Abstract

With the continuous evolution of 5G technology, the integration of satellite communication network into global 5G network has been put on the agenda. LEO Satellite Constellation with its advantages of low delay and global coverage can form an effective supplement to the ground 5G mobile communication system, and provide infrastructure support for various services based on broadband access and Internet of things. It is an important direction of future communication development, and also a hot spot. However, with the development of study on 5G NTN (Non-Terrestrial Networks) network, due to the characteristics of high-speed mobile satellites and dynamic topology changes of LEO constellation, the problem of network integration between LEO constellation and 5G ground system becomes more and more prominent. According to the network characteristics of LEO constellation, the key technologies of network architecture, inter satellite routing and mobility management of LEO constellation based on 5G are studied in this paper, which can provide guidance for the networking design and engineering practice of LEO constellation networking based on 5G.
