摘要
随着社会的发展与进步,我国已逐渐进入信息化时代。信息是社会、人文发展的必备品,人们对移动通信网络的需求也与日俱增。如今,正在运营的2G、3G网络已经无法满足消费者目前的日常需求。为了跟上时代的步伐,满足当代消费者的需求,4G网络应运而生。第四代移动网络(4G)系统致力于无缝融合不同无线通信技术并支撑高速率通信环境。伴随社会多媒体业务和通讯数据业务的发展,4G网络已广泛应用于移动计算机、移动通讯设备、移动数据等各个方面。但是,由于4G网诞生时间短,技术层面尚未完善,并且开放性、无线传播等特点使得4G网络安全问题也一直困扰着整个网络环境和移动通信系统。文中介绍了4G网络概念、关键技术、网络结构,分析了4G网络面临的安全威胁,并提出了防范措施和对策。
With the development and advance of the society,China has entered the information age gradually. The progress of the society and the humanity is based on information. The demand for mobile phones will gradually increase. At present,the technology of 2G、3G network is very difficult to satisfy people＇s needs. In order to keep up with the pace of the times and meet the needs of the customers,4G network is produced. The fourth-generation mobile network（ 4G） system is committed to the seamless integration of different wireless communication technologies and supports high speed communication environments. With the development of multimedia communication and data service,4G network is widely used in mobile computer,mobile communication equipment,and mobile data and so on. However,because the 4G network was born a short time,the technical level not yet perfect,and the openness,wireless communication and other features of the 4G network make the security issues have been plaguing the entire network environment and mobile communication systems.In this paper,the concept,the key technology and network structure of 4G network is introduced,and the security threat faced by 4G network is analyzed,and the preventive measures and countermeasures is put forward.
