First Claim
Patent Images
1. A method comprising, at a mobile station:
- determining a measurement value based, at least in part, on a signal from at least one sensor on said mobile station;
selectively downloading a context parameter map from a server, said context parameter map being selected for downloading based, at least in part, on expected energy consumption and accuracy of a particular sensor of said mobile station, wherein measurements from said particular sensor correspond to one or more parameters included in said context parameter map, andestimating a location of said mobile station based, at least in part, on an association of said measurement value with said context parameter map.

Abstract
In one implementation, a method may comprise: storing a user profile indicative of at least one attribute of a user of a mobile station; determining a measurement value based, at least in part, on a signal from at least one sensor on the mobile station; and estimating a location of the mobile station based, at least in part, on an association of the at least one attribute and the measurement value with a context parameter map database.

43. A non-transitory storage medium comprising machine-readable instructions stored thereon that are executable by a special purpose computing device to:
-
determine a measurement value based, at least in part, on a signal from at least one sensor on a mobile station; selectively download a context parameter map from a server, said context parameter map being selected for downloading based, at least in part, on expected energy consumption and accuracy of a particular sensor of said mobile station, wherein measurements from said particular sensor correspond to one or more parameters included in said context parameter map, and estimate a location of said mobile station based, at least in part, on an association of said measurement value with said context parameter map.
