  • A LEO global traffic model is first built, then four access and handoff strategies for LEO satellite communication are proposed, and these strategies performance, including call blocking probability and call termination probability, is evaluated through computer simulation. Based on the simple average weighted scheme, a QoS based average weighted scheme is proposed according to the characteristics of the topography and traffic density all over the world. The simulation results show that the proposed scheme can reduce Call Blocking Probability (CBP) and Call Dropping Probability (CDP) considerably.
