Mobility management of integrated sensing and communication technology for distributed cooperative network

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.
