Abstract:
1. A method of controlling the usage of a wireless device, comprising the steps of: in a defining step, defining, via a mathematical description, a geographic area where use of said wireless device is restricted; and in response to an attempt to establish a communication involving said wireless device and another communication device: in an obtaining step, obtaining a set of coordinates in a specified coordinate system representative of a geographic location of said wireless device; in a first determining step, determining, based upon said mathematical description of the geographic area where use of said wireless device is restricted and said set of coordinates representing the geographic location of said wireless device, whether the geographic location of said wireless device is within the geographic area where use of said wireless device is restricted; and in a preventing step, based on a result of said first determining step, if the geographic location of said wireless device is within the geographic area where use of said wireless device is restricted, preventing the attempted communication involving said wireless device and said other communication device.
