The invention relates to a system that enables power to be selectively applied to GPS circuitry in a cellular telephone or other mobile device only when a specific user input is detected. In one embodiment, power to the GPS circuitry may be enabled only when the user strikes the keys “9-1-l.” In other embodiments, other types of GPS enablement or disablement may be employed, such as selectively decoupling the GPS antenna. In another embodiment, the user may depress a privacy bypass button, which alternately enables and disables power to the GPS circuitry. Cellular telephones or other communication devices may therefore activate GPS location service during an emergency call, or when a user wishes to allow their location to be determined, but protect the privacy of that user's location and movement at other times. |

Claims1. A method for enabling operation of GPS circuitry in a mobile wireless device, the method comprising: - disabling the GPS circuitry via a GPS enabling block of the mobile wireless device responsive to a user selection to disable the GPS circuitry, wherein disabling includes removing power from the GPS circuitry, and wherein the mobile wireless device otherwise remains operational, the disabling performed responsive to a user input to disable the GPS circuitry to prevent sending location data without consent of a user of the mobile wireless device;
- detecting, via detect/control circuitry disposed in the mobile wireless device, an input at a keypad of the mobile wireless device from a user of the mobile wireless device, the input representing an emergency call; and
- enabling the GPS circuitry despite prior disablement of the GPS circuitry by the GPS enabling block, by providing power to the GPS circuitry in spite of the user selection, performed by the detect/control circuitry, and performed upon detection of the input representing the emergency call.
