Problems solved by technology
First of all, the interaction between terminal hardware and operating system is relatively frequent, which increases terminal power consumption
Secondly, the detection of the amount of data accumulated in the buffer and the reporting of AT commands require the cooperation of the chip, which requires high chip requirements. However, most of the chips produced by manufacturers currently do not support the above functions, and their scope of use is limited.

Embodiment Construction
[0039] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the present invention.
[0040] The inventor of the present application found in the process of filing the present application that the prior art proposes a data transmission control scheme based on the MAC layer. like figure 2 , In the process of data transmission, the modem can be used to detect the accumulation of data in the chip buffer. When the data accumulation amount exceeds the preset threshold, a congestion alarm can be reported to the congestion control module through an AT command. Correspondingly, after receiving the congestion alarm, the congestion control module adjusts the data transmission rate. But in practice, it is found that there are at least the following three problems:
[0041] First, the interaction between the terminal hardware and the operating system is frequent, which increases the power co...

The embodiment of the present invention discloses a data transmission method, device, and computer storage medium, wherein the method includes: encoding and encapsulating the data stream to be transmitted, so as to obtain the data frame to be transmitted; determining the congestion indication of the data queue in the transport layer information, the data queue is used to arrange the data frames to be transmitted, and the congestion indication information is at least used to indicate whether data congestion occurs in the data queue; according to the congestion indication information of the data queue, the to-be-transmitted Data frames for transmission control. By adopting the embodiment of the present invention, data congestion can be discovered in time, combined with the congestion management mechanism of the data queue, the transmission delay of data frames and the packet loss rate of important data can be reduced when data congestion occurs; Rate to reduce the length of the data queue, and reduce the transmission rate of data frames to reduce the probability of data congestion again, thereby improving the real-time performance of data transmission.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a data transmission method, device and computer storage medium. Background technique [0002] During the communication process, due to the influence of factors such as terminal power, occlusion, base station deployment, signal weakening, multipath interference, etc., it may lead to problems such as poor transmission channel quality, large fluctuation of transmission channel bandwidth, or even insufficient bandwidth. prone to network congestion. In particular, for mobile video calls that are widely used at present, the uplink channel is easily affected, resulting in insufficient bandwidth of the uplink channel, and problems such as video freezes and unsmoothness, which affect the quality of the video call. like figure 1 , which shows a schematic diagram of the curve of the uplink channel bandwidth and the change of data transmission with time. [0003] In ...
