Abstract:
A transaction control layer system for a signaling gateway that encapsulates multiple signaling systems into a single signaling interface for use by a next generation service node (NGSN) deployed in a telecommunications network, comprising:means for receiving incoming messages; first performing means for performing initial processing of said incoming messages; first sending means for sending response messages based on said initial processing; second performing means for performing state-dependent processing of said incoming messages for calls and resources to produce result messages, said second performing means comprises: means for retrieving state data of said calls and of said resources on the NGSN, means for translating between a first resource identifier, specified by a switch on the telecommunications network in said incoming messages, to a second resource identifier, specified by the NGSN, means for allocating resources on the NGSN, specified by said second identifier, to said calls, and means for storing said state data of said calls and said resources on the NGSN; and second sending means for sending said result messages based on said state-dependent processing, wherein said NGSN is configured to provide interactive services for said calls.
