Abstract
System and method for determining when to initiate radio signal measurements to determine mobile device location. The method includes determining a plurality of locations of one or more mobile devices based on radio signal measurements. Acceleration of the one or more mobile devices between the plurality of locations is determined based on sensor measurements. A first location of a particular mobile device is determined and acceleration is measured by the particular mobile device. It is determined when to initiate radio signal measurements by the particular mobile device to determine a second location of the particular mobile device based on the measured acceleration of the particular mobile device, the determined plurality of locations of the one or more mobile devices, and the determined acceleration of the one or more mobile devices. Radio signal measurements are initiated by the particular mobile device to determine the second location of the particular mobile device.
