A GTP Protocol Analysis System Of 4G Mobile Network

With the emergence of high-end smart terminals and the widespread use of 4G mobile networks,people are increasingly communicating through the mobile network.How to grasp the usage habits of people more clearly and accurately in large-scale mobile network big data becomes an important issue for operators.Therefore,it is particularly important to analyze the GTP protocol that carrying a large amount of user information in 4G LTE.Based on the background of 4G mobile Internet development,this paper summarizes the development status of 4G LTE both at home and abroad as well as the related 4G LTE technology principles.Based on the deep analysis of 4G EPC architecture,we establish the importance of GTP protocol that carrying a large amount of user information.So that we decided to design a GTP protocol analysis system.After analyzing the requirements of the system,the design ideas and implementation methods of the four modules of data acquisition,protocol analysis,data storage and user management are clarified.For example,the data acquisition module adopts zero-copy acquisition technology to speed up the acquisition of data packets.Protocol resolution The module realizes the key information extraction of GTP protocol according to the basic principle and the features of GTP protocol.The storage module realizes the effective storage of key information of GTP protocol and the management module realizes the comprehensive management of the system.Finally,by demonstrating the system integration test and system test results,it shows the actual effect of GTP protocol analysis system.
