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. Location service enhancement in FMSC network is a network capability to provide more accurate and reliable location information compared to existing Global Navigation Satellite System (GNSS) and mobile base station location information to meet the growing demand for location-based services. This Recommendation specifies overview, requirements, framework, procedures, security considerations, and use cases of location service in FMSC network, in the context of IMT-2020 and beyond.
