A base station transmits service data to a terminal at a first transmission rate. A server transmits the service data to the base station at a second transmission rate required for transmitting the service data. When the second transmission rate exceeds the first transmission rate, the server determines a part of the service data by thinning out the service data so that the part is able to be transmitted to the terminal at the first transmission rate. The server provides the determined part with marking information, and transmits the service data provided with the marking information to the base station at the second transmission rate. The base station extracts the part from the received service data based on the marking information provided for the part, and transmits the extracted part of the service data to the terminal at the first transmission rate. |
