Embodiment Construction

[0058] See figure 1 , is a network architecture diagram of electronic teaching in an exemplary embodiment of the present invention, wherein AC is responsible for controlling the wireless access authentication process of classroom 1 and classroom 2; the authentication server and portal (entry) server assist AC (Access Controller, access controller) for access authentication. An AP is deployed in each classroom, as well as the video mirroring transmission device and projection screen bound to the AP. The AP is used to transmit WiFi signals and perform access authentication on the terminal device when receiving an access request sent by the terminal device. After the authentication is successful, the terminal device can project multimedia files to the projection screen through the video mirroring transmission device to realize e-learning. The switch between AC and AP1 and AP2 is used to send the authentication packets sent by AP1 and AP2 to AC, and forward the commands issued b...

Abstract

The present invention provides an access authentication method and device for connecting to a designated AP. The method includes: the AC initiates authentication to the authentication server according to the first request message of the terminal equipment sent by the AP; The accessible AP of the terminal device; if so, issue an access permission command to the AP so that the AP sends the hidden SSID to the terminal device; when the terminal device requests to connect to the AP through the hidden SSID , receiving the MAC address of the terminal device and the MAC address of the AP sent by the AP; sending the MAC address of the terminal device and the MAC address of the AP to the authentication server; when receiving the authentication When the authentication instruction returned by the server passes, an access permission instruction is issued to the AP, so that the AP is connected to the terminal device. Therefore, the purpose of controlling the access of the terminal device to the specified AP can be achieved, thereby avoiding the problem of projection confusion.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an access authentication method and device for connecting to a designated AP. Background technique [0002] The electronic school bag is one of the typical campus WiFi (Wireless-Fidelity, wireless fidelity) applications. Its basic principle is that students use tablet computers and other terminal devices to connect to the AP (Wireless Access Point, wireless access point) of their classrooms through WiFi. , and then project the multimedia content in the terminal device to the display device in the classroom through the multimedia device bound to the AP, thereby realizing electronic teaching. [0003] However, during the application process, since the terminal device usually automatically selects the access AP according to the signal strength, the school usually adopts a unified SSID (Service Set Identifier, service set identifier) ​​deployment, that is, the AP deployed in each cl...
