Method and device for supporting group handover

摘要

The method and the device for supporting group handover are disclosed. The method supporting group handover is provided, which is applied to UE in communication with network via a RN, including: a base station S-DeNB switching RN to a base station T-DeNB; and said S-DeNB switching UE served by said RN to said T-DeNB; wherein the MME serving said RN and the MME serving UE served by said RN are the same. Another embodiment of the present invention further provides a base station supporting group handover, The technical scheme set forth in the present invention can reduce unnecessary signaling procedure, the possibility of network congestion, and can reduce the signaling procedure of handover when group handover occurs, so as to reduce the failure of the handover process and ensure the continuity of service.

1. A method of supporting group handover, the method comprising:
receiving, by a serving base station from a relay node (RN), an uplink message for a network attachment or a location update of an user equipment (UE) served by the RN; selecting, by the serving base station, a mobility management entity (MME) for the UE served by the RN as the RN; determining, by the serving base station, a handover for the RN and the UE; switching, by the serving base station, the RN serving the UE in communication with a network from the serving base station to a target base station; and switching, by the serving base station, the UE served by the RN to the target base station.
