AI Technical Summary

Problems solved by technology

Delays or errors in updating network information can result in denial of service to mobile users who should be granted access to the local network
This leads to frustration for mobile subscribers and loss of revenue for local and home COs
[0006] Obviously, the difficulty of maintaining the same home network information in each local network increases proportionally

Embodiment Construction

[0021] One or more embodiments of the invention are described below. It should be noted that these and any other embodiments described below are exemplary and are intended to illustrate rather than limit the invention.

[0022] As described herein, various embodiments of the present invention include systems and methods for determining a home network associated with a mobile station and authorizing service to the mobile station. Generally, this is achieved by centralizing home network information that used to be (traditionally) stored in each local network. The local network then accesses centrally stored information, rather than locally stored and maintained information, in order to authorize roaming users to access local services.

[0023] In one embodiment, a roaming mobile user attempts to access local services (eg, Internet access) by communicating with a packet data serving node via a wireless access network (eg, a CDMA wireless communication system). The packet data s...

Abstract

Systems and methods for determining the home network carrier associated with a mobile station and authorizing the provision of services to the mobile station using centralized storage of mobile station and home network information. In one embodiment, when a roaming mobile station attempts to access services, identifying information for the mobile station is used by a local server to query a centralized DNS server that stores a mapping of mobile station identifying information to corresponding home networks. The centralized DNS server returns an identification of the home network of the roaming mobile user, and the home network then determines whether to grant or deny the mobile station access to the local network. The mobile station identifying information may comprise an MSID such as an MIN, IRM or IMSI, which may serve as part of the address for the query to the centralized DNS server.

Description

[0001] This application is an international application filed on September 13, 2004 with the Chinese patent application number 200480026622.6 (the international application number is PCT / US2004 / 030103) and the invention title is "system and method for determining the home telecommunication bureau using a centralized server" division case. technical field [0002] The present invention relates generally to wireless communication systems, and more particularly to a method of determining the home network office of a roaming mobile station attempting to access a local network. Background technique [0003] With the proliferation of wireless devices, mobile subscribers often find themselves requesting service from service providers other than their home network provider (ie, home network carrier). The industry has adapted to this situation by proposing appropriate roaming agreements that provide services to mobile users while they are outside their home network. The home network...
