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.
1. A method of providing a location based service to a roaming packet data communication device, comprising: establishing, via an intermediary home service provider location manager, an Internet Protocol (IP) subscriber traffic data channel between said roaming packet data communication device and a
1. A method of providing a location based service to a roaming packet data communication device, comprising: establishing, via an intermediary home service provider location manager, an Internet Protocol (IP) subscriber traffic data channel between said roaming packet data communication device and a visited service provider location manager to provide location service for said roaming packet data communication device;receiving at said intermediary home service provider location manager, via said established IP subscriber traffic data channel, a location based service request for said roaming packet data communication device; andtransmitting, from said intermediary home service provider location manager, said location based service request to said visited service provider location manager. 2. The method of providing a location based service to a roaming packet data communication device according to claim 1, further comprising: encapsulating, at said intermediary home service provider location manager, said location based service request. 3. The method of providing a location based service to a roaming packet data communication device according to claim 1, wherein said roaming packet data communication device comprises: a mobile telephone. 4. The method of providing a location based service to a roaming packet data communication device according to claim 1, wherein said roaming packet data communication device comprises: a personal data assistant (PDA) device. 5. The method of providing a location based service to a roaming packet data communication device according to claim 1, wherein said roaming packet data communication device comprises: a wireless email device. 6. The method of providing a location based service to a roaming packet data communication device according to claim 1, wherein said roaming packet data communication device comprises: a wireless device including a camera. 7. An intermediary home service provider location manager for providing a location based service to a roaming packet data communication device, comprising: an Internet Protocol (IP) subscriber traffic data channel interface to establish, via said intermediary home service provider location manager, an IP subscriber traffic data channel between said roaming packet data communication device and a visited service provider location manager to provide location service for said roaming packet data communication device;a receiver at said intermediary home service provider location manager to receive, via said established IP subscriber traffic data channel, a location based service request for said roaming packet data communication device; anda transmitter, at said intermediary home service provider location manager, to transmit said location based service request to said visited service provider location manager. 8. The intermediary home service provider location manager for providing a location based service to a roaming packet data communication device according to claim 7, further comprising: an encapsulator, at said intermediary home service provider location manager, to encapsulate said location based service request. 9. The intermediary home service provider location manager for providing a location based service to a roaming packet data communication device according to claim 7, wherein said roaming packet data communication device comprises: a mobile telephone. 10. The intermediary home service provider location manager for providing a location based service to a roaming packet data communication device according to claim 7, wherein said roaming packet data communication device comprises: a personal data assistant (PDA) device. 11. The intermediary home service provider location manager for providing a location based service to a roaming packet data communication device according to claim 7, wherein said roaming packet data communication device comprises: a wireless device including a camera. 12. The intermediary home service provider location manager for providing a location based service to a roaming packet data communication device according to claim 7, wherein said roaming packet data communication device comprises: a wireless email device.
