AI Technical Summary

Technical Problem

Existing low-Earth orbit satellite IoT resource allocation methods are difficult to adapt to the dynamic channel changes when a large number of terminals access the network, resulting in low access success rate and reduced spectrum utilization efficiency.

Method used

Three spatial anchor points are set up within the coverage area of ​​the low-Earth orbit satellite beam to generate a dynamic coverage characterization model. By fusing channel measurements with predicted states, resource allocation strategies are optimized and transmission strategies are adjusted in real time to adapt to channel changes.

Benefits of technology

It improves resource utilization and link transmission stability, accurately captures channel time-varying characteristics and spatial non-uniformity, and enhances the overall service performance of low-orbit satellite IoT terminal access.

Abstract

本发明提供物联网低轨卫星海量终端接入的资源分配生成方法及系统，涉及数据处理技术领域，所述方法包括：基于动态覆盖表征模型所反映的信道空间变化梯度，计算得到策略优化向量；基于策略优化向量对初始传输策略进行调整，生成优化决策规则；基于优化决策规则为终端确定资源分配方案，并基于资源分配方案生成资源分配指令；基于资源分配指令完成参数配置并发起上行数据传输，生成链路性能数据；基于链路性能数据判断三个空间锚点界定的覆盖扇区是否满足预设性能门限，若不满足则触发对相应空间锚点的实测信道参数重新采集及资源分配策略的更新。本发明可有效提升海量物联网终端接入的资源利用率与链路传输稳定性。
