NGN是以软交换为核心的/分层的、业务驱动的电信级可运营的网络;软交换技术是基于业务控制与呼叫控制分离、呼叫控制与承载分离思想,以软件功能来实现硬件交换的技术;两者的结合无疑是符合电信发展趋势的。本文第二章对NGN和软交换技术作以概要介绍。 本文对软交换网络的组网运营模式从NGN的四个层次进行了研究,给出了可行的建议方案,尤其是其中对于传送网层次的研究和私网NAT/防火墙穿透的研究具有较高价值。这是第三章的研究内容,也是论文的一个研究重点。本文第四章探讨了在软交换网络中的业务提供问题,围绕其业务提供的功能实体,研究了怎样利用其开放的网络特性提供业务,并给出了几种新业务实现实例。 在最后对整个辽宁地区的软交换体系实现方案做了具体的分析,给出了几种实现方案,并对这几种方案从优势和劣势进行了比较,并给出最佳的实现方案。
In recent years, the concept and architecture of traditional telecom has been greatly changed by the Net-volution such as the developing Internet. With the rapid development of Internet and Network, the flux of the world’s service traffic data has grown rapidly. In some countries and areas, the service traffic data has exceeded that of voice, and has become the mainstream of telecom traffic. Because of the high bandwidth utilization and exoteric protocols, also available comprehensive service including voice, data and multi-media, it goes without saying that the next generation network will evolve toward packet network. But traditional PSTN is still the important revenue source for telecom carrier. Moreover, PSTN has reached every points of society; it has stable services and users. Network evolution and convergence must be done on the basis of current network. We cannot re-construct a brand-new network despite of what we have now. What telecom carrier eagerly wants to do is how to propel the PSTN to evolve toward network based on packet network without high cost, in other words, how to merge PSTN with the data communication network. At this time, soft switch-based NGN came to being. It is key component, which can transfer the telecommunication network by the traditional electric circuit-switching scheme to the packet network. And it is also the key component of packet switch network. This article has mainly (Dominate layer、transport layer、access layer、application layer) conducted the research to the soft-switch network from four layers, as well as the research of the service
