1. A method performed by a mobile device, the method comprising:
- storing data representative of one or more probabilistic models in a storage medium;
updating said data representative of said one or more probabilistic models based, at least in part, on historical statistical information for wireless signals, at least a portion of said historical statistical information being determined by said mobile device;
determining, by said mobile device, one or more particular wireless signals for which to search based, at least in part, on said updated data representative of said one or more probabilistic models, said one or more wireless signals to be transmitted by one or more wireless transmitters; and
searching for said one or more particular wireless signals, by said mobile device, to estimate a position of said mobile device at least partially in response to said determining.

Abstract
Disclosed are methods, techniques and/or systems for selecting and/or determining a strategy and/or approach for searching for signals at a mobile device. Characteristics of and/or information obtained from such searched signals may be used in estimating a location of the mobile device. In one particular example, a strategy and/or approach for searching for wireless signals may be based, at least in part, on an availability of resources at a mobile device.

52. An article of a mobile device comprising:
-
a non-transitory storage medium comprising machine-readable instructions stored thereon which are executable by a processor to; update data representative of one or more probabilistic models stored in a memory based, at least in part, on historical statistical information for wireless signals, at least a portion of said historical statistical information being determined by said mobile device; determine one or more particular wireless signals for which to search based, at least in part, on updated data representative of said one or more probabilistic models, said one or more wireless signals to be transmitted by one or more wireless transmitters; and search for said one or more particular wireless signals to estimate a position of said mobile device at least partially in response to determining said one or more particular wireless signals for which to search.

53. A mobile device comprising:
-
one or more receivers to receive and process wireless signals; and one or more processors programmed with instructions to update data representative of one or more probabilistic models based, at least in part, on historical statistical information for wireless signals, at least a portion of said historical statistical information being determined by said mobile device; determine one or more particular wireless signals for which to search based, at least in part, on said updated data representative of said one or more probabilistic models, said one or more wireless signals to be transmitted by one or more wireless transmitters; and initiate searching for said one or more particular wireless signals to estimate a position of said mobile device at least partially in response to determining said one or more particular wireless signals for which to search.

54. A mobile device comprising:
-
means for maintaining data representative of one or more probabilistic models in a storage medium; means for updating said data representative of said one or more probabilistic models based, at least in part, on historical statistical information for wireless signals, at least a portion of said historical statistical information being determined by said mobile device; means for determining one or more particular wireless signals for which to search based, at least in part, on said updated data representative of said one or more probabilistic models, said one or more wireless signals to be transmitted by one or more wireless transmitters; and means for searching for said one or more particular wireless signals to estimate a position of said mobile device at least partially in response to determining said one or more particular wireless signals for which to search.
