PURPOSE:To always communicate with an optimum base station by using the property of TDMA(time division multiple access system) and successively scanning control channel signals of a base station being in service and peripheral base stations by a mobile station to measure reception qualities and selecting an optimum base station. CONSTITUTION:With respect to a mobile station 5, one of n-number of time slots is set to the communication state, and the other time slots are in waiting or stop states. Consequently, the mobile station 5 scans control channels of respective base stations during the waiting or stop state though performing communication. The mobile station 5 uses the intensity of electric field, BER(bit error rate) of data, or the like to measure the reception quality of each control channel and selects the best base station. |
