Abstract:
1. A communication apparatus which communicates with a plurality of wireless terminals, comprising: an assignment order determination unit which is arranged to determine an assignment order of wireless channels between said communication apparatus and said wireless terminals based on a maximum stay time of data to be transmitted from a transmission end for every reception and for wireless terminal; and a wireless channel assignment unit which is arranged to assign, according to the thus-determined assignment order, the wireless channels between said communication apparatus and said wireless terminals, including a wireless terminal classification unit which is arranged to classify each wireless terminal into a first wireless terminal for which the maximum stay time of the data to be transmitted or the data to be received has exceeded a predetermined time, or a second wireless terminal for which the maximum stay time of the data to be transmitted or the data to be received has not exceeded the predetermined time; wherein, when said communication apparatus acts as the reception end, said assignment order determination unit is arranged to determine said assignment order based on the communication quality measured in the said communication apparatus for each wireless terminal, and the maximum stay time of the data to be transmitted measured in each wireless terminal and the measured result sent to the said communication apparatus; and, said assignment order determination unit is arranged to give priority for the first wireless terminals over the second wireless terminals to determine the assignment order therefor.
