The present invention discloses an authentication method in WLAN. When an AAA server, which received an authentication request from a WLAN user terminal, sends a user information request to the home user information server, the method comprises the following steps: after receiving the user information request, the home user information server decides whether there is an AAA server registered to serve the WLAN user terminal, if not exist, returns the user data of the WLAN user terminal to the AAA server and ends the current procedure; if exist, the home user information server selects one AAA server to authenticate the WLAN user terminal and initiating a process of deleting the relevant information and connections of the WLAN user from other AAA servers associated with the WLAN user. This invention prevents one WLAN user terminal from being authenticated by more than one AAA server, thus avoiding scattered users' data. Moreover, it presents a simple, convenient, and flexible authentication method in WLAN. |
