1. A method of operating a global navigation satellite system (GNSS) receiver of a mobile device, the method comprising:
- determining that the mobile device has entered a traffic tunnel;
turning off the GNSS receiver based, at least in part, on;
(i) the determination that the mobile device has entered the traffic tunnel, and(ii) a determination that a length of the traffic tunnel exceeds a threshold traffic tunnel length, the threshold traffic tunnel length based on;
a determined speed of traffic inside the traffic tunnel, ora frequency at which the mobile de vice is to provide a location fix, or any combination thereof;
determining that the mobile device has exited the traffic tunnel; and
turning on the GNSS receiver based on the determination that the mobile device has exited the traffic tunnel.

Abstract
Techniques provided herein are directed toward using information from various sources to determine when the mobile device enters and exits a traffic tunnel, turning off the GNSS receiver of the mobile device when the mobile device enters the tunnel, and turning the GNSS receiver back on once it exits. For example, the mobile device can turn off the GNSS receiver based, at least in part, on a determination that the mobile device has entered the traffic tunnel, and a determined traffic tunnel length and/or estimated amount of time the mobile device will be in the traffic tunnel.

10. A mobile device comprising:
-
a global navigation satellite system (GNSS) receiver; and a processing unit communicatively coupled with the GNSS receiver and configured to; determine that the mobile device has entered a traffic tunnel; cause the GNSS receiver to be turned off, based, at least in part, on; (i) the determination that the mobile device has entered the traffic tunnel, and (ii) a determination that a length of the traffic tunnel exceeds a threshold traffic tunnel length, the threshold traffic tunnel length based on; a determined speed of traffic inside the traffic tunnel, or a frequency at which the mobile device is to provide a location fix, or any combination thereof; determine that the mobile device has exited the traffic tunnel; and cause the GNSS receiver to be turned on, based on the determination that the mobile device has exited the traffic tunnel. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

24. A non-transitory computer-readable medium having instructions embedded thereon for operating a global navigation satellite system (GNSS) receiver of a mobile device, the instructions, when executed by one or more processing units, cause the one or more processing units to:
-
determine that the mobile device has entered a traffic tunnel; turn off the GNSS receiver based, at least in part, on; (i) the determination that the mobile device has entered the traffic tunnel, and (ii) a determination that a length of the traffic tunnel exceeds a threshold traffic tunnel length, the threshold traffic tunnel length based on; a determined speed of traffic inside the traffic tunnel, or a frequency at which the mobile device is to provide a location fix, or any combination thereof; determine that the mobile device has exited the traffic tunnel; and turn on the GNSS receiver based on the determination that the mobile device has exited the traffic tunnel. - View Dependent Claims (25, 26, 27, 28)
