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.
