Mobile communication technology from 1G To 4G、 Until then 6G Development process of , It reflects people's communication needs from meeting people to people to people and things 、 And then to the development of intelligent association of all things . Now , Update iteration of ground communication network 、 Accelerating the deployment of satellite communication network and exploring the construction of marine communication network , It has laid the foundation for the arrival of the air, earth and sea integrated network . The air, earth and sea integrated network will be organically integrated by various heterogeneous networks , So as to realize the vision of seamless global coverage .

As early as 2000 year , The United States took the lead in putting forward the idea of building a heaven earth integrated information network , Integrate the respective advantages of satellite network and ground network , Realize on-demand customization under the unified framework , So as to provide users with better services [1]. China lists the integrated network of heaven and earth as scientific and technological innovation 2030 One of the major engineering projects , And incorporated into the country “ Much starker choices-and graver consequences-in ” Planning outline and 《“ Much starker choices-and graver consequences-in ” National Science and technology innovation plan 》[2]. The integrated network of heaven and earth is strategically 、 Fundamental and a series of irreplaceable significance , Become a major infrastructure related to national security and national economy , It provides a solution for achieving seamless global coverage , But the equipment is expensive . With the aerial platform （ Such as airship 、 Hot air balloon 、 UAV, etc. ） The fall in cost , On the basis of the space-based integrated network, the idea of integrating the space-based network into the space-based network is put forward [2].
