1. A method for Mobile Station (MS) handover, the method comprising:
- sending, by a serving Multi-hop Relay Base Station (MR-BS), service information of a MS and service information of a Relay Station (RS) to the RS;
receiving, by the serving MR-BS, handover-assisting information from the RS served by the serving MR-BS, wherein the handover-assisting information comprises association information of the MS, wherein the association information being Uplink Physical Layer (UL PHY) quality information of the MS, wherein the handover-assisting information further comprises a result of judgment by the RS about whether the RS is suitable for being a target station of the MS, and the result of the judgment about whether the RS is suitable for being the target station of the MS is made by the RS according to the service information of the MS and the service information of the RS sent by the serving MR-BS; and
determining, by the serving MR-BS, whether to recommend the RS to the MS as a target station according to the handover-assisting information.

Abstract
A method, system and device for MS handover are provided in an embodiment of the present invention. The method includes: receiving the handover-assisting information from the RS by the serving MR-BS; determining whether to recommend the RS to the MS as the target station according to the handover-assisting information by the serving MR-BS. The embodiments of the present invention enable the serving MR-BS to obtain related information from the RS and the serving MR-BS of the MS to better ascertain the potential target station and related information to be recommended to the MS. This helps improve the handover performance of the MS and reduce the failure rate.
