Problems solved by technology

For the IP video service quality monitoring system, these operations of the user will cause various KPI parameters (such as video MOS, MPEG-TS layer packet loss and jitter) ) degradation and warning
However, since these alarms are caused by the operation behavior of IP video users, they do not correctly reflect the actual quality of user experience, so they belong to the category of false alarms

Embodiment 1

[0031] see figure 1 , the present invention discloses a method for improving the accuracy of an IP video media stream service quality alarm, said method comprising the steps of:

[0032] [Step S1] Carry out two-way data capture to the IP video unicast service flow through the acquisition device, and process the MPEG-TS media flow data and RTSP signaling data respectively; the IP video unicast service flow includes VOD or / and time Move the TV. For the processing of RTSP signaling data, go to step S2; for the processing of media stream data, go to step S3.

[0033] [Step S2] For the RTSP signaling data, perform message decoding analysis according to the RTSP protocol standard, and extract the KPI that will affect the media stream in the RTSP signaling (KPI refers to Key Performance Indicator, key performance indicator, which is another kind of QoS / QoE statistical parameters More commonly called) degraded command message events, and record these RTSP events Er and their samplin...

Abstract

The invention discloses a method and a system for improving the quality of service (QoS) alarming accuracy of an Internet protocol (IP) video media stream. The method comprises the following steps of: performing two-way data capturing on an IP video unicast service stream; for real time streaming protocol (RTSP) signaling data, performing message decoding and analysis according to an RTSP standard, extracting command message events degrading key performance indicators (KPI) of the media stream in RTSP signaling, and recording the RTSP events Er and sampling point positions thereof; performing message resolution on the data of the video media stream, and calculating all the QoS / quality of experience (QoE) statistical KPIs of each video media stream; performing alarming threshold detection on each statistical KPI in a current sampling period; and checking whether N sampling points before a current sampling point in the video media stream have the RTSP events Er or not, determining that video media stream KPI border-crossing events are video media stream KPI events caused by normal user behaviors if the N sampling points before the current sampling point have the RTSP events Er, otherwise determining that the video media stream KPI border-crossing events are alarming events for influence on QoE. By the method and the system, the QoS alarming accuracy of the IP video media stream of the system can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication testing, and relates to an IP video network detection method, in particular to a method for improving the accuracy of an IP video media stream service quality alarm; at the same time, the invention also relates to a method for improving the IP video media stream service quality alarm precision system. Background technique [0002] In recent years, with the rapid development of IP networks and applications and the increasingly intensified competition in the communication market, major telecom operators around the world are setting off an upsurge of IPTV network construction and triple play business development. Among the IPTV network services, VOD and time-shifted TV services are more and more popular, and gradually become the killer application of "triple play". However, because both VOD and time-shifted TV services use IP unicast technology to transmit video media streams, when many users ...
