| Abstract: | The satellite-ground fusion networks can not only meet the demands of emerging services such as auto-driving and large connections, but also be widely used in the disaster alarming and public safety applications. To serve ground applications with high efficiency and low delay for satellite ground fusion network, the key technologies of satellite-ground fusion intelligent networking are proposed. The technologies including networking architecture, data perception, access control, multi-dimensional network slicing, and time-sensitive routing and forwarding are then expounded in terms of principle and performance. Finally, the existing challenges and future directions are discussed. |
