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;
estimating a location of said mobile station based, at least in part, on an association of said measurement value with a context parameter map;
determining a representation parameter for said context parameter map based, at least in part, on said measurement value and said estimated location;
determining a discriminative ability of said context parameter map with respect to said representation parameter;
determining an expected gain associated with said context parameter map; and
selectively downloading said context parameter map from a server based, at least in part, on a sensing capability of said mobile station, said expected gain, and said discriminative ability.

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.
