【摘要】：移动卫星网络因具有覆盖区域广、通信延时低等优势受到广泛关注,当前有大量研究旨在开发IP协议的组网技术,并将其与地面IP网络融合。融合网络的挑战之一,即为卫星移动性,用户在卫星网络中的接入点频繁切换导致移动管理问题,而现有的移动IP技术不能高效支持卫星网络移动切换。为了高效支持移动切换,在卫星网络中应用标地分离思想,在标地分离的架构下研究切换管理问题;用映射服务系统对终端进行位置管理,在移动切换中由新接入卫星网关和终端的标志为主要信息在原卫星中形成通告转发表。仿真结果表明,相对移动IP技术,该方法有明显优势。将其应用于卫星网络时可以降低切换延时,减少大量的绑定更新开销或是次优路由,提升系统的性能和可扩展性。
[Abstract]:Mobile satellite network has been paid more and more attention because of its wide coverage area and low communication delay. At present, there are a lot of research aimed at developing the networking technology of IP protocol and integrating it with the ground IP network. One of the challenges of integrated network is satellite mobility. Frequent handover of access points in satellite networks leads to mobile management problems, but the existing mobile IP technology can not efficiently support mobile switching of satellite networks. In order to support mobile handover efficiently, the switching management problem is studied under the framework of landmark separation by applying the idea of landmark separation in satellite network, and the position management of terminal is managed by mapping service system, and the notification forwarding table is formed in the original satellite with the main information of new access satellite gateway and terminal as the main information in mobile switching. The simulation results show that this method has obvious advantages over mobile IP technology. When it is applied to satellite network, it can reduce the handover delay, reduce a large number of binding update overhead or suboptimal routing, and improve the performance and scalability of the system.
