5G切片技术在5G toB业务中的应用研究

Research on the Application of 5G Network Slicing Technology in the Field of 5G Enterprise Business

3GPP关于5G QoS等系列标准和规范已陆续推出[1],基于5G切片技术在toB业务中的行业应用需求旺盛,文章从运营商角度,探索、设计了贯通终端、无线、承载、核心及固网的端到端的5G切片专线的业务方案和服务标准,依托于中国电信5G、IP RAN、OTN等网络,开发了基于5G接入,提供点对点专线、入云专线等功能的综合型产品,在带宽、QoS、拓扑、连接数量、连接区域等方面提供可定制的差异化服务。并组织在北京等多省联合友好客户进行了业务验证,对技术方案、业务设计、网络和IT部署方案进行测试,系统功能、性能均达到业务设计指标。

In response to the strong demand for industry applications of 5G slicing technology in the toB business,3GPP standards and regulations of the 5G QoS have been laid out progressively.From the perspective of service carriers,this article elaborates the design of the business scheme and service standard for the end-to-end 5G network slicing dedicated line,which connects terminal,wireless,bearer,core and fixed network.Relying on China Telecom 5G,IP ran,OTN and other networks,we have developed comprehensive 5G-access-based products to provide point-to-point dedicated lines,cloud access dedicated lines,and other functions.The business scheme described herein has been verified in Beijing and other provinces via collaboration with potential customers.Specifically,the technical solution,business model,network and IT deployment scheme are all successfully tested.The results indicate that the proposed business scheme provides adequate system functions and its performance meets the industry work design criterion.
