A base transceiver station of a soft handover destination node does not perform control by using Hybrid Automatic Repeat Request, and a base transceiver station of a soft handover origin node sends data to a mobile node according to control performed by using Hybrid Automatic Repeat Request when the soft handover occurs. A radio network controller sends data destined for the mobile node only to the base transceiver station of the soft handover origin node. When the data is transferred from the base transceiver station of the soft handover origin node, the radio network controller transfers the data to the base transceiver station of the soft handover destination node. When a request to resend the data is received from the base transceiver station of the soft handover destination node, the radio network controller transfers the resend request to the base transceiver station of the soft handover origin node.
