A radio access network device performs communication with a mobile station by using an uplink-occupying channel, a downlink-sharing data channel, and a downlink signaling control channel. The radio access network device includes: uplink-occupying channel allocation means which allocates an uplink-occupying channel to a mobile station which is starting or resuming a communication by using the uplink-occupying channel, on the downlink-sharing data channel; occupied-channel reception detection means which detects a reception of the uplink transmission from the mobile station on the occupied channel which has been allocated; and the downlink transmission means which transmits a response to the mobile station by using the downlink-sharing data channel and the downlink signaling control channel if a reception of the occupied channel of the mobile station is detected. |
