Steps
Step | Component | Functionality | User Stories |
|---|---|---|---|
| 2 | Policy, PCI-Handler-MS, OOF, SO, SDN-C, AAI, DCAE Collector | Modules loaded with changes for PCI Optimization | |
| Run time | |||
| 3(b) | RAN, SDN-C | Config change notification RAN sends notification to SDN-C (e.g. Nbr list change) | |
| 4(b) | SDN-C | Publish config data change SDN-C publishes config data change on DMaaP. Subscribed by PCI-Handler-MS, A&AI (and others). | |
| 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), SDN-C) (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, SDN-C | Fetch Config data for cells in the region OOF fetches PCI and Nbr List config data for cells in network region from SDN-C | |
| 8b | OOF, AAI | Fetch Inventory data for cells in the region OOF fetches inventory and topology of cells in network region from AAI | |
| 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, Policy | Recommended PCI configuration PCI-Handler-MS provides PCI recommendation to Policy | |
| 11 | Policy, SDN-C | PCI Configuration decisions Policy sends message to SDN-C with instruction for configuration changes | |
| 12 | SDN-C, RAN | Change PCI Configuration SDN-C applies config changes |
