随着Internet应用的迅猛发展,IP类多媒体业务正在快速取代语音业务,成为通信网络流量的主要来源。随着“三网融合”的日趋明朗以及业务需求的多样化和差异化,传统电信网络面临的压力越来越大。运营商必须提供越来越多的多媒体业务和数据业务才能吸引住用户,这是传统的PSTN网络所难以提供的。以软交换技术为核心的下一代网络(NGN)具有语音、视频、多媒体融合业务提供能力,以及面向第三方的开放业务能力、扁平的网络结构、设备的部件化、标准化和高集成度等优点,是解决运营商业务发展需求的理想方案。
With the rapid development of Internet applications, IP multimedia services are rapidly replacing voice services and become the main source of communication network traffic. With the increasingly clear understanding of “triple play” and the diversification and differentiation of business needs, traditional telecom networks are under increasing pressure. Operators must provide more and more multimedia services and data services to attract users, which is difficult to provide by the traditional PSTN network. Next-generation networks (NGNs) with softswitch technology at their core provide voice, video and multimedia convergence services as well as third-party open capabilities, flat network architecture, equipment componentization, standardization and high integration , Is to solve the business needs of the ideal business development program.
