摘　　要：分析通感一体化技术的工业界研究以及应用情况,基站自发自收感知模式是当前5G-Advanced(5G-A)阶段通感网络部署的普遍选择。基于基站自发自收感知模式,确定数据级融合的感知协作层级,根据感知特征测量精度定义感知置信度,并作为感知数据融合的合并权值,同时提出一种感知功能分布式部署的网络架构。设计非合作终端的分布式协作移动性管理方案,其锚点基站的建立、协作基站的选择和锚点基站的切换均由通感基站控制执行。设计合作终端的分布式协作移动性管理方案,其锚点基站的建立和协作基站的选择由通感中心控制执行,而锚点基站的切换由通感基站控制实现。Analyzing the research and application of integrated sensing and communication(ISAC)technology in the industry,the self-transimit-self-receive sensing mode of base stations is a preferred choice for the deployment of ISAC networks in the current 5G-Advanced(5G-A)stage.Based on the self-transimit-self-receive sensing mode,the measurement accuracy of sensing features was utilized to define the sensing confidence metric,which was used as the combined weight for cooperative sensing data fusion.Then,a network architecture was provided with the distributed deployment of sensing functions.In accordance with the service characteristics of sensing for illegal targets and valid terminals respectively,the corresponding mobility management solutions were designed for distributed networks.For illegal targets,the establishment of anchor stations,selection of cooperative stations,and handover of anchor stations were all controlled and performed by the ISAC base stations.For valid terminals,the establishment of anchor stations and selection of cooperative stations were controlled and performed by the ISAC center,while the handover of anchor stations was controlled and implemented by the ISAC base stations.
