Handover method and system in relay network, relay node, control base station and base station

摘要

Embodiments of the present invention provide a handover method and system in a relay network, a relay node, a control base station and a base station. The method includes: receiving, by a relay node, a first area identifier that identifies the relay node; sending a system information broadcast message carrying the first area identifier to a terminal in a coverage area; receiving a handover request message forwarded by a control base station; and performing, according to the handover request message, a control operation of accessing the relay node on the terminal. The first area identifier that identifies the relay node is allocated to the relay node, so that the terminal in the relay network can be normally handed over from the base station to the relay node.

1. A method for performing handover in a relay network, comprising:
sending, by a control base station, a response message to a relay node according to a received interface setup request message, wherein the response message carries a first area identifier that identifies the relay node; and receiving, by a mobility management entity, a handover required message including target node information from a base station when the relay node is a target of the handover, wherein the target node information includes the first area identifier and an identifier of the control base station, and the identifier of the control base station is obtained according to the first area identifier; sending, by the mobility management entity, a handover request including the first area identifier to the control base station according to the identifier of the control base station included in the handover required message; forwarding, by the control base station, the handover request to the relay node according to the first area identifier in the handover request.
