A clear requirement for optimisation systems is to be measurement-based (Live-Network data collected at the OSS).
Live-network data to be used for optimisation include KPIs derived from performance counters, and geolocated mobile-traces. KPIs and mobile traces provide detailed information about the network status that can be combined with predictions throughout the planning and optimisation phases.
Atoll 3.3 and its Live module allows combining predictions and measurements in a number of planning and optimisation functions: identify congestion areas where additional capacity is needed, tune antennas and network parameters, plan neighbours and codes (LTE PCI, UMTS Scrambling codes). The Atoll ACP (Automatic Cell Planning) module also uses KPIs and UE/MDT mobile traces to drive its optimisation functions and select the best sites for small cells.
