In consequence of applications for the location of mobile subscriber (MS) of wireless services continue to expand, a simple and inexpensive method is needed by cellular mobile communications for locating MS. Many location technologies today use different signal measurements which have their limitation in accuracy and complexity. This paper proposes an effective estimation method for determining the MS location in a low implementation complexity and promising accuracy. The method is based on measuring a propagation delay, and then, the pseudo-distance-differences are available from the geometrical transformations between multiple base transceiver stations (BTSs). Accordingly, the MS location can be estimated from the hyperbolic location algorithm. Performing the field trial in a commercial cellular mobile network, accuracy of the proposed method shows promising results for the deployment of location-based services
