在Windows Mobile上监听Radio Interface Layer Notification

RIL（Radio Interface Layer）工作在手机的底层，负责数据传输、AT指令的发送、接收及解析、提供网络支持，支持上层通讯应用程序的SMS、Voice Call等。可以说，RIL是手机通信系统的软件层面的最底层。

如果我们想监听手机上的通讯活动，比如说想记录用户什么时候给那个号码拨打了电话，什么时候开始呼叫，什么时候开始建立会话进行通话，什么时候挂的电话（谁挂的），以及更详细一点的信息，例如手机都通过了哪些基站……这些信息都可以拦截RIL层的消息来得到。

本程序就是一个例子。当然，只是个示范程序，实现了最基本的监听，想要得到进一步详细的信息，只需对监听来的消息进行进一步解析即可。
