| 摘 要： | 在多协议、多用户GPS(Global Position System)/GSM(Global System for Mobile communications)监控系统中,网关的设计对系统的性能、可用性和可扩展性有重要作用.讨论了在网关设计中需要注意的几个关键问题:通过分析不同短消息服务器的接口协议,提出使用协议管理器实现多协议接入;给出了与用户系统的通信指令格式,并分析了地址的转换流程.最后剖析了用多线程方式和消息驱动实现这种系统的优点,并给出了一个具体实现的消息循环流程.实践证明这种设计是可靠高效的.

| Abstract: | Gateway design is crucial for developing a GPS/GSM supervisory system with satisfactory system performance, availability and expandability. Several related key techniques for gateway design were dealt with. After analyzing different Short Message Service Center (SMSC) interface protocols, a protocol manager was introduced to achieve multi protocol capability. Custom communication instruction format was proposed. The address conversion procedure was discussed in detail. Advantages of multi thread and message driving in software architecture were also presented. The reliability of the gateway design strategy was proved by a practical implementation with the proposed techniques. |
