Reactive hybrid location determination method and apparatus
First Claim
1. A method for determining a location of a device using a plurality of location determination techniques available to the device, the method comprising:
- determining, by a mobile device, a location of the mobile device using a first location determination technique having a first accuracy of determination;
determining, by the mobile device, a distance from the determined location to a predetermined location;
adjusting, by the mobile device, the determined distance by a marginal distance;
determining, by the mobile device, a travel speed of the mobile device;
determining, by the mobile device, a first error distance based on the first location determination technique and the travel speed;
determining, by the mobile device, responsive to the adjusted distance being less than the first error distance, an additional location of the mobile device using a second location determination technique having a second accuracy of determination, the second location determination technique consuming more power of the mobile device than the first location determination technique and the second accuracy of determination greater than the first accuracy of determination; and
determining, by the mobile device, responsive to the adjusted distance being greater than a third error distance, an additional location of the mobile device using a third location determination technique having a third accuracy of determination, the third location determination technique consuming less power of the mobile device than the first location determination technique and the third accuracy of determination less than the first accuracy of determination.

Abstract
A method is described of using the mobile device so as to control the drain of power from the power source of the mobile device, the mobile device having at least two location determination techniques having respective power drain characteristics, the method includes selecting the location determination technique having a lower power drain characteristic the greater the determined distance of the mobile device from a predetermined location or area, and selecting the location determination technique having the greater power drain characteristic the smaller the determined distance of the mobile device from a predetermined location or area. The method thus uses the least accurate technique when furthest away and the most accurate technique when closer to a predetermined location or area.
