摘　　要：针对当前缺乏5G融合低轨卫星网络协议仿真与验证平台的问题,基于EXata仿真平台实现了5G融合低轨卫星网络系统级仿真平台,支持对接入与切换等关键流程的仿真。经过系统级的仿真验证,该平台可有效模拟5G融合低轨卫星网络的端到端通信与移动性管理信令流程,并给出接入时延、吞吐量等关键性能指标,为5G融合低轨卫星网络协议仿真与研究提供支撑。In response to the current lack of simulation and verification platforms specifically designed for 5G-integrated LEO network protocols,a system-level simulation platform for 5G-integrated LEO satellite networks had been implemented based on the EXata simulation platform.This platform supports the simulation of critical processes such as access and handover.Through system-level simulation verification,the platform effectively simulates the end-to-end communication and mobility management signaling processes of 5Gintegrated LEO satellite networks,and provides key performance indicators such as access delay and throughput.This platform offers support for research and simulation of 5G LEO satellite network protocols.
