En raison de la différence significative de vitesse entre les terminaux utilisateurs (UT) et les satellites en orbite terrestre basse (LEO), il est nécessaire de résoudre le problème des transferts fréquents de UT au bord des faisceaux satellites en mouvement. En outre, avec le développement des communications par satellite LEO, l'échelle des constellations et le nombre d'UT connaissent une augmentation massive. Ainsi, dans cet article, une stratégie de transfert de satellite est proposée pour améliorer les performances de transfert des UT et des satellites. Nous définissons conjointement la fonction d'utilité du handover en considérant la qualité de l'expérience des UT, le débit des satellites et l'équilibrage de charge du réseau. Ensuite, une méthode de codage est proposée pour représenter les combinaisons d’UT et de satellites. Pour réduire le coût de calcul, une stratégie d'accès et de transfert basée sur un algorithme heuristique est proposée pour rechercher le résultat de transfert optimal. Enfin, des simulations montrent l'efficacité et la supériorité de la stratégie proposée.

Abstract: Due to the significant difference in speed between the user terminals (UTs) and the low earth orbit (LEO) satellites, it is necessary to solve the frequent handover of UTs at the edge of the moving satellite beams. Besides, as the development of LEO satellite communications, the scale of constellations and the number of UTs undergoing massive increase. Thus, in this paper, a satellite handover strategy is proposed to improve the handover performances of UTs and satellites. We define the utility function of handover jointly by considering the quality of experience of UTs, the throughput of satellites and the load balancing of network. Then, a coding method is proposed to represent the combinations of UTs and satellites. To reduce the calculational cost, an access and handover strategy based on a heuristic algorithm is proposed to search the optimal handover result. Finally, simulations show the effectiveness and superiority of the proposed strategy.
