| Step | Component | Functionality | User Stories |
|---|---|---|---|
| 1 | 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), | |
| 2 | 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. | |
| 3 | OOF, Policy | Fetch PCI optimization policies OOF fetches policies that specify how OOF will execute PCI optimization in response to PCI request for optimization | |
| 4 | OOF, AAI | Fetch Inventory data for cells in the region OOF fetches inventory and topology of cells in network region from AAI | |
| 5 | 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) | |
| 6. | OOF, PCI-Handler-MS | Recommended PCI configuration OOF provides PCI recommendation to PCI-Handler-MS in response to the request from | |
| 7 | PCI-Handler-MS, Policy | Recommended PCI configuration PCI-Handler-MS provides PCI recommendation to Policy | |
| 8 | Policy, SDNC(R) | PCI Configuration decisions Policy sends message to SDNC(R) with instruction for configuration changes | |
| 9 | SDNC(R), RAN | Change PCI Configuration SDNC(R) applies config changes | |
| 10 | SDNC(R), AAI | Update Inventory SDNC(R) updates inventory as needed for PCI config change |
