Wide area paging sevice processing method and apparatus of a radio paging system

#This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C .sctn.119 from an application entitled Wide Area Paging Service Processing Method Of Radio Paging System earlier filed in the Korean Industrial Property Office on the 21st of July 1995, and there duly assigned Serial No. 21626/1995 by that Office.

#1. Field of the Invention

#The present invention relates to a wide area paging service processing for radio paging systems, and more particularly, to a wide area paging service processing radio system providing subscribers with paging service even when a radio pager subscriber moves into another area with a paging receiver.

#A more complete appreciation of the invention, and many of the attendant advantages thereof, will be readily apparent as the same becomes better understood by reference to the following detail description when considered in conjunction with the accompanying drawings in which like reference symbols indicate the same or similar components, wherein:

#FIG. 1 is a block diagram illustrating a representation of a hypothetical typical general radio paging system;

#FIG. 2 is a block diagram illustrating a radio paging system constructed in accordance with the principles of the present invention;

#Turning now to the drawings, FIG. 1 represents a generalized block diagram illustrating a radio paging system of the type used in an effort to give radio paging service processing operation within the single range of a local area. In this paging servicet, when the subscriber of a public switched telephone network 100 calls a paging receiver, the call is connected from public switched telephone network 100 to radio paging system 200. At this time, an incoming processor 201 of radio paging system 200 connects to the call, and a telephone number translator 202 receives a pager subscriber's telephone number, translates it and then, if the received telephone number is an intra-office subscriber's telephone number, connects the call to a pager terminal PT 203. Then, pager terminal 203 generates a signal indicating that a call connection was established, and requests transmitter 300 to perform a radio call after storing information to be displayed in a paging receiver. A this time, if transmitter 300 transmits a radio paging signal, a corresponding paging receiver is called. When a subscriber with the paging receiver is out of the range corresponding to a local area, however, he can not receive the radio call.

#The radio paging system described above can not provide radio paging service within an area other than the particular local area assigned for the corresponding paging receiver.

#FIG. 2 illustrates a block diagram of a wide area radio paging system constructed according to the principles of the present invention wherein PSTN 12 is a public switched telephone network, and TDX-PS 14 is a paging system having a switching function. Paging system 14 may be constructed with an incoming processor 16, a telephone number translator 18, an access switching subsystem-paging terminal (ASS-PT) 20, a wide area call processor 22 for processing the wide area call and a message transfer part 24. Incoming processor 16 interfaces a radio paging incoming call from public switched telephone network 12 to the system, and telephone number translator 18 translates and switches the incoming call from incoming processor 16. Then, if the translation result is an intra-office incoming call, access switching subsystem-paging terminal 20 transmits a radio paging signal to a transmitter 26 corresponding to an intra-office area. When a call is a wide area call, wide area call processor 22 requests message transfer part 24 to transmit the wide area paging message to paging systems of other areas.
