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-consum

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 Patent No. 200520014554.3. As shown in Figure 4, the remote detector 100 includes a housing 2, on which an antenna 4 and a working status indicator light 6 are respectively arranged; a mode setting switch 1 and a control processing unit 3 are respectively arranged in the housing 2 and microphone and speaker jacks5. The control processing unit 3 includes: a watchdog module 30, a power-on reset module 31, a central processing unit 32, a power supply module 33, a data memory 34, a voice chip 35, a channel control chip 36, a wireless communication module 37 with a SIM card 38 inside , this wireless communication module 37 can be GSM communication mod...

Embodiment 2

[0071] Embodiment 2. A remote detection system for a mobile communication network. The selected remote detector 100 is shown in FIG. All the other structures are 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 in 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, it is the same as embodiment 1.

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

[0076] 1. The detection center platform 200 sends out a voice signal (standard test voice recommended by the ITU or typical common voice), which is transmitted to the remote end through the mobile communication wireless network 600, the donor antenna 500,...

Embodiment 3

[0078] Embodiment 3. A mobile communication network remote detection system, as shown in FIG. 6 , is composed 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 that in Embodiment 1, that is, 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 are equal 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; 400. The donor antenna 500 transmits the signal to the mobile communication wireless network 600". In the same way, the...

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 PESQ algorithm, in particular to a mobile communication voice quality MOS evaluation system based on 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 remote detection system for mobile communication call quality (for example, a mobile communication network remote detector developed by me with a patent number of 200520014554.3) for remote detection of mobile communication network signals or mobile communication signals. The output signal of the source equipment (repeater, trunk amplifier, BTS cell). 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 ...
