Problems solved by technology

[0005] In view of this, the main purpose of the present invention is to provide a method and system for WLAN user fixed network access to solve the problem that the WLAN network cannot perceive user subscription information due to the WLAN user passing BNG authentication and thus cannot provide different subscription information based on different users. The Differentiated Services Problem

Embodiment 1

[0078] This embodiment is applicable to scenarios such as figure 2 As shown in the figure, the AC is between the AP and the BNG, and the data packets after the user passes the authentication flow through the AC, and the WLAN device is the AC, as shown in Figure 5 As shown, the process of WLAN user fixed network access includes:

[0079] Step 501, perform the following configurations in the AC: configure the AC as the authentication client, and configure the BNG as the authentication server of the AC.

[0080] Step 502, perform the following configurations in the BNG: configure the BNG as the authentication server, and configure the AC as the authentication client of the BNG.

[0081] Steps 501 and 502 are executed in no particular order.

[0082] Step 503, the user terminal (that is, the WLAN user) sends an EAPoL start (EAPoL-Start) message to the BNG to initiate an authentication request.

[0083] Step 504: After receiving the EAPol-Start message, the BNG sends an EAP-Re...

Embodiment 2

[0100] This embodiment is applicable to scenarios such as image 3 As shown in the figure, the AP and AC are connected through the BRAS. The AC controls the packets of the AP through the BRAS. The packets of the user accessing the network side do not pass through the AC. The WLAN device is the AP. For example, Image 6 As shown, the process of WLAN user fixed network access includes:

[0101] Step 601, perform the following configurations in the AP: configure the AP as the authentication client, and configure the BNG as the authentication server of the AP.

[0102] Step 602, perform the following configurations in the BNG: configure the BNG as the authentication server, and configure the AP as the authentication client of the BNG.

[0103] Steps 601 and 602 are executed in no particular order.

[0104] Step 603, the user terminal obtains an IP address from the BNG through the DHCP protocol.

[0105] Step 604, the user visits the message of the network side and redirects it ...

Embodiment 3

[0115] After a user accesses the network, he changes the user subscription information online by accessing the Portal server, and the process for the AP to obtain the user subscription information is as follows: Figure 7 shown, including:

[0116] Step 701, the user accesses the Portal server, and changes the user's subscription information online (such as changing the user's subscription bandwidth, priority, etc.).

[0117] Step 702, the Portal server sends the changed user subscription information to the AAA server;

[0118] Here, a private protocol message may be used between the Portal server and the AAA server to send user subscription information;

[0119] Step 703, the AAA server sends the changed user subscription information to the BNG through a Radius CoA message or a Diameter CCA message.

[0120] There are two ways for the subsequent BNG to send the changed user subscription information to the AP:

[0121] 1. When the WLAN device is an AC, it is:

[0122] Step...

Abstract

The invention discloses a method for wireless local area network (WLAN) user fixed network access. The method comprises that: after a WLAN user is passed in authentication, a broadband network gateway (BNG) sends the acquired user subscription information to a WLAN device; and after the WLAN device performs related configuration according to the user subscription information, a WLAN user terminal is accessed to the network. The invention also discloses a system for WLAN user fixed network access. A problem that distinguished services based on different subscription information of different users cannot be provided caused by the fact that the WLAN cannot sense the user subscription information due to the fact that the WLAN user is passed in the BNG authentication can be solved.

Description

technical field [0001] The invention relates to the functional field of a data communication network, in particular to a method and a system for WLAN user fixed network access. Background technique [0002] With the rapid development of Internet applications and smart terminals, users need to access the Internet anytime and anywhere through various smart terminals, such as smart phones and tablet computers, for office, communication and entertainment activities. WLAN, Wireless Local Area Networks) access network is one of the most important means. [0003] Such as figure 1 As shown, a traditional WLAN network includes network elements such as access nodes (AP, Access Point), access controllers (AC, Access Controller) and authentication, authorization and accounting (AAA, Authentication, Authorization, Accounting) servers, and user terminal equipment After being authenticated by the AAA server, the network can be accessed through the AP and the AC, and the AC manages and co...
