1. A method for reducing power consumption of a mobile station, comprising:

  • combining a plurality of received signal-derived parameters of a cellular system, a position of the mobile station derived from a cellular system positioning function, and a position of the mobile station derived from a satellite-based positioning function to obtain a value that is indicative of a presence or absence of motion of the mobile station;

    comparing the value to a motion threshold; and

    when an absence of motion is detected, reducing the power consumption of the mobile station by selectively decreasing the usage of mobile station cellular system functions, the cellular system positioning function and the satellite-based positioning function.
