ABSTRACT:
In a system for reducing congestion of a radio paging channel, a radio base station has a radio paging channel for connection with a radio telephone. A first announcement section makes reception announcement for requesting a calling number and a called number to a calling subscriber in response to an incoming call for a call-back automatic announcement service from the calling subscriber. A registering section registers the calling and called numbers informed from the calling subscriber. A monitoring section monitors congestion of the radio paging channel of the radio base station, and outputs a detection signal when a usage of the radio paging channel becomes lower than a preset level. An outgoing call control section generates an outgoing call to a called subscriber in response to the detection signal from the monitoring section on the basis of the called number registered in the registering section. A second announcement section converts the calling number registered in the registering section into speech to make call-back announcement to the called subscriber when the called subscriber responds to the call from the outgoing call control section. A switching section selectively performs connection control among the calling subscriber, the called subscriber, and the respective section.
