Embodiment Construction
[0050] The present invention will be described in detail below in combination with specific embodiments.
[0051] A kind of VoLTE voice quality MOS evaluation method based on business terminal, specifically implement according to the following steps:
[0052] Step 1. Perform root operation on the mobile phone terminal containing Qualcomm chip. When performing root operation, use 360root master or SUroot tool to obtain system permissions;
[0053] Step 2. After step 1, use the virtual module in the mobile terminal to obtain the code stream of the Qualcomm chip terminal user plane. The virtual module is a mobile APP application program used to evaluate the quality of VoLTE voice information;
[0054] The process of obtaining the code stream of the Qualcomm chipset terminal user plane is as follows:
[0055]According to the Qualcomm chip interface protocol "IP Multimedia Subsystem (MS) Interface Control Document (CD) 80-NA365-7AApri23, 2012", fill the corresponding fields of the...

The invention discloses a VoLTE voice quality MOS evaluation method based on a business terminal. The specific operation steps are as follows: step 1, perform a root operation on a mobile terminal containing a Qualcomm chip to obtain system permissions; step 2, use a virtual module after step 1 Obtain the code stream of the terminal user plane of the Qualcomm chip, and the virtual module is used to evaluate the quality of VoLTE voice information; Step 3, after step 2, the virtual module decodes the code stream of the terminal user plane of the Qualcomm chip to obtain the transmission parameter R; Step 4, after step 2 After 3, calculate the MOS value of voice quality. The VoLTE voice quality MOS evaluation method of the present invention is simple to operate and easy to carry; problems can be dealt with in time, a mobile phone terminal can be operated at any time, and the mobile phone can be operated immediately when a problem occurs; the results can be checked in real time, which is convenient and quick.
Description
technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a VoLTE voice quality MOS evaluation method based on a business terminal. Background technique [0002] The test of voice quality has been using evaluation methods such as BER, FER (bit error, frame error) and frequency spectrum. Although this method is mature in technology and easy to operate, it is an indirect objective evaluation, and the evaluation principles of the voice quality of fixed-line telephones, walkie-talkies, radio stations, and mobile phones are different, so the comparability of the results (grades) Poor, and with the use of VOLTE business, there is still no efficient and accurate evaluation method and tool for VOLTE voice MOS. [0003] Voice quality assessment can be divided into subjective and objective assessments. [0004] First, the objective evaluation methods mainly include: PSQM, MNB, PSQM+, PAMS99, PESQ, etc. Objective speech assessmen...
