摘要
相比全球移动通讯系统(Global system for mobile communications,GSM)网络,长期演进(Long term evolution,LTE)中增加了双向鉴权机制,伪基站的防治得到了改善,但受传统硬件设施的桎梏,检测和跟踪代价昂贵、灵活性也有所不足。不仅如此,随着通信技术的升级,伪基站更加偏向于智能化和小型化,难以被侦测。针对以上问题,本文基于软件无线电技术,对相关伪基站识别算法进行改进,提出了一种新的LTE伪基站识别方案。通过搭建软件无线电平台和建立LTE下行广播信息接收链路获取基站的关键小区相关信息,并基于信息一致识别算法对基站进行判别。该方案选择了两个测试场景,正确地检测到了合法基站,也检测到了伪基站的信息,验证了本文识别方法的可行性。结合软件无线电自身的优点,本文形成的技术具有系统升级效率高、成本低的优势。
Compared with the GSM network,the two-way authentication mechanism has been added to LTE,and the prevention and control of pseudo base stations are improved.However,due to the shackles of traditional hardware facilities,detection and tracking are expensive and the flexibility is insufficient.Not only that,with the upgrade of communication technology,pseudo base stations are more inclined to be intelligent and miniaturized,which is difficult to detect.In response to the above problems,based on the software radio technology,this paper improves the related pseudo base station identification algorithm and proposes a new LTE pseudo base station identification scheme:Acquiring a key cell of the base station by building a software radio platform and establishing an LTE downlink broadcast information receiving link Relevant information,and the base stationis is distinguished based on the consistent information recognition algorithm.The scheme selected two test scenarios,correctly detected the legal base station,and also detected the information of the pseudo base station,which verified the feasibility of the identification method in this paper.Combined with the advantages of software radio itself,the technology formed in this paper has the advantages of high system upgrade efficiency and cost reduction.
