基于3G的卫星移动通信系统短报文广播服务系统,通过通用性的短消息(如气象、交通等信息)按页有规律地向网络覆盖区域单向、有选择地广播发送,是实现公共信息一点对多点发送的有效手段。文章详细的分析了基于3G的卫星移动通信短报文广播服务系统的协议架构、信道设计和网元间CBS消息的传输机制,并给出了具体的实现过程。
The short message broadcast service system of satellite mobile communication system based on 3G, through the universal short message (such as weather, traffic and other information), regularly and unilaterally and selectively broadcast to the network coverage area, is to achieve public information A little more effective means of sending. This paper analyzes the protocol architecture, channel design and transmission mechanism of CBS message between satellite-based short message broadcast service system based on 3G in detail, and gives a concrete realization process.
