The frequencies used by 0 to 3 are notified. At this time, the server A notifies all the base stations B-0 to B-3 of the same information. This allows the base stations B-0 to B-3 to know the frequencies used in other base stations.

Next, the operation of the base station B-0 will be described. The server data receiving unit 1 provided in the base station B-0 receives the downlink frequency information notified from the server A. Then, the server data receiving unit 1 stores the received information in the memory 2

Store in 14.

Next, the demodulation section 12 judges whether or not the signal can be received using the reception frequency 14b stored in the memory 14 (step S7), and if the signal can be received, the signal is received. The signal is demodulated and passed to the received signal analysis unit 13.

Is determined (step S9). This judgment is based on the fact that the received upstream frequency is RO
Whether or not transmission is possible is determined by whether or not the plurality of transmission-permitted frequencies 17b stored in M17 match. As a result, when transmission is possible, the determination unit 18 stores the upstream frequency in the memory 14. Then, the modulator 1
9 uses the transmission frequency 14a stored in the memory 14 to transmit the registration request for the mobile station C (step S5).

Next, if the signal cannot be received in step S7 and if the upstream frequency is not the permitted frequency in step S9, the operations of steps S6 to S9 are repeated (step S10).

Next, in step S10, if there is no other downlink frequency candidate, the selecting unit 15 reads the reception permission frequency 17a stored in the ROM 17, and the priority setting unit from the read reception permission frequency. The reception permission frequency is selected according to the priority order stored in 16 (step S11), and the reception permission frequency is stored in the memory 14.
