1. A method for Doppler-based control of a mobile device, said method comprising:
- receiving at a base station a wireless signal comprising at least one Global Navigation Satellite System (GNSS) Doppler frequency shift measurement corresponding to a GNSS signal received at a mobile electronic device;
determining a speed of said mobile electronic device based at least in part on said at least one GNSS Doppler frequency shift measurement, wherein an expected range rate is subtracted from a measured value indicating a speed of said mobile device and wherein said expected range rate is derived by calculating a dot product of at least one line-of-sight vector to a GNSS satellite and a velocity-in-space of said GNSS satellite;
controlling from said base station an operation associated with said mobile electronic device when said speed exceeds a speed threshold;
wherein said controlling said operation further comprises;
determining a first new speed of said mobile electronic device;
determining a second new speed of said mobile electronic device; and
transmitting a missed communication notice signal from said base station when neither of said first new speed of said mobile electronic device nor said second new speed exceeds said speed threshold, said missed communication notice signal configured to provide notification to said mobile electronic device that said communication was missed.

Abstract
Embodiments of the present invention recite a system having Doppler-based control of a mobile device. In one embodiment, at least one measured Global Navigation Satellite System (GNSS) Doppler frequency shift measurement corresponding to a GNSS signal measured at a mobile electronic device is received. The speed of the remote device is then determined based at least in part upon the GNSS Doppler frequency shift measurement. An operation of the remote device is then controlled from the base station when the speed of the remote device exceeds a speed threshold.

12. A wireless communication system comprising:
-
a transceiver at a base station configured to receive a wireless signal from a mobile electronic device, said wireless signal comprising at least one Global Navigation Satellite System (GNSS) Doppler frequency shift measurement corresponding to a GNSS signal received at said mobile electronic device; a speed determiner configured to determine a speed of said mobile electronic device based at least in part on said at least one GNSS Doppler frequency shift measurement, wherein said speed determiner subtracts an expected range rate from a measured value indicating a speed of said mobile device and wherein said expected range rate is derived by calculating a dot product of at least one line-of-sight vector to a GNSS satellite and a velocity-in-space of said GNSS satellite; a communication controller configured to control an operation associated with said mobile electronic device when said speed exceeds a speed threshold; and wherein said speed determiner is configured to determine a first new speed of said mobile electronic device and a second new speed of said mobile electronic device and wherein said wireless communication system further comprises; a missed communication notice signal transmitter configured to transmit a missed communication notice signal when neither of said first new speed of said mobile electronic device nor said second new speed of said mobile electronic device exceeds said speed threshold, said missed communication notice signal configured to provide notification to said mobile electronic device that said communication was missed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
