Abstract
A method for a radiotelephone to scan for service in a radiotelephone system having a plurality of carriers within a corresponding geographic area includes establishing (202) a list of a predetermined number of carriers having the strongest signal strengths from cells proximate to the cell where the radiotelephone is camped. A next step includes determining (206) those proximate carriers from the list that are unsuitable for reselection by the radiotelephone. A next step includes scanning (208) for other suitable carriers within the area to substitute for those unsuitable carriers found in the determining step. A next step includes modifying (212) the list to include those suitable carriers found in the scanning step.
