SMSLib例如交互式USSD会话

Question

我有一个USSD的应用程序，为用户提供了一个交互式会话，例如：

User> Dial USSD Shortcode 
Serv> Return Main Menu 
User> Select Option 1, e.g. "View Movie Times" 
Serv> Return List of Cities 
User> Select Option 3, e.g. Mumbai 
Serv> Return List of Cinemas 
User> etc ... 

我想通过使用SMSLib来模拟用户测试USSD服务器。

是否有任何示例SMSLib代码片段显示如何与USSD服务器执行交互式USSD会话？

在此link的代码给出了发送和接收使用smslib USSD数据的一个示例：

// SendUSSD.java - Sample application. 
// 
// This application shows you the basic procedure for sending messages. 
// You will find how to send synchronous and asynchronous messages. 
// 
// For asynchronous dispatch, the example application sets a callback 
// notification, to see what's happened with messages.
