<p>A mobile exchange office(1) stores an identifier of a base station(BS2) corresponding to an identifier of each mobile terminal(4). The base station(BS2) stores identifiers of base stations(BS1, BS3) corresponding to an identifier of a mobile terminal(4) except for own identifiers. Receiving a call signal for a mobile terminal(4), the mobile exchange office(1) searches an identifier of a base station(BS2) corresponding to the mobile terminal(4) based on this call signal and sends a call signal to a base station(BS2) in accordance with this searched identifier. The base station(BS2) determines a sender of the call signal. If the sender is a mobile exchange office(1), the base station(BS2) transfers the call signal to another base station(BS1, BS3) corresponding to a stored identifier and calls the mobile terminal(4) in own radio zone(52). If the sender is a base station, it calls the mobile terminal(4) in own radio zone(51, 53). <IMAGE></p> |
