中文摘要: 针对传统的移动性管理基站在5G超密集网络部署的特定场景中所面临的信令开销大、数据传输效率低等问题，本文研究基于SDN架构的5G通信网络中的垂直切换算法，充分利用SDN控制器中的全局化的网络状态信息，计算最优的切换决策结果，尽可能的减少移动节点收集网络状态信息所带来的时延以及网络开销.利用Matlab对提出的切换管理策略进行了仿真，相对于LTE系统的切换管理机制，在切换时延以及平均切换次数上都有优势.
Abstract:As the high signaling cost and low data transmission efficiency of traditional mobile management strategy in 5G ultra-dense network deployment, this study proposed a handover algorithms in 5G based on SDN architecture. By the use of the global network state information in SDN controller to make the optimal handover decision, the delay and network resource cost caused by mobile node collecting network status information can be reduced. The proposed handover management strategy is simulated by Matlab. Compared with the handover management mechanism of LTE system, it has advantages in handover delay and average handover times.
