Communication Apparatus And Communication Control Method

Abstract: A communication device and a communication control method which can control a transmission rate of information such that a bandwidth is not exceeded at all times are provided. There are included: a reception means for receiving an input signal, and outputting received data; a transmission means for accepting a transmission frame, transmitting a transmission signal at a first transmission rate set based on transmission control information, and outputting a transmission timing signal indicating completion timing of transmission of the transmission signal; an information extracting means for extracting the transmission control information from the received data, and designating a second transmission rate when transmitting the next transmission frame to the transmission means; and a service quality control means for changing, upon detecting a second transmission rate being smaller than the first transmission rate, an upper limit transmission rate to the second transmission rate or less, changing, upon detecting a second transmission rate being larger than the first transmission rate, the upper limit transmission rate to the second transmission rate or less after the completion timing, and generating the transmission frame from transmitted data based on the upper limit transmission rate.
