摘要	LEO satellite communication systems have the characteristics of high-speed and periodic movement. The handover of user link occurs frequently, which has a serious impact on user terminal application and system capacity. To address this issue, we propose a handover strategy of LEO satellite user terminal based on multi-attribute and multi-point (MAMP) cooperation. Firstly, the satellite-user-time matrix is established by using the satellite constellation coverage and handover model. Then, combined with the visual time and signal quality, the user access matrix and satellite load matrix are extracted to determine the weight equation of the handover strategy with the channel reservation. According to the system modeling simulation, the algorithm improves the handover success rate by 2.5%, the lasted call access success rate by 3.2%, the load balancing degree by 20%, and the robustness by two orders of magnitude.
