Abstract: In response to the challenges faced by dynamic networking, multi-mode heterogeneity, and network operation and maintenance of the future integrated satellite and mobile network, an integrated architecture of digital twins is proposed. This architecture includes a data native layer, a digital twin layer, etc., which can greatly simplify network planning and construction, and make operation and maintenance intelligent. With regard to the new architecture, key technologies and applications such as data native, knowledge map, network simulation, and network strategy optimization in the integrated satellite and mobile network.
