    LEO satellite communication network includes two kinds of architectures, namely “Star-Ground based network” and “Star-Space based network”. Compared with the ground communication, it has advantages of wide coverage, low cost and fast deployment, while compared with the traditional high earth orbit satellite communication, it has unique features in the overall layout, transmission mode, coverage characteristics and topology structure. And it has great potential in global communications and Internet access, 5G, the IoT, and aerospace industry, as well as the application of military capabilities in space. Not only is it become the arena of commercial space technology, but also become the new area of space and military strategic competition of some major powers, which has triggered the active engagement of more space countries and enterprises. The competition among space countries in the field of LEO satellite communication network is fierce, showing the dynamics of “the United States dominating and other space countries accelerating to follow”. The deeper motivation behind it is to seize the orbit-frequency resources, compete for the first-mover advantage and prepare for national security. To participate in the fierce international competition of LEO satellite communication network , China can make peaceful development and use of LEO space and strive to provide first-class Chinese products and services from four aspects, namely, the distribution of medium and low earth orbit and the frequency resources, the development of low-cost space technology, the optimization of commercial space development model and the strengthening of multi-party cooperation in the international community.
