Systems and methods for root cause analysis of performance problems of mobile network

Selection from a network event counter pool, selects a plurality of candidate counter associated with performance metrics, the candidate counter, grouped into similar counter cluster, each cluster, one or more representative counters and, a representative counter selected, be adapted to the model of the performance metrics by determining a set of representative counter most associated with performance metrics, to identify the cause of the change of performance metrics in a network which is a method and system.
