Wireless roaming authentication method, wireless roaming method and device thereof

Abstract

The invention discloses a wireless roaming authentication method, a wireless roaming method and a device thereof, and the method comprises the following steps: leading an authentication server to receive a pre-authentication request message sent by a wireless client through a source wireless access device, obtain a network access service identifier which corresponds to a target wireless access device carried in the pre-authentication request message and judge whether pre-authentication is allowed to be carried out on the corresponding target access device to which the wireless client roams or not according to the identifier; and leading the authentication server to obtain authorization information or/and a key of the wireless client if the pre-authentication is judged to be allowed to be carried out on the target wireless access device to which the wireless client roams after receiving the authentication request message sent by the wireless client through the target wireless access device, and respectively send the obtained authorization information or/and the key to the client and the target wireless access device. The adoption of the invention can realize the rapid wireless roaming, improve the universality of the rapid wireless roaming technology and save the cost of system resources.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless roaming authentication method, a wireless roaming method and a device thereof. Background technique [0002] When there are multiple APs (Access Point, AP) in the network environment, and their micro-units overlap each other within a certain range, the client of the wireless user can move in the entire WLAN (Wireless Local Area Networks, wireless local area network) coverage area. The network card can automatically discover the AP with the highest signal strength nearby, and send and receive data through this AP to maintain an uninterrupted network connection. This process is a wireless roaming process. [0003] The WLAN architecture usually includes AP (Access Point, access point), AC (Access Controller, access controller), and Station (that is, a wireless client that conforms to the 802.11 protocol). Among them, the AP provides the bridging function from the...
