ABSTRACT:
A method and system that employs a proxy server associated with a mobile device in a wireless network, wherein the proxy server monitors whether the mobile device is still in coverage. The media service operates on top of a connectionless peer-to-peer packet-based transport protocol. If the proxy server detects that the device 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.
