Abstract
A channel selecting system for use in a multi-channel mobile communication system. The received field strength associated with each channel is measured sequentially to select a channel in the highest field strength. Within a measurement time span for each channel, time segments in which the field strength is lower than a predetermined level is totalized. When the total reaches either a reference time length which is less than the measurement time span or expiration of the measurement time span, one channel measurement is switched to another.
