Summary - Q.5016 (01/2026) - Signalling architecture of fixed, mobile and satellite convergence for IMT-2020 networks and beyond

Fixed, mobile and satellite convergence (FMSC) are the capabilities that provide services and applications to end users regardless of the fixed, mobile or satellite access technologies being used and independently of the users' location.
Recommendation ITU-T Q.5016 specifies the signalling architecture in FMSC networks for IMT2020 and beyond, focusing on interfaces among network functions, and between satellite-based and landbased networks.
