Method and system for tracked device location and route adherence via geofencing
First Claim
1. A method for performing location analysis within a tracked device, comprising:
- receiving, at the tracked device, a set of coordinates associated with a boundary area;
obtaining, at the tracked device, a position of the tracked device;
determining, based upon the received coordinates and the detected position of the tracked device, whether the tracked device is located inside the boundary area or outside the boundary area, wherein the set of coordinates include a hysteresis value that adds a predetermined area to the outer periphery of the boundary area once the tracked device is determined to be inside the boundary area; and
generating and transmitting an alert signal if the result of the determining step is different from an immediately previous result obtained.

Abstract
A device tracking location adherence and route adherence technology, is disclosed that at least provides a tracked device receiving, a set of coordinates associated with a boundary area, and obtaining a position of the tracked device. Based upon the received coordinates and the detected position of the tracked device, a determination is made as to whether the tracked device is located inside the boundary area or outside the boundary area. An alert signal is then generated and transmitted if the result of the determining is different from an immediately previous obtained result. The system allows, for example, drastic reduction in the amount of data traffic required within a system since the tracked device performs much of the necessary processing. This is especially advantageous where a fleet of tracked devices are employed within a network.
