基于模糊理论的5G异构网络切换算法研究

Research on Handover Algorithm of 5G Heterogeneous Network Based on Fuzzy Theory

随着4K视频、AR、VR移动业务的快速发展,4G宏站已无法满足大众对网速的需求,需要新建大量5G小基站(如微微基站、毫微微基站、毫米波基站)混搭于4G宏站网络中。但小基站覆盖范围小,会导致手机频繁切换,因此设计一种基于模糊逻辑的高效5G异构网络切换算法非常重要,以此来降低UE的掉线率及减少其在5G异构网络中的切换次数。通过仿真对比发现:文章中提出的切换算法与现有切换算法相比在掉线率和切换次数上有良好表现。

With the rapid development of 4K video,AR and VR mobile services,4G macro stations can no longer meet the demand for network speed.Therefore,many 5G small base stations will be built,such as PicoCell,FemtoCell and millimeter wave base stations.However,the small coverage of small cells will lead to frequent handovers of mobile phones.Therefore,it is very important to design an efficient handover algorithm for 5G heterogeneous networks based on fuzzy logic,so as to reduce the dropping rate of UE and the handover times in 5G heterogeneous networks.Through simulation comparison,it is found that the handover algorithm proposed in this paper has good performance in dropping rate and handover times compared with existing handover algorithms.
