Multi-objective low earth orbit satellite handover based on deep reinforcement learning
针对低地球轨道(LEO)卫星高速运动导致用户需频繁切换接入卫星,增加了系统开销与信令负载,同时其动态拓扑及用户高速移动也加剧了移动性管理的复杂性,文中提出一种基于人工智能的卫星切换优化策略,综合最小化切换次数与卫星响应时间、最大化系统吞吐量,利用深度强化学习实现智能决策.该方法构建结合信噪比、服务时长及响应时间的多维奖励函数,并引入长短期记忆网络增强时间建模能力.仿真结果表明,该策略在不同用户规模与场景下均优于现有方法,显著降低了切换次数与失败率,同时提升了系统吞吐量,验证了其在提升通信连续性与系统稳定性方面的有效性.
The high-speed movement of low earth orbit(LEO)satellites causes users to handover satellites frequently,which increases system overhead and signaling load.Meanwhile,the dynamic network topology and high user mobility further complicate mobility management.In view of the above,this paper proposes an AI-based satellite handover optimization strategy that integrates minimized handover frequency,satellite response time,and maximized system throughput.The deep reinforcement learning is used to realize intelligent decision.The method constructs a multidimensional reward function combining signal-to-noise ratio(SNR),service duration and response time.In addition,the long short-term memory(LSTM)network is introduced to enhance the capabilities of temporal modeling.Simulations show that,in the case of different user scales and scenarios,the proposed method outperforms existing approaches in improving throughput and reducing handover frequency and failure rate,which demonstrates its effectiveness in ensuring communication continuity and system stability.
