1、四川大学博士学位论文USSD网关设计与实现姓名:汪洁申请学位级别:博士专业:计算机应用技术指导教师:李志蜀20030430最后本文给出了用C语言在RedHatLintLx7.2平台上的USSD网关实现,并将USSD网关的实现按照各个功能模块分别做出了详细的论述。整个USSD网关的业务逻辑以USSD消息队列平台作为基础,该平台主要负责容纳所有经过USSD网关的数据包:USSD网关的处理逻辑首先将从队列中获取这些数据包并根据包的类型做相应的处理,这~系列的处理由USSD网关的路由、门户导航、计费等模块来完成;当USSD网关在完成以上处理之后需要将各个方向的包发送到
2、其目的地、需要专门负责建立网络连接以及完成网络读写操作,该功能由通信代理模块来完成;此外,我们设计实现了日志以及安全检测处理模块来对USSD网关的业务逻辑进行维护和管理。USSD网关的设计和实现,很好的满足了将移动通讯网和互联网相结合的需求。同时开辟了无线接入互联网的一种全新的解决方案,事实证明是可行的。目前,我们设计并实现的USSD网关1.0版本在重庆移动经过了试运行阶段,目前正式投入商业运营。关键词:USSD网关路由计费门户导航TheDesignandimplementationofUSSDGatewayMajor:ComputerApplicationG
