A method for controlling handover using a Relay Station (RS) whose coverage includes at least one mobile station is provided. In the method, the RS monitors an uplink band allocated to a mobile station and obtains a Connection ID (CID) and a Medium Access Control (MAC) address of the mobile station. The RS transmits a scanning request message including the MAC address of the mobile station to a base station. The RS then receives a scanning response message including scanning timing and scanning interval information from the base station and scans neighbor base stations using the information included in the scanning response message. This method more efficiently performs handover of mobile stations in the RS coverage.

L'invention concerne un procédé de contrôle de transfert au moyen d'une station relais (RS), dont la couverture comprend au moins une station mobile. Dans ce procédé, la station relais (RS) surveille une bande de liaison montante attribuée à une station mobile et obtient une identification de connexion (CID) et une adresse de contrôle d'accès au support (MAC) de la station mobile. La station relais (RS) transmet à une station de base un message de demande de scannage comportant l'adresse MAC de la station mobile. Ladite station relais (RS) reçoit, ensuite, un message de réponse de scannage contenant des informations de synchronisation et d'intervalle de scannage en provenance de la station de base et scanne des stations de base voisines, au moyen des informations contenues dans le message de réponse de scannage. Ce procédé permet d'effectuer plus efficacement le transfert de stations mobiles dans la couverture d'une station relais.
