Mobile internet protocol (IP) location

摘要

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.

1. A method of providing location for a mobile device identified in an IP location request lacking a mobile identifier, comprising:
receiving, at a physical mobile location server, an Internet protocol (IP) location request for a current geographic location of a given mobile device identified by said IP location request only with a public Internet Protocol (IP) address, said IP location request, said IP location request including application specific information; querying a Network Address Translation (NAT) enabled device to resolve, with an identifier resolver associated with said physical mobile location server, a real mobile identifier of said given mobile device from said public IP address included with said IP location request; receiving, at said physical mobile location server, a current geographic location of said given mobile device based on said resolved real mobile identifier of said given mobile device and said application specific information included with said IP location request; and returning said current geographic location of said given mobile device to a requesting device initiating said IP location request.
