Position Location Based On Measurement Reports In Lte Cellular Networks

This paper proposes a new method to estimate the accuracy of locating LTE cellular subscribers. The proposed method is hybrid network-based method; it depends on the Reference Signal Received Power (RSRP) measurements and the predicted cell serving area. It uses LTE measurements and cell information, together with a simple predictive model, for the user equipment (UE) geo-location in two dimensions plan. The proposed work is evaluated by comparing estimations with Global Positioning System measurements in various scenarios determined by the number of sectors and sites that UE simultaneously reports. The root mean square error is calculated for the method validation. The main result shows how the location accuracy depends on the number of reported sectors and sites.
