摘　　要：本文在对IN和OSA/Parlay体系结构进行深入研究的基础上,分析了IN和OSA/Parlay在网络功能上的相似性,提出了用IN平台实现Parlay网关的新思路,即用SIB编写业务逻辑程序的方法实现标准的Parlay接口类,为IN平稳过渡到Parlay开放架构提供了参考,并研究了业务逻辑程序和接口类的对应关系。然后本文以两个典型的应用为例,阐述了业务逻辑程序的启动、服务以及实例销毁的全过程。Firstly after a lot of study in the architecture of IN and OSA/Parlay, their similarity of functional characteristic in network is analyzed completely. Then a new way to implement OSA/Parlay based on IN platform is proposed： what is meant is that the standards Parlay APIs can be realized through the way of constructing SLP （service logic program） with SIB （service independent block）. Furthermore it is studied that the corresponding relationship of the granularity of SLP and Parlay interface. Finally, two typical applications are taken as examples, the sequences of SLP instance created, served and destroyed are described in details.
