Embodiment 1

[0025] figure 1 The implementation process of the method for controlling wireless terminal access provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0026] In step S101, the wireless access point AP receives a probe request frame and an association request frame sent by a wireless terminal.

[0027] In this embodiment, the wireless terminal transmits probe request frames of the 2.4G frequency band and the 5G frequency band to scan the surrounding wireless services, so that the user can selectively associate with the required service set identifier (ServiceSet Identifier, SSID).

[0028] In step S102, it is determined whether the wireless terminal supports a 5G frequency band according to the probe request frame.

[0029] In this embodiment, when the AP receives the probe request frame transmitted by the wireless terminal, it first judges which frequency band the probe request frame comes from. If the probe request frame comes from th...

Embodiment 2

[0046] figure 2 A specific structural block diagram of the wireless access point provided by Embodiment 2 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown. In this embodiment, the wireless access point 2 includes: a request frame receiving unit 21 , a first judging unit 22 , a second judging unit 23 , a first access control unit 24 and a second access control unit 25 .

[0047] Wherein, the request frame receiving unit 21 is used for the wireless access point AP to receive the detection request frame and the first association request frame sent by the wireless terminal;

[0048] The first judging unit 22 is configured to judge whether the wireless terminal supports a 5G frequency band according to the probe request frame;

[0049] The second judging unit 23 is configured to judge whether the first association request frame comes from a 5G frequency band;

[0050] The first access c...

Abstract

The present invention is applicable to the technical field of wireless communication, and provides a method for controlling access of a wireless terminal and a wireless access point. The method includes: the wireless access point AP receives the detection request frame and the first association request frame sent by the wireless terminal; The detection request frame judges whether the wireless terminal supports a 5G frequency band; judges whether the first association request frame comes from a 5G frequency band; if the wireless terminal supports a 5G frequency band and the first association request frame comes from a 5G frequency band, Then allow the wireless terminal to access; if the wireless terminal supports the 5G frequency band, but the first association request frame comes from the 2.4G frequency band, continue to receive the second association request frame sent by the wireless terminal until the The wireless terminal is allowed to access only when the second association frame comes from the 5G frequency band. The present invention enables dual-band wireless terminals to preferentially access the 5G frequency band, improves the utilization rate of the 5G frequency band, and reduces the traffic burden of the 2.4G frequency band.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for controlling wireless terminal access and a wireless access point. Background technique [0002] In large-area wireless local area network (Wireless Local Area Networks, WLAN) deployment, the wireless network in the 2.4G frequency band is the mainstream. The performance of wireless terminals will drop rapidly due to the same-channel interference of other APs. [0003] The emergence of dual-band APs can shunt part of the wireless terminal data that supports the 5G frequency band (referring to the frequency band between 5.1G and 5.8G, including 5.8G), reducing the bandwidth competition and traffic pressure of the 2.4G frequency band. Diversity of terminals, many wireless terminals that support dual frequency will send out 2.4G (referring to the frequency band between 2.405G and 2.485G) and 5G detection request frames when performing wireless ...
