LEO卫星网络切换协议中的路由选择策略应当综合考虑路由本身优化性,路由计算复杂性,路由更新的信令代价。提出适合LEO网络卫星切换要求的动态混合路由选择策略(DHRS:DynamicHybridRouteSelection),即发生卫星切换时,由卫星节点根据移动终端用户切换前所处位置和切换前路由表等信息,为移动终端选择合适的路由。 The routing strategy in the LEO satellite network handover protocol should take into account the optimization of the route itself, the complexity of route calculation and the signaling cost of route update. A Dynamic Hybrid Routing (DHRS) method is proposed which is suitable for LEO network satellite switching. That is, when a satellite handover occurs, the satellite node selects the suitable mobile terminal from the information such as the location before the handover of the mobile terminal user and the routing table before the handover The route
