Patent ID: 8781477

Claim:
A handover method in a relay network, comprising: receiving, by a relay node, an evolved universal terrestrial radio access network cell global identifier (ECGI) allocated by an operation administration and maintenance (OAM), wherein the ECGI is used to identify the relay node and includes an identifier of a control base station controlling the relay node; broadcasting, by the relay node, the ECGI to a terminal in the coverage area of the relay node through a system information broadcast message; obtaining, by a base station, the identifier of the control base station from the ECGI after receiving a measurement report carrying the ECGI sent by the terminal; creating, by the base station, a handover required message carrying the identifier of the control base station obtained by the base station from the ECGI; sending, by the base station, the handover required message to a mobility management entity (MME) so that the MME sends a handover request message carrying the ECGI to the control base station according to the identifier of the control base station carried in the handover required message.
