Embodiment Construction

[0039] like Figure 2-3 A method for realizing access control compatible with the WLAN wireless local area network protocol includes the following steps:

[0040] Step 1: The WLAN wireless local area network includes several wireless terminals, several AP access points and a central server, the wireless terminals are connected to the AP access point through the wireless network, and the AP access point is connected to the central server;

[0041] Step 2: All AP access points store a terminal list for recording wireless terminals allowed to access the network. The terminal list in each AP access point is different, and the central server stores wireless network access Strategy;

[0042] Step 3: Any one of the AP access points AP1 executes two task flows at the same time, that is, the first task flow and the second task flow;

[0043] Step 4: The task to be completed by the first task flow is: the AP access point AP1 regularly sends a unicast Beacon frame to the wireless termina...

Abstract

The invention discloses an access control method compatible with a WLAN wireless local area network protocol and belongs to the technical field of a wireless network. According to the method, terminallists are added to AP access points. The AP access points send Beacon frames to wireless terminals in the terminal lists independently, thereby controlling the determined wireless terminals to be connected with a network. The wireless terminals do not need to be modified and the access selection decision right is handed over from the terminals to the network, thereby realizing wireless network access polices. The method is compatible with an existing commercial standard, various secure polices can be realized, the performance of the wireless local area network is improved, and the network experience of the terminals is optimized.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method for realizing access control compatible with WLAN wireless local area network protocols. Background technique [0002] like figure 1 As shown, in the WLAN wireless local area network defined by the traditional 802.11 standard, effective access control cannot be performed, because the AP access point broadcasts Beacon beacon frames, and each terminal will receive all the AP access points within its effective wireless transmission range. Beacon beacon frame, so as to be able to discover the existence of all AP access points. Then the terminal will select the AP access point with the highest signal strength for the next step of authentication and association. The AP access point can only choose whether to accept or not, but cannot make a decision on access selection, and the decision-making power rests with the terminal. However, terminal access selection is on...
