摘要:
A method for providing geographic region data includes receiving geographic position data associated with a location point of a first user equipment and receiving a first radio fingerprint. The method also includes associating the received first radio fingerprint with the received geographic position data and clustering the received geographic position data to create cluster boundaries defining geographical region data. The method further includes receiving a second radio fingerprint and comparing the second radio fingerprint received from the second user equipment with previously received radio fingerprints being associated with geographic region data, and if the second radio fingerprint corresponds to a previously received radio fingerprint, associating the geographic region data of the previously received radio fingerprint with the location point of the second user equipment, and providing the geographic region data, associated with the location point of the second user equipment.
