Summary - Y.3229 (04/2026) - Fixed, mobile and satellite convergence - Enhanced architecture for IMT-2020 networks and beyond in support of integrated user-centric service units

An integrated user-centric service unit (IUSU) supports end users in defining network and service capability profiles according to their own necessities. Fixed, mobile and satellite convergence (FMSC) is the capability of IUSU to support multiple access technologies used by various devices.
Recommendation ITU-T Y.3229 specifies the enhanced architecture, procedures and security considerations for supporting IUSU for FMSC, in the context of IMT-2020 networks and beyond. The radio aspects are out of scope of this Recommendation.
