To perform a channel inspection (200), a wireless communication device: monitors (202) a common announcement channel (CACH) until detecting that a first set of identified parameters associated with a signal on a first channel matches a second set of known parameters for the first channel; performs (204) an inspection on the first channel to determine whether the signal is of interest; and when the signal is not of interest, marks (206) the first channel to prevent another inspection from being performed on the first channel until after the channel mark is removed. The communication device then leaves (208) the first channel and continues to monitor the CACH for a change in the first set of identified parameters or an indication of an idle first channel, wherein the communication device removes (210) the channel mark on the first channel.
