FIG. 1 shows an embodiment of the present invention.
(A) shows the configuration of the system, and (b) shows a perspective view of the mobile terminal. In the figure, 1 is a normal telephone, 2 and 4 are exchanges, and 31, 32, 33 and 34 are mobile terminals. 341
Is a telephone number transmission button, 342 is a connection mode switch, 343 is a transmission switch, 344 is a response switch, 345 is a channel and sub-channel switch,
Reference numeral 46 denotes a display for displaying a selected channel, a topic of the channel, and the like.

Hereinafter, an example of control for making a wireless call will be described with reference to the sequence diagrams of FIGS. The mobile terminals 31, 32, and 33 have the same function as the mobile terminal.

In FIG. 1, when the user of the mobile terminal 31 sets the connection mode switch 342 to the wireless mode and operates the transmission switch 343, the transmission in the wireless mode is automatically performed, and the exchange 2 receives the transmission. I do. The exchange 2 that has received the notification of attachment is transmitted to the mobile terminal 31. When the user of the mobile terminal 31 receives the acceptance notification, the user of the mobile terminal 31 transmits a wireless calling area identification code to the exchange 2 by dialing or the like.

Upon receiving this identification code, the exchange 2 relays and connects to the exchange 4 corresponding to the calling area. The exchange 4 sends a call notification to the exchange 2. The exchange 2 receives this and transmits a call notification to the mobile terminal 31. Next, when the user of the mobile terminal 31 makes a wireless call, the call is relayed from the exchange 2 to the exchange 4, and from the exchange 4 to the mobile terminals 32, 33, 34, etc. of an unspecified person in the area. Broadcast wireless calls.

A user who wants to communicate in the wireless mode (here, the user having the mobile terminal 32) sets the connection mode changeover switch 342 to the wireless mode and operates the channel switch 345 to switch to the channel. You can hear the corresponding wireless call. The receiver sets the channel switch 342 to the channel to be received and operates the response switch 344. By this response operation, a response signal is automatically sent to the exchange 4. When the exchange 4 receives the response signal, the exchange 4 stops broadcasting the radio call on the channel to which the response has been made, and the mobile terminal 3 that has made the radio call
1 and the mobile terminal 32 are connected.

Next, an example of control when a telephone connection request is made during a call in the wireless mode will be described. In FIG. 1, when the mobile terminal 31 is in a call with the mobile terminal 32 of the communication partner, if there is an incoming call from the ordinary telephone 1, the mobile terminal 31 is notified that there is an incoming call. At the same time, it notifies the mobile terminal 32 that the communication partner has been requested for telephone connection. After receiving this notification, the mobile terminal 31 that is communicating in the wireless mode sets the connection mode switch 342 to the telephone mode and responds by connecting to the caller 1.

The switching center 4 notifies the mobile terminal 32 of a disconnection notice and disconnects the mobile terminal 32. In addition, when the mobile terminal 31 is notified of the incoming call and when the mobile terminal 32 is notified of the request for the telephone connection to the communication partner, the connection between the mobile terminal 31 and the normal telephone 1 is terminated at any of the terminals. When a request for reconnection between the mobile terminals 31 and 32 is made later, the switching center reconnects the mobile terminals 31 and 32 when the communication between the mobile terminal 31 and the telephone 1 is completed.

Next, an example using a specific logical channel will be described. The logical channel here is associated with the physical channel used in actual communication,
A channel that always has a certain meaning. The logical channel has a configuration capable of dealing with a plurality of physical channels.
It is assumed that a certain logical channel is assigned to a topic in a predetermined specific field.

At this time, in FIG. 1, when the mobile terminal 31 requesting communication sets the connection mode changeover switch 342 to the wireless mode and sets the channel switch 345 to a certain logical channel, a topic corresponding to the logical channel is displayed on the display. . Therefore, when the transmission switch 343 is operated, the exchange 2 recognizes that the transmission is for a logical channel, and makes a wireless call using the logical channel.

The mobile terminal that is to receive this communication has 3
If it is 2, the user of the mobile terminal 32 first sets the connection changeover switch 342 to the wireless mode and sets the channel switch 345 to the logical channel of the topic. Next, by operating the sub-channel 345, the communication of the other party (here, the mobile terminal 31) with which communication is desired is selected. Next, when the response switch 344 is operated, the exchange 4 receives the response,
The connection between the mobile terminals 31 and 32 is performed.

Next, a description will be given of an example of control for controlling a radio call area from a network and displaying a call message instead of voice on a mobile terminal to be communicated. The caller 31 registers the radio call area and the call message in advance in the service control station 5 of the network as a service. Here, the radio call area is the area of the exchange 4 and the call message is a message such as “This is... Therefore, when the user of the mobile terminal 31 requests such a service, the switching center 2 which has received the request makes an inquiry to the service control station 5 which controls the network service.

The service control station 5 determines a service from the inquiry information and controls the exchange 2 by executing the service. The exchange 2 connects to the exchange 4 under the direction of the service control station 5. The exchange 4 is a call message "This is .... Please answer somebody."
Is transmitted in a broadcast format.

The user who wants to communicate (here, the mobile terminal 32
When the user operates the mobile terminal to set it in the reception state, a call message is displayed on the display 346 of the mobile terminal 32, so that it can be known that someone is calling.
