4G无线通信系统的网络安全分析

随着计算机技术无线通信技术的不断融合，移动通信系统经历了1G（第一代）、2G（第二代）、3G（第三代）发展历程。2013年12月4日工信部正式向三大运营商发布4G牌照，我国正式商用下一代通用无线通信系统（4G）。而4G系统是全IP网络并支持高速通信环境，其安全问题比以往的无线通信系统更加复杂，是业界与学界研究的热点。本文重点分析力4G系统所面临的安全威胁，并针对安全威胁提出了4G系统安全机制的制定策略。

4G network security analysis of wireless communication system

with the continuous fusion of computer technology of wireless communication technology, mobile communication system has experienced （ first generation ） 1G, 2G （ second generation ） , 3G （ third generation ） development. In December 2013, 4 day labourer ministry official 4G licences to the three carriers, China formally commercial the next generation of universal wireless communication system （ 4G ） . And 4 g system is all IP network and support high--speed communication environment, the security problem of wireless communication system is more complicated than in the past, is a hotspot of research on the industry and academia. The essay focuses on the analysis of force of 4 G system facing security threats, and puts forward 4G system against security threats the strategy of security mechanisms.
