METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR ASSOCIATING INDEPENDENT LEGS OF A CALL IN A TELECOMMUNICATIONS NETWORK

摘要

Methods, systems, and computer program products for making call association across elements of a converged network are disclosed. A method is disclosed herein for associating independent legs of a call at a network node. According to one method, a first signaling message for setting up a first call leg is sent from a network node, the first signaling message including an identifier associated with the first call leg; a second signaling message for setting up a second call leg is received by the network node, the second signaling message including an identifier associated with the second call leg; the identifiers associated with the first and second call legs are compared, and if the values are found to have a predetermined relationship to each other, the first and second call legs are associated with each other.
