1. A method for locating a particular mobile station, wherein said particular mobile station is one of a plurality of mobile stations, and wireless signal measurements are capable of being obtained using wireless transmissions between each of the plurality mobile stations and a network of communication stations, each said communication station being for at least one of transmitting and receiving the wireless transmissions, comprising:

  • first providing access to at least some of a plurality of estimators for estimating locations of said mobile stations, wherein each of said at least some estimators provide a corresponding location estimate when supplied with a corresponding portion of said wireless signal measurements obtained from wireless transmissions between said mobile stations and said network of communication stations;

    second providing access to a plurality of data item collections, wherein for each of a plurality of geographical locations, there is a corresponding one of said data item collections having parts (a1) and (a2) following;

    (a1) a representation of the geographical location, and(a2) data indicative of said wireless signal measurements between one of the mobile stations and the communication stations when said one mobile station is approximately at the geographical location of (a1);

    for each of said at least some estimators and said data item collections, perform (b1) and (b2) following;

    (b1) inputting to the estimator said corresponding portion of said wireless signal measurements obtained from each of said data of (a2) for some of said data item collections for generating corresponding location estimates;

    (b2) comparing, for each data item collection (D) of at least some of said data item collections providing input in (b1) above, (b2-1) and (b2-2) following;

    (b2-1) said representation (a1) of D, with(b2-2) said corresponding location estimate resulting from the inputting of D in (b1),for determining one or more corresponding performance measurements of the estimator;

    activating one or more of said estimators with their said corresponding portions of wireless signal measurements obtained using wireless transmissions between the particular mobile station and said network of communication stations for providing an estimate of one or more locations of said particular mobile station;

    obtaining a resulting location estimate for the particular mobile station using the estimates of said one or more locations;

    wherein one of said steps of activating and obtaining is dependent upon one or more of said performance measurements.
