Abstract

The present invention provides methods and apparatus for determining the closeness of neighbor cells to a user terminal. A user terminal performs measurements and sends its measurements to a closeness determination node. The closeness determination node computes a closeness fingerprint based on measurements received from the user terminal and stores the closeness fingerprint in a closeness database. When the closeness of a set of neighbor cells to a user terminal is to be determined the user terminal may perform fingerprint measurements and send the fingerprint measurements to the closeness determination node. The closeness determination node may then select a set of neighbor cells that are closest to the user terminal based on the comparison of the received fingerprint measurements to the closeness fingerprints stored in the closeness database.
