摘要
研究了智能网和 IP网融合所需的呼叫模型 ,以支持基于 Vo IP建议的多媒体业务 .分析了现有智能网呼叫模型在 IN/ IP综合中的局限性及其原因 ,基于分层原则独立提出了满足 Vo IP信令需求的增强型智能网呼叫模型 ,并给出了增强后的智能网呼叫模型与典型的 Vo IP信令—— H.32 3建议之间的集成方式 .
With the fast development of H.323-based IP telephony in recent years, the study of integration between the intelligent network (IN) and IP network is becoming a spot. We firstly investigate the principle of the integration of IN and IP,and analyze the disadvantages of existing IN basic call model to support VoIP call and the reason?Then we propose an enhanced call model based on layered structure in order to fully exploit the advantages introduced by VoIP signaling and illustrate the integration of the enhanced call model and a typical VoIP signaling-H.323 Recommendation.
