針對當前國內NGN產業正處于從初始的NGN試驗起步階段逐漸進入到NGN實施展開新階段的重要過渡期，基于NGN 新業務的應用需求才是主宰NGN 發展原動力的產業發展原理，對NGN 業務較傳統網絡業務所具有的創新特征以及現有的應用支撐環境在NGN新業務的實際應用中突現出的技術缺陷進行了分析。在此基礎上提出，面向NGN 業務的應
用支撐環境建設需在IP 協議體系、路由功能、組播方式和QoS 等四個方面引入新的技術機制，并就引做了深入討論。

Abstract At present, NGN industry of China is in an important period, transiting from actual
experiment of NGN into implement of NGN. On the basis of the theory that the application
demands for new service of NGN are pushing NGN industry forward ultimately, the innovative
attributes of service of NGN, compared with that of the traditional network, and the
disfigurements of existing application-supported environment in developing service of NGN are analyzed. Grounding on these, this paper points out that new schemes in IP、routing、multicast and QoS should be introduced into the establishment policy of the application-supported environment for services of NGN , which are discussed deeply in the following part .
