Conclusion

In this paper, we introduce a mobility-aware algorithm to identify communicating satellites for Starlink UTs in motion. Beyond the regular schedule-driven 15-second handover intervals, we revealed that Starlink UTs can perform multiple beam switching attempts to connect to different satellites, circumventing transient obstructions or degraded LoS conditions. We demonstrated the network impact of beam switching events, especially prolonged connection outages and the occurrence of latency spikes in addition to regular handover events. By identifying the communicating satellites for Starlink UTs in motion, this paper paves the way for further research into understanding the end-to-end performance of Starlink networks and its satellite selection strategies. Future research on developing LEO constellation simulations can incorporate both the communicating satellite identification results and network performance traces for realistic and mobility-aware scenarios.

原因:

1. UT 的移动性 (朝向频繁变化)
2. 环境遮挡

导致:

1. 多次动态波束切换
2. 链路质量发生退化

本文创新点:

1. "动态波束切换"程度如何? 影响如何?
2. "移动感知卫星识别方法": 根据 UT 诊断数据 + 连接卫星信息, 解释网络性能, 识别动态波束切换事件

笔者锐评

毫无创新性, 只是把已有的内容重新组织了一下, 最多有点"辛苦费"...

建议本文看看结论就行, 过程量实在没啥看点
