Recommendation ITU-T Y.3157 specifies a network slice configuration in order to dynamically create and manage network slice instances (NSIs) in the International Mobile Telecommunications-2020 (IMT-2020) network. Detailed topics are methods for: creation of an NSI; provision of quality of service (QoS) to the network slice; and association of user equipment (UE) application services with the NSI.
Network slicing is regarded as a key technology in the successful deployment of the IMT-2020 network. The concept of network slicing and use cases in the IMT-2020 network are introduced in Recommendation ITU-T Y.3112.
