Abstract

Embodiments of the present application provide a method of handover in device to device communication, a base station and a communication system. The method of handover includes: transmitting, by a source base station, a handover request for handing over UE, the handover request comprising information indicating the UE to perform D2D communication with paired UE; receiving a response of the handover request transmitted by one or more base stations, and selecting one of the base stations as a target base station; and handing over the UE to the target base station according to the response of the handover request transmitted the target base station. With the embodiments of the present application, the UE and the paired UE may be made to proceed with performing D2D communication in the target base station, thereby further saving signaling overhead, and reducing waste of resources.
