Method for detecting voice relay passageway and equipment thereof

Abstract

The embodiment of the invention discloses a method for detecting a voice relay path, which comprises: performing a calling test on a specified relay device through a TCTDI instruction; acquiring relay data on the delay device according to the calling test; and analyzing the voice quality on the relay device according to the relay data. Correspondingly, the embodiment of the invention also discloses a device for detecting the voice relay path, which comprises a test unit, an acquisition unit and a quality analysis unit, wherein the test unit is used for performing the calling test on the specified relay device through the TCTDI instruction; the acquisition unit is used for acquiring the relay data on the relay device according to the calling test in the test unit; and the quality analysis unit is used for analyzing the voice quality on the relay device according to the relay data acquired by the acquisition unit. By implementation of the embodiment of the invention, different circuits under different local directions can be freely specified for testing.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for detecting a voice relay path. Background technique [0002] There are many standards for measuring voice quality. An obvious method is Mean Opinion Score ("MOS"), which allows evaluators to directly participate in voice calls and calculates the average score (1 -5 points, 5 points being the highest), so MOS is an evaluation standard for a subjective test, and its disadvantages are time-consuming, high cost and inconvenience. [0003] Therefore, the following objective evaluation methods are usually used: Perceptual Speech Quality Measure (PSQM for short), Perceptual Analysis Measurement System (PAMS for short), Perceptual Evaluation of Speech Evaluation (Perceptual Evaluation of Speech Quality, referred to as "PESQ"). Among them, PESQ is currently the most widely used in the industry and has always been considered the most accurate and reliable method. The o...

Problems solved by technology

However, in daily network maintenance, it is necessary to test multiple transmission paths downstream from the same office one by one, so as to timely detect hidden faults such as single-way, cross-linking, and quality degradation caused by quality problems of individual paths, especially those currently carried by TDM Today, with the development of IP bearer direction, it is more necessary to be suitable. However, this solution can only randomly select channels in the test, and cannot meet the daily maintenance needs.

[0006] Various existing technical solutions have the following defects: 1. Do not support testing of specific transmission channels; 2. Some of them are not suitable for existing mobile networks based on TDM bearer; 3. Some solutions need to add special hardware, which increases the cost
