Abstract
A method of operating a mobile device is disclosed. A first activity of the mobile device is detected. The following two operations are executed upon detection of the first activity: (i) wireless transmission of data over a wireless data link from a communication unit of the mobile device is disabled for a period of time, and (ii) a first control signal is transmitted from a communication unit to a satellite positioning system receiver of the mobile device, the first control signal enabling processing of signal positioning system signals received by the receiver during this period of time. The size of this period of time may be predetermined or adaptable.
Claims18
A method of operating a mobile device, comprising:
- detecting a first activity of the mobile device, wherein the first activity is due to an operation carried out by a user of the mobile device, wherein the operation is the absence of speech received by a microphone of the communication unit;
- upon detection of the first activity:
- (i) disabling wireless transmission of date over a wireless data link from a communication unit of the mobile device;
- and
- (ii) transmitting a first control signal from the communication unit to a satellite positioning system receiver of the mobile device, the first control signal enabling the start of processing of satellite positioning system signals received by the receiver for a period, the data transmission remaining disabled even when a person speaks into a microphone of the mobile device, during said period.
