METHOD AND DEVICE FOR INTRA-CELL HANDOVER

摘要

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.

1. An intra-cell handover method, comprising:
a Relay Node (RN) judging whether the difference between a Next Hop Chaining Counter (NCC) at the User Equipment (UE) side, and an NCC lastly received by the RN, which is allocated to the UE by a serving Mobility Management Entity (MME), satisfies a preset intra-cell handover trigger condition; and the RN initiating an intra-cell handover when the difference satisfies the trigger condition.
