On ending communication, a timer ( 17 ) is started in order to watch a communication stop time interval (S 1 , S 2 ). On staring the next communication, a timer value of the timer is watched (S 5 ). If the timer value is less than a communication stop time interval threshold value, a cell search processing is carried out by using a cell search result on previous communication (S 7 ). By monitoring a communication stop time interval and by using a previous cell search result in the manner described above, a cell search circuit has an important function which realizes a high-speed cell search in the same sector (the same cell) on continuous communications and decreasing of a consumed power.
