Sequence Flows for OOF based PCI Optimization based on 3 different triggers:
(Flow 1) - From SO (new cell addition),
(Flow 2) - From SDNC(R) (RAN config change)
(Flow 3) - From DCAE (fault)
Steps for Flow 1, Trigger from SO - Recommended PCI for new cell addition
Step | Component | Functionality | User Stories |
|---|---|---|---|
| Design time | |||
| 1 | SDC, CLAMP | PCI Optimization service and automated loop defined in SDC and CLAMP | |
| Deployment time | |||
| 2 | Policy, PCI-Handler-MS, OOF, SO, SDNC(R), AAI, DCAE Collector | Modules loaded with changes for PCI Optimization | |
| Run time | |||
| 3(a) | SO | SO prepares to add new cell. (? SO updates AAI with information for new cell ) | |
| 4(a) | SO, PC-Handler-MS | Request for PCI Recommendation for new cell SO requests PCI-Handler-MS to provide PCI recommendation for new cell | |
| 5 | PCI-Handler-MS, Policy | Fetch configuration policies PCI-Handler MS fetches policies that specify how PCI-Handler-MS will respond to triggers or requests from SO, from DCAE (via DMaaP), SDNC(R) (via DMaaP), PCI-Handler-MS analyzes config change to detect pre-defined signature which will trigger PCI Optimization due to config changes (e.g. Nbr list) | |
| 6 | PCI-Handler-MS, OOF | Request for PCI optimization for network region. PCI-Handler MS invokes OOF for pre-defined workflow for PCI Optimization via REST API.This call includes data for the cell and the network reqion involved. | |
| 7 | OOF, Policy | Fetch PCI optimization policies OOF fetches policies that specify how OOF will execute PCI optimization in response to PCI request for optimization | |
| 8a | OOF, AAI | Fetch Inventory data for cells in the region OOF fetches inventory and topology of cells in network region from AAI | |
| 8b | OOF, SDNC(R) | Fetch Config data for cells in the region OOF fetches PCI and Nbr List config data for cells in network region from SDNC(R) | |
| 9 | OOF, PCI-Handler-MS | Recommended PCI configuration OOF provides PCI recommendation to PCI-Handler-MS in response to the request from | |
| 10 | PCI-Handler-MS, SO | Recommended PCI configuration PCI-Handler-MS provides PCI recommendation to SO |

| 10 | PCI-Handler-MS, Policy | Recommended PCI configuration PCI-Handler-MS provides PCI recommendation to Policy | |
| 11 | Policy, SDNC(R) | PCI Configuration decisions Policy sends message to SDNC(R) with instruction for configuration changes | |
| 12 | SDNC(R), RAN | Change PCI Configuration SDNC(R) applies config changes | |
| 13 | SDNC(R), AAI | Update Inventory SDNC(R) updates inventory as needed for PCI config change |
