| Abstract: | The emergence of the Internet of Things（IoT） has a profound impact on people’s lives and working methods. However, it cannot achieve global coverage, LEO satellites can make up for its disadvantages properly and expand the coverage of the IoT greatly. The paper analyses the architecture of the satellite mobile communications network and the ground IoT. Then, it provides an overview of the architecture of the LEO satellite constellation-based IoT including the following topics：LEO satellite constellation structure, system components, transmission system and network architecture. |
