Abstract
Embodiments of the present application relate to the technical field of wireless telecommunications, and disclose a method and device for triggering a handover and transferring mobility management entity (MME) pool identification information. The present application solves the problem of transferring UE context information to the MME pool to which a target donor eNB (DeNB) belongs after a relay node (RN) changes DeNB. In the present application, after an RN switches from a source DeNB to a target DeNB, the RN, according to the acquired identification information of the MME pool to which the target DeNB belongs, determines whether the target DeNB and the source DeNB belong to the same MME pool; if the determination is negative, the RN transmits a handover request to the MME of a UE connecting to the RN, the handover request carrying the RN identifier as the target identifier. The present application enables the transfer of UE context to the MME pool to which the target DeNB belongs.
