Embodiment Construction

[0059] The basic idea of ​​the present invention is: by saving the SNR (Signal-to-Noise Ratio, signal-to-noise ratio) value or CQI (Channel Quality Indicator, Channel Quality Indicator) value reported by the mobile terminal, and the SNR or CQI obtained in a period of time The mean value, smoothing and creating the mean value of SNR or CQI, makes the mean value of SNR or CQI more suitable for the actual situation of the current wireless environment quality, combined with the change of the buffer remaining amount of the local network element and NodeB buffer, the value of the data that can be sent or transmitted The block size is corrected, the data volume sent to the mobile terminal is adjusted in real time, and the data volume sent by the server to the local network element is adjusted by sending a control message to the server, so as to solve the problems existing in the prior art.

[0060] In order to make the object, technical solution and advantages of the present invention...

Abstract

The invention discloses a method and a communication device for adjusting transmission control protocol data transmission, which are used to solve the problem that the existing technology cannot adjust the data volume and transmission between the server and the communication device and the communication device and the mobile terminal in real time according to the change of the wireless transmission environment. The block size cannot dynamically adjust the technical defect of the transmission bandwidth. The present invention accurately adjusts the amount of data sent to the mobile terminal according to the real-time change of wireless transmission quality, so as to reduce data loss and error in wireless transmission, reduce the amount of data retransmission, and use wireless bandwidth with maximum efficiency; the present invention combines wireless transmission quality Changes are fed back to the transmission between the server and the communication device in real time, and the amount of data sent by the server to the communication device is adjusted in time to reduce unnecessary data loss due to buffer overflow of the communication device, thereby reducing data retransmission between the server and the communication device , making the most efficient use of transmission resources.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and a communication device for adjusting transmission control protocol (Transfer Control Protocol, TCP) data transmission based on changes in wireless signal quality. Background technique [0002] Due to the problems of long delay in wireless transmission, deterioration of the wireless transmission environment, handover, etc. leading to packet loss, it will trigger TCP congestion control, resulting in low TCP performance. Therefore, many manufacturers provide TCP proxy functions to shield the server from the transmission characteristics of the wireless environment. The difference is that the data is cached by the local network element, and the data is sent to the client as fast as possible according to the quality of the air interface, maximizing the use of the wireless transmission bandwidth. [0003] Such as figure 1 As shown, the TCP proxy functions curren...
