A user equipment handover method and a base station, which relate to communication technologies. When a target base station determines that a UE needs to be handed over from a source base station to a target base station, and needs to perform handover between a unicast bearer and a multicast/multicast bearer, due to the data in the target bearer The progress of packet sending may be less than the progress of sending data packets in the original bearer, so the target base station receives data packets sent by the original bearer and the target bearer at the same time. When the progress of receiving the data packet is in the middle, the UE is switched to the target bearer, thereby improving the service continuity during the UE switching process.
