A computing platform is provided including a processor that executes instructions for optimizing operation of a cellular network. When executing the instructions, the computing platform operates (a) to probe for information exchanged between a mobile access network and a core network; (b) to retrieve statistical KPIs generated from a plurality of network elements belonging to the cellular network; (c) to generate a predictive Key Performance Indicator (pKPI) by correlating the probed information with the retrieved statistical KPIs, which enables the computing platform to predict a trend characterizing future performance of network elements such as cells; and (d) to trigger changes in the operation of the cellular network based on the predicted trend. The probing for information exchanged between a mobile access network and a core network is carried out at a rate higher than a rate of retrieving statistical KPIs generated from the plurality of network elements.
