ABSTRACT:
A telecommunications network system and method is presented incorporating a distributed feature composition (DFC) architecture, offering new technology for feature specification and composition. In the network architecture of the invention, customer calls are processed by dynamically assembled configurations of filter-like components: each component implements an applicable feature, and communicates with its neighbors by featureless internal calls that are connected by the underlying architectural substrate. Features are coherently accumulated, and the problem of feature interaction is rendered much more tractable.
