Abstract

A system for enabling network convergence and interworking between multiple communications networks is disclosed. A subscriber is associated with a plurality of communications networks each utilizing its own schemes, protocols, and standards for effectuating communication therein. A main centralized database storing subscription, network, service, and location data associated with each of the communications networks is provided. A main administrative node for defining and providing new subscription, subscriber preference, and parameters is further provided. The main centralized database and the administrative node then communicate with corresponding functions within each of the communications networks to provide centralized information sharing, data control, and network resource management across the plurality of associated communications networks.
