Abstract
An access network device receives first indication information sent by a terminal device, where the first indication information indicates an identifier of a data packet of a multicast service that has been received by the terminal device; the access network device determines a target data packet based on the first indication information; and the access network device sends the target data packet to the terminal device. The terminal device reports the identifier of the received data packet of the multicast service, so that the access network device may determine, based on the identifier, a data packet that is of a multicast service and that has been sent but has not been received by the terminal device.
