Right now

2G network has mature speech-evaluation system

that can objectively reaction user perception

and effectively locate and solve the problem of voice. However

4G network in which data services is the main is lack of perceptional evaluation

and 4G network problems involve the end-to-end network elements

with no effective way to locate. This paper mainly presents a evaluation method of 4G network users perception based on signaling analysis

and correspondingly presents locating processes of end-to-end network problem.
