Summary

The IMT-2020 network comprises an embedded capability exposure functionality that enables a third party (3rd party) to directly use a customised network slice under certain restrictions in order to efficiently provide optimized solutions for different market scenarios which have their own diverse requirements. Automated processes for orchestration and management are also important from the perspective of efficiency.

Recommendation ITU-T Y.3153 describes the requirements, architecture, key functionalities and typical procedures of network slice orchestration and management for providing network services to a 3rd party in the IMT-2020 network.
