    摘要: A mobile device configured to estimate the speed at which it is moving. The mobile device includes a timing component configured to perform a plurality of Doppler shift measurements on a timing signal received by the mobile device. The mobile device also includes a processing component configured to correlate the size of the range of the plurality of Doppler shift measurements to the speed at which the mobile device is moving.

    摘要: A system and method for speed measurement of a mobile device, using an speed sensor such as a satellite navigation system or an accelerometer, does not need such speed sensor to be continually activated. The system and method make use of a monitor for monitoring at least one motion indicium for indicating that the speed of the mobile device is above an initial threshold, including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations visible to the mobile device; monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device. When the monitor determines that the mobile device may be travelling in excess of a threshold speed, a speed sensor is activated to confirm the indication. If the speed sensor determines that the mobile device is travelling at a speed below a second threshold, the speed sensor is deactivated.
