Problems solved by technology

The following issues are prone to occur when WLAN users are roaming: When wireless users move from one access point (AP) to another AP, it may cause re-authentication at the BRAS
[0008] The existing technical solution shields the user's location change information from the BRAS, so that the information of the user's real access point is inaccurate on the RBAS and related authentication servers, and it is impossible to implement differentiated control strategies for different access points

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0037] The main idea of ​​the present invention is to report roaming user information to BRAS equipment through AC, realize update of user terminal information on BRAS authentication equipment and AAA Sever, and avoid re-authentication of WLAN roaming users at BRAS.

[0038] see figure 2 , figure 2 It is a flow chart of the method for preventing re-authentication of roaming users in the present invention. The specific steps are:

[0039] In step 201, the roaming user terminal performs WLAN association and requests access.

[0040] In step 202, the AC detects whether the VLAN of the roaming user terminal changes, and if so, executes step 203, otherwise executes step 209.

[0041] After the AC receives the access request from the ro...

Abstract

The invention provides a method and a device for preventing re-authentication of a roaming user. The method comprises the following steps of: when the virtual local area network (VLAN) of a roaming user terminal is changed, reporting roaming user terminal information to a broadband remote access server (BRAS) through an automatic controller (AC) to realize update of the roaming user terminal information on the BRAS and an authentication, authorization and accounting server (AAA server), and allowing the user to directly access the network by using the internet protocol (IP) of the changed VLAN. Based on the method, the invention also provides the device for preventing re-authentication of the roaming user. Under the condition that the authenticity of the access point of the user terminal is kept, the re-authentication of the roaming user terminal of the changed VLAN is avoided.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for preventing re-authentication of roaming users. Background technique [0002] Wireless Local Area Network (WLAN) technology is one of the hot technologies in the communication field today, especially with the popularization of Wi-Fi terminals, the coverage of WLAN network is getting wider and wider. [0003] The centralized WLAN architecture consists of a wireless controller (AC) and a thin wireless access point (Fit AP). The AC performs centralized control and management of the wireless network, and the Fit AP completes the receiving and sending of wireless packets. AC uses Fit AP as the boundary combined with a fast RF management system, which greatly reduces the association time between wireless clients and APs, and can realize fast switching of wireless adapters such as handheld computers, handheld terminals, and notebook computers in the wireless...
