| With the rapid development of the Internet,the network has affected many aspects of people’s life.In particular,the emergence of mobile Internet,people have begun to use mobile devices to access the network anytime and anywhere.With the continuous development of mobile communication technology,compared to the 2G network,The 3G network greatly improves the speed of accessing the network,which makes the expectations of network performance and service quality are also rising.Therefore,telecom operators need to provide reliable tools and means for the maintenance and analysis of the operation of the network,which can detect network problems and provide high-quality network services to users.In mobile networks,when user applications send or receive data,signaling messages will be triggered to initiate or release radio resources for the data transfer.However,massive signaling messages will increase the processing and transmission overheads of the cellular network infrastructure,and this in turns degrades the performance experience of mobile subscribers.This paper mainly focuses on 3G network to analyze the signaling packets,and study the user behavioral characteristics and quality of signaling link in current networks.In order to realize the analysis of signaling packets,first we need to parse and extract 3G network packets.Thus,we designed and implemented a signaling parsering and matching system to extract key information contained in the packets.The output of the system is the formatted data containing the key information and business processes information.Meanwhile,in order to visualize the quality of the current link and the base station from data analysis,we design and implementet a signaling quality analysis system.Both systems will provides effective support for quality monitoring of the current 3G network.Then,we analyzed the signaling packet and got the basic characteristics of the user’s online behavior and network quality.Therefore,the conclusion of this article can make contributions to network optimization and fault prevention.In the last chapter,this thesis gives a summary and outlook on signaling research in 3G mobile network. |
