  • receiving, at a gateway, a first message using a first signaling protocol from said IMS network, the first message being part of an IMS protocol based session;

    associating the received first message with an instance of an application selected from a plurality of applications running on said non-IMS node in accordance with an application instance identification table, the application instance identification table correlating the received first message with the instance of the application running on the non-IMS node; and

    transmitting a second message towards said non-IMS node using a second signaling protocol that is different from said first signaling protocol, said second message including an application instance identification corresponding to the instance of the associated application, the application instance identification being used to route the second message to the instance of the associated application running on said non-IMS node.
