Abstract
A mobile wireless communication device (200) including a wireless transceiver (210) communicably coupled to a processor (220), a satellite positioning system receiver (250), wherein the processor controls an operating mode of the satellite positioning system receiver based on satellite positioning system operating mode information received by the wireless transceiver when the mobile wireless communication device is in a vicinity of a location or will be in the vicinity on which the satellite positioning system operating mode information is based. Controlling the operating mode includes controller whether and when and the frequency with which location measurements are made.
