Also in this embodiment, even when the call information (message) is different, the signal transmission and reception between the exchange 72 and the radio base station 73 can be realized at once by using the continuous display. This has the effect of reducing the number of signals between the radio base stations 73.

Although the above description has been made between one switching center and a radio base station, the present invention provides, as shown in FIG. 8, one switching center via another switching center. The present invention can be applied even when reaching a wireless base station.

By adopting such a configuration, for example, a subscriber in Tokyo can receive a distribution service even during a business trip to Osaka, which is out of the service area. In other words, by registering with the exchange 82 in Tokyo when a business trip is made, a call to the subscriber is transferred from the exchange 82 to the exchange 86 in Osaka. The exchange 86 sets the radio base station 8 in accordance with the index.
7 and the business traveler receives the distribution service as one of the subscribers 88.

[0031]

According to the present invention, a signal transmitted and received between the exchange and the radio base station is configured to have a radio address corresponding to the number of subscribers to which the distribution is made. Has the effect that transmission and reception can be performed at once.

This effect is remarkably high in broadcast distribution in which the same message is distributed to a plurality of subscribers, since only one message needs to be included in the signal between the exchange and the radio base station. .
