摘要
本文针对当前固定交换网络的的现状,阐述了固网核心网演进的方式,分析比较了软交换和IMS的异同,讨论了基于IMS的网络演进路径,介绍了基于IMS的固定与移动网络融合方案。同时对由于核心网络发展所引起的对周边系统的影响也做了简要的阐述。最后文章探讨了网络融合的发展思路,并从业务、网络、运维等方面分析了融合策略。
This paper discueesd the way of fixed core network evolution in connection with present situation. Analysis and comparison of the softswitch and IMS and the IMS-based network evolution path was discussed. IMS-based fixed and mobile network convergence program was introduced. The affect to the other system was discussed due to the core network. Finally, we discussed the integration strategy of business, network, operation and maintenance.
