This Recommendation specifies the capability exposure for fixed, mobile and satellite convergence (FMSC) in IMT-2020 networks and beyond. Capability exposure provides functionalities for network functions to expose their capabilities to third parties (e.g., users or other operators). FMSC is the capability that provides services and applications to end users regardless of the fixed, mobile or satellite access technologies.

This Recommendation specifies the following aspects of capability exposure for FMSC in IMT-2020 networks and beyond:

– Scenarios of capability exposure;

– Requirements of capability exposure;

– Reference points of capability exposure;

– Network function enhancements of capability exposure;

– Procedures of capability exposure;

– Security considerations.
