Abstract：With increasing demand for access and expansion of network scale, it is necessary to integrate communication, sensing, and computing technologies in 6G networks to enhance the overall system performance and utilize digital twin technology to improve real-time maintenance and modeling capabilities.The limitations of 5G were analyzed, and the application of integrated communication, sensing, and computing technologies in space-air-ground integrated networks and the role of digital twin technology in building a future “digital twin and smart pervasive” world was studied.A digital twin network implementation scheme based on the integration of communication, sensing, and computingtechnology was proposed, mapping the integrated air-space-ground network into the digital world to enable feedback influence on the physical world.The requirements and advantages of 6G in terms of deep integration of communication, sensing and computing and global coverage were also explored, aiming to achieve the vision of “one thought encompassing the universe, everything responding as desired”.
