【摘要】：电信业务和互联网业务正在趋于融合化,彼此之间的竞争关系也越来越明显,对互联网和传统通信的要求也不能与以往相比。在通信服务的能力和质量上有着更严格的需求,传送的速度也有着很大的提升。IP多媒体子系统(简称IMS)被认为是未来的主要通信技术,无锡联通将固网用户进行IMS改造列入计划。论文首先介绍研究背景、研究意义以及国内该课程研究的情况。研究与无锡联通现有固定网络的现状相结合,以固定网络的改造为基础,总结存在的问题,与现有固网互通,提出IMS网络的构建方案。方案主要包含IMS总体结构、网络规模预测、网元设置以及容灾方式等方面的内容,提出IMS网络部署方案诸如路由互通、网络承载、编号地址、IP分配、计费以及网管等。无锡联通先对业务支撑能力较弱的软交换网络上的用户进行改造,即NGN用户。后逐步改造PSTN网络上的数字中继和普通固网用户。该工程在无锡联通分阶段施工,最终证明方案是可行的。目前江苏联通IMS在线注册用户已达65000多户。本文的研究成效有利于固定语音网络的未来发展,为IMS如何提供统一的业务平台提供了参考价值,在未来全业务运营环境下,本文成果十分重要。
[Abstract]:Telecommunication services and Internet services are converging, and the competitive relationship between them is becoming more and more obvious, and the requirements for Internet and traditional communications cannot be compared with the previous ones. The capability and quality of communication services are more stringent, and the speed of transmission is greatly improved. IP multimedia subsystem (IMSs) is considered to be the main communication technology in the future. Wuxi Unicom fixed-line network users for IMS transformation included in the plan. The paper first introduces the research background, research significance and domestic research situation of the course. Combining with the current situation of fixed network of Wuxi Unicom, based on the transformation of fixed network, this paper summarizes the existing problems, interconnects with existing fixed network, and puts forward the construction scheme of IMS network. The scheme mainly includes the overall structure of IMS, network size prediction, network element setting and disaster recovery mode, and puts forward the IMS network deployment scheme such as routing interworking, network carrying, number address IP allocation, billing and network management, and so on. Wuxi Unicom first reformed the users on the softswitch network with weak service support capability, that is, NGN users. After the gradual transformation of the PSTN network digital relay and ordinary fixed network users. The project was constructed in stages in Wuxi Unicom, and proved to be feasible. At present, Jiangsu Unicom IMS online registered users have reached more than 65000 households. The research results of this paper are beneficial to the future development of fixed voice network, and provide reference value for IMS to provide a unified service platform. In the future, the results of this paper are very important in the whole service operation environment.
