Abstract
GGSN is the gateway GPRS support node. Internetworking between external data packets and GPRS networks is the main function of the GGSN. To an outsider GGSN acts like a subnetwork as it conceals GPRS software. The GGSN, when it receives data for a specified user, it first checks if the user is an active user and if the user is active then it forwards data to the SGSN, otherwise it is discarded. The GGSN stores various fields of customer data such as MSNID, the NAT port block, allocation and deallocation time and so on. All telecom companies use the process of natting. Natting is a concept in which each public IP is shared by 1500 private IPs. It is also mandatory for telecom companies in India to follow TRAI regulations for storing of telecom data. TRAI requires data of the past 7 years to be stored. Cyber cells tracking cybercrimes, when investigating a case can only trace back to the public IP of the telecom company and without permission from the telecom company they have no access to the files. Even after gaining access, to go through several million logs to find the correct log is a time-consuming and exhausting process. This paper presents an application which allows fast searching through GGSN logs to produce efficient results in a much shorter period of time. Work which would otherwise take several hours can be accomplished in minutes. The application helps enforce security by making the process of tracking these malicious end users, through a large amount of data, easy and fast.
