なると共に高価なものとなる欠点があつた。 There are various types of mobile radio communication systems depending on the purpose, such as the pager system, which only calls a mobile terminal, and the car phone system, which mutually occupies a communication channel and makes calls in the same way as a regular telephone. ing. In the former pager system, the mobile terminal simply receives a paging signal from the base station and displays an incoming call; it is only a one-way call, and it does not have an incoming call display response function. It was not possible to identify whether the mobile terminal received the paging signal or not. In addition, the latter car phone system allows calls and calls from the mobile terminal, but since it occupies the communication channel, it is necessary to prepare many communication channels, and correspondingly, the mobile terminal has a large number of communication channels. Since it must be equipped with a frequency selection function and a transmission function, it has the drawback of becoming complicated and expensive.

A verification circuit 7 verifies whether the mobile terminal is authorized to make a call or a mobile terminal belonging to a group, and upon verification, the received message is sent from the terminal 2 to the general subscriber and sent to the next mobile terminal. A call permission signal 37 is sent to the terminal or group. If the verification does not match, the received message is invalidated and the previous call permission signal is sent again. If there is no response to the call permission signal within a predetermined time, a call permission signal for the next group is sent.
