bearer, the target base station hands over the UE to the target bearer.

1. A user equipment handover method, comprising:
determining, by a target base station, that user equipment (UE) needs to be handed over from a source base station to the target base station and needs to perform a handover between a unicast bearer and a multicast/multicast bearer; receiving, by the target base station, a data packet sent by using the unicast bearer and a data packet sent by using the multicast/multicast bearer; and when the target base station determines, according to a synchronization protocol data packet identifier of the data packet, that a progress of receiving a data packet by the target base station by using an original bearer is faster than or equal to a progress of receiving a data packet by the target base station by using a target bearer, handing over, by the target base station, the UE to the target bearer.
