Problems solved by technology

[0006] Although the average subjective test is accurate and effective, the biggest problem with this subjective method is that in reality, it is very difficult and expensive for a group of people to listen to the speech and evaluate the quality of the speech. This ideal test effect is usually only available in You can only experience it when you open the experimental bureau
[0007] Under the existing mobile communication technology conditions, commercial testers judge the quality of the network based on the transmission and reception of voice reference signals, which cannot effectively simulate the real environment in real time to achieve on-site listening and real experience
Therefore, operators and developers usually have to open experimental bureaus and use the MOS method for actual verification, but it requires huge financial and manpower

Embodiment Construction

[0034] In order to deeply understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as figure 1 Shown, the heavy traffic test environment of the present invention comprises mobile core network, PSTN (Public Switched Telephone Network, public switching telephone network), real RNC (radio network controller), is used to produce the sound source terminal of real voice, uses It is a detection terminal for listening to the voice signal of the audio source terminal, and a large traffic tester equipped with several analog terminals and analog RNC, wherein, PSTN and real RNC can be selected or exist at the same time, and the audio source terminal is mobile phone A, The detection terminal is mobile phone B.

[0036] In principle, the large traffic tester is an analog RNC, which is implemented by a digital signal processor and a communication processor, and a large numb...

Abstract

A method for odd-testing voice quality of large telephone traffic at mobile core network includes calling relevant analog terminal in large telephone traffic test center by sound source terminal and detection terminal separately and holding on communication state, holding on communication state between said relevant analog terminals and broadcasting real voice signal from sound source terminal to the other analog terminals at controller side of analog radio network as well as selecting a broadcasted analog terminal to carry out semi fixed chaining and unchaining to analog terminal connected with detection terminal repeatedly and randomly till add-test of voice quality is finalized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a voice sampling test method and a device thereof under heavy traffic of a mobile core network. Background technique [0002] At present, various commercial high-traffic performance testers are widely used in the high-traffic test of the mobile core network. In principle, these commercial testers are all simulated RNC (Radio Network Controller, radio network controller) equipment, used to simulate the control plane and user plane functions of the simulated RNC, provide an interface with the mobile core network, and realize the large traffic test function. Among them, the voice quality test of the user plane is realized by using the integrated standard algorithm, that is, using the wave file (Wave File) generated by the computer, and calculating the corresponding level and degree of quality in the standard by comparing the changes before and after its transmission through the n...
