Abstract:

The relationship between user＇s perception and network performance index was studied.A five-element-five-phase (FEFP) method based on substitution between sample and space was proposed.Active operation and maintenance mode based on network performance management,can quickly find out the performance of the network in the imbalance between the nodes,abnormal trend of hidden problems etc with active network analysis.According to the analysis of the initiative,the engineers can target for exact optimization,reduce the costs,improve the quality of the network and customer satisfaction before the failure occurred.

Key words: mobile internet, big data, user perception, performance analysis, active maintenance, five element five phase, sample and space substitution
