Flow Steps and Test Cases
| Step | Component | Functionality | Test Case | Impacted API | Status |
|---|---|---|---|---|---|
| 1a | Policy | Policy updated with configuration and operational policies to support PCI Optimization | |||
| 1b | PCI Handler MS, DCAE | PCI Handler MS onboarded on to DCAE, MS operational | |||
| 1c | OOF | OOF models and solver defined to support PCI Optimization | |||
| 1d | SDN-C | SDN-C updated to support PCI Optimization. SDN-C has Config DB with config and element data | |||
| 2 | PCI-Handler MS, Policy | Fetch configuration policies PCI-Handler MS fetches, and applies policies that specify how PCI-Handler-MS will respond to config change messages from SDN-C (via DMaaP) | Ensure that PCI-Handler-MS can fetch configuration policies from Policy. | PCI-Handler-MS using direct Policy API | Not tested |
| 3 | RAN, SDN-C | Config change notification RAN sends notification to SDN-C (e.g. Nbr list change) | Ensure that SDN-C can receive a notification from RAN for a configuration parameter change (e.g. NbrList) | SDN-C southbound to RAN (netconf) | Not tested |
| 4a | SDN-C, PCI-Handler MS | Publish config data change SDN-C publishes config data change on DMaaP. Subscribed by PCI-Handler-MS, A&AI (and others). | Ensure that SDN-C can publish to DMaaP a configuration parameter change (e.g. NbrList). Ensure that PCI-Handler MS can subscribe to DMaaP and receive configuration parameter change message from SDN-C | SDN-C / DMaaP PCI-Handler-MS / DMaaP | Not tested |
| 4b | SDN-C, PCI-Handler MS | Get network config data from SDN-C | Ensure that PCI-Handler-MS can query SDN-C to get required data (e.g. cellids, nbr_list, pci, lat/lon) | SDN-C Config DB API | Not tested |
| 5 | 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. | Ensure that PCI-Handler-MS applies configuration policies, processes configuration |
| changes in steps 4a,4b, and sends a message to OOF | PCI-Handler-MS / OOF (OOF PCI API) | Not tested | |||
| 6 | OOF, Policy | Fetch PCI optimization policies OOF fetches policies that specify how OOF will execute PCI optimization in response to PCI request for optimization | Ensure that OOF can fetch optimization policies from Policy, and applies it to invoke the appropriate solver module | OOF / Policy (Policy API) | Not tested |
| 7 | OOF, SDN-C | Fetch Config data for cells in the region. OOF fetches data for cells in network region from SDN-C | Ensure that OOF can query SDN-C to get required data (e.g. cellids, nbr_list, pci, lat/lon) | OOF / SDN-C (SDN-C Config DB API) | Not tested |
| 8 | OOF, PCI-Handler-MS | Recommended PCI configuration OOF provides PCI recommendation to PCI-Handler-MS in response to the request in Step |
| 5 | Ensure that OOF provides output of PCI optimization to PCI-Handler-MS in response to request in Step |
| 5 | OOF / PCI-Handler-MS (OOF PCI API) | Not tested | |||
| 9 | PCI-Handler-MS, Policy | Recommended PCI configuration. PCI-Handler-MS provides PCI recommendation to Policy | Ensure that PCI-Handler-MS sends a message to Policy with recommendation for new PCI values for set of cells, along with reason for oprimization computation (RAN config change) | PCI-Handler-MS / Policy (DMaaP) | Not tested |
| 10 | Policy, SDN-C | PCI Configuration decisions Policy sends message to SDN-C with instruction for configuration changes | Ensure that Policy applies operational policies to PCI change recommendation, and if appropriate, sends a message to SDN-C with instruction to change PCI value to set of cells | Policy / SDN-C (DMaaP) | Not tested |
| 11 | SDN-C, RAN | Change PCI Configuration. SDN-C applies config changes | Ensure that SDN-C can send config change instruction to RAN element to change PCI value | SDN-C southbound to RAN (netconf) | Not tested |
