RADIO BASE STATION SELECTION METHOD

摘要

PROBLEM TO BE SOLVED: To utilize a packet transfer protocol between a home network and a remote network and to continue communication by selecting a remote network base station to satisfy a required quality when a home network base station to satisfy the required quality is not present. SOLUTION: A base station cyclically transmits its own base station ID and a domain ID by means of reporting signals. A radio LAN terminal receives the reporting signals of peripheral base stations for a fixed period and prepares a list of base stations to satisfy a required quality (S-1). In the case a home base station is present inside the base station list (Y of S2-2), the home base station of best quality is selected (S2-3). When a home base station is not present (N of S2-2), the remote base station of the best quality of is selected (S2-4 and S2-5). If the base station to satisfy the required quality is not present (N of S2-4), it is judged as the outside of a service area (S2-6).
