In a conventional system, there is a possibility that human errors are generated in setting registration information because a maintenance engineer manually enters registration information into a session reference network controller which integrally controls access terminals and base stations. To improve the system, a session reference network controller (102) stores the number of access terminals (100), N, in advance. And, when a "base distance" setting request is received from an access terminal (100) via a base station (101), the session reference network controller (102) or an OAM (Operation, Administration and Maintenance) server (103) determines a base station, which is one of a plurality of controlled base stations (101) and is Nth nearest from the base station that has transmitted the setting request, and sets the distance between the base station (101), which has transmitted the setting request, and the base station (101), which is Nth nearest, as the "base distance".
