USE CASE DIAGRAM
Use cases define how different users interact with a system under design. Each use case represents an action that may be performed by a user (defined in UML as an Actor with a user persona).

Support for vertical industry scenario A in R8
Enhance UUI:
- Deign and develop tenant management portal in ONAP UUI. Through this portal, operator can create the tenant account for vertical industry tenant and assign the instantiated service instance to the corresponding;
- Design and develop separate management portal for vertical industry outside ONAP UUI. Through this portal, vertical industry can query the info which they are allowed to access.
...
- Create Tenant: Press this button. The operator maintenance officers can create one tenant account for the corresponding vertical industry;
- Assign Service: Press this button. The operator maintenance officers can assign the instantiated service to the corresponding vertical industry tenant account.
Use case UUI query A&AI for the info about assigned network instance and active xNF:
The list with yellow title is used to present info about instantiated network service instance. Three instantiated network service instances:
- 5G-RAN-Network-Service-A: Provide 5G RAN network service for large connection number scenario;
- 5G-RAN-Network-Service-B: Provide 5G RAN network service for uplink high data rate scenario；
- 5G-RAN-Network-Service-B: Provide 5G RAN service and UPF service.
The list with green title is used to present info about active xNF instance. Two active xNF instances:
- PNF: 5G-GNB-001 belongs to 5G-RAN-Network-Service-A;
- PNF: 5G-GNB-CU-002 belongs to 5G-RAN-Network-Service-B;
- PNF: 5G-GNB-DU-002 belongs to 5G-RAN-Network-Service-B;
- PNF: 5G-GNB-003 belongs to 5G-RAN-Network-Service-C;
- VNF: 5G-UPF-001 belongs to 5G-RAN-Network-Service-C.
In Support For Vertical Industry PoC, we design and develop separate Management portal outside ONAP UUI for vertical industry tenant：
- Separate Management Portal: Only vertical industry maintenance officers can access. In this page, the vertical industry maintenance officer can monitor info about the network service instances and xNFswhich have been assigned to this vertical industry tenant.
Step 1. Operator maintenance officers create one tenant account for corresponding vertical industry:
- Vertical Industry Name: Yangmei
- Password: 123456
- Vertical Industry info: A coal mining vertical industry company
The Use case UUI save the Vertical Industry Tenant info in the external database for now. The external database can be merged with CPS in the future.
Step 2. Vertical Industry maintenance officers access the Tenant Management Page and trigger the Tenant Login Function:
- Vertical Industry Name: Yangmei
- Password: 123456
The Use case UUI query the external database for vertical industry tenant info to verify the password.
Step 3. Vertical Industry (Yangmei) maintenance officers access the Tenant Management Portal. Tenant Management Portal will present the info about network service instances and xNF instances which has been assigned to the Vertical Industry (Yangmei) Tenant. Now no network service instance and xNF instance has been assigned to Vertical Industry (Yangmei) .
The Use case UUI will first query the external database for the relation (assigned-relation) between vertical industry (Yangmei) tenant and the instantiated network service instance and active xNF instance. Now no instantiated network service instance and active xNF instance have been assigned to Vertical Industry (Yangmei) Tenant. The Use case UUI doesn’t need to query AAI for assigned network service instance and xNF instance.
Step 4. The operator maintenance officers press the yellow “Assign Service” button to assign the instantiated service to the corresponding vertical industry tenant account:
- 5G-RAN-Network-Service-B à Vertical Industry Yangmei
- 5G-RAN-Network-Service-C à Vertical Industry Yangshan
The Use case UUI will save the relation (assigned-relation) between vertical industry tenant and the instantiated network service instance and active xNF instance in the external database.
Step 5. Vertical Industry (Yangmei) maintenance officers access the Separate Management Portal. The Separate Management Portal will present the info about network service instances and xNF instances which has been assigned to the Vertical Industry (Yangmei) Tenant. Now one network service instance (5G-RAN-Network-Service-B) has been assigned to Vertical Industry (Yangmei). And the xNF instances (5G-GNB-CU-002 and 5G-GNB-DU-002) which belongs to the network service instance (5G-RAN-Network-Service-B) has also been assigned to Vertical Industry (Yangmei) .
The Use case UUI will first query the external database for the relation (assigned-relation) between vertical industry (Yangmei) tenant and the instantiated network service instance and active xNF instance. Now one instantiated network service instance and active xNF instance have been assigned to Vertical Industry (Yangmei) Tenant. The Use case UUI will then query AAI for the detailed info about 5G-RAN-Network-Service-B, 5G-GNB-CU-002 and 5G-GNB-DU-002.
Step 6. Vertical Industry (Yangshan) maintenance officers access the Separate Management Portal. The Separate Management Portalwill present the info about network service instances and xNF instances which has been assigned to the Vertical Industry (Yangshan) Tenant. Now one network service instance (5G-Network-Service-C) has been assigned to Vertical Industry (Yangshan). And the xNF instance (5G-GNB-003 and 5G-UPF-001) which belongs to the network service instance (5G-Network-Service-C) has also been assigned to Vertical Industry (Yangshan) .
The Use case UUI will first query the external database for the relation (assigned-relation) between vertical industry (Yangshan) tenant and the instantiated network service instance and active xNF instance. Now one instantiated network service instance and active xNF instance have been assigned to Vertical Industry (Yangshan) Tenant. The Use case UUI will then query AAI for the detailed info about 5G-Network-Service-C, 5G-GNB-003 and 5G-UPF-001.
