CONSTITUTION:The cordless telephone sets 15-18 and the master station radio devices 51-5n, 61-6n, 71-7n have different subscriber numbers from each other. When the telephone set 15 designating the master station radio device 71 connected to an exchange station 1n as a home area moves from a service area 121 of the device 71 to a service area 10n of the device 5n belonging to an exchange station 11, the telephone set 15 receives an outging frequency f3 of the area 10n and stops automatically. The stopped telephone set 15 irradiates an incoming frequency f4 and transmits the subscriber number of the telephone set 15 to the exchange 11 automatically. This number is received at the device 5n and transmitted to the exchange station 11. When this number is decoded at the station 11, the location of the telephone set 15 is transmitted to the station 1n. This information is stored in the station 1n and the totalizatin of charging to the transfer of an incoming call or its transmission is done.
