5G承载网回传带宽估算模型的优化与应用

Optimization and application of 5G bearer network backhaul bandwidth estimation model

在5G建设初期,业务需求不明确,技术成熟度有待完善,流量增长方式难以预测,如何根据建设场景的不同对现网承载系统能力进行评估以及合理地选择5G承载网建设方案是现阶段炙手可热的难题。通过对典型配置的5G单基站承载带宽需求评估方法的理论研究,结合4G网络建设的工程经验,以全国抽样调研数据论证理论带宽估算模型与实际流量水平的巨大差距,以此为借鉴,为科学地指引5G承载网初期的规划、建设,提出一种5G承载网回传带宽估算的优化模型,通过分场景举例说明其在新建、扩容、升级3种5G承载网演进路径中均有其应用价值。

In the early stage of 5G construction,business requirements are unclear,technology maturity needs to be improved,and traffic growth methods are unpredictable.How to evaluate the capacity of the existing network bearer system according to different construction scenarios and choose a reasonable 5G bearer network construction plan problem.Through theoretical research on the typical configuration of the 5G single base station bearer bandwidth demand assessment method,combined with the engineering experience of 4G network construction,the national sampling survey data was used to demonstrate the huge gap between the theoretical bandwidth estimation model and the actual traffic level.The initial planning and construction of the 5G bearer network was scientifically guided,and an optimized model for the estimation of the 5G bearer network backhaul bandwidth was proposed,and its application in the evolution path of the new 5G bearer network through new scenarios,expansion,and upgrade value was illustrated.
