Method and device for improving video service perception

Abstract

The embodiment of the invention provides a method and device for improving video service perception. The method comprises the following steps: analyzing an uplink data packet which exceeds a preset threshold and is an HTTP GET packet; if the specific offset address of the uplink data packet contains the keyword and is matched with the dynamic video feature library, the video service identificationis successful; wherein the dynamic video feature library is preset and dynamically updated. The embodiment of the invention is based on video service keywords. Matching a keyword of a specific offsetaddress in an uplink data packet which exceeds a preset threshold and is an HTTP GET packet with a preset and dynamically updated dynamic video feature library; if matching succeeds, identification succeeds, the problem that wireless high-load scene video service perception is poor is solved, and after identification succeeds, parameters such as scheduling priority improvement, independent configuration of flow control and uplink pre-scheduling can be adopted to guarantee service perception.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication data services, and more specifically, to a method and device for improving video service awareness. Background technique [0002] At present, 4G networks have been widely used, and video services have also been widely promoted. The proportion of video services in network traffic is getting higher and higher. Nearly half of 4G users use online video services. [0003] Video service perception evaluation indicators are reflected in many aspects, such as the initial playback delay, the frequency of blurred screens and freezes, etc. The elements that affect video service perception are also related to many aspects, such as video playback terminal, wireless side and limited side transmission, video source quality, video server, etc. High-definition video requires high-speed data transmission. If there is a problem with video data transmission from the video server to the te...

Problems solved by technology

Continuous Z; the number of large packets exceeding 1000 bytes received in period T is less than the threshold C, and the user is considered to have quit the video service, but there are misjudgments based on service traffic or rate identification, such as FTP downloads, large email downloads, and large web pages download

The duration of the webpage is not long. By increasing the detection cycle, some such services can be excluded and the accuracy of video service recognition can be increased. However, the disadvantage of this is that the service recognition time is long, and the video service indicators cannot be effectively improved: the initial buffering time also varies with the time. The influence of video service perception
