Summary

Recommendation ITU-T Y.3112 describes the concept of network slicing and use cases of multiple network slicing. The multiple network slicing enables a single device to simultaneously connect to different network slices. The use case describes the slice service type (SST) for indicating a specific network slice and the slice user group (SUG) for precisely representing the network slice in terms of performance requirements and business models. This Recommendation also specifies the high-level requirements and high-level architecture for multiple network slicing in IMT-2020 network.
