网络融合的趋势分析和展望

下一代网络业务、控制、承载、接入分离的思想为未来网络融合提供了统一的架构。网络融合包括业务融合、核心网络融合、接入网络融合、终端融合、运维融合等多个方面。未来融合网络的发展趋势将是在核心控制层采用IP多媒体子系统(IMS),在核心承载层采用因特网协议/多协议标记交换(IP/MPLS)技术,在业务层采用统一开放的业务提供架构,在接入层支持固定、移动、窄带、宽带等多种接入技术,终端则呈现多模化和智能化的趋势,最终实现一个用户、一个号码、一个终端、一个账单、一个核心网络、随时随地享受的全业务模式。

Trends and Prospects of Network Convergence

NGN, characterized by the separation of services from control and transport, creates a framework for the future network convergence. Network convergence encompasses service convergence, core network convergence, access network convergence, terminal convergence and centralized network operation and management. The next generation converged network will use IP Multimedia Subsystem (IMS) as core control; use Internet Protocol/Multiprotocol Label Switching (IP/MPLS) as the transport vehicle for the core bearer layer; creates an open service environment at the application layer; integrates disparate access technologies at the access layer. The handset development, meanwhile, will be centered on intelligent and multimode operations, and eventually achieve the goal of "many services on one terminal" meaning that users will have just one device / bill / number / core network.
