Abstract
A method and an apparatus for generating reference signatures in a cellular wireless communications system are provided. A first signature is obtained for a mobile communication unit at a first location. The first signature comprises first location information, a first timestamp, and radio frequency measurement information, but lacks identification information. The first signature is compared to signatures in a database, to identify a second signature having location information and a timestamp corresponding to the first location information and first timestamp. A reference signature is created by combining at least part of the first signature, such as the radio frequency information, with the second signature. The first signature is from an anonymized call. The second signature may be from an application operational on the communication unit, or from a social media website, and may comprise identification information for the communication unit or user.
