Communication system, operation control method, and location management server

Abstract

A communication system according to an exemplary aspect of the present invention is a communication system including a location management server for managing the location of a mobile station, a base station for deciding an exchange which accommodates the mobile station via the base station in response to a location registration request from the mobile station and making the location registration request to the exchange decided, and an exchange for making the location registration request to the location management server in response to the location registration request from the base station, wherein the location management server designates an exchange for accommodating the mobile station in response to the location registration request.

Description

[0001]This application is based upon and claims the benefit of priority from Japanese patent application No. 2006-164144, filed on Jun. 14, 2006, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a communication system, an operation control method, and a location management server. More particularly, the present invention relates to a communication system in which base stations and access gateways (AGWs) are configured in an Internet Protocol (IP) mesh network.[0004]2. Related Art[0005]In a case a base station (also referred to as a “Node B”) and an AGW as an exchange for accommodating a mobile station (also referred to as a “User Equipment” or “UE”) which is a portable telephone subscriber are configured in an IP mesh network, when the mobile station moves into an area covered by the base station, the mobile station transmits a location registration signal to t...

AI Technical Summary

Benefits of technology

[0009]It is an exemplary object of the invention to provide a communication system, an operation control method, and a location management server for enabling efficient operation and management of networks by utilizing flexibility of a network which allows free combination of a base station and an AGW.

Problems solved by technology

A first problem is that in such a communication system with base stations and AGWs being configured in an IP mesh network, a mobile station basically continues to use an AGW to which it initially registers its location and there is no mechanism that enables users to fully enjoy flexibility of a network which allows free combination of a base station and an AGW.

A second problem is that due to lack of such a mechanism for enabling users to fully enjoy flexibility of a network which allows free combination of a base station and an AGW, the AGWs have to support every service provided by portable telephone carrier networks.
