摘要
文章探讨了在3GPP IMS与PSTN互通的过程中SIP与ISUP两种不同的协议数据单元之间的转换问题。提出了实现转换的机制,定义了两种不同的协议数据结构,重点研究基于ISUP数据单元格式的两种协议数据的转换方法,并给出了具体的流程图,实现了相互的转换。
This paper explores the conversion between two different protocols, SIP and ISUP, in the process of the interworking of IMS and PSTN in 3GPP, proposes the mechanism for implementing conversion, and defines two different protocol data structure, and focuses on the study of the conversion methods for the two protocol data based on ISUP data unit format. The specific flow chart is given and the conversion between each other is realized.
