摘要/Abstract

摘要：

随着5G的商用，卫星通信与地面5G的融合已成为业界研究的一个重点方向。低轨卫星网络能够覆盖全球，实现任何时间、任何地点与任何人通信，是地面蜂窝网络的有效补充和扩展，尤其是OneWeb、Starlink等低轨卫星互联网星座的推进部署，加速了低轨卫星网络的发展。但是由于低轨卫星具有高动态性，其网络拓扑变化速度快，由此引发的网络管理问题成为低轨卫星应用的难点，而移动性管理又是其中的关键技术，如何构建适用于高动态低轨卫星网络的移动性管理机制是一个亟待解决的问题。基于地面分布式网关和卫星代理簇的思想，提出动态虚拟化分布式移动性管理模型，主要解决传统移动性管理的扩展性差、单点失效等问题，同时利用卫星组建虚拟网关解决在地面上建立卫星地面站困难的问题。

Abstract:

With the commercialization of 5G,the integration of satellite communication and ground 5G has become a key research direction in the industry.Low earth orbit satellite network can cover the whole world and communicate with anyone at any time and anywhere.It is an eff ective supplement and expansion of terrestrial cellular network.Especially,the deployment of low earth orbit (LEO) internet constellation such as OneWeb and Starlink accelerates the development of LEO satellite network.However,due to the high dynamic of LEO satellite and the fast change of its network topology,the network management problem caused by it has become the diff culty of LEO satellite application,and mobility management is one of the key technologies.How to build a mobility management mechanism suitable for high dynamic LEO satellite network is an urgent problem to be solved.Based on the idea of ground distributed gateway and satellite agent cluster,the dynamic virtualization distributed mobility management (DV-DMM) model was proposed,which was mainly used to solve the problems of poor scalability and single point failure of traditional mobility management.At the same time,it used satellite to build virtual gateway to solve the problem of building satellite ground station on the ground.

Key words: LEO satellite, distributed gateway, virtualization gateway, mobility management
