Wireless communication apparatus and wireless channel assignment method
First Claim
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, includinga 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.

Abstract
At each wireless terminal, a receiving unit receives a signal transmitted from a wireless base station. A signal-to-noise ratio measurement unit measures an S/N of this received signal. In the wireless base station, data amount measurement unit measures the amount of data stored in each buffer therein. A maximum stay time measurement unit measures a maximum stay time of packets in each buffer. A classification by the maximum stay time unit classifies each wireless terminal based on the maximum stay time. A slot assignment priority order determination unit determines an assignment order of time slots to each wireless terminal based on the classification result in the classification unit, the receiving signal-to-noise ratio, the amount of data, and the maximum stay time.

7. A method of assigning wireless channels in a communication apparatus which communicates with a plurality of wireless terminals, comprising:
-
a) determining 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 wireless terminal, and the communication quality at a reception end for every wireless terminal; and b) assigning, according to the thus-determined assignment order, the wireless channels between said communication apparatus and said wireless terminals, that when said communication apparatus acts as the reception end, said step a) includes a step of determining the assignment order of the wireless channels based on the communication quality measured in said communication apparatus for each wireless terminals, 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 c) classifying each wireless terminals 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, said step a) includes the steps of giving priority for the first wireless terminals over the second wireless terminals to determine the assignment order. - View Dependent Claims (8, 9, 10, 11, 12)
