7. The method of claim 6 , wherein

the executing the access control operation corresponding to the MBMS service according to the access control configuration parameters comprises:

generating a first random number;

generating a second random number if access is determined to be prohibited based on the first random number and the second information; and

activating a first timer based on the second random number and the third information, the first timer being configured to restrict access to the MBMS service.

8. The method of claim 1 , wherein

the access control configuration parameters comprise a first access control configuration parameter of having a correspondence with attribute information of the MBMS service, the attribute information comprises at least one of the following:

an access category corresponding to the MBMS service, a service identity corresponding to the MBMS service, identity information of a member corresponding to the MBMS service, or identification information of a member corresponding to the MBMS service.

9. A terminal device comprising:

a processor and a memory for storing a computer program, the processor for calling and executing the computer program stored in the memory to perform a method, the method comprising:

a terminal device receiving first configuration information, wherein the first configuration information comprises access control configuration parameters corresponding to a first access category; and

the terminal device executing an access control operation corresponding to a multimedia broadcast multicast (MBMS) service according to the access control configuration parameters;

wherein

the access control configuration parameters comprise first indication information, and the first indication information is configured to indicate at least one of the following:

the MBMS service that executes or requires to execute the access control operation; or

the MBMS service that does not execute or is not required to execute the access control operation;

wherein

the first indication information comprises a first bitmap, each bit in the first bitmap corresponding to an MBMS service, each bit having a value for indicating whether the MBMS service corresponding to the bit executes or requires to execute the access control operation.

10. An access control method, the method comprising

a network device sending first configuration information, wherein the first configuration information comprises access control configuration parameters corresponding to a first access category; the access control configuration parameters being used by the terminal device to execute an access control operation corresponding to an MBMS service;

wherein

the access control configuration parameters comprise first indication information, and the first indication information is configured to indicate at least one of the following:

the MBMS service that executes or requires to execute the access control operation; or

the MBMS service that does not execute or is not required to execute the access control operation;

wherein

the first indication information comprises a first bitmap, each bit in the first bitmap corresponding to an MBMS service, each bit having a value for indicating whether the MBMS service corresponding to the bit executes or requires to execute the access control operation.

11. The method of claim 10 , wherein

the access control configuration parameters comprise at least one of the following:

first information, wherein the first information is configured to determine an access identity that allows access and/or an access identity that prohibits access;
