There is provided a handover method by a mobile relay station (MRS) or base station (BS) so as to effectively perform a handover of the MRS and mobile stations (MSs) in an environment in which data is communicated through a relay of the MRS. There is also provided a handover method capable of securing backward compatibility of an MS during a handover. There is provided a handover method in which an MRS is considered. It is possible to improve the efficiency of the handover by allowing handovers of the MRS and MSs to which the MRS relays to be initiated by the MRS or BS. It is possible to secure the backward compatibility of the MSs by allowing the MRS to generate and manage a mapping relation between information on communication identifiers (CIDs) of the MSs, which are changed during the handover, and information on previous CIDs of the MSs. |
