Abstract

The integration of satellite-based Non-Terrestrial Networks (NTN) with terrestrial communication infrastructures introduces significant challenges, especially in coping with the unpredictable nature of traffic generated by end users. Traditional scheduling approaches in satellite systems often assume deterministic traffic models, limiting their effectiveness in dynamic and data-driven scenarios. This paper presents a framework for integrated NTN operations that incorporates stochastic traffic modeling into satellite scheduling, enabling a more flexible and realistic approach to resource management in NTNs. By leveraging statistical traffic models based on the central limit theorem, the proposed method accounts for traffic uncertainty and embeds it directly into the scheduling process. A key concept introduced is schedule certainty, which quantifies the reliability of a schedule under uncertain input conditions and serves as both a decision variable and an optimization parameter. This novel approach is exemplified through the Constellation Management System framework, extended with a data generation uncertainty model to showcase its practical implementation and benefits. Results demonstrate that probability-aware scheduling achieves a tightly controlled certainty level aligned with operator-defined thresholds, providing higher certainty levels for equivalent performance metrics. This allows satellite operators to dynamically adjust service coverage and system efficiency, accounting for varying levels of traffic uncertainty. This work highlights the importance of probability-aware scheduling in enabling more robust and efficient operation of future satellite-terrestrial hybrid networks.
基于概率感知的TN-NTN综合作战卫星星座调度
基于卫星的非地面网络(NTN)与地面通信基础设施的融合带来了重大挑战,特别是在应对最终用户产生的不可预测的流量方面。传统的卫星系统调度方法通常采用确定性交通模型,限制了其在动态和数据驱动场景下的有效性。本文提出了一个集成NTN操作的框架,该框架将随机交通建模纳入卫星调度,使NTN中的资源管理方法更加灵活和现实。该方法利用基于中心极限定理的统计交通模型,考虑了交通不确定性,并将其直接嵌入调度过程中。引入了调度确定性这一关键概念,它量化了在不确定输入条件下调度的可靠性,既是决策变量又是优化参数。通过星座管理系统框架对这种新方法进行了举例说明,并用数据生成不确定性模型进行了扩展,以展示其实际实施和效益。结果表明,概率感知调度实现了与操作员定义的阈值一致的严格控制的确定性水平,为等效性能指标提供了更高的确定性水平。这使得卫星运营商能够动态调整服务覆盖范围和系统效率,以应对不同程度的通信不确定性。这项工作强调了概率感知调度在实现未来卫星-地面混合网络更稳健和高效运行中的重要性。
