3).

The PID / DN management unit 806 knows that there is no registration of the incoming communication terminal corresponding to the dialed personal identification number PID2 (B4 in FIG. 13), and sends a position non-registration notification to the terminal management unit 805. (604). Terminal management unit 8
05 requests the user management unit 807 to connect to the talkie for the outgoing call (605). The user management unit 807 generates a call state of the call number # 2 for the personal identification numbers PID4 and PID2, and sets the state of the call state storage area to “outgoing” (C1 in FIG. 13).
0). Further, the release reason “5” of the user 2 having the personal identification number of PID2 is read, and the talker 803 in the exchange device 801 corresponding to the release reason is instructed (606). At the same time, the call state is changed to "communicating" (C1 in FIG. 13).
0 → C11 in FIG. 13), respond to the calling user 4.

As described above, in the fifth invention, the incoming user 2
Registers the reason for canceling the location registration cancellation, and subsequently the calling user 4 for the called user 2 is connected to the talkie 803 in the switching device 801 corresponding to the cancellation reason. Can respond.

[0046]

As described above, according to the present invention,
Even when introducing personal communication that allows outgoing calls using personal identification numbers, there is no need to prepare individual terminals,
Not only can terminal equipment costs be reduced,
Flexible network configuration can be realized, and even if network configuration changes such as increase or decrease of terminals, no change of control device is required.
It greatly contributes to the ease of operation of personal communication services.
