２１へ通知する（Ｓ6 ）。In the communication control device 11, as shown in FIG. 5B, a communication control unit transmits and receives a signal for terminating connection with a base station via an interface unit 22, a timer control unit 23, an authentication unit 24, and a state management unit. It transmits and receives signals to and from the unit 25. FIG. 6 shows a processing procedure of the communication control device 11. When an incoming call arrives from the network side, first, the state management unit 25 is set to an incoming call permitted state (S 1 ), and a mobile station for the incoming call issues an incoming request signal to each base station in the zone where the mobile station is registered. And issues a timer setting request to the timer control unit 23 (S 2 ), waits for an incoming response signal (S 3 ), and when the incoming response signal is received, inquires the status management unit 25 of the status (S 2 ).
4 ). The state management unit 25 checks whether or not the incoming call is permitted (S 5 ). If the incoming call is in the acceptable state, the state is notified to the communication control unit 21 (S 6 ).

5 is set to a call non-permission state, and an authentication request signal is sent to the base station that sent the call response signal (S 7 ). After that, the authentication unit 24 checks the authentication response signal received from the mobile station (S 8 ). If there is a notification from the authentication section 24 that a correct authentication result has been obtained (S 9 ), the base station and the communication control device 11 are connected (S 10 ), and a communication between the calling side and the mobile station is performed. A call is made. When the call ends (S

Returning to step 2 , the incoming request signal is transmitted again, and the process ends if the second time-out occurs. Also if not called permissive at step S 5 the state management unit 25 notifies the incoming call is a non-permissive to the communication control section 21 (S 15), the communication control unit 21 receiving this line disconnection processing carried out (S 12).

に同一符号を付けてある。According to the third and fourth embodiments of the present invention, a valid mobile station and an unauthorized mobile station are provided in a timer that enables the communication control device to receive an incoming response signal from the mobile station in response to the first incoming request signal. A case will be described with reference to FIG. 4 where a response cannot be made and the incoming call processing is terminated unless a response is made even within the second timer. Also in this case, parts corresponding to those in FIGS.

A signal 32 requesting the setting of the timer 31 is transmitted. Base stations 12 and 13 are mobile stations 1
The incoming request signals 33 and 35 are transmitted to the terminals 4 and 15, respectively.
However, the timer 31 expires before the incoming response signal is received, and the timer control unit 23 that detects this expires.
Transmits a retransmission request signal 53 of an incoming request signal to the communication control unit 21 and sets a timer 54 that starts for a predetermined time. The communication control unit 21 transmits the incoming request signal 55 to the base station 1
2 and 13, and the base stations 12 and 13 transmit incoming request signals 56 and 57 to the mobile stations 14 and 15. However, the timer 54 expires before the incoming response signal is received, and the incoming process ends.

動局として選択できる利点がある。As described above, according to the prior art, when a call response signal from a mobile station is first received, the mobile station that has transmitted the call response is selected as a call receiving non-permission state as a call receiving mobile station. If the legitimate mobile station sends the incoming response signal but it is later in time than the incoming response of the unauthorized mobile station, the legitimate mobile station is not selected as the terminating mobile station and the call is not allowed. Therefore, retransmission of the incoming request signal is not performed. However, in the present invention, the incoming call is not permitted when the valid mobile station is confirmed by authentication. Therefore, even if the incoming response of the valid mobile station is later than the unauthorized mobile station, the incoming call is not received. A response signal can be accepted, and in the second and third aspects of the invention, it is also possible to retransmit an incoming request signal when a predetermined time in the incoming call permitted state has expired, so that only a legitimate mobile station can be selected as an incoming mobile station. There are advantages.
