Abstract: A terminal roaming method, an apparatus, and a wireless local area network are disclosed, and belong to the field of WLAN technologies. A session parameter used when a terminal performs data exchange with an original associated AP is migrated to a roaming target AP. After the terminal is associated with the roaming target AP, the roaming target AP can continue data exchange with the terminal based on the migrated session parameter, and the terminal can also continue data exchange with the roaming target AP based on the session parameter used when the terminal performs data exchange with the original associated AP. The terminal and the roaming target AP do not need to perform session negotiation again, to shorten a data service recovery time required after a roaming handover of the terminal, and reduce a service transmission delay. This improves smoothness of roaming handover of the terminal.
