Description
Technical Field
The invention belongs to the technical field of computer communication, and particularly relates to a method, a device, equipment and a storage medium for identifying a wireless terminal.
Background
The WiFi network is a wireless local area network with wide application, and the WiFi network realizes interaction of broadband data by using a wireless communication channel, and the WiFi network at least relates to two types of devices, namely Access Point (AP for short) and wireless terminal (Station). Generally, a WiFi network has an access point and at least one wireless terminal, wherein the access point establishes communication with the wireless terminal over an operating channel. At present, the working channel of the WiFi network is located in a 2.4GHz (2G for short) or 5.8GHz (5G for short), but not all wireless terminals support two frequency bands, that is, the wireless terminals have three types: only supporting 2G or 5G frequency bands (single frequency for short), and simultaneously supporting 2G and 5G frequency bands (dual frequency for short), for a wireless terminal supporting dual frequency, in order to simplify the complexity of the product, the wireless terminal usually only keeps communicating with an access point on one frequency band. In order to improve the communication quality of the wireless terminal, the access point may select a better frequency band for the wireless terminal to communicate according to the load conditions of the 2G and 5G frequency bands, for example, if a wireless terminal supports dual-band, when the access point finds that the load of the 2G frequency band is heavy, the access point may guide the wireless terminal to preferentially operate in the 5G frequency band. Before that, then, the access point needs to first identify whether the wireless terminal supports dual-band.
Before communication, the wireless terminal and the access point need to discover each other, the wireless terminal needs to first send a wireless network query Request (e.g., Probe Request frame specified by IEEE802.11 standard) on all supported channels, and after receiving the wireless network query Request on an operating channel, the access point replies a query Response message (e.g., Probe Response frame specified by IEEE802.11 standard) to the wireless terminal, so that the access point and the wireless terminal complete the device discovery process. For a single-frequency wireless terminal, it only performs device discovery in the 2G or 5G frequency band, but for a dual-frequency wireless terminal, it needs to send wireless network query requests on the 2G and 5G frequency bands, respectively. In the prior art, when an access point receives a wireless network query request sent by the same wireless terminal on both 2G and 5G frequency bands, the wireless terminal is identified as a dual-frequency wireless terminal, and if the access point receives a wireless network query request sent by a wireless terminal only on the 2G or 5G frequency band within a terminal detection time (e.g. 30 seconds), the wireless terminal is identified as a single-frequency wireless terminal.
The 5G frequency band used by the WiFi network includes a plurality of working channels, and these working channels can be divided into two types, the first type is a channel coexisting with radar signals (radar channel for short), and the second type is a channel without radar signals (non-radar channel for short). For a radar channel, in order to ensure that radar signals are not interfered, laws clearly stipulate that WiFi signals must avoid the radar signals, and therefore, in the discovery process of an access point, a wireless terminal firstly sends a wireless network query request on a non-radar channel, and then sends the wireless network query request on the radar channel after detecting radar detection time (for example, 5 minutes) and judging that the channel has no radar signals. When the 5G frequency band of the access point works in a radar channel, because the dual-frequency wireless terminal does not allow to send any message in the radar detection time, if the radar detection time is longer than the terminal detection time, the wireless terminal can not send a wireless network query request in the terminal detection time. Therefore, according to the prior art, when the access point operates on the radar channel of the 5G band, the dual-band wireless terminal is determined as a single-band wireless terminal by the access point, so that the wireless terminal is determined by mistake, and the load of the access point is unbalanced.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
the first embodiment is as follows:
fig. 1 shows an implementation flow of an identification method of a wireless terminal according to a first embodiment of the present invention, and for convenience of description, only the relevant parts related to the embodiment of the present invention are shown, and the following details are described below:
in step S101, the dual-frequency AP device detects a wireless network query request sent by the wireless terminal in the first frequency band, where the dual-frequency AP device supports the first frequency band and the second frequency band.
