Summary

The addition of IP mobility in access networks impacts the functionality of network attachment control functions (NACF), and raises additional signalling requirements of NACF with respect to the mechanism of IP address management and the signalling flows for mobility interface. Recommendation ITU-T Q.3203 proposes the generic signalling requirements and architecture for NACF functionality defined in Recommendation ITU-T Y.2014, with considerations of interfacing the mobility management functions described in Recommendation ITU-T Y.2018.
