Embodiment 1

[0028] This embodiment provides a general data acquisition platform and a data acquisition process based on the data acquisition platform for network operators to evaluate the construction method of a standard data set suitable for encrypted video QoE, figure 1 It is a schematic diagram of the network topology of the data collection platform of this embodiment. Such as figure 1 As shown, the mobile terminal can access the mainstream video website in two ways: (a) by means of a VPN proxy, use the mobile terminal A1 to pass through the VPN proxy server A3, and then through the switch A5 and the HTTP server A7 to access the mainstream video website; (b ) through the wireless routing of the local area network, using the mobile terminal A2 to access the mainstream video website through the wireless routing A4, and then through the switch A5 and the HTTP server A7. In the process of watching the video, network data, terminal video playback status and user MOS score data are activel...

Embodiment 2

[0034] This embodiment provides data analysis and construction of a standard data set for a method for constructing a standard data set for evaluating encrypted video QoE by a network operator. image 3 It is a schematic diagram of the data analysis process in Example 2. Such as image 3 As shown in , on the basis of obtaining network data and terminal playback logs in Example 1, the network data is analyzed to obtain QoS parameters and synchronized with the playback logs to construct a standard experimental data set.

[0035] Network data D2 is passed figure 1 The network data based on the TCP / UDP protocol obtained by the data collection platform is saved as a file in PCAP format. The PCAP file format is a network packet storage format supported by Wireshark, which contains all network data during a video viewing process. The video playback log D1 is the log automatically recorded and uploaded by the terminal APP in Embodiment 1, including your video playback status, user ...

Abstract

The invention discloses a construction method of a standard experimental data set for evaluating encrypted video QoE. The construction method of the standard experimental data set for evaluating the encrypted video QoE is characterized in that a general data acquisition platform is constructed, and the video network data, the video QoE parameters and the user MOS score of a mobile terminal in theprocess of watching the video can be collected at the same time in a single point of a HTTP server through the coordination between a terminal application and the HTTP server, so that the constructionof the standard data set is realized. Because the invention adopts a data acquisition mode combining a distributed feedback path test terminal with the VPN centralized mode and a standard data set construction method based on data flow, therefore, the data acquisition with a mass-packet mode can be conveniently supported by the invention; and the invention is suitable for encrypted and unencrypted video services based on TCP and UDP protocols, and the constructed data set is real and comprehensive, and has good completeness, therefore, the shortages of the data set construction method in theprior art is overcome.

Description

technical field [0001] The invention belongs to the technical field of mobile communication networks, and in particular relates to a method for constructing a standard data set for mobile network operators / equipment vendors to perform encrypted video QoE evaluation. Background technique [0002] Providing good user experience and guarantee is the starting point of operators' network optimization, and mobile network operators / equipment vendors are paying more and more attention to the evaluation of mobile video service quality. In recent years, with the popularity of 3G / 4G networks, mobile network video has developed rapidly. According to Cisco's 2016 statistical forecast, the traffic generated by mobile video services will account for more than 75% of mobile traffic by 2021. The current mainstream mobile video service is based on HTTP Adaptive Stream (HTTP AdaptiveStream, HAS). However, as people attach importance to user privacy, more and more content providers begin to e...
