Abstract

This article summarizes the architectural aspects of a next-generation network in terms of general principles, functional representation, and typical implementation. According to the general reference model, which assumes decoupling of services and transport, NGN can be represented by multiple functional groups. One of the key implementations for session-based services, utilizing an IP multimedia subsystem, is introduced with enhanced features to meet both fixed and mobile network requirements.
