LEO(低轨道星座)系统具有组网复杂、承载业务类型多等特点。采用基于用户行为的分层用户模型,对用户在LEO(低轨道星座)系统中的业务行为进行建模,控制用户模型的参数,生成业务流,利用网络仿真工具OPNET将业务流加载在建好的网络模型当中,对LEO系统的境外通信业务量进行分析与仿真,通过仿真得到系统的最大业务承载量,为系统的设计提供可靠依据。
Abstract：The behavior of the users in the network are modeled based on the layered user behavior model,the parameters of the user model are controlled to generate the traffic,which is loaded into modeled LEO communication system by using the network simulation software OPNET.Thus,the overseas traffic of LEO communication system is analyzed and simulated,and the simulation results can be used for system design.
