摘　　要：针对卫星移动通信系统中对组网架构、协议体制和关键技术进行仿真论证的需求,设计了系统级仿真平台。首先介绍了系统级仿真平台架构,然后结合架构分析仿真平台的配置管理模型,对卫星、终端、信关站等核心通信节点进行建模,研究仿真平台工作流程,最后,通过多用户并发模式下随机接入过程仿真验证系统级仿真平台有效性。与传统方法相比,该仿真平台可适用于多星、多站、多波束、多链路和多用户自由组网,为卫星移动通信系统协议体制和关键技术的仿真验证提供了一种新的借鉴和参考。Aiming at the need for simulation and demonstration of networking architecture,protocol system and key technologies in satellite mobile communication systems,a system-level simulation platform is designed.Firstly,the system-level simulation platform architecture is introduced.Then,combined with the configuration analysis model of the architecture analysis simulation platform,the core communication nodes such as satellites,terminals,gateway stations,etc.are modeled so as to explore the simulation platform workflow.Finally,the effectiveness of the system-level simulation platform is verified through random access process simulation in multi-user concurrent mode.Compared with traditional methods,the simulation platform can be applied to multi-star,multi-station,multi-beam,multi-link and multi-user free networking.And this provides a new reference and guidance for the simulation and verification of protocol system and key technologies of satellite mobile communication system.
