摘 要:地铁场景从 4G 时代以来一直就是流量承载力强的典型场景,且存量线路体量大、协调难、系统复杂。为了在存量场景中快速实现地铁 5G 覆盖,同时保证用户感知和业务体验,文章重点研究了不同话务线路的 5G 覆盖应用方案,并提出一套站轨间的优化策略,已在南京全线路推广。相较于传统方案,该方案在工程施工、网络能力、切换性能等方面均有明显提升,可为后续地铁 5G 优化提供参考借鉴。

Abstract: The subway scene has always been a typical scene with strong traffic carrying capacity since the 4G era, and the existing lines are large, difficult to coordinate, and the system is complex. In order to quickly realize the 5G coverage of the subway in the existing subway scene, while ensuring user perception and business experience, this paper focuses on the research of 5G coverage application schemes for different traffic lines, and proposes a set of optimization strategies between stations and tracks, which have been promoted throughout Nanjing. Compared with the traditional scheme, this scheme has significantly improved in engineering construction, network capacity, switching performance and other aspects, which can provide reference for the subsequent 5G optimization of subway.
Keywords: existing subway scene; 5G coverage; station track optimization; user perception
