User plane location based service using message tunneling to support roaming
First Claim
1. A method of providing a User Plane location based service to a roaming wireless device, comprising:
- establishing a roaming interface between a home LCS manager of a home wireless carrier network and a visited LCS manager of a currently visited wireless carrier network;
directing IP connectivity over the Internet capable of being transmitted through a firewall in said home wireless carrier network and through a firewall in said visited wireless carrier network; and
providing a message tunneling mechanism to provide an uninterrupted communication path between a location service system and a wireless device being located.

Abstract
An improved User Plane location based service (LBS) architecture and message flow, enabling seamless User Plane location based services even when a mobile or wireless device has roamed among different carrier networks. The present invention overcomes constraints inherent in the current protocol for roaming support defined by the Secure User Plane Location Service specification. A location system is enabled to automatically fall back to a message tunneling mechanism to ensure the security of a communication path between the location service system and the target wireless device, ensuring that the communication path is uninterrupted as the wireless device travels.
