Abstract

In this paper

the up to date research progress of NGN architecture in some international standard organizations were introduced

and some possible evolution roadmap of next generation network was discussed

from softswitch to IMS

is the road of network to convergence.We gave some emphasis to the structure and function entities of the IP multimedia subsystem.
