Summary - Y.3224 (08/2025) - Fixed, mobile and satellite convergence – Requirements and framework for in-network aggregated federated learning for enabling artificial intelligence in IMT-2020 networks and beyond

Fixed, mobile and satellite convergence (FMSC) is the capability that provides services and applications to end users regardless of the fixed, mobile or satellite access technologies being used. This Recommendation specifies the requirements and framework for in-network aggregated federated learning (FL) to enable artificial intelligence (AI) in FMSC networks. In-network aggregated FL will enhance network capability in FMSC to reduce outgoing data traffic from the lower network entities, consume less bandwidth and enable more efficient model aggregation over multihop networks under limited communication resources.
