摘要: 基于Parlay API的第三方业务开发是下一代网络(NGN)中最为开放的业务提供方式,第三方应用程序通过Parlay API中SCF接口向底层网络协议(如SIP、INAP等)的映射来调用底层网络资源。论文重点对Parlay API中向SIP协议的映射问题进行研究,首先介绍了Parlay API和SIP的呼叫模型,接着提出了GCC SCF向SIP协议的映射模型,并设计出映射模型的程序实现流程,最后以号码翻译业务为例分析了该映射模型的工作过程。

Abstract: The 3rd party service creation parlay API-based is the most opening service provision style in next generation network,the 3rd party application programming transfers the lower layer network resource by the SCF interface defined in Parlay API mapping to lower layer network protocol(e.g.SIP,INAP etc.,).Research the problem of GCC SCF mapping to SIP protocol,introduce the call model of Parlay API and SIP,then bring forward the model of GCC SCF mapping to SIP,and design the specific program realization flow.Analyze number translate service’s process finally.

Key words: NGN, parlay API, GCC SCF, SIP, mapping
