Abstract
Recently, beam hopping (BH) technology has been considered as the key technology of the next generation High Throughput Satellite (HTS) system for its flexibility. In order to ensure the communication continuity of the terminal in the beam hopping satellite system, it is particularly important to study efficient beam handover technology. This paper proposes a dynamic timeslot reservation handover algorithm based on remaining time. Firstly, the terminal obtains remaining time of terminal in the current beam position. Then this paper simulates load imbalance through Poisson random distribution, and then clusters the beam positions to calculate the probability density function of the timeslot occupied in the cluster. Finally the algorithm dynamically reserves timeslot resources for the terminal. The simulation results show that, compared with the traditional handover algorithm, when the timeslot resources are insufficient, the algorithm can dynamically reserve timeslot resources to reduce the handover failure probability, and improve QoS.
