摘要：An objective of the present invention is to provide a policy and charging control method and apparatus for an application service chain based on an SDN network. PCRF determines an application service chain for an application based on multi-dimensional context information corresponding to the application, and transmits the corresponding application service chain information to an SDN controller; the SDN controller determines a forwarding rule for the application based on the application service chain information, and transmits the forwarding rule to a corresponding service chaining infrastructure network; SCEP(s) in the service chaining infrastructure network perform corresponding service function based on the forwarding rule. Compared with the prior art, the present invention is an unprecedented proposal changing the game rule of LTE policy and charging control method having a value added service chain, which enhances the existing 3GPP LTE/EPS architecture and policy control, supports the SDN OpenFlow and service chain and enables operators to dynamically charge different application flows with different valued added service functions.
