User equipment (UE) includes an architecture for handling femtocell fingerprints. The architecture may, as examples, maintain the validity and reliability of fingerprints and coordinate enhancement to existing fingerprints. The architecture also supports fingerprint creation, updating, and deletion. 1. A method comprising:establishing a central fingerprint database operable to store fingerprints for proximity detection, the fingerprints characterizing femtocells; creating the fingerprints, and storing, for the fingerprints, fingerprint components that characterize the femtocells;', 'selectively updating the fingerprint components; and', 'deleting selected fingerprints among the fingerprints; and, 'executing a fingerprint manager in communication with the fingerprint database for obtaining environmental measurements;', 'analyzing the fingerprints to find a matching fingerprint with respect to the environmental measurements; and', 'initiating a cell search for a specific femtocell that corresponds to the matching fingerprint., 'executing a proximity detector in communication with the fingerprint database, and, with the proximity detector2. The method of claim 1 , further comprising:determining a particular femtocell for enhanced fingerprinting, and in response:creating multiple fingerprints in the central fingerprint database for that particular femtocell.3. The method of claim 2 , where determining comprises:determining the particular femtocell responsive to frequency of selection of that particular femtocell.4. The method of claim 2 , where determining comprises:determining the particular femtocell responsive to recency of selection of that particular femtocell.5. The method of claim 1 , further comprising:obtaining at least some of the fingerprint components from radio resource control measurements of neighboring macrocells.6. The method of claim 1 , further comprising:obtaining at least some of the fingerprint components from positioning system measurements of ...
