[ITU-T Y.2721], NGN identity management requirements and use cases, specifies identity management (IdM) requirements for the next generation networks (NGN). This Recommendation describes the specific IdM mechanisms and suites of options that should be used to meet the requirements specified in [ITU-T Y.2721]. In addition, it provides best practices and guidelines to support interoperability and other needs.

This Recommendation is intended to be used together with [ITU-T Y.2720] and [ITU-T Y.2721], as the fundamental architectural concepts, requirements and use cases are not repeated in this Recommendation.

NOTE – Implementers and users of the described mechanisms shall comply with all applicable national and regional laws, regulations and policies. Some specific regulations and legislations may require implementation of mechanisms to protect personally-identifiable information.
