Abstract: A multicast service processing method and an access point are disclosed. The method includes: generating, by an access point (AP), a first group addressed frame and an individually addressed frame based on a multicast packet, where the first group addressed frame is encrypted by a first multicast key, and the individually addressed frame is encrypted by a unicast key of a second terminal.

Abstract: A method for setting a packet transmission mode and a device are provided, and relate to the communications field. To optimize sending of a multicast packet, both robustness and resource consumption are considered. A specific solution is as follows: when a packet amount in a packet cache queue exceeds a first threshold, changing a state of a first multicast group to multicast transmission, where a state that is of the first multicast group and that is before the change is multicast-to-unicast transmission. Technical solutions of this disclosure are used for setting a packet transmission mode.
