基于WSAAsyncSelect模型的GPRS服务端程序设计

Design for GPRS Server-Side Program Based on WSAAsyncSelect Model

简要介绍了GPRS通信的基本原理以及在自动化监测系统中的应用情况。详细描述了基于WSAAsyncSelect网络套接字模型的GPRS服务端程序架构和关键实现代码,对使用该模型设计的GPRS服务端程序的大数据量并发测试结果表明,WSAAsyncSelect模型的性能可以应付至少1000个GPRS终端的数据并发,满足中小规模自动化监测系统基于GPRS通信的需求。

The basic principle of GPRS communication and the applications in the aumtomatic monitoring system are briefly introduced.The architecture and key implementation code of GPRS server-side program based on net socket model of WSAAsyncSelect are described in detail.The test results of mass concurrent data for the GPRS server program based on this model prove that the performance of WSAAsyncSelect is powerful enough to cope with the concurrent data of at least 1000 GPRS terminals,which meets the needs of GPRS communication of automatic monitoring system in medium and small scale.
