Key Features of ITU-T NGN Definition of NGN Next Generation Network (NGN): a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. Tomorrow’s Network Today 7 ~ 8 October Aosta, Italy 6 ITU-T Rec. Y.2001 09.10.2005 2. Key Features of ITU-T NGN Key Features of NGN Packet-based transfer; Separation of control functions among BC, call/session, and application/ service; Decoupling of service provision from transport; Support for a wide range of services based on service building blocks; Broadband capabilities with end-to-end QoS; Interworking with legacy networks via open interfaces; Generalized mobility; Unfettered access by users to different service providers; A variety of identification schemes; Unified service characteristics for the same service as perceived by the user; Converged services between fixed/mobile; Independence of service-related functions from underlying transport technologies; Support of multiple last mile technologies; Compliant with all regulatory requirements (e.g. emergency, privacy, lawful interception, etc.) 09.10.2005 Tomorrow’s Network Today 7 ~ 8 October Aosta, Italy 7 2.
