Abstract

A method for facilitating communication sessions includes establishing a communication session between a first endpoint and a second endpoint, sending a hibernation message from the first endpoint, and receiving the hibernation message by the second endpoint. The method further includes storing, by the first and second endpoint, session state information associated with the communication session in response to receiving the hibernation message, and deactivating at least a portion of the communication session. After storing the session state information by the first and second endpoints, the method further includes retrieving the session state information by the first and second endpoints, and reestablishing the deactivated portion of the communication session.
