qp-driver Overview¶
QP Driver is an Xapp in the traffic steering O-RAN use case. There are four total Xapps:
- Traffic steering, which sends “prediction requests” to QP Driver (this)
- QP Driver (this) 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
- QP Predictor which predicts (?) and sends that prediction back to Traffic Steering
- the fourth Xapp is called KPIMONN which populates SDL in the first place
So in summary, the QP Driver xapp is a helper function that sits between Traffic Steering and QP Predictor.
