为了实现支持IMAP4协议的移动邮件客户端在智能手机上的应用，在VC＋＋6．0环境下，采用了高通推出的专门为无线设备设计的BREW平台。提出了原子流程的概念，以降低程序间的耦合度，提高代码复用率。经在仿真环境下测试实验，实现了与Internet上多台常用邮件服务器的交互，并且运行稳定，可作为智能手机的一个组件应用于3G网络。-In order to achieve agreement in support of IMAP4 mail client for mobile phones in the smart application, in VC++6.0 environment, used to launch Qualcomm' s wireless devices designed specifically for the BREW platform. Put forward the concept of atomic processes in order to reduce the coupling between the procedure and improve the rate of code reuse. As in the simulation environment to test the experiment, realized with more than the commonly used Internet mail server interaction, and stable operation, can be used as a component of smart phones used in 3G networks.
