Automatic calibration of geolocation analytic systems and operator network equipment parameters

Abstract A method for calibrating geolocation analytic system in a wireless network includes receiving a first data set including measurement data associated with a mobile device connected to the wireless network from a first data source. A second data set comprising external geo-location data associated with the mobile device is received from a second data source. The first data set is compared to the second data set to estimate geo-location of the mobile device and to identify one or more errors using calibration function. The identified one or more errors are corrected based on the comparison. 20UE GNSS/MDT/ 308 202 208 Location data taeg Network Data (Predictors Ci o 4...0 310 Timing Power Othe Clutter )tork Engine 204 206 Calibration Analyzing Engine output: Eg.
