高铁无线网络协同组网策略研究

The research on networking strategy for special network of high-speed train

本文针对高铁5G公专网的频率干扰问题,结合高铁专网资源占用时间短和瞬时容量要求高的特点,对高铁5G公专网的组网策略开展了研究分析,提出了不同公专网场景下,同频加协同以及公专网共网覆盖的组网方案,有效提升了网络质量和用户感知,为5G高铁专网部署及协同优化提供重要指导。

In this paper,the frequency interference problem of the 5G special network of the high-speed train was studied and analyzed.Considering the short-time resource occupation of the 5G special network,the network formation strategy of the 5G special network was also analyzed.The different networking strategies network under different scenes were put forward,including inra-frequency networking and co-covered strategy,which effectively improved the network quality and user perception,and provided important guidance for the deployment and coordination of the network.
