[en] The reduced latency and ubiquitousness of NGSO satellite systems make them an attractive option for the high-speed broadband services when comparing
to terrestrial networks. However, due to the spectrum shortage problem in satellite communications, NGSO operating gateway (GW) feeder links and user terminal (UT) links are sharing the same frequency bands. Interference becomes then a critical concern, especially when UTs are situated in close proximity to GWs. Motivated by this interference issue, we investigate satellite hand-over to reduce the interference between GW and UT in this work. Through empirical analysis and simulations, our work sheds light on the feasibility and efficacy of employing satellite hand-overs to enhance the overall performance of NGSO-based communication networks under the spectrum sharing between Gws and UTs.
