Location management system and a paging server in a wireless ip network
First Claim
1. A location management system in a packet switched communication network adapted for wireless communication, the location management system comprising:
- wherein the packet switched communication network comprises multiple routers;
wherein at least one of the routers is an access router adapted for wireless communication with mobile nodes;
wherein an area served by one access router is a cell;
(400) at least one location area manager at least one regional location manager wherein the packet switched communication network is an Internet Protocol (IP) network;
wherein the at least one location area manager comprises a first signaling server and the at least one regional location manager comprises a second signaling server separated from said multiple routers wherein one of said at least one location area manager and said at least one regional location manager comprises means for maintaining a list of mobile nodes located within at least one location area;
wherein said at least one location area is a first predefined set of cells wherein the at least one regional location manager comprises means for managing location information within a single location management region;
wherein the single location management region is a second predefined set of cells; and
wherein the at least one location area manager and the at least one regional location manager are inter-connected and adapted to exchange information.

Abstract
The present invention relates to a location management system and a paging server in an Internet Protocol, IP, communication network that is adapted for wireless communication. The wireless IP network comprises multiple routers wherein at least one of the routers is an access router adapted for wireless communication with mobile nodes. The location management system is divided into at least one location area manager, and at least one regional location manager, the location area manager is a first signaling server and the regional location manager is a second signaling server, one of said location area manager and regional location manager comprises means for maintaining a list of mobile nodes located within at least one location area. The regional location manager comprises means for managing location information within a single location management region, and wherein the location area manager and regional location manager are connected to each other and adapted to exchange information. Furthermore, the paging server comprises means for obtaining location management information from the location management system and means for multicasting paging requests to the access routers wherein the access routers is determined by using said location management information.
