Method and system for identifying and removing stale connections on a user device

摘要

A device containing an MTA, executing a connection deletion method, determines that a connection at one of its endpoints may be abandoned after a predetermined amount of time after an on-hook event following a first call. If the MTA determines that the CMS it is coupled to has begun managing a new, or second, call, the MTA, sends a message to the CMTS it is coupled to requesting deletion of the first call, and the resources associated with it. The MTA also sends a message to the CMS requesting deletion of the connection at the endpoint of the MTA device.

1. A method for deleting stale connections at a user device, comprising:
detecting at the user device that a first call has terminated due to an extended on-hook event; determining at the user device that the first call has been abandoned by a remote call agent though the remote call agent has not deleted the call as having been terminated due to any on-hook event, an abandoned call being distinguished from a terminated call in that the resources for the first call remain allocated by the remote call agent though the first call has been detected as terminated; and releasing at the user device resources that are allocated to the call responsive to a determination that the first call has been abandoned.
