A session video service QoE-QoS parameter mapping method based on statistical analysis

Abstract

The invention belongs to the field of QoE and network resource management of video services, in particular to a statistical analysis-based QoE-QoS parameter mapping method for a session video service,which comprises the following steps of firstly, capturing a video data stream in a required network through network packet analysis software in data acquisition, and storing the captured original data stream in a standard text format; secondly, carrying out a large amount of flow statistical characteristic calculation; then, calculating an MOS value according to the standard of the internationaltelecom alliance; selecting parameters such as packet loss rate, transmission rate, delay jitter and the like to perform graph drawing and formula fitting, and obtaining an optimal parameter suggestion index according to a result; and finally substituting the given reference value into the model for calculation, and carrying out statistics on the probability of falling in a preset MOS value rangefor verification. On the premise of guaranteeing the user experience quality, the network resources can be distributed more reasonably and effectively, and the resource waste caused by the excessive distribution of the network resources to the users with the user experience quality meeting the requirement is avoided.

Description

technical field [0001] The invention belongs to the field of QoE and network resource allocation, in particular to a QoE-QoS parameter mapping method for session video services based on statistical analysis. Background technique [0002] With the rapid development of computer networks and communication technologies, network multimedia services are playing an increasingly important role in people's lives, permeating every aspect of daily life. There are many kinds of multimedia business applications, such as video, medical treatment, online shopping, monitoring, teaching and so on. Among them, conversation streams in the form of video conversations, webcasts, 2D and 3D large-scale games are developing particularly rapidly. With the development of the economy and the Internet in the future, the market share of video conversations will continue to grow. How to allocate network resources more reasonably and efficiently on the premise of ensuring the quality of user experience i...
