Embodiment approach

[0065] The first preferred implementation manner: after the WLAN device receives the user's IP address request, assigning the IP address to the user includes: after the WLAN device receives the user's IP address request, assigning the above-mentioned IP address to the above-mentioned user in the local address pool; Alternatively, after receiving the user's IP address request, the WLAN device assigns the above IP address to the above user through the Dynamic Host Configuration Protocol (DHCP) server.

[0066] The second preferred implementation manner: after the WLAN device receives the user's IP address request, assigning the IP address to the user also includes: after the WLAN device receives the user's IP address request, assigning the above-mentioned AAA server to the above-mentioned user through the above-mentioned authorization information IP addresses are assigned to the above users.

[0067] The third preferred implementation manner: after the WLAN device receives the u...

Embodiment 1

[0088] This embodiment introduces a method for processing data packets in a scenario where the AC is directly connected. The AC is located between the AP and the BNG. The AC serves as the 802.1x authenticator for the user and assigns an IP address to the user. Figure 8 It is a flowchart of a method for processing data packets in an AC direct connection scenario according to Embodiment 1 of the present invention, as shown in Figure 8 As shown, the method includes the following steps (step S802-step S826):

[0089] In step S802, the user terminal starts an authentication request by sending EAPoL-Start.

[0090] In step S804, the AC sends an EAP-Request / Identity message to the user terminal after receiving the EAPoL-Start message, requesting the user terminal to send the user name to the BRAS.

[0091] Step S806, the user terminal sends an EAP-Response / Identity message to the AC, including the user name.

[0092] Step S808, the AC encapsulates the EAP-Response / Identity messag...

Embodiment 2

[0109] This embodiment introduces the processing method of data packets in the AC direct connection scenario. The AC is located between the AP and the BNG. The AC acts as the user's 802.1x authenticator. The text performs network address translation. Figure 10 It is a flowchart of a method for processing data packets in an AC direct connection scenario according to Embodiment 2 of the present invention, as shown in Figure 10 As shown, the method includes the following steps (step S1002-step S1026):

[0110] Step S1002 to step S1016 are user identity authentication processes, and the specific process is similar to step S802 to step S816 in the above embodiment, and will not be repeated here.

[0111] Step S1018, the user sends a DHCP Discover message to the AC to request an IP address, and the AC allocates a private network IP address to the user and sends it to the user, and at the same time, the AC allocates a public network IP address and a port number segment for network...

Abstract

The invention discloses a data message management method, a data message management device and a data message management system. The data message management method includes the followings steps that: a broadband network gateway (BNG) device performs user identity authentication through an authentication, authorization and accounting (AAA) server, and stores authorization information and identification information of an authenticated user after the user identity authentication succeeds; the broadband network gateway (BNG) device receives an accounting initiation request which is transmitted by a wireless local area network (WLAN) device; the broadband network gateway (BNG) device matches identification information carried in the accounting initiation request with the identification information of the authenticated user, and determines authorization information according to the identification information of the authenticated user after the matching succeeds; and the broadband network gateway (BNG) device identifies data massages of the user according to the identification information of the user, and manages the data massages according to the authorization information of the user. With the data message management method, device and system of the invention adopted, the problem of incapability of the broadband network gateway (BNG) device to identify users in a situation in which the broadband network gateway (BNG) device does not participate in a user address allocation process, can be solved, and therefore, the broadband network gateway (BNG) device can be rapidly deployed so as to realize user service and flow management and improve the service quality of a wireless local area network (WLAN) under the condition that a current network architecture of wireless local area network (WLAN) user authentication and address allocation is not modified.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data message management method, device and system. 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. (Wireless Local Area Networks, WLAN for short) access network is one of the most important means. [0003] figure 1 is a schematic topology diagram of a traditional WLAN network according to related technologies, figure 2 is a schematic topology diagram of another traditional WLAN network according to related technologies, such as figure 1 and figure 2 As shown, a traditional WLAN network includes an Access Point (AP for short), an Access Controller (AC for short), an Authentication, Authorization, and Accounting server (AAA for short)...
