Abstract:
An Internet Protocol (IP) multimedia subsystem for use in a telecommunication network. The IP multimedia subsystem comprises: 1) an IP switch for receiving Common Open Policy Service (COPS) protocol messages from an external IP network; and 2) a plurality of call application nodes capable of executing a plurality of Policy Decision Function (PDF) application groups. The IP switch distributes the COPS messages to the plurality of call application nodes according to a load-sharing algorithm.
