摘      要：The concept of the separation of service,control,bearer and access in the Next Generation Network (NGN) provides a unified architecture for the network convergence in the future. Network convergence involves service,core network,access network,terminal,and operation and maintenance convergence. In the future,the converged network’s trend is to use IP Multimedia Subsystem (IMS) at the core control layer; Internet Protocol/Multiple Protocol Label Switching (IP/MPLS) technology at the core bearer layer; unified and open service provisioning architecture at the service layer; as well as support fixed,mobile,narrowband and broadband access technologies and so on at the access layer. Terminals will evolve to be multi-modular and intelligent,and would finally enable users to access full services anytime and anywhere using one number,one terminal,one account and one core network.
