Compared with the previous generation communication technology, the network transmission speed faster, the downward rate can reach 100 Mbps and 150 Mbps, 20 ~ 30 times faster than 3 g, upload speed can reach 20 Mbps ~ 40 Mbps.This rate can meet the requirements of almost all users for wireless service.But in bring convenience to mankind at the same time, also poses a more serious security threats.As mobile terminal (ME) of the enrichment of computing and storage resources, mobile operating system was born, and a variety of wireless applications, make ME is facing more and more security threats, the safety of the next generation mobile communication system (4G) research is imminent.4G system in determining the network structure of the security issues should be as an important factor that has gone hand in hand with other core technology study, and finally it as a key part in
