Abstract :
The cell layout and relative satellite-user motion direction decide the variant cell motion patterns, which result in different handover relationship between cells for users in low earth orbit (LEO) satellite systems, and directly affect the performance of handovers for users. User mobility models were developed for two typical cell motion patterns. Mobility parameters such as cell dwell time, handover probabilities and average number of handover requests were analyzed and simulated. With comparing the impact of cell motion patterns on user´s handovers, the more applicable cell motion pattern is proposed for LEO satellite with small beam overlap areas, which can be reference for spot-beams coverage planning
