A system for monitoring carriers of peripheral zones in a mobile telecommunication system, wherein when monitoring the carriers transmitted from the base stations in peripheral zones, the mobile units deem transmissions carriers to be true carriers received from peripheral zones and monitor the same when the two conditions stand that the received field strengths of the transmission carriers are at least a certain level and that there is significant data transmitted by the transmission carriers. Due to this, the mobile units are prevented from erroneous channel switching or zone shifting due to interference or a transmission carrier from another zone which may be deemed interference.
