Abstract

A telephone system and radio paging transmitters are combined by using dialed assigned telephone numbers to cause an information storage device to indicate radio paging areas corresponding to the dialed assigned number and, through the telephone system, to cause actuation of radio paging transmitters serving the radio paging areas to transmit a predetermined radio signal associated with the dialed assigned number. In some cases this will include a first information storage device, connecting itself to other information storage devices in order to achieve the connection to all the radio paging areas involved. Voice communication may also be provided for between the dialling party and the bearer of a radio paging receiver corresponding to an actuated paging transmitter.

means responsive to the information provided by said programmed means as to paging areas, for achieving connection through the system to the transmitter controls corresponding to transmitters for paging areas associated with said represented telephone number; and

means responsive to the information as to the value of said received subset to supply control signals characteristic thereof to said corresponding transmitter controls.

2. In a telephone system combined with means for paging telephone subscribers using radio transmitters effective with a localized area designed to provide, responsive to coded information, signals characteristic of said coded information and wherein paging receivers are provided for selective actuation by selective actuation by selective variants of said signals, such transmitters being associated with designated areas and being accessible through the telephone system;

means for storing, in association with each of a subset of digits information as to the telephone numbers of predetermined ones of said transmitters;

means for supplying to said storage means, the digital encoded form of a corresponding subset of digits forming part of a telephone number;

means associated with said storage means, responsive to receipt of such subset corresponding to a stored subset for signalling on the system to achieve connection of said storage means with each of the predetermined transmitters associate with said stored subset;

means associated with said storage means for providing to each said connected transmitter control signals to provide predetermined selective variants of said signals.

3. In a telephone paging system for uSe with transmitters effective within a localized area, controllable to provide, responsive to coded information characteristic of a paging subscriber, a radio signal for selective reception by, and actuation of, the subscriber'"'"''"'"'s paging receiver, a telephone number associated with a paging subscriber, a telephone number for achieving through said system, connection to a transmitter control for controlling each transmitter;

different transmitter controls having different telephone numbers;

means for storing, in association with digits identifying said associated telephone numbers, information identifying the telephone numbers of transmitter controls in predetermined localized areas characteristic of the associated telephone number;

means for supplying to said storage means, digits identifying the telephone number associated with said subscriber;

means responsive to such supply for establishing connections in the system between said storage means and the telephone controls of transmitter controls for the areas characteristic of the associated telephone number;

means for supplying, along said last-mentioned connections, coded information for causing said transmitters to transmit signals to selectively actuate the receiver of the subscriber having such identified telephone number.

4. Means for operating a telephone subscriber paging system in conjunction with a telephone system comprising:

storage means accessible through the telephone system having, for each of a plurality of series of digits forming a succeeding part of a telephone number, information identifying the dialed digits required to establish connections through the system to controllable transmitters;

where the dialed digits and the established connections are different for different transmitters;

said storage means being identified with a preceding series of digits, means for connecting a line in said system to said storage means when said preceding series is signaled on said lines;

means actuable on such last-mentioned connection of said line to compare a succeeding series of digits from said line with groups of digits in said storage means to determine whether or not said succeeding series corresponds to a stored group;

means responsive to ascertainment of said correspondence to dial predetermined transmitter controls in said system and to provide to said transmitters, control information characteristic of said succeeding series of digits;

said transmitter controls being designed, in response to said control information to cause said transmitter to transmit signals characteristic of said control information.

5. For operating a telephone paging system in combination with a conventional telephone system have a plurality of transmitters designed to transmit paging signals in a plurality of paging areas, wherein different paging subscribers are paged by different paging signals, controls for said transmitters being connected to be reached through said telephone system by signaling on said system of digits of the subscriber dialed-type;

different controls having different telephone numbers;

said controls being designed in response to signals received over said system, for actuating said transmitters and to be controlled to select the paging signals transitted thereby;

storage means responsive to the dialing on said system of a single paging access number for providing the designation of one or more transmitters which will broadcast a paging signal;

means responsive to said last-mentioned determination to achieve connection on said system from said responsive means to control means for said designated transmitters, and to supply signals to determine the paging signals transmitted from said transmitters.

6. A system combining radio paging service with a conventional telephone system including:
