Abstract
A mobile telephone apparatus operates as follow: when an origination signal is transmitted from the mobile station, the base station of a wireless zone where the mobile station is not present communicates a connection possible signal to the base station in the zone where the mobile station is present, and the base station having a larger number of idle channels than that of the other base station is selected on priority basis independent on the signal intensity. Therefore, when the origination signal from the mobile station is received by a plurality of base stations, the base station having the receiving level larger than the required minimum receiving level and having the maximum number of idle channels is selected, and it is possible to reduce the origination loss rate relative to the conventional system.
