Abstract

The invention discloses a boundary control method and system, and an access controller, and belongs to the technical field of networks. The method comprises: obtaining position information of a terminal, the position information being used for determining the position of the terminal; according to the position information, detecting whether the terminal is within a preset scope, the preset scope being a scope in which the terminal is allowed to access to a network; and if it is detected that the terminal is not within the preset scope, rejecting the terminal' access to the network. According to the invention, through obtaining the position information of the terminal, whether the terminal is within the preset scope in which the terminal is allowed to access to the network is detected according to the position information of the terminal, and if it is detected that the terminal is not within the preset scope, the terminal' access to the network is rejected, such that the problem of illegal access to the network after an illegal user beyond the preset scope obtains a network password is solved, and the effect of protecting the network from being illegally accessed by the user beyond the preset scope.

Description

technical field

[0001] The invention relates to the field of network technology, in particular to a border control method, an access controller and a system. Background technique

[0002] Wi-Fi (wireless fidelity, wireless fidelity) is a wireless broadband technology. Through Wi-Fi, the wireless interconnection of terminals such as personal computers and various handheld devices can be realized.

[0003] Wi-Fi achieves wireless signal coverage through AP (access point, access point). AP has a certain coverage range, and terminals within this range can realize wireless interconnection. Considering security issues, existing technologies generally use encryption technologies such as WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access, Wi-Fi network security access) to encrypt the network to ensure network security. safety.

[0004] In the process of realizing the present invention, the inventor found that the existing technology has at least the following disadvant...
