<P>PROBLEM TO BE SOLVED: To implement accurate traffic suppression between devices inside a radio network in cooperation with an AMR function. <P>SOLUTION: A communication control unit 5 measures a flow rate of traffic flowing in a layer-2 switch 3 and stores it in an RAM 6. As the flow rate of traffic, flow rates in directions from a wireless line termination 2 to a wireless line termination 4, from the wireless line termination 4 to the wireless line termination 2, from the wireless line termination 2 to a wired line termination 8, from the wired line termination 8 to the wireless line termination 2, from the wireless line termination 4 to a wired line termination 8 and from the wired line termination 8 to the wireless line termination 4 are subjected. Furthermore, a value obtained by multiplying an average value of traffic flowing for T seconds by 1.2 is defined as a traffic flow rate. On the basis of the traffic flow rate, the communication control unit 5 detects a radio section in which a radio modulation system by an AMR function is changed. If it is necessary to change the modulation system, the modulation system is changed in accordance with a band change situation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
