基于NGN的脚本语言CPL与SCML

The Script language CPL and SCML Based on NGN

主要描述下一代网络NGN中基于XML业务脚本语言的结构与框架。我们聚焦于由JAIN论坛开发的SCML,SCML被定性为一系列NGN业务脚本语言中的一种,这类语言都可以使用户相互交流、其灵活性、开放性为其他NGNAPI功能提供便利。对比了SCML与由IETF所定义的CPL(CallProcessingLanguage)功能和要求,并发现SCML的一些优势。

In this paper we describe the architecture and framework of XML-based service scripts in NGN. We focus on the Service Creation Markup Language (SCML) Which is intended to be part of a family of NGN service scripting languages that include facilities for user interaction, mobility, and other open NGN API functions. We compare SCML to the Call Processing Language (CPL) defined by the IETF and note that SCML offers several advantages.
