    摘要: The present invention provides a redundancy mechanism for packet-based communication environments without requiring localized redundancy of session control entities. These session control entities are generally referred to as service nodes, which may act as proxies on behalf of the communication terminals being served. Instead of having a dedicated backup service node, other active service nodes, which primarily serve different groups of communication terminals, are configured to provide backup support when another service node fails. In operation, a communication terminal will periodically attempt to communicate with its primary service node. When the communication terminal detects that the attempts to communicate with the service node are unsuccessful, the communication terminal will attempt to register with a selected alternate service node, the alternate service node being a currently active service node primarily supporting another group of communication terminals. The alternate service node can then accept and support the communication terminal.

    摘要: The present invention allows a media terminal to initiate or receive a first communication session, and a control terminal to control the first communication session. The media and control terminals are generally proximate to or otherwise associated with each other. The control terminal may provide additional services associated with the communication session or for the media terminal. In addition to providing control and supporting additional services, the control terminal may support communication sessions associated with the first communication session involving the media terminal. A service node is provided to communicate with the media and control terminals to allow the control terminal to control the first communication session.
