Abstract: In a communication method, a policy control network element receives first information from a terminal device, where the first information is a banned application identifier, a banned PSI, a URSP identifier, or an allowed application identifier. The policy control network element obtains a first URSP of the terminal device from a data storage network element. The policy control network element determines a second URSP of the terminal device based on the first information and the first URSP. Based on this solution, when deciding a URSP of the terminal device, the policy control network element considers the first information reported by the terminal device, so that a proper URSP can be determined for the terminal device. In addition, this helps avoid signaling overheads caused because the terminal device and a policy control network element side continuously update and maintain a URSP that the terminal device does not need to use.

The SMF enforces a policy for a session of the terminal according to a policy rule in the policy association establishment response. The SMF sends a session establishment response message to the terminal.
