Classification: CPC G  H | IPC G  H

Claim 11:
12. The computing system of claim 8, wherein the processor configured to employ the received signal measurement data together with the reference positions to update the location fingerprint database comprises the processor being configured to perform at least one of:
a) building out a new location fingerprint database;
b) building out a new location fingerprint database using an existing fingerprint database, wherein the new location fingerprint database comprises fingerprints of a type of signal measurement different than the type of signal comprised in the existing location fingerprint database;
c) bridging a gap which exists in the location fingerprint database;
d) determining the location fingerprint database is unstable by comparing signal measurement data associated with a reference position of the reference positions with existing signal measurement data in the location fingerprint database which corresponds to the reference position;
e) determining the location fingerprint database is unstable by comparing signal measurement data associated with a reference position of the reference positions with existing signal measurement data in the location fingerprint database which corresponds to the reference position, and responsive to determining the location fingerprint database is unstable, updating the location fingerprint database by replacing the existing signal measurement data with the signal measurement data associated with the reference position;
f) when the location fingerprint database is known to be unstable, updating the location fingerprint database by replacing existing signal measurement data in the location fingerprint database which corresponds to the reference position with the signal measurement data associated with the reference position; g) determining the location fingerprint database is stable by comparing signal measurement data associated with a reference position of the reference positions with existing signal measurement data in the location fingerprint database which corresponds to the reference position, and responsive to determining the location fingerprint database is stable, merging the existing signal measurement data with the signal measurement data associated with the reference position; and
h) when the location fingerprint database is known to be stable, updating the location fingerprint database by merging existing signal measurement data in the location fingerprint database which corresponds to the reference position with the signal measurement data associated with the reference position.
