Problems solved by technology
Therefore, when the upstream load is too large, the upload queue will be congested, and the confirmation data cannot be sent, which will obviously affect the transmission speed of the confirmation message, and then affect the download rate.
[0003] However, in related technologies, it is only possible to analyze and determine the impact of bandwidth and application software on broadband speed measurement results, but the causal relationship between upload rate and download rate cannot be determined
This leads to the defect of incomplete analysis in the analysis of broadband speed measurement results in related technologies

The invention discloses a causal relationship identification method, a terminal device and a computer readable storage medium. The method comprises the steps: acquiring broadband transmission data, wherein the broadband transmission data comprises an upload rate time sequence and a download rate time sequence; determining a self-prediction error corresponding to the uploading rate time sequence based on an autoregression model, and determining a joint prediction error corresponding to the uploading rate time sequence based on a joint regression model and the downloading rate time sequence; or determining the self-prediction error corresponding to the downloading rate time sequence based on the autoregression model, and determining the joint prediction error corresponding to the downloading rate time sequence based on the joint regression model and the uploading rate time sequence; and determining a causal value between the uploading rate and the downloading rate according to the self-prediction error and the joint prediction error. The invention aims to achieve the effect of improving the comprehensiveness of broadband speed measurement result analysis.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method for identifying causality, a terminal device and a computer-readable storage medium. Background technique [0002] Due to the complex network environment, there are many factors that affect the broadband upload and download rates, such as the actual physical bandwidth, the current network environment, and the actual application software used. However, in a computer network, the transmitted resource needs to receive a confirmation message reply from the resource to determine the subsequent transmission rate and decide whether to retransmit the lost resource. Part of the uplink bandwidth is used to transmit these confirmation messages. Therefore, when the upstream load is too large, the upload queue will be congested, and the confirmation data cannot be sent, which will obviously affect the transmission speed of the confirmation message, and then affect the...
