1. A communication apparatus, which is a first network device or included in the first network device, wherein the communication apparatus comprises a processor, wherein the processor is coupled to a memory; and
the memory, configured to store a computer program, wherein
the processor is configured to execute the computer program stored in the memory, to cause the communication apparatus to perform operations comprising:
sending first information to a second network device, wherein the first information indicates an association relationship between multicast service information and a first terminal device;
receiving second information from the second network device;
generating a configuration message based on the second information, wherein the configuration message indicates an association relationship between the multicast service information and a first logical channel, and the first logical channel is a logical channel of the first terminal device; and
sending the configuration message to the first terminal device, wherein
the first network device has a packet data convergence protocol layer function, a service data adaptation protocol layer function, and a radio resource control layer function, and the second network device has a radio link control layer function, a media access control layer function, and a physical layer function.
