ABSTRACT:
An intelligent intersection method and apparatus for network-based positioning include defining a first cell model having a first antenna as a center point and a second cell model having a second antenna as the center point, determining first and second distances from the first and second antennas, respectively, to a mobile station. The method and apparatus define a first circle for the first cell model using the first distance as a radius and a second circle for the second cell model using the second distance as the radius. The method and apparatus further determine first and second intersection points of the first and second circles, and determine a cost function for the first intersection point and the second intersection point relative to the first and second cell models based on parameters defining each cell to select the first or the second intersection point indicative of a location of the mobile station.
