This application discloses a policy control method, including: after a gateway is connected to a network, receiving a first gateway access identifier; selecting a PCRF entity for the gateway accordingly, and establishing a first session for the gateway to implement policy control on the gateway; when a mobile terminal or a fixed-line device is connected to the network through the gateway to perform service data flow access, receiving a second gateway access identifier; if the second gateway access identifier and the first gateway access identifier are the same, selecting, for a service data flow of the mobile terminal or the fixed-line device, a same PCRF entity, and establishing a second session to implement policy control on the service data flow of the mobile terminal or the fixed-line device. The foregoing manner is used to prevent incorrect policy control from causing an exception.
