The standard of satellite mobile communication released by 3GPP is still in the 3G stage. Research on satellite LTE series standards, such as communication protocols and flows
It often uses network simulation. The LTE simulation model LENA in the EPS system and the open source network simulation tool NS 3 is briefly introduced. The difference between the LENA model and the real LTE system is emphatically discussed. In view of the characteristics of the satellite mobile communication environment, such as large delay, high error code, and the fading of the channel are different from the ground, the LENA model is analyzed and summarized for the on-board LT. E system simulation needs improvement, which lays the foundation for studying and formulating the standard of I anal mobile communication system.
