Abstract:
A method for a wireless terminal to select a control channel from a plurality of channels provided on a plurality of respective operating frequencies, the method comprising:scanning a first subset of the operating frequencies to locate a control channel that satisfies a first set of selection criteria; identifying channels during the scan of the first subset of the operating frequencies that fail to satisfy the first set of selection criteria and that have an increased probability of satisfying a second set of selection criteria; selecting a control channel from those control channels that satisfy the first set of selection criteria if such a control channel is located during the scan of the first subset of the operating frequencies; determining an order in which a second subset of the operating frequencies are to be scanned based on the identified channels; scanning the second subset of the operating frequencies in the determined order to locate a control channel that satisfies the second set of selection criteria; and selecting a control channel that satisfies the second set of selection criteria.
