摘要
DVB-RCS2是一种新型宽带卫星接入技术,大量应用于交互式卫星通信系统中。目前,DVB-RCS2的正式标准已颁布,受到了业界的广泛关注。首先,介绍DVB-RCS2的通信网络拓扑,描述了不同类型网络拓扑的组成与功能。其次,重点讨论回传信道卫星终端接入和退出网络的流程,分析了每个阶段的目的和意义,并对信令传递过程进行说明。最后,对DVB-RCS2与DVB-RCS的技术特点进行比较分析,指出了DVB-RCS2的改进与提升。
DVB-RCS2,as a new access technique of broadband satellite, is widely used in interaction satellite communication system. At present,the official standards of DVB-RCS2 is promulgated, and for its fairly high military application value, receives great attention from the industry. Firstly, the communication network topology of DVB-RCS2 is presented, the composition and function of various network topologies expounded. Then the access and logoff procedures of return channel satellite terminal are emphatically discussed, the purpose and significance of each stage analyze, and the signaling transfer process described. Finally, the technical characteristics of DVB-RCS2 and DVB-RCS are compared and analyzed, and the improvement and promotion of DVB-RCS2 pointed out.
