Abstract

A system and method for enabling two or more communication systems, each supporting a different and possible incompatible signaling protocol, to communicate with each other where the system and method are not located within any of the affected systems and for enabling a mobile station to utilize features supported by the visited system even if its home system does not support the feature. The system of the present invention is a signaling gateway that is coupled to a communications signaling network. or the signaling gateway can be coupled directly to the incompatible systems. Communication signals that are transmitted from a first communication system to a second communication system and transmitted from the second network to the first network are received and transmitted by the signaling gateway. The protocols used by the first and second communication system are not fully compatible in that some (or all) of the signaling commands used by the first communication system do not translate directly into signaling commands understood by the second communication system.
