摘要
随着IMS技术在运营商网络及企业专网中的成熟应用,IMS业务开发部署成为了当前领域的研究热点。为实现IMS行政交换网业务的标准开发和灵活部署,文章分析和对比了基于SIP AS和基于OSA的2种业务开发模式,提出了适用于企业IMS专网的业务开发实现方法,并根据可靠性要求提出了3种业务部署方案,分别满足不同可靠性要求的企业IMS业务实际部署场景。文章提出的方案在国家电网公司IMS行政交换网中进行了实际业务开发和运行环境部署的论证。
With the mature deployment of IMS technology in operator network and enterprise intranet, the development and deployment of services in IMS become a research hotspot. In order to realize the standard development and flexible deployment of services in the IMS administrative switching network, this paper analyzes two construct models of IMS service based on SIP AS and OSA, and then presents the scheme for service development for the IMS intranet. Considering the different reliability requirements, we propose three service deployment schemes, which can mostly satisfy different reliability requirements in the actual deployment scenarios. The schemes proposed in this paper have been demonstrated in the IMS administrative switching network of the SGCC.
