Abstract
Architecture and a method for a cost-effective implementation of new services using existing triggers, network elements, and messaging protocols in a telecommunications network. An industry wide uniformity is maintained among providers of the services while maximizing the utilization of the existing network, and without the need to wait for future developments of new standards or equipment. The architecture and methods utilize existing triggers to manage and control special service type calls, e.g., a prepaid call, within the network. ISDN User Part (ISUP) messaging protocol may be used for message exchange between network elements. A standard TCP/IP backbone is used for database interaction. Translation Type capabilities of the Service Transfer Point (STP) are used for intelligent call routing functions.
