针对信关站协议一致性分析和压力测试的需求,设计了信关站信令分析系统.通过抽象物理层、提供终端和信关站信令交互接口的方法,实现了终端和信关站高层信令级交互,协助信关站进行协议一致性开发与验证.通过ZeroMQ的多播协议,实现了大规模模拟终端接入信关,进行信关站压力测试.实验表明,该设计方案能有效通过多个模拟终端触发信关站的协议处理功能,从而支持开发者进行信关站的信令分析和压力测试.%Aiming at the requirements of protocol consistency analysis and stress test of gateway station, a signaling analysis system is designed. By abstracting the physical layer and providing the interaction interface between terminal and gateway station, the high-level signaling interaction between the terminal and the gateway station is realized, thus to assist gateway station in doing protocol-conformance development and verification. Through the ZeroMQ multicast protocol, large-scale analog terminal access to the gateway station is implemented to conduct the stress testing of the gateway station. The experimental results indicate that the design scheme can effectively trigger the protocol processing function of the gateway through multiple analog terminals, thus supporting developers in conducting signaling analysis and stress testing of the gateway station.
