Abstract
A method and a system for exercising policy control, a policy and charging enforcement function (PCEF), and a policy control and charging rules function (PCRF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). The method includes of the following steps: a PCRF receiving information about an application event sent by a PCEF; and the PCRF generating a control policy for a service flow of the application according to the information about the application event, and delivering the control policy to the PCEF. 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, so as to exercise an effective policy control over the QoS guarantee, charging and gating of the service flow, thus meeting the requirements of exercising the policy control over data applications with no AF being involved.
