Multiple Points of Control It Can Be Done!

Abstract

Current IN standards specify only single-ended, single point of control capabilities. This allows for many services and service features for initial deployment. It is clear, however, that IN service developers would like more complicated capabilities and multiple service features to operate on a single call. This requires a means for allowing multiple points of control for a given IN call. When a single call can be influenced by multiple control entities, several problems must be solved. The IN switching system must manage delivery of call events to the respective control entities and manage call processing related to the responses from each entity. This problem can be quite complex. An extension to the connection-view concept is proposed to handle multiple points of control. This concept proposes that a connection-view is localized for each control relationship. No attempt is made to provide a single view of the entire call or connection segment to each control entity. This method solves the multiple control entity problem while providing a model in which simple modular software segments can be implemented in the switching system and orthogonal service logic programs that minimize logic for specialized service feature interactions.
