5G高密重载场景ToB/ToC组网策略研究

Research on ToB/ToC Networking Strategy in 5G High-density and Heavy-load Scenario

为满足冬奥高密重载组网需求,利用国家体育场环境实施空频多维度5G立体组网、精细容量规划、精准区域覆盖,并在全场景应用分布式大规模天线技术、端到端5G切片技术、载波聚合、超级上行等多种5G新技术,提升极致性能。同时,针对不同业务类型实施ToB/ToC网络分层、ToB业务全场景隔离等手段保证高密重载场景下各业务感知,既能够承载全场数万人5G网络压力,又为UHD超高清直播等创新业务多样化需求预留充足的能力。

In order to meet the demand for high-density and heavy-load capacity in Winter Olympic venues,multi-dimensional 5G networking technology,detailed capacity planning and accurate area coverage is implemented with the national stadium environment,and distributed massive MIMO antenna technology,end-to-end 5G slicing technology,carrier aggregation technology,uplink switching technology and other 5G new technologies are applied to improve network performance.At the same time,ToB/ToC network layering,ToB service full-scene isolation and other means are implemented for different service types to ensure the service awareness under high-density and heavy-load scenarios,which can not only bear the 5G network pressure of tens of thousands of people in the field,but also reserve sufficient capacity for the diversified needs of innovative businesses such as UHD ultra-HD live broadcast.
