| 摘 要： | 我国行业专网的电话网目前绝大部分仍是传统的PSTN网络。PSTN网络经过多年运行,存在“设备老化、故障率高、新业务支持力度不够、部分设备逐步停产”等诸多问题,面临转型。行业专网PSTN网络向IMS网络的迁移演进已经成为大势所趋,本文对此分用户迁移类别、分场景进行阐述研究,希望能对相关行业专网的演进具有一定的借鉴意义。

| Abstract: | The majority of the industry private telephone network in our country is still the traditional PSTN network at present. After years of operation, PSTN network has many issues, such as "equipments aging, high failure rates, not enough support for new services, part equipments off line gradually", and results in transition. From PSTN to IMS, the migration and evolution for industry private telephone network has become the trend. It is studied by user migration categories, by scenarios in this article, which will has a certain reference significance for the evolution of industry private network. |
