TD-LTE 4G宽带移动通信环境下两种安全防护方式比较

Comparison of Two Types of Encryption Method Used in TD-LTE

随着4G TD-LTE技术的快速发展,移动通信系统逐渐步入4G时代。由于4G网络带宽的提高,4G宽带移动网络的可用性大大提升,但同时安全性也大大降低,如何保障宽带移动通信系统的信息安全,是亟需解决的关键问题。通过在宽带移动通信系统中增加安全防护设备的方式可以有效解决宽带移动通信系统的信息安全问题。针对“门卫方式”和“调用方式”两大类安全防护方式进行了论述和比较分析,并给出了宽带移动通信环境下如何选择安全防护技术的建议。

With the rapid development of TD-LTE technology,mobile communication system network gradually enters into the 4G era.Due to the increased bandwidth of 4G network,the availability of 4G broadband mobile network is greatly increased,but at the same time,its security is greatly reduced,and how to ensure the information security of broadband mobile communication system now becomes a key issue that needs to be promptly solved.The information security problem of the broadband mobile communication system can be effectively solved by adding security protection devices to the broadband mobile communication system.In-depth discussion and comparison is done on the two types of security protection method—guard-type and call-type. Finally, suggestion of how to select the method is given.
