ABSTRACT
Locating the position of a mobile user with a high degree of accuracy is a trending research
interest. It holds the key to a breakthrough in many service challenges faced by operators in the
wireless communication industry. With a success in this field, it will be possible for call rates in
mobile phones to be charged based on the location a subscriber is calling from; fighting crimes
and delivering emergency services through the mobile network’s ability to detect the caller’s
position will be possible. Many techniques have been proposed or developed for locating the
position of a mobile station in a telecommunication network. Those in operation are mostly
handset-based and each technique has its limitations. These ranged from the degree of accuracy
of the location estimate and response time of the system, to the cost and ease of implementing
the technique. The same goes for the various algorithms employed by these techniques. This
work presents a novel network-based Time Difference of Arrival (TDOA) algorithm for use in
estimating the position of a caller in a 3G mobile network. It is based on geometric principles
and uses known network parameters to calculate the unknown positions of mobile users in the
network. The algorithm improved the accuracy in the estimated position of a mobile user without
incurring the mathematical complexities in hyperbolic trilateration methods conventionally used
by TDOA techniques. From the results of the simulation, the improvement in the accuracy of the
located coordinates of the mobile phone was up to 86.82% and 89.20% for the x and y
coordinates respectively. The method adds no modification in the available cellular infrastructure
and incurs no additional costs.
