A frame transfer method and a related apparatus and a communications system. The method includes: sending, by an access point to a wireless terminal associated with the access point, a group key of a virtual local area network to which the wireless terminal belongs; receiving, by the access point, a frame, where the frame is a broadcast frame of the virtual local area network or a multicast frame of the virtual local area network; encrypting, by the access point, the frame by using the group key of the virtual local area network, to obtain an encrypted frame; and sending, by the access point and in a wireless local area network of the access point, the encrypted frame. The technical solutions of the embodiments of the present invention help reduce complexity of implementing VLAN isolation between wireless terminals in a WLAN and reduce frame forwarding load of an AP. |
