Signaling models for control of B-ISDN and in-supported services

This paper identifies a set of functional objectives for signaling architectures and protocols to support services in broadband and Intelligent Networks. Using a formal methodology called Object-Oriented Analysis, we define call, connection, and channel objects. Based on these object definitions and relationships, a need for separation of call and connection control in such networks is motivated. A multi-network functional architecture treating users as entities belonging in subscriber networks, and servers as entities separated from switches, is described. Service-specific client-server based protocols are identified as being well-suited for inter-entity communication in this architecture.
