PURPOSE:To improve the communication service, by integrating an individual number used for telephone service and a telephone number used for radio service, releasing the registration of a telephone terminal at a called party and calling an incoming call until the next registration by means of radio. CONSTITUTION:When a calling subscriber A, for example, dials the individual number of a called subscriber C by a telephone set 20, an information line is set between the telephone set and a PID file 60 via a telephone network 10. When a new telephone set of the subscriber C is registered on the file 60, new telephone set information of the subscriber C is read out from a memory in the file 60 and the telephone set 20 and the new telephone set of the subscriber C are connected with the telephone network 10. When the new telephone set of the subscriber C is not registered in the file 60, whether or not the radio calling with the talkie announcement is done is inquired to the subscriber A, and when the subscriber A is desired, a radio wave is radiated from a radio calling service radio base station 50 to a radio calling receiver 51 of the subscriber C, and the calling signal is transmitted. |
