  • SYSTEMS, DEVICES AND METHODS FOR INCREASING LOCATION BASED SERVICE ACCURACY
    Publication number: 20090287415
    Abstract: A method of increasing location based service accuracy by correcting location data associated with a fixed source using a mobile communication device. The method includes the step of receiving, on the mobile communication device, a first set of location data. The first set of location data is originated from the fixed source such that if the location data is accurate, a physical location of the mobile communication device can be determined. The fixed source has a stored physical address which is updateable by an operator. At least a portion of the first set of location data derives from the stored physical address. The method further includes the steps of determining whether the first set of location data is accurate, and transmitting an error report to the operator when the first set of location data is inaccurate.
