Methods and apparatus for increasing the reliability of signal reference maps for use in position determination

A mobile wireless device, comprising:

• means for receiving a set of fingerprint prediction maps including multiple maps and, for each fingerprint prediction map, at least one corresponding metric;
• means for determining a position of the mobile wireless device based on multiple fingerprint prediction maps in the set of fingerprint prediction maps and based on the corresponding metrics;
• and
• means for updating the metrics corresponding to the multiple fingerprint maps used to make said position determination based on the result of said position determination.

A computer program product for use in a mobile wireless device, the computer program product comprising:

• a non-transitory computer readable medium comprising:
• code for causing at least one computer to receive a set of fingerprint prediction maps including multiple maps and, for each fingerprint prediction map, at least one corresponding metric;
• code for causing said at least one computer to determine a position of the mobile wireless device based on multiple fingerprint prediction maps in the set of fingerprint prediction maps and based on the corresponding metrics;
• and
• code for causing said at least one computer to update the metrics corresponding to the multiple fingerprint maps used to make said position determination based on the result of said position determination.

A mobile wireless device comprising:

• at least one processor configured to:
• receive a set of fingerprint prediction maps including multiple maps and, for each fingerprint prediction map, at least one corresponding metric;
• determine a position of the mobile wireless device based on multiple fingerprint prediction maps in the set of fingerprint prediction maps and based on the corresponding metrics;
• and
• update the metrics corresponding to the multiple fingerprint maps used to make said position determination based on the result of said position determination;
• and
• memory coupled to said at least one processor.
