チャネルへの切替えを行うことを特徴とする。A broadcast system of a mobile communication system according to the present invention broadcasts to mobile stations existing within the service area of a base station corresponding to a specific number from a broadcast dedicated terminal. In a broadcast system of a mobile communication system that performs broadcast communication, an exchange sends a notification signal to the base station indicating that a broadcast notification is in progress, and the base station talks when it receives the notification signal. The mobile station in communication transmits a channel switching instruction signal for instructing switching to the broadcast channel, and the mobile station in the call transmits to the broadcast channel when receiving the channel switching instruction signal. The feature is that switching is performed.

報通話を受信する。Transmission of the simultaneous broadcast is carried out by two-digit dialing as a specific number from the simultaneous broadcast exclusive terminal 1. The exchange 3 determines the base station 5 by the two-digit dialed number received via the simultaneous broadcast trunk 2. The exchange 3 captures the voice channel trunk 4 corresponding to the base station 5 and sends the broadcast-only order to the base station 5.
When the base station 5 receives the order, the base station 5
Broadcast notification is sent to mobile stations existing in the service area. Here, it is assumed that the mobile station 6 is not in a call and the mobile station 7 is in a call. The exchange 3 sends a broadcast notification signal on the communication channel of the mobile station 7 via the base station 5 to notify that the broadcast notification is in progress. The mobile station 7, which has been informed that the broadcast notification is being performed on the call channel, informs the subscriber of the call partner that the broadcast notification is being given.
For example, a warning lamp or warning sound is displayed. When this display causes the calling party subscriber to press the broadcast interrupt key, the mobile station 7 sends a channel switching request signal to the base station 5 to switch to the broadcast channel. Receiving this channel switching request signal, the base station 5 returns a channel switching instruction signal to the broadcast communication channel to the mobile station 7, and the mobile station 7 tunes to the broadcast communication channel and broadcasts it. Receive a call.
