Description

technical field [0001] The invention relates to the technical field of satellite mobile communication, in particular to a system-level simulation platform and construction method for satellite mobile communication. Background technique [0002] With the successful deployment of 4G in global commercial use, user demand has shown explosive growth in recent years. In order to meet the growing user demand, the field of wireless communication has also accelerated the research progress and achieved phased results. However, the ground mobile communication system still has deficiencies while meeting the rapidly increasing demands of urban users. In scenarios such as emergency relief, forestry inspection, outdoor exploration, power inspection, marine fishery, and village communication projects, the ground communication system cannot guarantee user needs in these situations due to factors such as high coverage costs or no coverage at all. However, satellite mobile communication can s...
