技术的进步、业务的拓展、用户需求的不断提升、网络容量的日益扩张等等,种种迹象都表明现有网络已经逐渐显现出难以满足通信产业发展的趋势。在新的发展形势下,运营商、制造商、技术提供商以及政府机构等各方都开始了对构建新的网络的探索。被认为是具备了多业务、宽带化、分组化、开放性、移动性、兼容性、安全性、可管理性等基本特征的NGN应运而生,业界希望能够借助NGN重振电信业辉煌。尤其在最近一段时间以来,围绕NGN发展现状、技术趋势、业务应用和市场前景等内容,业界的探讨与关注日益升温。对于中国乃至全球电信业而言,NGN的发展方向、研究重点、核心技术、业务拓展以及商业模式等无疑成为我们需要关注的热点话题。正是基于对NGN战略性的充分认识,本期“新电信沙龙”特邀中国电信集团副总裁韦乐平、信息产业部电信研究院总工程师蒋林涛、UT斯达康(中国)有限公司主任结构师/首席科学家杨景、北京西门子通信网络有限公司(SCNB)NGN业务管理部高级总监张健等专家和厂商代表,分别从不同角度就NGN的发展展开深入分析和探讨。
Technological advances, business expansion, rising user demand, increasing network capacity and so on, all the signs show that the existing network has gradually emerged difficult to meet the development trend of the communications industry. In the new development situation, operators, manufacturers, technology providers and government agencies and other parties have started to explore the construction of a new network. It is considered as an NGN that possesses such basic features as multi-service, broadband, grouping, openness, mobility, compatibility, security and manageability. The industry hopes to revitalize the telecommunications industry with NGN. Especially in the recent period, the discussion and concern of the industry are heating up around the status quo of NGN development, technology trends, business applications and market prospects. For the telecom industry in China and even the world, the development direction, research focus, core technology, business development and business model of NGN will undoubtedly become the hot topics that we need to pay attention to. It is based on a full understanding of the strategic importance of NGN. In the current issue, “New Telecom Salon” invited Wei Leping, vice president of China Telecom Group, Jiang Lintao, chief engineer of Telecommunications Research Institute of Ministry of Information Industry, UT Starcom (China) Co., Ltd. Yang Jing, chief architect / chief scientist, and Zhang Jian, senior director of NGN Business Management Department of Beijing Siemens Networks Co., Ltd. (SCNB), and representatives from manufacturers made in-depth analysis and discussion on the development of NGN from different perspectives.
