| 摘 要： | 鉴于电信运营商对运营成本的关注，LTE（长期演进，Long Term Evolution）重点考虑建立集中统一的网管系统，此外还要支持远程操作。诸多新功能对LTE网管系统提出了新的安全需求。本文详细阐述了LTE网管系统的体系结构、数据交互需求及其面临的安全威胁，结合其体系结构将网管系统划分为计算域、用户域、公共安全服务域、外部接口域等安全域，并根据各域的安全需求分别归类到高、中、低三个安全等级，最后分析了安全域划分的优点。LTE网管系统安全威胁分析与安全域划分有助于网管系统的安全防护策略设计。

| Abstract: | In view of telecom operators focusing on operating expenditure,longterm evolution (LTE) aims to establish centralized network management system.In addition,network management system has to support remote access.Such new functions inevitably cause new security requirements for LTE network management system.Several key issues on LTE network management,such as architecture and security threats,are discussed in this paper.The security domains of LTE network management are divided into computation domain,user do... |
