Abstract

The embodiment of the present application discloses a voice quality assessment method, which relates to the field of communication technology and is invented to solve the problems existing in the prior art that the voice quality of the network cannot be assessed in real time and the accuracy of the assessment result is poor. The method is applied in a VoWiFi scenario. In a VoWiFi scenario, a calling terminal accesses a WiFi network and initiates a call through the WiFi network, and a called terminal accesses a call through a cellular network. The method includes: acquiring the signal strength of the WiFi network accessed by the calling terminal when the calling terminal initiates a call. Obtain the received signal strength when the called terminal accesses the call through the cellular network. The voice quality evaluation result of the call is determined according to the signal strength of the WiFi network accessed by the calling terminal when the calling terminal initiates the call, the received signal strength when the called terminal accesses the call through the cellular network, and a preset evaluation model.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a voice quality assessment method and device. Background technique [0002] At present, operators have gradually launched voice over Wi-Fi (VoWiFi) services based on Wi-Fi (voice over Wi-Fi, VoWiFi) across wireless-fidelity (Wi-Fi) and cellular networks through the operator's core network to make up for The user's demand for voice calls. In order to continuously improve VoWiFi services, it is necessary to evaluate the voice quality of VoWiFi. [0003] In the prior art, methods for evaluating voice quality mainly include subjective voice evaluation methods and objective voice evaluation methods. Among them, the subjective voice evaluation method needs to obtain the source voice and the test voice, and manually compare the source voice and the test voice to determine the final voice quality. This method cannot evaluate the voice quality of the network in real...
