When the information is received by the wireless multimedia terminal device 6, registration as an information provision target terminal is performed in advance, or the information element in the call setting message is used for each call setting request. To send an information provision request message.

When the call setting is requested from the wireless multimedia terminal device 6, the base station control unit 42 executes a process for call setting according to a well-known procedure. Such a mode setting process is executed.

In this mode setting processing, the base station control unit 42 first determines whether or not information provision is requested from the wireless multimedia terminal device 6 which has requested call setting, or whether the wireless multimedia terminal which has requested call setting has It is determined whether or not the device 6 is registered as an information provision target terminal (step ST1 and step ST2).

Here, the information provision request message is not indicated in the information element in the call setup message, and the wireless multimedia terminal device 6 that has issued the call setup request is not registered in the information provision target terminal table. If so, there is no need to provide information to the wireless multimedia terminal device 6 that has issued the current call setting request, so the base station control unit 42 sets the normal mode in which no information is provided.

On the other hand, an information provision request message is indicated in the information element in the call setup message, or the wireless multimedia terminal 6
If is registered in the information provision target terminal table,
The base station control unit 42 determines whether the information provision mode is a multiplex system or a combining system (step ST4).
