Summary - Y.3219 (04/2025) - Fixed, mobile and satellite convergence – Deterministic networking for IMT-2020 networks and beyond

Deterministic services are network services that provide predictable and guaranteed network behaviour in terms of key parameters such as latency, jitter, and packet loss rate. Deterministic networking refers to processes and functionalities on a network that aims to deliver deterministic services. 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. Recommendation ITU-T Y.3219 specifies the general considerations, requirements, framework, network function enhancements, procedures and security considerations of deterministic networking in FMSC network, in the context of IMT-2020 and beyond.
