    • In a data communication system which reduces traffic on a wireless network by reducing Ack responses, on a transmitting side, an Ack request provided within a wireless data frame is validated (turned “ON”) to be transmitted; and an Ack request cycle is extended when an Ack in response to the Ack request has been received within a fixed time (timeout period “To”) during a cycle for transmitting the Ack request while if otherwise, the cycle is shortened. On a receiving side, only in case that a frame identifier indicating a sequence of an Ack request is found to be an expected one and the present Ack request receiving interval is found to be longer than the last Ack request receiving interval, a redundant transmission frequency of the Ack in response to the Ack request is decreased while the Ack request receiving interval is updated to the present interval in either case.
    • 在通过减少Ack响应减少无线网络上的业务的数据通信系统中,在发送侧,在无线数据帧内提供的Ack请求被验证(转为“ON”)以被发送; 并且在用于发送Ack请求的周期期间在固定时间(超时时间段“To”)内接收到响应于Ack请求的Ack时,延长Ack请求周期,否则周期缩短。 在接收侧,只有在发现表示Ack请求的序列的帧标识符被认为是期望帧的情况下,发现当前的Ack请求接收间隔比最后的Ack请求接收间隔长时,冗余传输频率 Ack请求的响应减少,而在任一情况下,Ack请求接收间隔被更新为当前间隔。

    • A wireless terminal and wireless communication method that can improve data transfer efficiency and reduce traffic. A frame transmitter of a wireless terminal transmits a frame by wireless. A wireless terminal receives the frame transmitted from the frame transmitter and transmits the received frame by wireless to a wireless terminal. A frame receiver receives the frame transmitted from the succeeding wireless terminal to the wireless terminal. When the frame is received by the frame receiver, a frame reception recognizer recognizes that the frame has been received by the succeeding wireless terminal. It is therefore unnecessary for the wireless terminal to receive, from the succeeding wireless terminal, a frame indicative of reception of the frame, so that the data transfer efficiency improves and the traffic reduces.
    • 一种可以提高数据传输效率和减少流量的无线终端和无线通信方法。 无线终端的帧发送器通过无线发送帧。 无线终端接收从帧发送机发送的帧,并通过无线将接收到的帧发送到无线终端。 帧接收器接收从后续无线终端发送到无线终端的帧。 当帧由帧接收器接收时,帧接收识别器识别出该帧已被接下来的无线终端接收。 因此,无线终端不需要从后续的无线终端接收指示帧的接收的帧,从而提高数据传输效率并减少流量。

    • A wireless communication apparatus on the receiving side receives communication data that is a transmitted to the wireless communication apparatus using one of the plurality of channels. Subsequently, the wireless communication apparatus on the receiving side obtains channel information contained in the communication data received by the receiving unit and judges whether the obtained channel information is target information indicating a channel of a processing target. The wireless communication apparatus on the receiving side performs a receiving process on the received communication data, when the judging unit determines that the obtained channel information is the target information, performs a receiving process on the communication data received by the receiving unit and that, when the judging unit determines that the obtained channel information is not the target information, discards the received communication data.
