Abstract
In order to meet the long-term requirements of global comprehensive three-dimensional coverage and access anytime, anywhere in the future, the space-air-ground integrated network (SAGIN) as an ideal network architecture has become an important research direction in recent years. The paper describes some typical business scenarios in future communications, analyzes the network architecture and composition of SAGIN, and studies the key technologies to realize SAGIN. Finally, it points out some of the research directions of SAGIN, such as IoT services.
