Abstract

Provided is a radio communication system in which a radio communication between a first radio base station and a terminal may be replaced by a radio communication between a second radio base station and the terminal by a handover. The first radio base station includes a data packet creation unit which creates a dummy packet for a packet which has not been delivered and for which no delivery acknowledgement is received among transmission packets transmitted from the terminal to the first radio base station when transferring data remaining in the first radio base station to the second radio base station and creates a data packet containing the dummy packet; and a transfer unit which transfers the created data packet to the radio base station as the handover destination. The second radio base station includes a data packet reception unit which receives the data packet, and an undelivered packet reception unit which requests the terminal to transmit the undelivered packet and receives the undelivered packet from the terminal.
