Summary - Y.3189 (12/2025) - Network slicing in satellite-terrestrial integration in IMT-2020 networks and beyond

Network slicing is a key IMT-2020 feature that supports heterogeneous services. Network slicing allows the IMT-2020 network operator to provide dedicated logical networks with customer-specific functionalities. In the meantime, the satellite and IMT-2020 network integration is expected to realize global three-dimensional coverage and ultra-wide-area broadband access capabilities anytime, anywhere. Specifying network slicing management and orchestration in satellite-terrestrial integration is essential.
Recommendation ITU-T Y.3189 specifies requirements, overall framework, mechanisms and security considerations of network slicing in satellite-terrestrial integration in IMT-2020 networks and beyond.
