scope:

This Recommendation provides an IdM framework for NGNs. The primary purpose of this Recommendation is to describe the fundamental concepts, functional components and capabilities of IdM that can be used to organize and guide structured solutions for NGNs. The scope of this Recommendation includes:

• describing the business motivations, benefits, and advantages of IdM services, and the generic capabilities used to provide identity assurance and defining IdM concepts applicable to NGN and based on the NGN functional requirements and architecture (FRA) as defined in [b-ITU-T Y.2012], Functional requirements and architecture of the NGN release 1;

• identifying and describing the functional entities, roles, relationships, enablers and communications supporting IdM services and capabilities for NGN;

• identifying and describing the intra-network relationships for supporting IdM services and capabilities within an NGN; and

• identifying and describing the relationships for supporting IdM services and capabilities between NGN providers (e.g., within a federation), and between NGN providers and other providers (e.g., inter-federation).

The framework provided in this Recommendation is intended for NGN (i.e., managed packet networks) as defined in [b-ITU-T Y.2001], General overview of NGN. However, it could be applied as appropriate to other types of networks (e.g., private corporation and enterprise networks).

This framework is intended to be used as a foundation to develop and specify specific aspects of IdM for NGNs, such as detailed requirements, mechanisms and procedures, as needed. It also provides a clear and coherent overview of the totality of IdM in NGNs.

NOTE - The use of the term 'Identity' in this Recommendation relating to IdM does not indicate its absolute meaning. In particular, it does not constitute any positive validation of a person.
