4. The method according to claim 3 , wherein the method further comprises:

sending, by the terminal device, first feedback information to the PCF, wherein the first feedback information comprises a result of whether to apply the first authorization information determined by the terminal device.

5. The method according to claim 1 , wherein the first authorization information is carried in a non-access stratum (NAS) message sent by the PCF.

6. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium is configured to store a computer program that causes a computer to perform the method according to claim 1 .

7. A communication method, comprising:

sending, by a policy control function (PCF), authorization information to an access and mobility management function (AMF) or session management function (SMF), wherein a target object of the authorization information is a terminal device, wherein the authorization information is used to indicate whether to authorize the terminal device to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal, wherein the authorization information is determined by the PCF according to authorization assistance information received from a unified data management (UDM);

configuring, by the PCF, a timer for the terminal device, wherein authorization information is valid within a duration of the timer and is invalid when the timer expires;

wherein the authorization information comprises: for a specific network slice, whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal.

8. The method according to claim 7 , wherein the authorization information further comprises at least one of the following:

identification information of the terminal device;

whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal;

for a specific service, whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal;

for a specific group, whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal;

for a specific service in a specific group, whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal;

for a specific external network server, whether the terminal device is authorized to serve as at least one of a relay terminal device and a remote terminal device communicating through a relay terminal; and

public land mobile network (PLMN) information applicable to the authorization information.

9. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium is configured to store a computer program that causes a computer to perform the method according to claim 6 .

10. A terminal device, comprising: a processor and a transceiver connected with the processor, wherein the processor is configured to call and run a computer program from a memory to enable the processor to:
