Abstract
A system and method for improving the accuracy of a location measurement within a telecommunications system is disclosed. An elliptical search area is defined about an estimated mobile terminal location within the telecommunications system. The elliptical area is an optimum area for locating the mobile terminal, with size, eccentricity, and orientation of the ellipse being determined by the configuration of base stations, the mobile terminal's position, a desired probability of coverage, and the known measurement errors in the quantities measured by the ALI technique.
