Authentication method and system for access to wireless network

Abstract

The invention discloses an authentication method for accessing wireless networks, which is applied to realizing that a terminal for controlling access can only be used in a certain control area in a wireless network. The authentication method comprises the steps that: an authentication server receives the authentication message of access request containing the media access control (MAC) address of a request access terminal and the MAC address of a wireless access point which is connected with the request access terminal from a wireless controller, acquires the MAC address of an authentication terminal according to the MAC address of the wireless access point, determines that when the MAC address of the authentication terminal contains the MAC address of the request access terminal, the received message of authentication is returned to the wireless controller. The invention discloses an authentication system for accessing wireless networks and an authentication server.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to an authentication method and system for accessing wireless networks. Background technique [0002] At present, telecom operators have paid more and more attention to and are constantly promoting the construction and operation of wireless local area networks. Different from WLAN (Wireless Local Area Network) built and operated by homes, businesses, or communities in the past, carrier-class WLAN requires more thoughtful network planning and more professional network construction. Introduce a secure authentication system to verify the legitimacy of terminal equipment accessing the network and determine whether it is a legitimate user registered with a telecom operator. [0003] At present, the more commonly used authentication methods for accessing wireless networks include: the authentication method in which the authentication platform pops up an account and password ent...

However, the authentication method of entering the account password can only be used for relatively intelligent terminals, and multiple terminals can use a legal account password to access the WLAN, so it cannot be specific to the terminal during access control.

Moreover, when using all the current authentication methods, it is easy to cause wireless network congestion when a large number of users access the wireless network in a certain geographical area, for example: in a campus WLAN, in the same teaching building, if teachers and students All terminals must be connected to the wireless network, which causes congestion of the wireless network due to the large number of users; similarly, in the WLAN of the Olympic venues, if a large number of media terminals are connected to individual venues at the same time, this may cause the network to fail to operate safely and stably
