Abstract:

With the signaling data of LTE signaling monitoring system，the integrity，standardization and accuracy of XDR data are checked to improve the quality of XDR data and  to  perfect the bounding method for perception problem,such as integrated service low rate and poor quality residential areas，frequent ping-pong TAU problem，poor quality of internet element.This method can improve the accuracy of problem demarcation and location.The quality analysis and optimization of high-speed railway communication network is taken as an example.The support ability of the signaling data is extended in the analysis and application of the end-to-end service perception quality improvement.The end-to-end optimization results show that users' perceived quality indicators can be continuously improved.

Key words: user perception；mobile data, end-to-end；quality optimization
