Abstract: A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. Flow identifier information may be generated for a signaling IP flow and a media IP flow, to unify a mechanism for reporting a signaling path status and a mechanism for reporting a bearer event of a media IP flow. In the method, the mechanism for reporting a signaling path status is not limited by the parameter of Flow Usage.

Abstract: A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.
