Out-of-coverage service termination using proxy
First Claim
1. A method of terminating a media service in a system having a wireless device, a remote termination point, and a wireless network, the wireless network including a proxy server associated with the wireless device, the method comprising the steps of:
- establishing the media service over a connectionless packet-based transport protocol operating peer-to-peer between the wireless device and the remote termination point;
sending a ping message from the proxy server to the wireless device to determine whether the wireless device remains in coverage;
determining that the wireless device is out-of-coverage based upon a lack of a response from the wireless device; and
sending a service release message from the proxy server to the remote termination point to alert the remote termination point to the out-of-coverage condition, furtherincluding a steps of setting up a media oath between the wireless device and the remote termination point for establishing the media service over said media path,wherein the proxy server comprises a service control server configured to perform said step of setting up the media path,wherein said service control server comprises a SIP proxy server.

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.

8. A proxy server for use in a wireless network in association with a mobile device engaged in a media service with a remote termination point over the wireless network, the proxy server comprising:
-
a session setup component for establishing the media service over a connectionless packet-based transport protocol operating peer-to-peer between the wireless device and the remote termination point; a ping component for sending a ping message to the mobile device to determine whether the mobile device remains in coverage; a timer for determining whether the mobile device is out-of-coverage based upon expiry of a predetermined time period without a response from the mobile device; and an out-of-coverage handler for sending a service release message to the remote termination point in response to said determination of an out-of-coverage condition, wherein said session setup component for setting up a media oath between the mobile device and the remote termination point for establishing the media service over said media path, wherein said proxy server comprises a SIP proxy server. - View Dependent Claims (9, 10, 11, 12, 13, 14)
