摘要
为体现集群通信系统与公网通信系统的关键不同,本文首先介绍了数字集群通信系统的技术特点、典型网络结构和关键业务等重要信息。为了研究集群通信系统的发展,本文进一步介绍了在我国应用最为广泛的数字集群通信标准——TETRA、iDEN、GoTa和GT800。文章不仅详细分析了这些集群标准区别于其他集群标准的技术特点,而且介绍了这些标准的最新版本、最新发展状况以及今后的发展方向,分析了数字集群通信标准未来的整体发展趋势,使得数字集群领域的整体发展一目了然,具有重要指导意义。
With the purpose of revealing the differences between public communication system and digital trunking system, a detailed introduction of the characteristics, network structure and key services provided of the latter was made. For the further study of digital trunking system, we then carried out a thorough research on the four digital trunking protocols—TETRA, iDEN, GoTa and GT800—that are most widely used in China. It not only analyzed the technological characteristics of these protocols, but also introduced their latest versions, technical developments and directions of further evolution respectively, which made the present de-velopment situation of digital trunking system clear at a glance.
