Paging communication system
First Claim
1. A paging communication system comprising:
- a base station; and
a plurality of receivers divided into a plurality of groups, a group of said receivers being called in response to a paging signal transmitted from said base station;
said paging signal being composed of a train of frames each of which includes a plurality of fields corresponding to said groups of receivers, respectively, each of said fields being composed of a plurality of pairs of an individual calling code word, each of said code words containing an individual calling code which is assigned to each corresponding ones of said receivers and a message word containing a message which is addressed to the corresponding receiver, said message word being subsequent to said individual calling code word, each of said code words also including a group calling code word containing a group calling code which is common to the same group of receivers and a plurality of information words each of which includes an information addressed to the group subsequent to said group calling code word;
said base station comprising first means for counting the number of times that a transmission is made from said base station to each of said receivers, and second means operative to transmit first data indicating that the transmission of the information to a particular one or ones of said receivers is not allowed by putting the first data in the message word corresponding to the particular one of said receivers or by putting the first data in each message word which corresponds to each of the particular ones of said receivers;
each of said receivers comprising means for comparing the individual calling code transmitted from said base station with its own individual calling code stored therein, means for indicating the corresponding message when the received individual calling code coincides with the stored individual calling code and for indicating the corresponding information when the received group calling code coincides with its own group calling code stored therein, and third means operative to inhibit an ordinary receiving processing of the information code in response to the first data transmitted from said base station.

Abstract
A paging communication system is configured so that a plurality of receivers are called by group in response to a paging signal transmitted from a base station. The base station is provided with first circuitry comprising a plurality of timers for counting the number of transmissions to each receiver, and second circuitry operative to transmit a first kind of data indicating that the information code assigned to each of the particular receivers is masked and a second kind of data for restarting the ordinary receiving process with respect to the masked information code. Each receiver is provided with a decoder circuit operative in response to the first kind of data to inhibit the ordinary receiving process with respect to the masked code and operative in response to the second kind of data to restart the ordinary receiving process. Thus, the communication system will inhibit the information supply only to receivers which are not current in their contract payments and restart the information supply after payment of the contract fee. Further, this system can determine the appropriate charges based upon the number of calls to each individual calling number as counted by the first circuitry provided in the base station.
