This paper analyzes the current situation and problems of operators’ communication network architecture

and expounds the four key technologies that affect the future communication network architecture: SDN

NFV

cloud and 5 G technology. According to the four technical architecture design

the general description of the future network target architecture blueprint

and put forward fi ve major changes in the future network architecture transformation

namely network soft decoupling

network function to control separation

network cloud

fl at architecture

hierarchical layout.
