ABSTRACT:
A method and mobile device that self-terminates a media service if an out-of-coverage condition is detected. The media service operates on top of a connectionless peer-to-peer packet-based transport protocol. The out-of-coverage condition may relate to the mobile device itself or to a remote mobile device engaged in the media service. The loss of coverage by the remote mobile device may be detected by observing whether the remote mobile device has failed to send any data packets for more than a predetermined period of time. If an out-of-coverage situation is detected, then the method or device initiates service cancellation or release.
