摘要
Abstract
The Low Earth Orbit(LEO)satellite network has been widely used in emergency communication,intelligence investigation,disaster rescue and other fields due to its low orbit height,small transmission delay and seamless coverage all day and all weather on a global scale.However,due to the high-speed relative motion between LEO satellites and user terminals,frequent handover problems occur.As a key link in handover,handover decision directly affects the success and performance of handover,and is an important prerequisite for achieving reliable and smooth handover.Based on the research progress of LEO satellite network handover decision methods,two types of handover decision methods based on single attribute decision-making and multi-attribute decision-making are summarized;the commonly used graph theory model handover decision methods are summarized;the application of machine learning in LEO satellite network handover decision is summarized;meanwhile,a comparative analysis is conducted on different handover decision methods based on commonly used performance indicators.Finally,prospects for future research on LEO satellite network handover are presented,providing solutions for related studies in the future.关键词
