Method and device for cluster UE switching, cluster UE, and network side device

The invention discloses a method and a device for cluster UE (user equipment) switching, a cluster UE, and a network side device, used to solve a problem that UE in a cluster system can be switched over at any time when moving in a community, and a present business process is not interrupted. The method for cluster UE switching comprises: measuring signal quality of a present community and signal quality of a neighbor community; determining whether the signal quality of the present community and the signal quality of the neighbor community satisfy a preset judgement regulation, and obtaining a judging result; and when the judging result is that both of the signal quality of the present community and the signal quality of the neighbor community satisfy the preset judgement regulation, controlling the present community to switch to the neighbor community so that the cluster UE continue with the service proceeded in the present community. Using the technical scheme, mobile management of the cluster UE in the cluster system based on TD standards is achieved, and the cluster UE switches when moving in a community and the present service is not interrupted.
