Paging system using compact hierarchical addressing
First Claim
1. A method for addressing a plurality of pagers in a paging system, each of said plurality of pagers belonging to at least one of a plurality of organizations, each of said plurality of organizations having assigned thereto an organization identifier, the paging system including a plurality of paging stations, said plurality of organizations sharing said plurality of paging stations, the method comprising the steps of:
- (a) forming an associative table having a one to one correspondence between each said organization identifier for said plurality of organizations and a plurality of compressed organization identifiers; and
(b) formulating an address word for a page to a paged pager as the compressed organization identifier associated with the organization identifier of the paged pager and a pager identifier for the paged pager.

Abstract
An hierarchical addressing mechanism for use in a paging system is disclosed. The paging system assigns a compressed organization identifier to each of the organization identifiers for the organizations that are sharing the resources of the paging system. Each of the pagers within the paging system are provided with an associative table that associates the compressed organization identifiers with organization identifiers. In operation, the paging system forms a page by appending an address word to a message. The address word includes the compressed organization identifier determined from the associative table and the pager identifier for the called pager. In this manner, a more efficient method of addressing pagers is disclosed.

8. A paging system shared by a plurality of organizations, each of said plurality of organizations having assigned thereto an organization identifier, said paging system comprising:
-
(a) at least one paging terminal, said paging terminal operative to formulate an associative table having a one to one correspondence between each said organization identifier for said plurality of organizations and a plurality of compressed organization identifiers, said paging terminal also operative to formulate a page to a paged pager and forwarding said page to said plurality of paging stations; and (b) a plurality of paging stations in communicative connection to said paging terminal and when said page is received from said paging terminal, for broadcasting said page to said paged pager; wherein said paging terminal formulates said page by adding to a message an address word, the address word including the compressed organization identifier associated with the organization identifier for the page and a pager identifier for the paged pager. - View Dependent Claims (9, 10, 11)

12. A method for receiving a page from a paging system by a pager, said paging system being shared by a plurality of organizations, each of said plurality of organizations having assigned thereto an organization identifier, said pager having stored in memory a pager identifier and an organization identifier, said page including a compressed organization identifier, a pager identifier, and a message, the method comprising the steps of:
-
(a) generating within said pager a compressed organization identifier corresponding to said organization identifier based upon data received from said paging system; (b) extracting from said page said compressed organization identifier; (c) determining whether said compressed organization identifier from said page matches said compressed organization identifier stored in said pager; (d) determining if said pager identifier of said page matches said pager identifier stored in said pager; (e) reading said message only if the compressed organization identifier of said page matches said pager generated compressed organization identifier and said pager identifier of said page matches said pager identifier stored in said pager. - View Dependent Claims (13)

14. A paging system for being shared among a plurality of organizations, each of said organizations having assigned thereto an organization identifier, said paging system operative to send a page to a pager, said paging system comprising:
-
(a) a paging terminal operative to assign a compressed organization identifier to each of said organization identifiers and for formulating said page by determining the compressed organization identifier of said paged pager and the paging identifier of said paged pager; (b) a plurality of pagers, each pager belonging to at least one of said organizations; and (c) a plurality of paging stations capable of transmitting said page to said pagers.
