Problems solved by technology

However, the data obtained in this patent is only used for MOS value evaluation, and to obtain user information and user location information to generate voice quality evaluation files, and it is also impossible to locate the root cause of voice quality problems
[0005] In general, the traditional method usually only evaluates the quality of VoLTE calls to judge whether the call quality is good or not or whether there is a problem with the call quality, but it cannot complete the precise positioning of VoLTE call quality problems, and manual analysis is still required to determine the problem location, the processing efficiency is slow, and it is not convenient for daily network operation and customer complaint handling
Therefore, in daily network operation and customer complaint handling, a method that can quickly locate VoLTE call quality problems is needed to support network development and user complaint handling, but the current existing technologies cannot provide effective support

Embodiment 1

[0060] Before introducing the method provided by the embodiment of the present invention, first, some common call quality problems in VoLTE calls and the main causes of the call quality problems are briefly introduced, so as to facilitate subsequent understanding of the automatic solution for VoLTE call quality problems provided by the embodiments of the present invention. delimited method.

[0061] VoLTE call quality problems are mainly manifested in three types: single pass, intermittent and double fail. One-way means that the calling party and the called party cannot obtain the real-time transport protocol (Real-TimetransPortprotocol, abbreviated as RTP) voice packet of the other party within a certain period of time (for example, more than 5s), resulting in the inability to hear the voice of the other party; Time-discontinuous packet loss leads to discontinuous RTP voice packets, voice distortion or word loss; double failure means that both the calling party and the called...

Embodiment 2

[0107] On the basis of the method for automatically demarcating the VoLTE call quality problem provided by the above-mentioned embodiment 1, the present invention also provides an automatic demarcation device for the VoLTE call quality problem that can be used to implement the above method, such as Image 6 Shown is a schematic diagram of the device architecture of the embodiment of the present invention. The apparatus for automatically demarcating VoLTE call quality problems in this embodiment includes one or more processors 21 and memory 22 . in, Image 6 A processor 21 is taken as an example.

[0108] The processor 21 and the memory 22 may be connected via a bus or in other ways, Image 6 Take connection via bus as an example.

[0109] The memory 22 is a non-volatile computer-readable storage medium as a method for automatically demarcating VoLTE call quality problems, and can be used to store non-volatile software programs, non-volatile computer-executable programs and ...

Abstract

The present invention relates to the field of communication technology, and specifically provides a method and device for automatically demarcating VoLTE call quality problems. Correlate the bill with the control plane bill to get the XDR associated bill; evaluate the call quality based on the user plane data in the XDR associated bill, if there is any call problem in the call, it will be evaluated as poor call quality; when the call quality When the call quality is bad, it will be judged step by step based on the call problem type and the user plane data and control plane data in the XDR related bill, and finally locate the cause of the poor call quality. This method can not only realize call quality evaluation, but also realize automatic demarcation of call quality problems, which is convenient for daily network operation and customer complaint handling, can reduce the workload of manual analysis, make up for the lack of experience of daily optimization personnel, and improve the efficiency of problem handling.

Description

【Technical field】 [0001] The invention belongs to the technical field of communications, and specifically provides a method and device for automatically demarcating VoLTE call quality problems. 【Background technique】 [0002] Voice over Long-Term Evolution (VoLTE for short) refers to a high-speed wireless communication standard for mobile phones and data terminals. With the rapid development of VoLTE users, user complaints have also increased. However, due to the complexity of the network structure, it is difficult to accurately delimit VoLTE problems only by relying on a certain professional. At present, the analysis of VoLTE call quality based on deep packet inspection (Deep Packet Inspection, abbreviated as DPI) technology has been widely used. By deploying the DPI collection system in the carrier network, the original data packets of VoLTE calls are collected, and then according to the The analysis of data packets is used to evaluate the voice quality. [0003] For exa...
