TRAJECTORY BASED PERFORMANCE MONITORING IN A WIRELESS COMMUNICATION NETWORK

For each of a plurality of wireless devices, signal strength measurements performed by the wireless device are collected. The signal strength measurements are collected with respect to a plurality of cells of the wireless communication network. Further, based on the signal strength measurements, a plurality of zones of the wireless communication network is determined. Each zone indicates a position of the wireless device with respect to the cells when performing a respective one of the signal strength measurements. Further, for each of the wireless devices, a respective trajectory is determined from a sequence of the zones passed by the wireless device. Further, performance data related to the wireless devices are collected, and the performance data are filtered based on the trajectories.
