Call Connection and Service Control Protocols for Broadband Networks

New Image

This paper analyzes 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 analyze the problem. The Information Model and Object Communication Model are described at a high-level in this paper. From the Information Model, which is used to organize data, a signaling functional architecture that proposes a separation of transport from services is shown. Functional entities in which different objects reside are identified in this architecture. Based on the events used for inter-object communication as shown in the Object Communication Model, service specific Application Service Elements are defined for call, connection, channel and service control.
