PROBLEM TO BE SOLVED: To allow a portable telephone/automobile telephone system to obtain accurate position information by using position information through a personal handyphone system. SOLUTION: A mobile terminal is configured to receive a communication service through a portable telephone/automobile telephone system and a personal handyphone system. Thus, the mobile terminal receives position information sent from a radio base station of the personal handyphone system and stores the received position information to an HLR connected to the portable telephone/automobile telephone system and the personal handy-phone system. An exchange of the portable telephone/automobile telephone system locates the mobile terminal on the basis of the position information stored in the HLR and assigns a channel to the mobile terminal.
