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.

Telecommunications network system and method

A distributed features system is disclosed which permits a telecommunication network to accommodate the creation of open multimedia services. It is an object of the present invention to create an architecture that facilitates modularity and compositional service creation. It is another object of the present invention to support multimedia services, e.g. services that include voice, graphics, video and text components. It is another object of the present invention to provide an architecture that is general, flexible, permits third party feature development, and can interact with other networks.

Routing extensions for telecommunication network system and method

A distributed features system is disclosed which permits a telecommunication network to efficiently distribute data related to network addresses.

Routing optimizations for telecommunications network system and method

A distributed features system is disclosed which permits a telecommunication network to accommodate the creation of open multimedia services. In accordance with an embodiment of the present invention, protocol extensions for a distributed feature system are disclosed which accommodate a broader range of media choices than conventional telephony. Protocols are disclosed for internal calls between modules in the distributed feature system that permit a module to open and close any number of media channels to be utilized in the communication usage. A protocol is also disclosed for internal calls between modules in the distributed feature system that is more appropriate for a packet-switched reference implementation.

Protocol extensions for telecommunications network systems and method

It is an object of the present invention to provide a general-purpose media layer for a distributed feature system. In accordance with an embodiment of the present invention, a distributed feature system environment is disclosed in which paths carrying media, e.g. voice or text, are fully separated from signaling paths. A plurality of media processing components are utilized to establish media channels separate from signaling channels and wherein each media processing component is assigned to one or more feature components in the distributed feature system.
