Abstract
For detecting service carriers, a received power measuring section initially carries out received power measurement in a frequency band assigned to the system, a frequency limiting section limits a service carrier seeking frequency range to the vicinity of a frequency where thus measured received power exceeds a threshold, the received power measuring section measures the received power at a frequency where a service carrier may exist within this frequency range, and the controller chooses a frequency yielding a high measured received power as a service carrier candidate frequency. Then, the cell search executing section initially executes a cell search for this candidate frequency.
