摘　　要：通感一体化(Integrated Sensing and Communication,ISAC)是6G研究的重点方向之一,目前业界主要关注点聚焦在基站及终端感知能力的实现,对于6G核心网架构如何增强以支持通感功能、感知能力在6G核心网的网络功能分布、感知结果如何对第三方开放等端到端流程尚处在前期研究阶段。提出了一种通感一体化功能在6G网络架构中的关键技术实现方案,包括:通感功能在6G核心网中的分布;增强5G服务化架构(Service Based Architecture,SBA)架构,新增双总线方案,利用数据通道接口(Data Channel Interface,DCI)总线传输感知原始数据;利用服务化接口(Service Based Interface,SBI)传输感知测量量或感知结果;端到端感知和开放流程的实现方法。Integrated sensing and communication(ISAC)is one of the key research directions of the 6G network.At present,the industry focuses on the implementation of the sensing of base stations and terminals.How to enhance the architecture of the 6G core network to support the sensing function,how to distribute the sensing function in the 6G core network,and how to open and release the sensing result to third parties are still in the early research stage.This paper proposes a key technical implementation solution of the ISAC in the 6G core network,including the distribution of the sensing functions in the 6G core network.The 5G service based architecture(SBA)is enhanced,and a dual-bus solution is added.The original sensing data is transmitted by using a data channel interface(DCI).Sensing measurement data or sensing results are transmitted through the service-based interface(SBI).And the implementation methods of the end-to-end sensing flow and exposure are proposed.
