Embodiment Construction

[0042] In view of the above-mentioned problems in the prior art, the embodiment of the present invention provides a WLAN access control scheme that is easy to operate, does not require users to have strong professional knowledge, and meets certain security requirements, thereby avoiding the intrusion of illegal users, Moreover, it has certain versatility and can be applied to various types of WLAN client products (such as PCs, smart phones, e-books, game consoles, etc.).

[0043] Considering that the path loss of the wireless link has a certain correspondence with the distance between the signal receiving and receiving ends, the closer the distance between the signal receiving and receiving ends, the smaller the path loss is, and the farther the signal receiving and receiving ends are, the smaller the path loss is. bigger. The embodiment of the present invention utilizes this feature to perform access control on the terminal to be accessed according to the path loss of the wir...

Abstract

The invention discloses a WLAN access control method and a WLAN access control device. The method comprises the steps that: when WLAN access equipment is in an access judgment state, an indicating terminal reports terminal information; a receiving terminal of the WLAN access equipment receives the terminal information reported according to indication, wherein the terminal information carries the current sending power information of the terminal; the WLAN access equipment determines the wireless link route loss of the terminal according to signal intensity when the terminal information is received and the sending power information in the terminal information; and the WLAN access equipment judges the access of the terminal according to the wireless link route loss and an access judgment threshold, and enters control treatment according to a judgment result. When the method and device are used, the security of WLAN access can be improved and access control operation can be simplified.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless local area network access control method and device thereof. Background technique [0002] With the popularization of WLAN (Wireless Local Area Networks, wireless local area network), wireless routers have gradually changed from original telecom and enterprise equipment to WLAN access devices that can be seen everywhere around users, such as wireless routers, wireless APs (Access Point, entry point), WLAN terminals have also developed from notebooks and PCs to a wide variety of smart phones, e-books, game consoles (PSP), etc., and users have also changed from professional users to ordinary users. [0003] With the popularization of WLAN, ordinary users do not have a very professional understanding and application of WLAN wireless technology. In addition, the sharing mechanism of wireless network provides convenient conditions for illegal users. This will lead t...
