Abstract
A wireless local area network (WLAN) user roaming method, apparatus, and system. A foreign access point (FAP) associated after layerroaming of a wireless terminal of the user receives a first packet; the FAP. The user obtains an encapsulation entry of a first roaming tunnel, where a tunnel outer destination IP address in the encapsulation entry of the first roaming tunnel is an Internet Protocol (IP) address of a home access point (HAP) before the roaming of the wireless terminal, and a tunnel outer source IP address in the encapsulation entry of the first roaming tunnel is an IP address of the FAP. The FAP encapsulates the first packet according to the encapsulation entry of the first roaming tunnel, and the FAP sends the encapsulated first packet to the HAP. The user establishes a tunnel between the APs can greatly shorten a forwarding path of the roaming tunnel user.
