Wireless local area network user access fixed broadband network method and system

Abstract

The invention provides a wireless local area network user access fixed broadband network method and system. The method comprises the steps that a broadband gateway BNG device sends an authentication procedure of a wireless local area network WLAN user to an authentication authorization and accounting AAA server, after the authentication which is conducted by the AAA server on the WLAN user is successful, a mobility identity of the WLAN user is acquired by the BNG device from the AAA, and after the BNG device receives the mobility identity of the WLAN user, the WLAN user mobility access is allowed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for a wireless local area network user to access a fixed broadband network. 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. Internet access is one of the most important means [0003] figure 1 It is a schematic topology diagram of a WLAN network in the prior art. Such as figure 1 As shown, a traditional WLAN network includes network elements such as access node AP, access controller AC, and authentication, authorization, and accounting server AAA. After passing AAA authentication, user terminal equipment can access the network through AP and AC, and AC access Point control and configuration protocol CAPWAP is used to manage...

Problems solved by technology

In the current broadband access network, due to the need to prevent problems such as account theft and remote login, the identity information (account, password) of fixed broadband users will be bound with the user's location information during authentication, and the user's location information Add network equipment (such as OLT, DSLAM, Ethernet switch, etc.), and the terminal cannot be counterfeited

Regardless of whether user location information authentication is bound or not, when a fixed broadband user successfully authenticates and accesses, his access location information is also confirmed, and the user cannot continue to access the network when the location moves or the access location information changes.

As a result, in a network environment where fixed broadband users and WLAN users coexist, current BNG devices cannot effectively distinguish between the two types of users, and cannot provide mobility access functions to WLAN users.
