Radio paging method of arranging message information with reference to a key code and a base station and a pager receiver for use in the method
First Claim
1. A radio paging method for use in transmitting radio calling signals from a base station to pager receivers, said radio calling signals including message information originating from at least one subscriber station and specified by a plurality of species, said radio paging method comprising the steps of:
- providing a plurality of key codes for the respective species;
receiving at said base station from a subscriber'"'"'s substation a call number signal assigned to one of said pager receivers that is selected at said subscriber'"'"'s substation;
requesting from said base station, in response to the received call number signal, said subscriber'"'"'s substation to select one of said key codes;
receiving the selected key code at said base station;
requesting from said base station, in compliance with the received key code, said subscriber'"'"'s substation to convey the message information to be transmitted to the selected one of said pager receivers;
receiving the conveyed message information at said base station; and
transmitting from said base station, as one of said calling signals, to said pager receivers said call number signal and a message signal carrying the received key code and the received message information.

Abstract
In a radio paging method of transmitting message information from a subscriber'"'"'s substation (32) through a base station (30) to pager receivers (31) in the form of a radio calling signal, the message information is divided into a plurality of species to which key codes are assigned, respectively. When a selected one of the key codes is indicated from the substation prior to transmission of the message information, the base station sends a request to the substation in compliance with the selected key code to receive, as the message information, a message indicated by the request. The indicated message preceded by the selected key code is carried from the base station to the pager receivers by the radio calling signal. Each pager receiver reproduces the indicated message with reference to the selected key code. The substation comprises a push-button telephone set to send each message to the base station. Preferably, an audio response unit (46) is included in the base station to send the request by the use of an audio signal. It is also preferred that the radio calling signal should comprise call number signals of a low bit rate for calling selected ones of the pager receiver with the message information transmitted in the radio calling signal either at a high bit rate or at a plurality of high bit rates.

5. A base station for use in a radio paging system in transmitting radio calling signals to pager receivers of said radio paging system, said radio calling signals including message information of a plurality of species, said base station comprising:
-
first means responsive to a call number signal assigned to one of said pager receivers that is selected at a subscriber'"'"'s substation coupled to said base station, for sending a first request signal to said subscriber'"'"'s substation, said first request signal requesting said subscriber'"'"'s substation to select one of a plurality of key codes which are preliminarily assigned to the respective species; second means responsive to the selected one of said key codes for sending a second request signal to said subscriber'"'"'s substation, said second request signal requesting said subscriber'"'"'s substation to produce the message information to be transmitted to the selected one of said pager receivers; and transmitting means responsive to said call number signal, said selected key code and the message information produced at said subscriber'"'"'s substation for transmitting, as one of said radio calling signals, said call number signal and a message signal carrying said selected key code and the message information produced at said subscriber'"'"'s substation. - View Dependent Claims (6, 7, 8, 9, 10)

11. A pager receiver responsive to a reception calling signal including a general call number signal for providing an alert signal and a message display when said general call number signal is a specific call number signal assigned to said pager receiver and is followed by a message signal successively carrying a selected one of a plurality of key codes and message information of a selected one of species to which said key codes are assigned, respectively, said pager receiver comprising:
-
detecting means responsive to said reception calling signal for detecting said specific call number signal to produce a detection signal representative of detection of said specific call number signal; alerting means responsive to said detection signal for providing said alert signal; reproducing means energized by said detection signal and responsive to said message signal for reproducing said message information with reference to the key code indicated by said message signal; and display means for displaying said reproduced message information as said message display. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
