基于软交换的VoIP接入系统设计实现

Design and Implementation of a VoIP Access System Based on Soft-Switch

NGN网络要求网络能够融合传统电话网(PSTN)和IP数据网,能够同时支持话音、数据和多媒体业务的传输,并采用开放的体系结构,因此NGN具有网络结构灵活并易于扩展的优点。VoIP技术就是PSTN与IP相融合的产物,而基于软交换的接入媒体网关的解决方案在该技术中具有相当重要的地位。本文讨论并设计了接入系统的整体框架,并在此基础上研究其软件实现,成功实现了将IP语音接入到软交换网络中的功能。

The most important feature of NGN is the fusion of PSTN and IP which means the supporting ability of voice, data and multimedia services. Beyond that, the flexibility and easy extended ability are also the important features of NGN for its open architecture. The solution of Access Media Gateway plays important role in VoIP technology which is the industry production based on such fusion of network. The main architecture of Access system is proposed, following the discussion of the software development. As the contribution of such work, IP voice data could be accessed into the Soft-Switch Network successfully.
