System for reducing congestion of radio paging channel
First Claim
1. A system for reducing congestion of a radio paging channel, comprising:
- a radio base station having a radio paging channel for connection with a radio subscriber;
mobile switching means for performing a switching connection of a call for said radio subscriber;
first announcement means, connected to said mobile switching means, for making a reception announcement through said mobile switching means and in response to an incoming call from a calling subscriber for a call-back automatic announcement service, said reception announcement requesting the calling subscriber to provide a calling number and a called number;
registering means for registering the calling and called numbers provided by the calling subscriber;
monitoring means for monitoring congestion of the radio paging channel of said radio base station, said monitoring means outputting a detection signal which indicates a reduction of congestion of the radio paging channel when a usage of the radio paging channel becomes lower than a preset level;
outgoing call control means for generating an outgoing call to a called subscriber in response to the detection signal from said monitoring means on the basis of the called number registered in said registering means; and
second announcement means, connected to said mobile switching means, for converting the calling number registered in said registering means into a speech signal, and for making a call-back announcement, including the convened speech signal, to the called subscriber through said mobile switching means when the called subscriber responds to the call from said outgoing call control means.

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.

4. A system for reducing congestion of a radio paging channel, comprising:
-
a radio base station having a radio paging channel for connection with a radio telephone; a reception announcement trunk for performing a receiving operation to request a calling number and a called number from a calling subscriber upon reception of an incoming call for a call-back automatic announcement service from the calling subscriber; a dual tone multi frequency (DTMF) receiver for receiving the calling and called numbers provided by the calling subscriber through DTMF signals; a central control section for monitoring congestion of the radio paging channel, said central control section registering the calling and called numbers received through said DTMF receiver and calling a called subscriber on the basis of the registered called number when a usage of the radio paging channel becomes lower than a preset level; a call-back announcement trunk for converting the calling number registered in said central control section into a speech signal to request a call-back of the called subscriber when the called subscriber responds to the call from the control section; and a mobile switching center for selectively performing connection control among the calling subscriber, the called subscriber, said reception announcement trunk, said call-back announcement trunk, and said receiver. - View Dependent Claims (5)
