21. A method for exercising policy control over an application service flow of an application service, comprising:
sending, by a policy control and charging rules function device, an identifier of the application service and instruction for reporting an event of the application service to a policy and charging enforcement function enabled gateway node the event of the application service comprises starting or stopping of the application service;
receiving, by the policy and charging enforcement function enabled gateway node, the identifier of the application service and the instruction for reporting the starting or the stopping of the application service from the policy control and charging rules function device;
detecting, by the policy and charging enforcement function enabled gateway node according to the identifier of the application service, a data packet of the application service flow;
acquiring, by the policy and charging enforcement function enabled gateway node, information about the starting or the stopping of the application service based on the data packet of the application service flow;
sending, by the policy and charging enforcement function enabled gateway node, notification information which includes the information about the starting or stopping of the application service to the policy control and charging rules function device;
receiving, by the policy control and charging rules function device, the notification information from the policy and charging enforcement function enabled gateway node;
in response to receiving the information about the starting or the stopping of the application service, wherein the information about the starting or the stopping of the application service is not from an application function, but acquired from the policy and charging enforcement function enabled gateway node, generating, by the policy control and charging rules function device, a control policy of the application service flow according to the information about the starting or stopping of the application service included in the notification information sent from the policy and charging enforcement function enabled gateway node, wherein the control policy comprises at least one of a qualify of service (QOS) policy; and
delivering, by the policy control and charging rules function device, the control policy to the policy and charging enforcement function enabled gateway node for exercising policy control over the application service flow transmitted via the policy and charging enforcement function enabled gateway node.
