摘要/Abstract

摘要： 针对低轨卫星通信轨道高度低、运动速度快、切换频繁的特点以及业务类型和用户类型逐渐丰富的发展趋势，提出高业务量下基于差分进化算法的自适应信道预留策略，动态调整信道预留数目，保证高优先级用户的及时接入;低业务量时提出非预留信道分配方案，满足高优先级用户的理想带宽需求，充分利用系统的信道资源.小区信道全部被占用时，提出增强型排队策略，令暂时无法接入的用户加入排队序列，根据综合优先级依次接入，进一步提升用户体验和系统整体性能.实验证明，该方案可有效提高系统资源利用率，保障各类用户的体验，使系统整体服务质量更佳.

关键词: 低轨卫星通信, 信道预留, 非预留信道分配, 增强型排队

Abstract: For the low earth orbit satellite communication， in view of the characteristics of low altitude， fast speed and frequent switching， single channel allocation strategy cannot improve the experience of more users and the utilization of channel resources under a low traffic scene. The adaptive channel reservation strategy based on differential evolution algorithm for high traffic conditions is proposed， which dynamically adjusts the number of channel reservation to ensure the timely access of high priority users. For low traffic， the non-reserved channel allocation scheme is put forward to meet the ideal bandwidth requirements of high priority users and to make full use of the channel resources of the system. In addition， to further improve the user experience， taking into account the comprehensive priority， the enhanced queuing strategy allows users that are unable to access to join the waiting queue temporarily when all the cell channels are occupied. Experiments show that the scheme can effectively improve the utilization rate of system resources and guarantee the quality of service of high priority and user experience， and make the whole system service quality better.

Key words: LEO satellite communication, channel reservation, non-reserved channel assignment, enhanced queue
