System and method for geographically locating a cellular device

摘要

A method and apparatus for geographically locating a cellular device is provided. The method includes the steps of: - determining an effective cell-area for each of a first cell and a second cell in a cellular network based on relative geographical positions and orientations of a first antenna of the first cell and a second antenna of the second cell, and - determining a handover area with which the cellular device is likely to be located when control of the device is transferred from the first to the second cell, where the determination of the handover area is derived from the effective cell area for each of the cells. An apparatus and methods for monitoring traffic flow by determining the location of a number of cellular devices using the above method is also disclosed.
