The invention refers to a method performed by a performance recommender for a wireless network, obtaining () for a plurality of cells input data, the input data comprising actual cell configuration parameter values; applying () a machine-learning model to the input data to generate, for at least a portion of the cells, one or more recommendations for changes to the cell configuration parameter values to improve uplink, UL, performance in the respective cells; and based on identifying conflicts between recommendations for different cells, partitioning () the plurality of cells into a plurality of interaction areas of neighboring cells; resolving () conflicts in recommendations for respective cells within each of the interaction areas and across different interaction areas; and for at least a portion of the cells, determining () preferred values for the cell configuration parameters to improve UL performance in the respective cells; the invention further relates to a corresponding performance recommender and a corresponding computer program.

Improving uplink performance avoiding parameter conflicts in a wireless network

A method comprises generating an advanced signaling call flow and monitoring one or more finite states for one or more calls using the advanced signaling call flow. The method further comprises determining that there is a failure in one of the one or more monitored finite states for a particular call, and comparing one or more performance indicators to one or more respective thresholds, the one or more performance indicators associated with a cell in which the particular call took place and comprising information about the cell at the time of the failure. The method further comprises flagging one or more of the one or more performance indicators that do not satisfy their respective threshold, and determining a root cause of the failure based at least in part on one or more of the one or more flagged performance indicators and the advanced signaling call flow.
