Abstract

A paging network which generates pages at a page source storing a plurality of subscriber files chosen from subscriber files stored at a plurality of switches located in the network. The destination to which a page is to be transmitted is determined by the network transmitting the page to the switch storing a number identical to the identification added to the page by the page source. A plurality of locations may be connected to the network with each location generating pages having a different type of information.

11. A paging network in accordance with claim 3 wherein:

the page source stores at least one information parameter associated with an identification number which is processed by a computer program to generate pages using the at least one information parameter and an information source coupled to the page source.

12. A paging network in accordance with claim 11 wherein:

the at least one information parameter comprises at least one stock price, the information source is a source of stock price information from a stock exchange and a page is generated when a stock price obtained from the source of stock price information passes a stock price limit specified by the at least one parameter.

13. A paging network in accordance with claim 3 wherein:

the page source comprises an input device for composing pages.

14. A paging receiver in accordance with claim 13 wherein:

the input device is a keyboard.

15. A paging network in accordance with claim 13 wherein:

the input device composes display information for an electronically variable sign and at least one paging receiver is located at a location of an electronically variable sign.

16. A method of transmitting a page from a page source storing a plurality of identification numbers chosen from identification numbers stored by a plurality of local switches with an identification number identifying a paging receiver to which pages generated by the page source are to be transmitted by a paging network comprising a plurality of the local switches and at least one other switch with pages including information from the page source and the identification number of the paging receiver which is to receive page chosen from one of the plurality of stored identification numbers comprising:

coupling a page from the page source to one of the switches in the network;

transmitting the page coupled to the switch to a local switch in the network having a subscriber file storing an identification number identical to the identification number contained in the page coupled to the switch;

determining a destination switch in the network to which the page transmitted to the local switch is to be transmitted from the subscriber file storing an identification number identical to the identification number stored in the page;

adding the determined destination switch to the page to which the page is to be transmitted by the network for which a destination switch has been determined; and
