摘　　要：USSD(Unstructured Supplementary Service Data,非结构化补充业务数据)是一种基于GSM移动通信网络的新型交互式数据业务,与短消息相比,具有响应速度快、交互能力强、可靠性高的特点。首先分析了USSD对话的信令流程,然后从提高信令的并行处理能力出发,提出了USSD对话有限状态自动机的实现方法。USSD（ Unstructured Supplementary Service Data） is a type of interactive data service based on the GSM mobile network. Compared with the SMS, the service has more special characteristics such as high speed of response, strong interactive ability, high reliability and so on. Firstly the Signaling flow of USSD dialogue was analyzed, aiming at improving the parallel processing ability of Signaling. Then the implementation method of finite state automaton on USSD dialogue was brought forward.
