【Abstract】 This paper thoroughly explores the specific architecture of digital twin technology in integrated space-air-ground communication, along with its applications in network optimization. The digital twin is divided into a virtual integrated space-air-ground network and an intelligent decision-making layer. The virtual network serves as an accurate mapping of the physical space-air-ground communication network, supporting real-time monitoring and test verification functions. In the intelligent decision-making layer, network optimization is achieved through environmental awareness and business forecasting. Finally, the paper validates the immense potential of digital twin technology oriented towards integrated space-air-ground networks in dynamic communication network optimization, providing innovative insights for the future development of network optimization.更多还原
