With the popularization of 3G mobile network, solutions to possible security problems is becoming more and more important.This paper, based on GTP protocol, designed a state machine for GTP tunnel information management to make a trace analysis, and illustrated how firewall monitors GTP package status,all in an effort to bring a new perspective and an approach to the research on GTP attack defense.
