Rapporteur: Mr. Zhang, Kai

The present document specifies use cases, requirements, management services and procedures for provisioning of 5G networks.

The provisioning of network slicing includes the four phases which are preparation, commissioning, operation and decommissioning:

In the preparation phase the NSI does not exist. The preparation phase includes network slice design, onboarding, evaluation of the network slice requirements, preparing the network environment and other necessary preparations required to be done before the creation of an NSI.
During the NSI lifecycle stage which include commissioning phase, operation phase and decommissioning phase, the NSI provisioning operations include:
- Create an NSI;
- Activate an NSI;
- De-active an NSI;
- Modify an NSI;
- Terminate an NSI.
