Abstract: A wireless local area network (WLAN) user roaming method, apparatus, and system. A foreign access point (FAP) associated after layer 3 roaming 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.

Abstract translation: 无线局域网（WLAN）用户漫游方法，装置和系统。 在用户的无线终端的层3漫游之后相关联的外部接入点（FAP）接收第一分组; FAP。 用户获取第一漫游隧道的封装条目，其中第一漫游隧道的封装条目中的隧道外部目的地IP地址是无线漫游之前的归属接入点（HAP）的因特网协议（IP）地址 终端，第一个漫游隧道的封装表项中的隧道外部源IP地址为FAP的IP地址。 FAP根据第一个漫游隧道的封装条目封装第一个报文，FAP将封装的第一个报文发送给HAP。 用户在AP之间建立隧道可以大大缩短漫游用户的转发路径。
