Abstract
A method includes, in a mobile communication terminal, receiving signals in a frequency band. One or more lists of entries are generated based on the received signals, each entry specifying a respective frequency channel suspected of containing a carrier of a respective Radio Access Technology (RAT). At least some of the entries are scanned in accordance with a scanning order that alternates from a first RAT to a second RAT before scanning all the entries of the first RAT. For each scanned entry, detection is made whether the respective frequency channel actually contains the carrier of the respective RAT. The detection of the carriers in the frequency band is output.
