When transmitting data from a data relay apparatus to a mobile station through a plurality of base stations, the plurality of base stations add sequence numbers to the data and transmits the data with the sequence number. The data relay apparatus transfers a first data and second data to the mobile station through different base stations among the plurality of base stations, in which the data relay apparatus transfers the first data received before the second data to one base station and transfers the second data while adding thereto information indicating the reception order of the first and second data. Each of the plurality of base stations, when the data transferred from the data relay apparatus contains the information added thereto, adds the sequence number to the data based on the information and transmits the data with the sequence numbers to the mobile station. |
