Determining conflicts between KPI targets in a communications network

A node in a communications network, the node comprising:

• a memory comprising instruction data representing a set of instructions;
• and
• a processor configured to communicate with the memory and to execute the set of instructions, wherein the set of instructions, when executed by the processor, cause the processor to:
• obtain Key Performance Indicator, KPI, targets for a plurality of KPIs, in the communications network;
• determine relationships between the KPIs using a model trained using a graph-based machine learning process, wherein each relationship describes a manner in which changing a network configuration to alter a first one of the KPIs affects a second one of the KPIs;
• and
• determine one or more conflicts between the KPI targets, using the relationships.
