摘　　要：CDMA增强型数据业务采用虚拟专用拨号网技术,为用户提供基于高速分组数据网络之上的VPN数据专网,VP-DN为分支点建立连接到企业内部的私密隧道,即两层隧道协议。基于隧道可以实现企业内部数据安全,高速、便捷的传输;从而使企业用户在任何地点都能够通过CDMA网络无缝和安全的连接到企业内网,实现信息共享、交互和相关业务应用的处理,节省了用户的通信成本,提高了企业管理运作效率。文中着重阐述了EVDO动态VPDN相关技术原理,组网方式,并对其安全性进行了分析,其次介绍了EPOS交费平台的系统组成以及如何利用CDMA EVDO动态VPDN技术实现在EPOS交费平台进行交费、充值、售卡等事务处理,主要目的是解决农村信息化的问题。CDMA EVDO business is used VPDN technology to provide users with the VPN data private network based on high-speed packet data network. VPDN for branch point to enterprise internal connection is established by tunnel technology. Based on the tunnel, it can realize enterprise internal data security, high-speed, convenient transmission;Thus the enterprise users in any place through the CDMA network seamlessly and safely connected to the enterprise internal network, realize the information sharing and interactive and related business application processing, save the user＇s communication cost and improve enterprise management operation efficiency. It expounds the dynamic EVDO VPDN related technical principle and networking methods and adopted the technical scheme and implementation process in engineering practice. The main purpose is to solve the problem of rural informatization service in telecom domains.
