Abstract: In the field of mobile and user of the mobile location determination, geo-fences are used to identify areas and regions of commercial, safety and convenience to user of the mobile computer device. The methods disclosed reduce the central processor unit cycles of the mobile computer device and thus the power drain caused by high numbers of calculations required to determine the location of the mobile computer device relative to one or more complex shaped geo-fences by minimising the number of positioning calculations that the mobile device needs to perform. For location updates required by the mobile computer device, the method applies data structures to a deconstructed geo-fence prior to distance calculations for use by a geo-fencing application running on the mobile computer device.

Abstract: A method of determining the unreliability of a location determination of a device knowing at least the prior determined location and time of determining the location of the device is described.

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.

Abstract: To determine whether a mobile device has entered a geo-fenced region, a first geo-location of the mobile device at a first time is identified. Also, a second geo-location of the mobile device at a second time is identified. A potential travel path of the mobile device is determined between the first geo-location and the second geo-location. The potential travel path is in at least two dimensions. A determination is made as to whether the potential travel path intersects with the predetermined geo-fenced region. If the potential travel path intersects the predetermined geo-fenced region by an amount that satisfies an intersection requirement, a determination is made that the mobile device entered the predetermined geo-fenced region.
