摘要: 为保障移动终端在多点波束HTS (High Throughput Satellite)通信系统中的业务连续性，研究高效的点波束切换技术尤为重要。本文对HTS系统中波束切换过程进行了分段，分析了各阶段影响切换性能的主要因素，阐述了切换决策阶段中信道资源预留机制的主要原理，并提出了适用于HTS系统的波束切换动态资源预留机制。NS2平台的仿真结果证明，文中所提的动态资源预留方式可以降低系统的切换失败率，并获得较好的GoS性能。该资源预留方式及性能分析的结果对工程实际具有重要参考意义。
Abstract: Effective spot beam handover technology is essential to ensure the traffic continuity of mobile ter-minals in multi-beam high throughput satellite system. This paper divided the handover process in HTS system into three phases, analyzed the main factors that influencing the handover performance in each phase, elaborated the main principles of the channel resource reservation mechanism in the handover decision phase, and proposed an adaptive resource reservation mechanism apply to beam handover in HTS systems. The simulation results of the NS2 platform proved that the proposed adaptive resource reservation mechanism can reduce the handover failure rate of the system and obtain better GoS performance. The results of the resource reservation mechanism and performance analysis are important reference on practical application of engineering.
