6.5. Operations of provisioning
6.5.1 AllocateNsi operation
6.5.1.1 Description
This operation is invoked by allocateNsi operation service consumer to request the provider to allocate a network slice instance to satisfy network slice related requirements. The provider may create a new NSI or using existing NSI to satisfy the request. The requirements in the request are compared/matched against the actual capabilitites of all candidate NSIs by the provider. If an existing NSI can be found e.g. with the right coverage and with good enough latency, it is eligible for allocation. In case not, or if networkSliceSharingIndicator is equal to "non-shared", a new NSI is created with capabilities to host the service, provided that required NSSIs can be created.
