面向智能化切片的服务化等级保障技术增强和研究

网络切片是5G垂直行业应用的重要使能技术,可以为不同应用场景提供差异化服务,切片服务等级保障使得运营商能够准确感知和评估各类业务的服务质量,以便进行服务质量的保障,然而,在切片的应用中,由于缺乏关于业务体验的实时监控,使运营商无法有效评估各类业务的服务质量。为了让运营商可以有效地评估各类业务的服务质量,首先利用网络数据分析功能分析得到切片中某个业务的用户体验,然后借助人工智能技术,基于业务体验数据建立业务模型,评估整个切片在运行态的切片SLA,从而更新切片的资源配置和调度,实现SLA的增强。

Enhancement and Research of Service Level Assurance Technology for Intelligent Slicing

5G network slicing is an important enabling technology for 5G vertical industry applications,which can provide differentiated services for different application scenarios.The slicing service level assurance(SLA)enables operators to accurately perceive and evaluate the quality of various services in order to assure the service quality.However,in slicing applications,due to the lack of real-time monitoring of service experience in slicing,operators cannot effectively evaluate the service quality of various services.To help the operators evaluate the service quality of various services effectively the network data analysis function(NWDAF)is adopted to analyze the user's service experience of a certain service in the slice,and then a service model is established based on the service experience data through artificial intelligence technology.Finally,the slicing SLA is evaluated at the running state of the whole slice,thereby updating the resource allocation and scheduling of the slice and enhancing the SLA.
