Abstract

Methods and systems are provided for allowing possible motion or lack of motion of a mobile terminal to be detected based, at least in part, on at least one wireless signal. For example, according to one method a mobile terminal may be configured to operate in a first wireless communication system and the method may include detecting motion or lack of motion of the mobile terminal based, at least in part, on at least one wireless signal from at least one terrestrial-based second wireless communication system, and in response to detecting the motion or lack of motion, initiating or stopping at least one process within the mobile terminal.
