<p>At an inter-base station handover of a mobile relay node, to avoid duplication of identification information of relay nodes and continue communication by a mobile station under control of the relay node, it is determined whether a situation where a plurality of relay nodes having the same identification information exist in a service area of one base station occurs before the mobile relay node moves from one base station to another and makes an inter-base station handover and, in the case where the duplication occurs, when changing identification information of a relay node so as to differentiate each identification information, a handover of a mobile station communicating with a relay node whose identification information is to be changed in a service area of the relay node is made from the relay node to a base station to thereby continue a service for the mobile station by the base station, and, after the identification information of the relay node is changed, a handover of the mobile station having been communicating with the relay node in the service area is made from the base station to the relay node to thereby restart a service by the relay node.</p> |
