Method and system for verifying the position of a mobile station using checkpoints
First Claim
1. 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.

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.

8. 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. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
the first mobile station position is determined by the mobile station and the second mobile station position is determined by a wireless infrastructure of the wireless communication system; and
the mobile station receives the second mobile station position from the wireless infrastructure.
