WAP网关是整个移动互联网系统中的核心部分,它负责无线网络协议与WWW协议之间的转换。文中提出在Linux操作系统下使用多线程的状态机处理模块统一处理各WAP功能模块的实现方案,包括承载网络模块、WAP协议栈模块、WAE模块与管理模块,并实际搭建出WAP网关,满足本设计提出的各项功能,具有高效性、可维护性和可扩充性。 WAP gateway is the core part of the entire mobile Internet system, which is responsible for the conversion between the wireless network protocol and the WWW protocol. In the paper, we propose a solution to handle all WAP functional modules in a Linux operating system using multi-threading state machine processing module, including bearer network module, WAP protocol stack module, WAE module and management module, and actually set up a WAP gateway to meet this Design proposed features, with high efficiency, maintainability and scalability.
