摘要: 中继作为LTE-A的关键技术之一,既能优化网络覆盖,还可以提高系统容量。然而中继的引入也为系统带来了诸多安全挑战。分析了中继部署场景下用户终端切换时的安全问题,给出不同切换场景模式的安全解决方案,以保证切换后通信的正常进行,并且通过建立Petri网络模型对所设计流程进行了分析。最后,对移动中继切换时的安全处理进行了讨论。

Abstract: As one of the key technologies in LTE-A, relay can both optimize coverage of the network and increase the system capacity. However, the introducing of relay also brings many security challenges to the system. The security issues in relay related handover processes were mainly analyzed, and then the corresponding solutions were proposed for security handling. With those solutions, mobile users in the network can communicate effectively after the handover process. The designed process was also analyzed by using Petri network model. Finally, the handover security of mobile relay was discussed.
