摘要
随着国家电网公司行政交换网演进方向采用IMS技术体制,IMS行政交换网的建设面临着核心网、承载网、接入网等一系列建设规划研究工作。将来总部及各省公司IMS交换网之间以及与公网运营商的互联互通及各单位的号码资源分配问题,涉及号码变换设计。通过对国家电网行政交换网现状调研及对IMS关键技术、架构进行研究,结合电力专网的特点,提出了公司IMS行政交换网号码变换设计方案,为公司交换网整体有序演进提供技术指导。
With the adoption of IMS technology system, the construction of IMS administrative switching network faces a series of planning research such as core network, bearer network, access network and so on. The problems of interconnection between headquarters and IMS network of provincial companies and public network, and the problem of telephone number resource allocation involves number transformation design. Based on the investigation status of State Grid administrative switching network, and the analysis of key technologies and architecture of IMS, combined with the characteristics of the electric power network, the transformation number design for IMS administrative switching network was presented, technological guidance was provided for the orderly evolution of switching network.
