Abstract:

Low-Altitude Intelligent Network (LAIN), as a new type of intelligent network, relies on space-air-ground-sea facilities to constitute a digital intelligent network system. It is a key component of the space-air-ground integrated network, and can support the seamless and ubiquitous connections of the sixth generation communication technology and promote the development of intelligent network service from ground to low-altitude space. However, LAIN is still in the developing stage and faces the following key challenges: intractability of aerial control, severe spectrum interference, and multi-dimensional resource limitation. This article focuses on the issues of LAIN architecture and safety control, including the current development status of low-altitude network and its significance for industrial technology transformation. Then, from the perspective of spectrum resources, network resources, and airspace resource management, the recent related works are analyzed. Furthermore, we analyze the key technologies such as low-altitude aircraft air-ground spectrum sharing, sensing, transmission, computing networking coverage, low-altitude airspace intelligent supervision, and point out future development directions. Finally, an application demonstration of LAIN is proposed, aiming to satisfy the significant requirements for efficient operation and safety in low-altitude airspace, and providing the theoretical basis as well as technology for the further development of the next generation space-air-ground integrated network.

Key words: low-altitude intelligent network, space-air-ground integrated network, low-altitude aircraft, resource management, low-altitude airspace
