摘要
GSM短信息通信系统提供了一个技术成熟的通信平台,其良好的开放性为用户根据公示的规范、利用集成了标准化协议和硬件接口的模块、以较低的成本快速构建网络控制系统创造了条件。针对此项应用,对短信息的通信业务性能进行了研究,通过短信息的存储转发、漫游、确认机制,分析了它的通信可靠性;介绍了短信息逻辑信道和物理信道的映射,分析了延时特性,提出了确定性和随机性时延的划分;计算了基站的短信息吞吐量;总结了短信息可提供的安全性措施,为控制系统中通信网络的选择、设计提供参考。
GSM short message service （SMS） System provides a well-rounded communication platform. The open attribute of SMS is propitious to construct the networks control system in short order with the open technical specification, standard interface and universal modules help. For this purpose, some communication qualities of service of SMS are researched. The reliability is analyzed through store and forward, roaming, acknowledgement patterns. Then time delay in communication is analyzed based on mapping between the logic channel and physical channel and a new method to classify time delay as determinate and stochastic one is brought forward. Furthermore, SMS throughputs of base station are calculated and security measures are summarized. All these parameters provide a reference to choice communication technique and design networks control system.
