METHODS AND APPARATUSES FOR LOCATION-TRIGGERED SENSOR INITIALIZATION

摘要

Methods, apparatuses, and devices for generating one or more harsh or diminished radiofrequency environments relative to a planned route of a mobile device user. In one example, a mobile device user a be routed through a harsh or diminished radiofrequency environment based, at least in part, on a sensor suite of a mobile device and/or based on a user's preferences. Prior to entry into such an environment, various sensors may be activated in a manner that permits position estimation in an absence of SPS based positioning signals and/or TPS based positioning signals.

主权项

1. A method comprising, at a mobile device:
processing acquired satellite positioning system (SPS) signals, terrestrial positioning system signals (TPS) signals, or a combination thereof, for use in computing an estimate of a position of said mobile device; activating at least one sensor in response to determining that said estimated position of said mobile device is proximate to or approaching a harsh or diminished radio frequency environment; and using measurements obtained at said activated at least one sensor to aid in obtaining a position fix based, at least in part, on acquisition of said SPS signals, said TPS signals, or said combination thereof.
