Mobile Positioning Technique using Signal Strength Measurement method with the aid of Passive Mobile Listener Grid

This paper proposes an enhancement for a well know method of mobile positioning based on signal strength measurements and database correlation method (DCM). Signal strength measurement is based on the view that the variation in the received signal strength is in the main, position dependent. Many works have been done previously on this method regarding the techniques used for analyzing the empirical database used to store the signal strength measurements. The proposed mobile positioning systems consists of a mobile position determination server (MPDS) installed in the operator site and a grid of mobile listeners installed in a selected locations between the mobile network radio sites, these radio listeners periodically send signal strength & network measurement reports to the mobile position determination server through any data bearer (SMS/GPRS), in order to provide an assisted data to the mobile positioning applications allowing calculations to be done without the need of conducting new drive tests when new sites are installed or new configuration parameters are applied to the existing sites
