Abstract
Through a technique such as a carrier sense system or the like, a mobile station (14) identifies a base station (12) (requested base station) by which the mobile station is to be controlled. In response to polling from a key station (10), the base station informs the key station (10) of the requested base station. When the key station (10) performs the polling to know that a receiving base station which obtained the response is different from the requested base station, the next polling will be made through both the base stations (12). If the key station receives the response from the requested base station, the key station switches the base station controlled by itself from one to another.
