scope:

This Recommendation describes the functional architecture for the support of host - based node identifier (ID) and node locator (ID/locator) separation in NGN, based on the requirements provided in [ITU-T Y.2015].

This Recommendation addresses the following aspects:

- Functional architecture model for ID/locator separation in NGN;

- Identification of functions including the definition of functional entities and reference points;

- Description of relevant procedures and interactions with other components of the NGN functional architecture as defined in [ITU-T Y.2012].

This Recommendation covers only the host-based case of ID/locator separation and the separation of node ID and locator is done in the user equipment (UE) and not in the network.
