5gc and satellite integrated communication scheme

5G It has the advantages of low delay and large bandwidth , However, it is difficult to cover areas with low population density due to high cost （ For example, in remote mountainous areas ） And special scenes such as polar zone 、 Ocean and airspace, etc . Compared with the ground 3G/4G/5G Wireless communication network , Satellite communication has a large coverage 、 Long communication distance 、 No environmental restrictions and other advantages .5G The complementary integration with LEO satellites can realize the full coverage of the global network .
 
IPLOOK 5G And satellite fusion communication scheme ,GEO High orbit satellites are used as data link relays ,LEO LEO satellites improve ground coverage , The satellite terminal is connected to by satellite 5G Core network ,5G The core network supports both satellite terminal access and standard base station and mobile terminal access , Realize the integration of core network . The core network uses ephemeris data , Calculate the satellite position in real time , Ensure the switching of satellite terminals 、 Paging Success Rate .
