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 media service operating over a connectionless packet-based transport protocol between the wireless device and the remote termination point, the method comprising:
- establishing the media service 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;
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; and
wherein said determining is performed if no response message is received from the wireless device within a predetermined time period.

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. The out-of-coverage condition may relate to the mobile device itself or to a remote mobile device engaged in the media service. 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. If an out-of-coverage situation is detected, then the method or device initiates service cancellation or release. The out-of-coverage message may instruct the termination point to release or cancel the service.

9. 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, the media service operating over a connectionless packet-based transport protocol, the proxy server comprising:
-
a session setup component configured to establish the media service between the mobile device and the remote termination point; a ping component configured to send 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 if no response message is received from the mobile device within a predetermined time period; 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable medium storing instructions executable by a processor within a proxy server for termination of a media service in a system having a wireless device, a remote termination point, and a wireless network, the media service operating over a connectionless packet-based transport protocol between the wireless device and the remote termination point, wherein the instructions, when executed by the processor, configure the processor to
establish the media service between the wireless device and the remote termination point; -
send a ping message from the proxy server to the wireless device to determine whether the wireless device remains in coverage; determine that the wireless device is out-of-coverage based upon a lack of a response from the wireless device; send 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; and wherein the processor is configured to determine that the wireless device is out-of-coverage if no response message is received from the wireless device within a predetermined time period.
