Embodiment

[0030] Such as figure 1 As shown, a method for 2G3G4G voice quality fault four-domain six-dimensional intelligent demarcation described in this embodiment includes the following steps,

[0031] Step 1: Establish four domains for defining poor voice quality and six dimensions that affect voice call quality. Among them, the four domains include the core domain, access network domain, network transmission domain, and peer domain, and the six dimensions include voice MOS value, Call drop, crosstalk, one-way, word swallowing and intermittent;

[0032] Step 2: Calculate / assess the voice MOS value;

[0033] Step 3: Slice and analyze voice quality and present it with visualized waveforms.

[0034] In the step 2, first extract the key data of voice quality from the collected media information of each interface, such as voice coding mode, packet loss rate, delay value, jitter value, etc., using the E-Model algorithm of G.107 standard , to calculate the voice quality related parameter...

Abstract

The invention discloses a 2G3G4G voice quality fault four-domain six-dimensional intelligent delimiting method, which comprises the following steps: 1, establishing four domains for defining poor voice quality and six dimensions for influencing voice call quality, wherein the four domains comprise a core domain, an access network domain, a network transmission domain and an opposite-end domain, the six dimensions comprise a voice MOS value, a dropped call, a crosstalk, a single pass, a swallowing word and a discontinuous call; 2, calculating / evaluating the voice MOS value; 3, performing sliceanalysis on the voice quality, and presenting the voice quality by adopting a visual waveform. By adopting the method, the graph of the voice service quality can be seen, the visualization mode display of the voice fault can be achieved, and the delimiting and positioning of the voice quality can be quickly and effectively achieved.

Description

technical field [0001] The invention relates to the technical field of telecommunication operation support, in particular to a method for intelligently demarcating 2G3G4G voice quality faults in four domains and six dimensions. Background technique [0002] With the popularization of 4G services, the number of calls between 4G VoLTE users and 2G / 3G users is increasing. At the same time, there are more and more voice quality complaints about VoLTE and 2G / 3G calls. Therefore, it is necessary to solve VoLTE users and 2G / 3G users. Voice complaints between 2G / 3G users, and analyze the voice quality of 2G / 3G / 4G intercommunication. Traditional signaling plane monitoring cannot solve voice quality faults during calls, such as single-pass and intermittent calls, transmission delay, jitter, and packet loss. It is necessary to analyze voice quality in combination with media monitoring. [0003] Traditional 2G / 3G / 4G voice call fault diagnosis is based on separate analysis of signaling ...
