Out-of-coverage service termination using proxy |
摘要 |
A method and system that employs a proxy server (16) associated with a mobile device (10) in a wireless network (12), wherein the proxy server (16) monitors whether the mobile device (10) is still in coverage. The media service operates on top of a connectionless peer-to-peer packet-based transport protocol. If the proxy server (16) detects that the device (10) has lost coverage for more than a predetermined length of time, then it sends an out-of-coverage message to the other termination point engaged in the media service. The out-of-coverage message may instruct the termination point to release or cancel the service.
