摘要

针对目前评估VoLTE视频通话质量的方法的缺点，提出了一种基于机器学习和网络指标参数的VoLTE视频通话质量评估方法。首先，采集解码核心网的网络参数指标数据，并进行预处理；然后，选取用于VoLTE视频通话质量评估的关键特征，并通过对比选取合适的机器学习算法，构建VoLTE视频质量评估的评估模型，从而实现不依赖于测试环境和原始视频的VoLTE视频通话质量实时评估。通过对从XDR（用户话单）数据中提取的特征指标数据进行预处理研究，解决了特征指标的标准化问题，便于指标特征输入评估模型；通过特征工程选出评估VoLTE视频通话的关键特征，减少特征维数，从而降低了算法的复杂度；同时采用先进的机器学习技术保证和提升算法的评估准确性。

Abstract

To overcome the shortcomings of current methods for evaluating VoLTE video call quality

a method for evaluating VoLTE video call quality without reference based on machine learning and network index parameters was proposed.Firstly

the network parameters of the decoding core network were collected and preprocessed; then

the key features for VoLTE video call quality assessment were selected

and a reference-free evaluation model for VoLTE video quality assessment was constructed by comparing and selecting appropriate machine learning algorithms

so as to achieve real-time VoLTE video call quality assessment independent of the test environment and the original video.By researching the preprocessing of feature index data extracted from XDR data

the standardization of feature index was solved

and the evaluation model of feature input was convenient; the key features of VoLTE video call were selected and evaluated by feature engineering

which reduced the feature dimension and the complexity of the algorithm; at the same time

advanced machine learning technology was adopted to ensure and enhance the algorithm assessment accuracy.
