Problems solved by technology

Although these systems have the function of listening to the voice quality of the communication network, they can manually evaluate the voice quality of the communication network subjectively; but artificial listening and subjective evaluation of the voice quality ultimately depend on the subjective feelings of people, which is not only laborious and time-consuming, but also limited by various test conditions And the influence of subjective factors of the testers, so that the reliability of the measurement results is affected to a certain extent
Especially if you want to manually listen to the voice quality of a large number of detection points and make a unified evaluation in a short period of time, this is impossible

Embodiment 1

[0037] Embodiment 1. A mobile communication network remote detection system, as shown in FIG. 1, consists of a remote detector 100, a detection center platform 200, a coupler 300, a source device 400, a donor antenna 500, and a mobile communication wireless network 600 .

[0038] The remote detector 100 adopts the remote detector in the patent number 200520014554.3. As shown in FIG. 4, the remote detector 100 includes a housing 2, and an antenna 4 and a working status indicator light 6 are respectively provided on the housing 2; a mode setting switch 1 and a control processing unit 3 are respectively provided in the housing 2 And microphone and speaker interface 5. The control processing unit 3 includes: a watchdog module 30, a power-on reset module 31, a central processor 32, a power supply module 33, a data memory 34, a voice chip 35, a channel control chip 36, and a wireless communication module 37 with a built-in SIM card 38 The wireless communication module 37 can be a GSM...

Embodiment 2

[0071] Embodiment 2. A remote detection system for a mobile communication network. The selected remote detector 100 is shown in FIG. 5, and the central processor 32 of the remote detector 100 is also provided with a voice quality measurement component 700. The rest of the structure is the same as in Example 1.

[0072] That is, in the second embodiment, a voice quality measuring component 700 is provided in the central processor 32 and the detection center platform 200 respectively.

[0073] Therefore, the above-mentioned detection system is used to remotely detect the call quality of the output signal of the mobile communication source device 400:

[0074] 1. When detecting (called or calling) uplink voice quality, the same as in embodiment 1.

[0075] 2. When detecting downlink voice quality, perform the following steps in sequence:

[0076] 1. The test center platform 200 sends out a voice signal (standard test voice recommended by the ITU or a typical ordinary voice), which is tran...

Embodiment 3

[0078] Embodiment 3, a mobile communication network remote detection system, as shown in FIG. 6, consists of a remote detector 100, a detection center platform 200, and a mobile communication wireless network 600. The remote detector 100 is the same as in Embodiment 1, as shown in FIG. 4.

[0079] Therefore, the difference between Embodiment 3 and Embodiment 1 is that the coupler 300, the source device 400 and the donor antenna 500 are eliminated. Therefore, in Embodiment 3, the antenna 4 on the remote detector 100 is directly connected to the mobile communication wireless network 600. The rest is equivalent to Example 1.

[0080] When using the above detection system to remotely detect the call quality of the mobile communication network signal, the antenna 4 directly transmits the signal to the mobile communication wireless network 600; thereby replacing the “antenna 4 passing through the coupler 300 and the source device in turn in the first embodiment. 400. The donor antenna ...

Abstract

The present invention discloses a mobile communication speech quality remote inspection system. The present invention comprises an inspection central platform (200) and a remote inspector (100) with an antenna (4), and the remote inspector (100) is connected with the inspection central platform (200) through an inspected system; a voice quality inspecting component (700) is arranged in the inspection central platform (200), and a voice quality inspecting component of the voice MOS assessment software based on the PESQ algorithm is arranged in the voice quality inspecting component (700). The present invention also provides a method for performing the mobile communication speech quality remote inspection by utilizing the above inspection system, the method can perform inspection and assessment to the speech quality objectively and effectively, therefore to judge the running state of the signal source equipment or the communication network, and to sensing the feeling of the user during the mobile communication.

Description

Technical field [0001] The invention relates to a voice MOS evaluation system based on the PESQ algorithm, in particular to a mobile communication voice quality MOS evaluation system based on the PESQ algorithm in a mobile communication network remote detection system (ie, a mobile communication call quality remote detection system). Background technique [0002] At present, in the mobile communication operation network, there is a mobile communication call quality remote detection system (for example, a mobile communication network remote detector with a patent number of 200520014554.3 developed by myself) for remote detection of mobile communication network signals or mobile communication signals The output signal of the source equipment (repeater, trunk amplifier, BTS cellular). Although these systems have a listening function for the voice quality of the communication network, they can manually and subjectively evaluate the voice quality of the communication network; but the ...
