ABSTRACT:
A method for operating a mobile station (10) includes a first step of placing the mobile station in a camping state for receiving a control channel of a communications system. Prior to executing an evaluation of at least one other channels, the method determines if the current communications system was manually selected by a user. If not, the method executes the evaluation of the at least one other channel. If the current communications system was manually selected by the user, the method instead determines if the signal strength of the control channel is equal to or less than a threshold signal strength. If it is, the method executes the evaluation of the at least one other channel; else the method instead returns to the camping state without executing the evaluation of the at least one other channel.
