Abstract

A mobile IP location server that retrieves the location of a mobile device based on the public IP address that a mobile device is using. A mobile IP location server comprises a mobile location protocol interface, an identifier resolver, and a location manager. The mobile location protocol interface interacts with location applications and receives and responds to location requests. The identifier resolver converts a device'"'"'s public IP address to a real mobile identifier (e.g. MSISDN) and performs address conversion by either interacting with an HTTP proxy server or querying a network address translation (NAT) table. The location manager retrieves the location of a mobile device given the device'"'"'s real mobile identifier (e.g. MSISDN). A web application requests mobile IP location services by transmitting an IP request to the mobile IP location server. An IP location request contains a mobile device'"'"'s public IP address, port number, and any application specific information.

Claims

1. A mobile Internet protocol (IP) location server, comprising:

a mobile location protocol interface to receive an Internet protocol (IP) location request for location of a given mobile device;

an identifier resolver to convert a public Internet protocol (IP) address supplied in said IP location request, to a real mobile identifier of said given mobile device; and

a location manager to obtain a geographic location of said given mobile device based upon said real mobile identifier of said given mobile device.
