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 invention provides an access authentication method and device for connecting a specified AP (Access Point). The method comprises the following steps: initiating authentication to an authentication server according to a first request message of terminal equipment sent on the AP by an AC (Access Controller); judging whether or not the AP is an accessible AP of the terminal equipment; if so, issuing an access permission command to the AP in order that the AP transmits a hidden SSID (Service Set Identifier) to the terminal equipment; when the terminal equipment connects the AP through the hidden SSID request, receiving the MAC (Media Access Control) address of the terminal equipment transmitted by the AP and the MAC address of the AP; transmitting the MAC address of the terminal equipment and the MAC address of the AP to the authentication server; and when an authentication pass command returned by the authentication server is received, issuing the access permission command to the AP in order that the AP is connected with the terminal equipment. Thus, control terminal equipment accesses the specified AP, and the problem of projection chaos is solved.

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 schoolbag is one of the typical campus WiFi (Wireless-Fidelity, wireless fidelity) applications. Its basic principle is that students use terminal devices such as tablet computers to connect to the AP (Wireless Access Point, wireless access point) ), 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 classroom is uniform Therefore, under...
