Abstract: Satellite communication network system will become an important part of the global network in the future. Modern satellite manufacturing technology, launch technology, and network technology have made mega low earth orbit (LEO) constellation communication networks a reality. The research and development of mega LEO constellation satellite communication networks in the future, including satellite services and applications, the evolution and technical challenges of satellite communications, user requirements for quality of service (QoS), 5G standard use cases, and 5G deployment scenarios, are discussed. Finally, the role of mega LEO constellation satellite communication networks in the future development of 6G is highlighted.
