Abstract: A method and apparatus are disclosed for building a unified network for providing voice, video, and data based on metered service on demands and IP. The unified network comprises a first network for broadband secure common channel signaling, a second network for subscriber communications and nodes of routing and switching apparatus for processing subscriber traffic, keeping subscriber information and billings. The broadband secure common channel signaling network can rout, forward, process the subscriber network signaling. The subscriber network transmits subscriber communication traffic. The nodes of routing switching apparatus process the subscriber communication data following instructions from the subscribers, the signaling network and the routing protocols. The service on demands requests are processed by the routing switching apparatus, transmitted to and processed by the signaling network.
