Automatic nationwide paging system
First Claim
1. In a paging system of the type wherein multiple subscribers are each provided with a subscriber receiver which responds to a uniquely coded radio transmission by providing a perceptible indication that the subscriber is being paged, and in which each subscriber is assigned to a home station which transmits said radio transmission throughout a prescribed geographic area served by that station, a method comprising the steps of:
- responding to a predetermined command originating from at least one of said subscribers by automatically transferring page data subsequently received at said home station of said one subscriber to a further station which serves a further geographic area;
for each page intended for said one subscriber and for which page data is received at said further station, transmitting from said further station the uniquely coded radio transmission to which the receiver of said one subscriber responds; and
automatically suspending transmission of uniquely coded radio transmissions intended for a subscriber by the home station of that subscriber in response to receiving a suspend command from that subscriber.

Abstract
In a radio paging system with multiple base stations covering respective geographic areas, subscribers may move freely from area to area and transfer their paging service accordingly by means of a local telephone cell. Radio-transmitted pages are confined to the specific area of the subscriber'"'"'s whereabouts. Pages are automatically stored while a subscriber is in transit from one area to another. If the subscriber has been paged during the transit period, he is automatically paged when his paging service is transferred upon arrival at his destination. Pages destined for a subscriber who is remotely located are originated in the same manner as if that subscriber were operating locally, i.e. by means of a local telephone call, whether or not the page originator knows the location of the recipient (subscriber). Pages may be originated from any area throughout the system for any subscriber regardless of his location. Pages are automatically forwarded to the subscriber and the area of origin is discernable to the subscriber from a digital readout on the paging receiver. The national land switched telephone network (or other transmission medium) may be used throughout the system to provide automatic page transfer, control and information signalling. Provision is made for automatic billing of subscribers at their home base station and for generation and collection of data for traffic analysis. The system may operate equally well using forms of transmission media other than the national switched telephone network, these include but are not limited to, packet data switching networks, satellite transmission and data networks, and telegraph switching networks. Direct leased lines could also be used if required.

4. In a nationwide paging system of the type wherein plural geographically-spaced stations each normally collect page information for page subscribers assigned to that station and emit radio transmissions within a prescribed geographic area served by that station, each radio transmission being coded to identify a specific subscriber, and wherein each subscriber carries a receiver which responds only to radio transmissions which bear that receiver'"'"'s own identification code, a method comprising the steps of:
-
in response to a command received at any station in said system from a subscriber located in a first geographic area other than that served by the home station to which that subscriber is assigned, storing at said home station the identity of the station which serves said first geographic area; in response to collection of page information for that subscriber at any station in said system, transferring the received page information to the station which serves said first geographic area; and in response to reception of said page information for that subscriber at the station serving said first geographic area, emitting from that station and only that station a coded radio transmission which identifies that subscriber. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A paging system of the type wherein multiple subscribers are each provided with a subscriber receiver which responds to a uniquely coded radio transmission by providing a perceptible indication that the subscriber is being paged, and in which each subscriber is assigned to a home station which transmits said radio transmission throughout a prescribed geographic area served by that station, said system comprising:
-
transfer means responsive to a predetermined command originating from at least one of said subscribers for automatically transferring page data subsequently received at said home station of said one subscriber to a further station which serves a further geographic area; means responsive to each page intended for said one subscriber, and for which page data is received at said further station, for transmitting from said further station the uniquely coded radio transmission to which the receiver of said one subscriber responds; and means for automatically suspending transmission of uniquely coded radio transmissions, intended for a subscriber, from the home station of that subscriber in response to receiving a suspend command from that subscriber. - View Dependent Claims (12, 13)

-
means responsive to a command received at any station in said system, from a subscriber located in a first geographic area other than that served by the home station to which that subscriber is assigned, for storing at said home station the identity of the station which serves said first geographic area; means responsive to collection of page information for that subscriber at any station in said system for transferring the received page information to the station which serves said first geographic area; and means responsive to reception of said page information for that subscriber at the station serving said first geographic area for emitting from that station and only that station a coded radio transmission which identifies that subscriber. - View Dependent Claims (15, 16, 17, 18, 19)

20. In a paging system of the type wherein multiple subscribers are each provided with a subscriber receiver which responds to a uniquely coded radio transmission by providing a perceptible indication that the subscriber is being paged, and in which each subscriber is assigned to a home station which transmits said radio transmission throughout a prescribed geographic area served by that station, a method comprising the steps of:
-
responding to a predetermined command originating from at least one of said subscribers by automatically transferring page data subsequently received at said home station of said one subscriber to a further station which serves a further geographic area, wherein said predetermined command can be selectively introduced into said system at any time from each and every geographic area served by a system station by individual subscribers irrespective of whether that system station is the home station or said further station for said subscriber, said predetermined command being introduced into said system via a prescribed transmission medium linking the station in said system; and for each page intended for said one subscriber and for which page data is received at said further station, transmitting from said further station the uniquely coded radio transmission to which the receiver of said one subscriber responds. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
