The Implementation And Application Of GTP Protocol Analysis System

With the rapid development of GPRS network services, the mobile internet users are increasing year by year, this pushes the GPRS network operators to put much more energy and investment into the building of network constructions. As a transition solution for the evolution from2G to3Q the security and performance of GPRS network have paid more and more attentions.In order to maintain and optimize the mobile network, many operators are eagerly required to do the monitoring and analyzing network data more effectively. Once the operators have established a reliable network monitoring system, it is not only convenient to achieve the accurate collections of the data on mobile internet, but also valuable to help operators finding out the law of mobile users’behavior, analyzing the qualities parameters of current network, and finally enhance the quality of network service. In addition, through the establishment of comprehensive network monitoring system, operators are not only able to meet the customers’ demand for wireless access services, but also can fully tap the service preferences of the mobile user. So better service can be provided for customers, and more valuable marketing strategies can be used by operators. With the long-term existence of win-win situation that the service provider are continuing improving their profits while the mobile users are enjoying much better service, there will be much more rapid development of the mobile communications industry in China.This thesis mainly discusses the implementation and the application of a monitoring system which based on the GTP protocol analysis. Firstly, the importance of signal data monitoring is emphasized, and then the GPRS network architecture and its protocols are also described. In second part of this article, a detailed discussion on GTP protocol is given, after that, the solution based on analyzing the GTP control plane protocol are presented. In third part of this article, the details of the implementation of each module in system is described, the system is deployed in the Gn interface of GPRS network and have collected a large amount of data of mobile users. Through statistical analysis of this data, several laws of mobile user’s session distribution and the module of session durations are found. In addition, the quality of network was also discussed by presenting many detailed pictures. Finally, a summary and outlook on the monitoring in GPRS network is presented.
