A Next Generation Network (NGN) is an advanced, packet-based network that exploits multiple broadband, QoS-enabled transport technologies to provide telecommunication services. The objective of NGN is to focus on users and those service-related functions that are independent of underlying transport-related technologies. With the advent of NGN, services that are currently provided by multiple specific network-centric architectures are migrated towards a single, converged, user-centric communication network. NGN provides AAA (Anytime, Anywhere and Always on) access to users from different service providers with consistent and ubiquitous provision of services as necessary. The principles and requirements of Convergence of Fixed and Mobile Networks (FMC) and IP Multimedia Sub-layer (IMS) are likely to deliver all the desired benefits of NGN and should be carefully examined and studied.
