摘要:

地铁作为城市动脉和大众化的交通工具,是最具可持续性的交通运输方式,随着地铁等轨道交通运营里程的增长、客运量的提升,其在运营、维护、安防、调度等方面均面临更大的挑战,亟须信息化手段来提升地铁运营服务水平,而地铁信息化的基础则是有效的室内网络覆盖。目前涉及室外广域、室内密闭静止场景、室内密闭高速运动场景等多场景覆盖要求,针对不同覆盖场景,如选择相同网络方式覆盖,可能存在成本较高、覆盖效果不佳的问题。因此,针对地铁网络覆盖,需要灵活组合宏基站、微基站、室分、泄漏电缆等方式,结合切片、资源块(RB, resource block)保障、自动越区切换、自动登录等保障技术,在成本最优的条件下,满足网络的无感切换、高数据速率、低时延、高容量和大规模连接等指标要求,确保地铁场景下toB及toC业务正常运行。探讨了地铁场景下5G网络立体覆盖方案,为其他地铁专网覆盖提供了重要的参考依据。

Abstract:

As an urban artery and popular means of transportation, the subway is the most sustainable way of transportation.With the increase in operating mileage and passenger volume of subway and other rail transit, it faces greater challenges in operation, maintenance, security, scheduling, and other aspects.There is an urgent need for information technology to improve the level of subway operation services.While the foundation of subway informatization is effective indoor network coverage.At present, there are coverage requirements of multiple scenario such as outdoor wide area, indoor enclosed static scenes, and indoor enclosed high-speed sports scenes.For different coverage scenarios, if the same network method is chosen for coverage, there may be problems of high cost and poor coverage effect.Therefore, for the coverage of the subway network, it is necessary to flexibly combine macro station, micro station, room separation, leakage cable and other methods, combined with resource block (RB) guarantee, automatic handover, automatic login and other guarantee technologies, to meet the requirements of the network’s indicators such as insensitive switching, high data rate, low latency, high capacity, and large-scale connection under the optimal cost conditions, to ensure the normal operation of toB and toC business in subway scenarios.The 5G network stereo coverage scheme was studied in subway scenario, providing important reference for the coverage of other subway specialized networks.

Key words: subway, 5G network, multiple coverage scenarios, wireless network coverage, senseless switching
