Non-Terrestrial Network Core Network: Technical Challenges and Countermeasures
The integration of space, aerial, and terrestrial communications has become a major trend in the development of 5G-Advanced and 6G. As a key technology for seamless global coverage, Non-Terrestrial Networks (NTN) provide wide-range communication services through LEO satellites. However, the high-speed movement of satellites, long-distance transmission, and incompatibility with traditional core network architecture have brought serious technical challenges.
