Abstract

A next generation service node (NGSN) for providing advanced interactive voice response (IVR) services within a telecommunications network. The NGSN includes intelligent peripherals implemented as network audio servers, and application servers which execute customer application files to perform IVR services. The NGSN provides reliability through redundancy of application servers, including automatic application server failover within a node, and automatic node failover between NGSNs. The NGSN features include modular software and hardware architecture with internal function encapsulation. This allows multiple vendors products to be used and provides a common signaling interface to be used to any switch network. Other NGSN features include an open systems architecture with improved scaleability and increased application processing capability.
