This Recommendation specifies a dynamic network slice configuration in order to dynamically create and manage network slice instances (NSIs) in the International Mobile Telecommunications-2020 (IMT-2020) network. The network slice configuration changes information about functional constituents (e.g., capacity of virtual network function (NF), capacity of virtual link and topology) in a dedicated NSI. The network slice configuration is updated when the network slice is modified according to the instructions of NSI life cycle management.

This Recommendation covers the following aspects:

– an overview of a network slice template, including its attributes and network slice key performance indicators (KPIs);

– relations between NSI modification and the configuration file;

– update procedures for dynamic network slices.
