21世纪是信息科技时代,近年来的不断发展进步,我国可以说全面进入信息化模式。信息是人类社会、文明发展的产物,是科技的成果,而人们对移动通信科技的需求。之前,全面普及的2G/3G网络已经不能达到人们的日常工作和生活要求。所以,顺应时代的潮流,也为了达到当今社会人们的要求,4G网络为此而生。然而,因为4G网络发展时间较短,技术层面不是很完善,而且无线传播、开放性等状况,导致4G网络的安全保障问题是现今网络环境与移动通信技术中一大难题。本篇文章主要论述了4G网络定义、主要技术、网络架构,并阐述了4G网络面对的安全难题,然后介绍了相关的防范措施。
The 21st century is the era of information technology. In recent years, our country has been continuously developing and progressing. China can fully enter the mode of informationization. Information is the product of the development of human society and civilization, the result of science and technology, and the demand of people for the science and technology of mobile communication. Before the full penetration of 2G / 3G network has been unable to meet people’s daily work and life requirements. Therefore, conform to the trend of the times, but also to meet the requirements of today’s society, 4G network was born. However, because of the short development time of 4G network, the imperfect technical level, and the status of wireless transmission and openness, the security of 4G network is a major challenge in the current network environment and mobile communication technologies. This article mainly discusses 4G network definition, main technology, network architecture, and expounds the 4G network security challenges, and then introduces the relevant preventive measures.
