摘　　要：在中轨卫星移动通信系统中 ,确定小区驻留时间分布对于合理地规划切换策略具有十分重要的意义。文中指出了地球固定覆盖与卫星固定覆盖两种方式下小区驻留时间分布不同的原因。提出一种仿真计算卫星固定覆盖方式下小区驻留时间分布的方法 ,得出了数值结果 。In MEO(Medium Earth Orbit)satellite mobile communication systems,the confirmation of cell dwell duration's distribution is very important to constitute handoff strategies properly.The reason of the difference between earth fixed coverage and satellite fixed coverage is pointed out.A simulation method by which cell dwell duration could be obtained in satellite fixed coverage instance is provided,and numerical results are obtained and compared with that in earth fixed coverage instance.
