Terminal roaming method and apparatus, and computer-readable storage medium

A terminal roaming method, applied to a wireless local area network, wherein the method comprises:

• receiving, by a first access point (AP), a first action frame that is sent by a first terminal associated with the first AP and that is used to request to associate with a second AP, wherein a receiver address of the first action frame is an address of the first AP, and the first action frame further comprises an identifier of the second AP;
• sending, by the first AP, a first association request message obtained based on the first action frame, wherein the first association request message comprises an identifier of the first terminal;
• and
• sending, by the first AP, a response frame for the first action frame to the first terminal based on a result returned by the second AP for the first association request message, wherein the response frame comprises an association identifier allocated by the second AP to the terminal and the response frame is used to indicate whether an association succeeds;
• receiving, by the first AP, a second association request message sent by a third AP, wherein the second association request message comprises an identifier of a second terminal associated with the third AP, and the second association request message is obtained based on a second action frame that is sent by the second terminal to the third AP and that is used to request to associate with the first AP;
• sending, by the first AP, refresh indication information to an upper-layer access device, wherein the refresh indication information comprises the identifier of the second terminal, and the refresh indication information is used to indicate to the upper-layer access device to send downlink data corresponding to the second terminal to the first AP;
• and
• when the first AP receives the downlink data that is sent by the upper-layer access device and that corresponds to the second terminal, caching, by the first AP, the downlink data corresponding to the second terminal.
