...
- Subnet template details will be loaded as Subscriber policy
- NSI Name will be unique in AAI
- Slice profile in NSSI is chosen based on latency (Conductor)

Let us assume that the NSI inventory is as follows:
| NSI Id | NST Id | NSSI RAN Id | NSSI Core Id | NSSI Transport Id |
|---|
| NSI-1 | NST_URLLC1 | NSSI-R-1 | NSSI-C-2 | NSSI-T-1 |
| NSI-2 | NST_URLLC2 | NSSI-R-6 | NSSI-C-4 | NSSI-T-3 |
| NSI-3 | NST_eMBB2 | ... | ... | ... |
| NSI-4 | NST_URLLC2 | NSSI-R-1 | NSSI-C-1 | NSSI-T-1 |
| ... | ... | ... | ... | ... |
| NSI-10 | NST_URLLC3 | NSSI-R-5 | NSSI-C2 | NSSI-T-4 |
Say, HAS returns the foll. solutions:
