Abstract

Abstract:

The research mainly starts from the development trend of 5G+ satellite integration, and conducts research and analysis on typical domestic and foreign satellite Internet of things/internet solutions, and then leads to application scenarios and services requirement for the development of 5G+ satellite integration, including research and discussion on the technical requirements of 5G satellite space-ground integrated dual-mode terminals, finally, the challenges faced by 5G satellite dual-mode communication terminals are given.With a view to providing industry with guidance on the challenging aspects of standardization and pre-development of 5G+ satellite dual-mode terminals, and to provide useful suggestions and references for overcoming these challenges.

Key words: 5G, satellite IoT/Internet, dual-mode terminal, integration communication scenario of satellite and UTRAN
