scope:

This Recommendation describes the concept of network slicing and use cases of multiple network slicing where a single device is simultaneously connecting to different network slices when the device requests different services. 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. From the multiple network slicing perspective, this Recommendation specifies high-level requirements in service aspect as well as network aspect. It also specifies high-level architecture in terms of network slice and network function.
