PURPOSE:To execute an incoming to a subscriber concerned even when the receiving position of a subscriber terminal is not clear in a station side at the moving time of the subscriber terminal by providing simultaneous calling function to simultaneously send address information to the subscriber whose connecting destination is not clear. CONSTITUTION:When a subscriber 12 executes the incoming call to a subscriber 10, the calling of the subscriber is inputted through a subscriber circuit 32 to a time-dividing route 40. Thus, an address information sending circuit 50 sends the address information, however, when the connecting destination is not specified for the subscriber 10, the address information are sent to all terminals. The subscribers 10 and 11 always supervise the address information and when the address information are sent, the information are received and identified. In case of the incoming call to itself, a responding message is returned to the address information sending circuit 50. In the station side, the reception of the subscriber 10 is known by this message and the incoming call is executed to the subscriber 10 by the subscriber 12.
