一种基于XML的综合话音业务描述语言

Voice services under NGN environment impose a great deal of variety, compellability and time-to-market stress on new services development. However, traditional voice services system are usually implemented on proprietary hardware and software platforms, which causes service development technology lack of portability, extensibility, and reusability. This paper descries a proposed XML-based integrated voice service description language. The language abstracts the common service entities and describes them in XML format. Additionally, it provides declarative event handling and external systems integration mechanisms.
