Advanced Low Earth Orbit Satellite Network Protocol and Security Technologies )(2/3)

Project Details

Description

Due to seamless connection and high-speed transmission capabilities of Satellite Communication (SatCom), 3GPP recommends that 5G terrestrial systems and satellite systems cooperate to ensure the continuity of 5G network services. Recently, international satellite companies are scrambling to launch low-orbit satellites (LEO) to provide network coverage services. However, satellite-terrestrial networks face tough challenges, including designing handover scheme of high-mobility LEO cells, channel state (CSI) reporting under long-communication-delay LEO networks, and reducing interference between satellite networks and terrestrial networks. This project proposed a three-year plan for the above-mentioned important issues. In the first year, we mainly deal with the handover mechanism and the channel state (CSI) prediction. In the second year, we aim to reduce interference between terrestrial networks and LEO networks. In the third year, we consider satellite network security mechanisms. As the satellite network is considered as a solution to the software and firmware update of the Internet of Things, we also implement the network transport layer communication security mechanism and software update mechanism in the ARM chip.
