摘要
随着5G网络的不断演进,面向行业用户的解决方案也更加灵活,数据分流可以很好地满足客户对于数据不出园区、本地卸载、低时延等迫切需求。介绍了5G网络中数据分流能力的需求背景和分流技术原理,同时结合运营商现网实际部署情况,论述了基于多数据网络名称(data network name,DNN)分流和基于上行链路分类器(uplink classifier,UL CL)分流两大类数据分流方案的应用场景、技术实现,并对不同方案的优点和局限性进行了对比分析,最后通过实际案例验证了方案的可行性。
With the continuous evolution of 5G network, 5GtoB solution for industrial users is also more flexible.Data offloading can well meet the urgent needs of customers for data not leaving the park, local unloading, local support, low delay and so on. The demand background of data offloading capability in 5G network and the relevant principles of diversion technology were introduced. At the same time, combined with the actual deployment of operators’ existing network, the application scenarios and technical implementation of two kinds of data offloading schemes based on multi data network name(DNN) and uplink classifier(UL CL) were expounded, and the advantages and limitations of different schemes were compared and analyzed. Finally, the feasibility of the scheme was verified by an actual case.
