Summary

Recommendation ITU-T Q.3222 provides the signalling requirements and protocol for the interface between the local transport location management physical entity and the home transport location management physical entity in the network attachment control function (NACF) block of the next generation network (NGN) release 1. When the local and the home transport location management physical entities (TLM-PEs) are the different access networks, this protocol can be used for communication between both TLM-PE instances. This Recommendation satisfies the requirements for information flows across the Ng reference point as specified in Recommendation ITU‑T Y.2014.
