Abstract:
1. An apparatus comprising: control circuitry configured to control activation/deactivation of geographical location circuitry to provide device geographical location information according to whether motion of a mobile location device is detected, wherein the control circuitry is configured to monitor device motion over successive time periods and control operation of the geographical location circuitry in response to whether device motion has been detected over one, or a combination of more than one successive, time period, wherein the control circuitry is configured to use a first time period when device motion has been detected and a second time period when device motion is not detected, and wherein the control circuitry is configured to provide device location information immediately upon detection of device motion and then again at one regular time interval during the detection of continued motion, and at a reduced time interval upon subsequent detection of no motion.
