Object‐oriented analysis of signalling and control in broadband networks

This paper analyses the problem of providing call, connection, channel, and service control in broadband and intelligent networks to support a wide variety of services. A formal methodology called object‐oriented analysis (OOA) is used to analyse this problem. Three types of OOA models are constructed: the information model, state models and the object communication model. From these models, a distributed call processing architecture that proposes separate servers for call control, connection control, channel control and service control, is derived. Based on the events used for inter‐object communication in the object communication model, service‐specific and control‐function specific application service elements are defined as client‐server based protocols.
