摘要
卫星网络因为具有覆盖范围广、传输可靠性高等特点,已经成为了天地一体化信息网络重大工程项目的重要组成部分。卫星的高速移动性和其与地面终端之间的频繁切换特性对于移动性管理技术提出了必然要求,现有移动性管理技术主要参考地面蜂窝网中已有相关技术。首先简述了传统移动性管理技术应用于卫星网络的相关成果,然后从位置管理、切换管理等方面分别对已有研究成果进行了回顾和介绍,最后对下一步研究方向进行了展望。
Satellite network has become an important part of the major engineering project of space-integrated-ground information network due to its wide coverage and high transmission reliability.The high-speed mobility of satellites and the frequent handover characteristics between satellites and the ground terminals put forward inevitable requirements for mobility management technology.The existing mobility management technology mainly refers to the existing related technologies in the ground cellular network.Starting with brief description of the related achievements of the traditional mobility management technology applied in satellite networks,this paper reviews and introduces the existing research results from the aspects of location management,handover management,etc.,and finally gives prospects of the next research direction.
