SDN POLICY AND CHARGING CONTROL METHOD AND APPARATUS FOR AN APPLICATION SERVICE CHAIN BASED ON AN SDN NETWORK

摘要

It is an object of the present invention to provide a policy and accounting control method and apparatus for an application service chain based on an SDN network. The PCRF determines an application service chain for the application based on the multidimensional context information corresponding to the application and transmits the corresponding application service chain information to the SDN controller; The SDN controller determines the forwarding rules for the application based on the application service chain information, and forwards the forwarding rules to the corresponding service chaining infrastructure network; The SCEP (s) of the service chaining infrastructure network perform corresponding service functions based on forwarding rules. In contrast to the prior art, the present invention provides a method and system for enhancing existing 3GPP LTE / EPS architecture and policy control, supporting SDN OpenFlow and service chains, and allowing operators to dynamically charge different application flows with different value- It is an unprecedented proposal to change the game rules of LTE policy and billing control method with value added service chain.
