LTE规模部署中潜在的网络安全风险分析

近年来，LTE成为全球通信行业的发展热点。针对LTE/SAE的安全特性，对LTE规模部署过程中面临的如控制平面拥塞、异常流量攻击、网络融合等各层面的安全风险进行深入分析，并提出相应的安全防护建议。这些安全防护建议包括安全域划分、信令保护、异常流量防护等措施，以期对我国LTE规模部署的安全保障提供必要的参考。

Analysis on Potential Network Security Risk of LTE Scalable Deployment

In recent years, the deployment of LTE network has become a hot spot. Based on the introduction of the security design of LTE/SAE, a deep analysis of security risk was made including control plane's congestion, abnormal traffic attack, network convergence which might be brought during the LTE deployment. After that, some solutions were proposed like division of security domain, signaling protection and abnormal traffic protection to provide a security reference for the LTE deployment in China.
