Abstract: Aiming at the problem that present services are complicated and rigescent in the mobile network,this paper proposes an interaction mechanism based on Network Function Virtualization(NFV) and Software Defined Network(SDN).The system can achieve the complex services’ deployment and dynamic updates of the service chain and matched policy by integrating the information get from the control plane,completing the physical mapping from logic rules to forwarding flows.It meets the demand for Quality of Service(QoS) based on the communication mode of service chain.Experimental result shows that the interaction mechanism proposed can achieve the efficient and rapid deployment of service chain which satisfies the mobile network requirements of flexibility and scalability.

Key words: mobile core network, Software Defined Network(SDN), Network Function Virtualization(NFV), business chain, interaction mechanism
