摘要
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。
Twenty-first Century is the era of information technology, in recent years, the continuous development and progress, our country can be said to enter the information model. Information is the product of the development of human society and civilization, and it is the result of science and technology. Prior to the full popularization of the 2G/3G network has been unable to meet people＇s daily work and life requirements. Therefore, in line with the trend of the times, but also in order to meet the needs of today＇s society ,4G network for this. However, because of the development of 4G network time is short, the technical level is not very perfect, and wireless communication, openness,lead to security problems of 4G networks is a big problem in today＇s network environment and mobile communication technology. This article mainly discusses the definition of the 4G network, the main technology, network architecture, and describes the security problems faced by the 4G network, and then introduces the relevant preventive measures.
