Abstract

A mobile exchange office stores an identifier of a base station corresponding to an identifier of each mobile terminal. The base station stores identifiers of base stations corresponding to an identifier of a mobile terminal except for own identifiers. Receiving a call signal for a mobile terminal, the mobile exchange office searches an identifier of a base station corresponding to the mobile terminal based on this call signal and sends a call signal to a base station in accordance with this searched identifier. The base station determines a sender of the call signal. If the sender is a mobile exchange office, the base station transfers the call signal to another base station corresponding to a stored identifier and calls the mobile terminal in own radio zone. If the sender is a base station, it calls the mobile terminal in own radio zone.
