Abstract
The present invention provides a method and wireless communication system (100) for verifying a position of a mobile station (102). The system (100) determines whether the mobile station (102) is located within a checkpoint area (130). If so, the system (100) then compares a mobile station position of the mobile station (102) within the checkpoint area (130) and a checkpoint position (128) corresponding to the checkpoint area (130) to generate a result. The system (100) thereafter determines whether the result exceeds a predetermined error tolerance. The system (100) indicates an error associated with the position of the mobile station (102) if the result exceeds the predetermined error tolerance.
Claims22
A method for verifying a position of a mobile station in a wireless communication system, the method comprising the steps of:
- determining whether the mobile station is located within a checkpoint area;
- comparing a mobile station position of the mobile station within the checkpoint area and a checkpoint position corresponding to the checkpoint area to generate a result;
- determining whether the result exceeds a predetermined error tolerance;
- and
- indicating an error associated with the position of the mobile station if the result exceeds the predetermined error tolerance.
A method for verifying a position of a mobile station in a wireless communication system, the method comprising the steps of:
- determining whether the mobile station is located within a checkpoint area;
- comparing a first mobile station position of the mobile station within the checkpoint area and a checkpoint position corresponding to the checkpoint area to generate a first result, and comparing a second mobile station position of the mobile station within the checkpoint area and the checkpoint position corresponding to the checkpoint area to generate a second result;
- determining whether at least one of the first result and the second result exceeds a predetermined error tolerance;
- and
- indicating an error associated with the position of the mobile station if at least one of the first result and the second result exceeds the predetermined error tolerance.
A wireless communication system for verifying a position of a mobile station comprising:
- a memory portion adapted to store a checkpoint position corresponding to a checkpoint area;
- a position circuit adapted to generate a mobile station position of the mobile station in response to a detection that the mobile station is within the checkpoint area;
- and
- a processor coupled to the memory portion and the position circuit, the processor being operable to compare the mobile station position and the checkpoint position to generate a result, and indicate an error associated with the position of the mobile station if the result exceeds a predetermined error tolerance.
