摘要

下一代卫星网络将以低成本提供宽带通信。卫星技术、传输技术、天线和发射能力的最新发展使用户能够获得新一代服务,特别是当通信卫星被广泛认为是对地面系统的补充时。本文讨论了以卫星为背景的下一代卫星网络的概况。提出了未来移动系统对卫星网络的要求。第三代无线网络所采用的卫星- umts与所提出的全IP网络实现了互联。由于下一代网络系统需要高速传输和漫游能力,这种考虑是不可避免的。

A review of next generation satellite networks: Trends and technical issues
The next generation satellite networks will provide broadband communications at low cost. The recent developments in satellites technology, transmission techniques, antennas, and launch capabilities have enabled a new generation of services to be made available to users especially when communications satellites have been widely considered to complement the terrestrial systems. In this paper, a survey of next generation satellite networks through the satellite background are discussed. The satellite network requirements for the future mobile system are presented. The proposed satellite-UMTS which have been accepted for the third generation wireless network is showned to be internetworked with the proposed all IP network. This consideration is inevitable because of high-speed transmission requirements and roaming capability that the next generation network system demand.
