1.引言 智能网(IN)是目前各国通信公司致力发展的热点技术之一。在过去的两年里,全球的IN技术和业务得到了异常迅速的发展。推动IN发展的因素主要有:一,电信市场的竞争日益激烈,网络运营者需要更快地推出新业务和性能,减少提供新业务对交换机生产厂家的依赖,更加经济有效地利用对网络的投资;二,技术的发展,特别是计算机技术在通信中的应用使IN的结构得以实现。IN系统在很大程度上建立在标准计算机平台上,许多运营公司已经开始寻找基于行业标准的UNIX系统用于IN业务的生成。
1. INTRODUCTION Intelligent Network (IN) is one of the hot technologies that various national communication companies are devoted to developing at present. In the past two years, the global IN technology and business have been extremely rapid development. The main factors driving the development of IN are: First, the competition in the telecom market is getting fiercer. Network operators need to introduce new services and performance more quickly, reduce the dependence on switching manufacturers to provide new services, and make more economical and effective use of network investments ; Second, the development of technology, especially the application of computer technology in communication, made IN’s structure possible. The IN system is largely based on a standard computer platform and many operating companies are already looking for industry-standard UNIX systems for IN business generation.
