According to one aspect, the subject matter described herein includes a method for communicating service data flow (SDF) event information. The method includes steps occurring at a policy charging and rules function (PCRF) node. The method also includes communicating, via an Rx interface, a request to a deep packet inspection (DPI) node to be notified when an SDF event occurs. The method further includes receiving notification from the DPI node that the SDF event has occurred.
