ITU-T Y.3204 PDF

This Recommendation specifies the service continuity for fixed, mobile and satellite convergence (FMSC) in IMT-2020 networks and beyond. The service continuity is the ability for a moving object to maintain ongoing service including maintaining current states, such as user's network environment and session for a service. FMSC is the capability that provides services and applications to end users regardless of the fixed, mobile or satellite access technologies.

This Recommendation addresses the following aspects of service continuity for FMSC in IMT-2020 networks and beyond:

• Scenarios of service continuity;

• Requirements of service continuity;

• Enablers for service continuity;

• Network function enhancements of service continuity;

• Procedures of service continuity;

• Security considerations.
