Method for evaluating QoE (Quality Of Experience) of voice service user perception experience by simulating user behaviors

Abstract

The invention discloses a method for evaluating QoE (Quality Of Experience) of voice service user perception experience by simulating user behaviors. The method comprises the following steps of: firstly, setting a voice service QoE evaluation index system including perception experiences of a calling party and a called party, wherein the two types of user perception experiences are divided into experience parameters in three aspects of service access, service continuance and service completion; secondly, simulating the whole process of calling and being called of users using voice services by a test terminal, respectively acquiring and calculating key performance indexes (KPI) of the two voice services of calling and being called of the two parties of communication, calculating corresponding key quality indexes (KQI), and performing comprehensive operation on the parameters by means of a psychological model in combination with the KQI to obtain corresponding key experience indexes (KEI); and then comprehensively analyzing the KEI indexes to obtain a voice service QoE value which is in a five-grade marking system and equivalent to an international standard MOS (Mean Opinion Score). The method disclosed by the invention is objective and practicable in evaluation parameter standard, simple in operation procedure, low in calculation complexity and easy to implement, and can be used for obtaining relatively objective and just user experience perception quality by simulating the user behaviors.

Description

technical field [0001] The present invention relates to a method for evaluating the QoE (Quality of Experience) of a voice service in a mobile communication network. Specifically, it relates to a method for evaluating the perceptual experience of voice service quality using an objective method to simulate user behavior, which belongs to mobile communication The technical field of network service quality assessment. Background technique [0002] With the continuous development and popularization of mobile communication networks, users' requirements on the voice service quality of mobile communication networks are also increasing; it can be said that the quality of voice directly affects the user's choice of operators. Therefore, according to the service quality requirements of mobile communication networks, it is urgent to establish an objective evaluation system for voice service quality and user perception experience, so as to better conduct quantitative analysis and evalua...

AI Technical Summary

Problems solved by technology

[0010] Although some of the above-mentioned multiple voice service quality evaluation schemes are simple to implement and have perfect technologies, they cannot truly simulate the process of users using voice services, and cannot objectively reflect the different experiences of the calling and called users on the same voice service.

In a word, although the prior art has proposed several evaluation schemes for voice service quality and user experience, some of which are simple to operate and relatively perfect in technology; however, none of these techniques can really simulate the whole process of users using voice services. It cannot objectively reflect the user's experience perception evaluation of the whole process of the voice service
