    • A system and method to detect a call trigger during a call without requiring a service platform to remain connected to the call. A first communication device (106) transmits a call having call signaling and user communications. A signaling processor (112) receives the call signaling from the first communication device and selects a connection to a second communication device (108). An interworking unit (114) receives the user communications from the first communication device and converts the user communications from a time division multiplex format to asynchronous transfer mode cells that identify a selected connection to the second communication device. The interworking unit detects a call trigger in the user communications. The interworking unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the interworking unit to transport the user communications to asynchronous transfer mode cells that identify the selected connection to the thrid communication device (110) and transports the user communications to the third communication device.
    • 在呼叫期间检测呼叫触发的系统和方法,而不需要服务平台来保持与呼叫的连接。 第一通信设备(106)发送具有呼叫信令和用户通信的呼叫。 信令处理器(112)从第一通信设备接收呼叫信令并且选择到第二通信设备(108)的连接。 互通单元(114)从第一通信设备接收用户通信,并将来自时分复用格式的用户通信转换为标识到第二通信设备的所选连接的异步传输模式小区。 互通单元检测用户通信中的呼叫触发。 互通单元向呼叫处理器发送呼叫触发数据。 所述信令处理器处理所述呼叫触发数据,并且在验证所述呼叫触发时,指示所述互通单元将所述用户通信传送到异步传输模式小区,所述异步传输模式小区将所选择的连接识别到所述第三通信设备(110),并将所述用户通信传送到 第三通信设备。
