| KPIMON Overview |
| ================== |
| |
| KPIMON is an Xapp in the traffic steering O-RAN use case. |
| There are four total Xapps: |
| |
| 1. Traffic steering, which sends "prediction requests" to QP Driver |
| |
| 2. QP Driver which fetches data from SDL[4] on behalf of traffic steering, both UE Data and Cell Data, merges that data together, then sends off the data to the QP Predictor |
| |
| 3. QP Predictor which predicts and sends that prediction back to Traffic Steering |
| |
| 4. KPIMONN which collects UE/Cell metrics from base station and populates SDL in the first place (this) |
| |
| So in summary, the KPIMON xapp is a helper function that receives RAN metrics and write to SDL |
