Abstract: The integration of terrestrial network and satellite network is an inevitable trend in technological evolution. 5G NTN has achieved the integration of satellite network and terrestrial network at standard level. In the evolution towards 6G technology, satellite and cellular communication will move towards deeper integration, comprised of standard, device, resource, and service, etc. Starting from technical requirements and application scenarios, this article proposes a kind of network architecture for the integration of terrestrial network and satellite network, analyzes relevant key technologies, and looks forward to future technological trends. The outcome of this study serves as a reference for future research in the integration of satellite and terrestrial network for 6G.

Keywords:  Integration of terrestrial network and satellite network; 6G; network architecture; cooperative transmission.
