Distributed call processing architecture (DCPA)

We propose a Distributed Call Processing Architecture (DCPA) for next generation broadband networks that will support both telephony and data communications users. DCPA features a layered architecture with modularized protocols designed to support different types of end user equipment and servers. A fast connection setup algorithm, called Parallel Connection Control (PCC), is used in networks based on the DCPA model. The Intelligent Network (IN) principle of having the network provide value-added services is combined with consistently maintaining separate modularized interfaces to different control functions of networks. The latter ensures that flexible control models, such as those used in current computer communications networks, can coexist with Intelligent Network-based models.
