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.
Abstract translation: 提供了一种执行策略控制，策略和计费执行功能（PCEF）的方法和系统，可以解决没有应用功能（AF）的应用服务流不能执行策略控制的问题。 在该方法中，PCRF在从PCEF订阅应用事件之后，接收由PCEF发送的应用事件的信息; 并且PCRF根据关于应用事件的信息为应用的服务流生成控制策略。 在本发明中，PCEF将获取的关于应用事件的信息发送给PCRF，使得即使不涉及AF，PCRF仍然可以根据包括关于应用事件等的信息的策略上下文来生成控制策略 。
