First Claim
Patent Images
1. A Quality of Service (QoS) control system used for a radio transmitter/receiver, comprising:
- a QoS control unit for supplying a modulator of said radio transmitter/receiver with transmission data in an order taking QoS into consideration; and
a determining unit connected to said QoS control unit for determining whether a QoS control operation of the transmission data is reguired or not in accordance with information transmission conditions in an associated radio path,wherein the QoS control operation of the transmission data by said QoS control unit is performed selectively in accordance with the information transmission conditions in the radio transmission path, andwherein said QoS control unit has a first operation mode for outputting the transmission data in an order of input and a second operation mode for outputting the transmission data in the order taking QoS into consideration, said first and second operation modes being switchable to each other in accordance with the information transmission conditions in said radio path.

Abstract
A radio transmitter/receiver having a QoS control unit for outputting the transmission data in order taking the quality of service (QoS) into consideration. In the case where the information transmission rate for a radio section is not lower than a threshold value, the QoS control operation of the transmission data is omitted, and the transmission data are output in the order of input. In the case where the information transmission rate for the radio section is lower than the threshold value, on the other hand, the QoS control mode is switched in accordance with the information transmission rate for the radio section.

9. A Quality of Service (QoS) control system used for a radio transmitter/receiver, comprising:
-
a QoS control unit for supplying a modulator of said radio transmitter/receiver with transmission data in an order taking QoS into consideration; and a determining unit connected to said QoS control unit for determining whether a QoS control operation of the transmission data is required or not in accordance with information transmission conditions in an associated radio transmission path, wherein the QoS control operation of the transmission data by said QoS control unit is performed selectively in accordance with the information transmission conditions in the radio transmission path, wherein said QoS control unit has a plurality of QoS control modes, wherein a QoS control mode to be applied to the transmission data is switched between said plurality of said QoS control modes in accordance with an information transmission rate for said radio transmission path, wherein said QoS control unit has a classification table showing correspondence between a class and a specific QoS control mode of said QoS control modes, wherein said classification table defines a class of each transmission data corresponding to a value of specific header information contained in the transmission data, and wherein said QoS control unit determines the class of the transmission data in said specific QoS control mode with reference to said classification table.

10. A Quality of Service (QoS) control method for a radio transmitter/receiver, comprising:
-
a first step of determining whether QoS control of transmission data is required or not in accordance with information transmission conditions in an associated radio path; a second step of supplying the transmission data to a modulator of said radio transmitter/receiver in an order taking QoS into consideration if QoS control operation is required; and a third step of supplying the transmission data to a modulator in an order of input if said QoS control operation is not required, wherein said second step includes the steps of; determining a class of each transmission data, setting the transmission data in a class-wise queue corresponding to a determined class, and reading the transmission data from said class-wise queue in accordance with a class-wise band assignment table with a guaranteed band set for each class.
