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. Traffic scheduling is the network capability to make scheduling policies to optimize the traffic forwarding performance, through network operations such as traffic steering, traffic engineering, traffic offloading etc., based on information collected from networks and applications. This Recommendation aims to describe the traffic scheduling for FMSC in IMT-2020 networks and beyond, including the scenarios, requirements, framework, network function enhancements and procedures.
