<p>A processor (206) and a receiver (202) monitor (301) a channel. The processor determines (304, 306) an average received signal quality on the channel and a first derivative of the average received signal quality. The processor then adjusts (308-336) the rate of background scanning to a value determined from an absolute value of the first derivative when the first derivative is positive and the average received signal quality is less than an acquisition threshold, and when the first derivative is negative and the average received signal quality is greater than the acquisition threshold.</p> |
