Abstract: The present disclosure relates to implementing policy control. In one example communication system, a core network exposes a service policy to an application server, and the application server authorizes user equipment with the service policy. Before accessing a service provided by the application server, the user equipment pushes, to the core network, the service policy that needs to be used to access the application server. A core network device performs policy control such as charging, QoS, routing, gating control, or redirection on a service flow or a data packet between the user equipment and the application server according to the service policy pushed by the user equipment.
