摘要:
A packet transmission control device and a packet transmission control method for reducing degradation of system throughput due to a wireless mobile station in an abnormal state, in controlling transmission of packets to each of a plurality of wireless terminals. A channel is assigned based on an evaluated value from an evaluation function containing an average transmission rate value for the wireless terminal in its denominator, and if the evaluated value falls in an abnormal value, the average transmission rate value is initialized to reduce the frequency of assigning packets to the wireless terminal if one of multiple wireless terminals transitions to an abnormal state. By initializing the average transmission rate value, a phenomenon that an unnecessarily large number of shared channels are assigned to a wireless mobile station in an abnormal state may be avoided to prevent degradation of overall system throughput.
