Abstract
Disclosed in the present application are a method and a device for intra-cell handover, and a method and a device for path switching, used for avoiding network side and user equipment (UE) side next hop chaining counter (NCC) desychronization when a UE switches out of a relay node (RN), so as to avoid communication failure. The method for intra-cell handover provided in the present application comprises: an RN determining whether the value of the difference between the UE side NCC and the NCC most recently received by the RN and allocated for the UE by a mobility management entity (MME) serving the UE meets the preset triggering requirement for intra-cell handover; if the value of the difference meets the triggering requirement, then the RN initiates intra-cell handover.
