摘　　要：对当下PTN(分组传送)网络大规模承载的TD-LTE(长期演进技术)业务场景进行分析研究,针对不同层面提出一种基于PTN的TD-LTE网络的具体保护部署方案。着重讨论核心层以及相应的故障点保护倒换方式,并进行现网测试,给出部分技术参数的统计对比。研究表明:优化网络保护方案后,在故障发生时业务能够保证不被中断。This paper makes an analysis and study of the TD-LTE business scenarios carried by PTN network in large scale,and proposes specific protection deployment plans for different levels.The core layer and the corresponding fault point protection switching mode are discussed emphatically as well.The present network is tested,and the statistical comparison of some technical parameters is given in view of the scheme proposed in this paper.The study shows that the optimized network protection scheme can ensure that the service is not interrupted when the fault occurs.
