利用开源VoIP技术建设NGN业务平台的应用研究

摘要

Open-source VoIP technologies can be employed to setup VoIP platforms by deploying open-source software on x86 servers, which have many advantages such as low cost, flexibility and openness. The usage of open-source VoIP technologies in NGN service platform deployment helps to reduce carrier's investment, shorten service deployment cycle and improve the duplicability of service platform. In the paper, the architecture of NGN service platform deployed by open-source VoIP technologies is proposed based on comprehensive survey and detailed analysis. A typical example is also provided to evaluate the feasibility and advantages of the proposed NGN service platform deployment method.%开源VoIP技术是一种利用开源软件部署在x86服务器上形成专业VoIP平台的解决方案,具有低成本性、高可用性、灵活性和开放性的优势.利用开源VoIP技术建设NGN业务平台能很好地解决目前运营商建设方式中建设维护成本较高、新业务部署周期较长、可复制性不高的问题.本文在全面分析开源VoIP平台解决方案的基础上,结合电信运营商业务平台的现状,深入研究了开源技术在电信运营商业务平台建设中的应用,提出了利用开源VoIP技术构建NGN业务平台的架构,给出了一个实现范例,评估了利用开源VoIP技术构建NGN业务平台的可用性和优势.