The embodiment of the invention is suitable for dual-frequency AP equipment, such as a dual-frequency router, a dual-frequency repeater and the like. The 2.4GHz band is a frequency band generally sampled by the early AP device, and since the 2.4GHz band is a free public frequency band, and many electronic products, such as an air conditioner, a microwave oven, a wireless mouse, and bluetooth, use this frequency band, wireless signal interference between devices is easily caused, and therefore more and more AP devices support a dual-frequency function.
In the embodiment of the present invention, the dual-band AP device supports a first frequency band and a second frequency band, preferably, the first frequency band is a frequency band between 2.4GHz and 2.5GHz, and the second frequency band is a frequency band between 5.17GHz and 5.33GHz, or a frequency band between 5.735GHz and 5.835GHz, or a frequency band between 5.49GHz and 5.71GHz, so as to reduce wireless signal interference between devices.
In step S102, when the dual-frequency AP device detects a wireless network query request sent by the wireless terminal in the first frequency band, a current working channel of the second frequency band of the dual-frequency AP device is switched to a non-radar channel, where the current working channel of the second frequency band of the dual-frequency AP device is a radar channel.

Preferably, the second frequency band comprises at least one radar channel and at least one non-radar channel, the non-radar channel is located in a frequency band between 5.17GHz and 5.33GHz or between 5.735GHz and 5.835GHz, and the radar channel is located in a frequency band between 5.49GHz and 5.71GHz, so as to reduce interference of WiFi signals to radar signals in the radar channel.
Illustratively, when WiFi coverage is performed, a current working channel of a dual-frequency AP device 5G frequency band is a radar channel (e.g., channel 52), and if the dual-frequency AP device detects that a radar signal exists in the current working channel, a wireless terminal does not allow to send any message on the current radar channel within radar detection time, so that the current working channel of the dual-frequency AP device 5G frequency band is switched to a non-radar channel, thereby ensuring that the dual-frequency AP device can timely receive a wireless network query request sent by the wireless terminal using a 5GHz frequency band within terminal detection time.
For the radar channel, in order to ensure that the radar signal is not interfered, it is clearly specified by law that the WiFi signal must avoid the radar signal, therefore, preferably, before the wireless terminal accesses the dual-band AP device, the wireless terminal will first send a wireless network query request on all supported channels of the first frequency band and all supported non-radar channels of the second frequency band, thereby ensuring that the dual-band AP device can receive and respond to messages in time on the first frequency band and the second frequency band.
In step S103, the dual-band AP device detects a wireless network query request of the wireless terminal on the working channel after the second frequency band is switched within a preset terminal identification time.
In the embodiment of the present invention, after the dual-frequency AP device switches the working channel on the radar channel to the non-radar channel, the dual-frequency AP device detects the wireless network query request of the wireless terminal on the working channel after the second frequency band is switched within a preset terminal identification time (for example, 30 seconds).
In step S104, when the dual-band AP device detects a wireless network query request of the wireless terminal on the working channel after the second frequency band is switched within the terminal identification time, the wireless terminal is determined as a dual-band terminal.
In the embodiment of the present invention, within the terminal identification time (for example, 30 seconds), when the dual-band AP device detects the wireless network query request of the wireless terminal on the working channel after the second frequency band is switched, it is determined that the wireless terminal has the dual-band network card, and the wireless terminal is determined as a dual-band terminal.
Preferably, after the dual-frequency AP device identifies the wireless terminal, the working channel switched in the second frequency band of the dual-frequency AP device is switched to the radar channel for a preset dwell time, so that the working channel of the dual-frequency AP device is recovered, and channel overlapping is avoided.
In the embodiment of the invention, firstly, the dual-frequency AP equipment detects the wireless network inquiry request sent by the wireless terminal in the first frequency band, the dual-frequency AP equipment supports a first frequency band and a second frequency band, when the dual-frequency AP equipment detects a wireless network inquiry request sent by a wireless terminal in the first frequency band, switching the current working channel of the second frequency band of the dual-frequency AP equipment to a non-radar channel, wherein the current working channel of the second frequency band of the dual-frequency AP equipment is a radar channel, then, the dual-frequency AP equipment detects the wireless network inquiry request of the wireless terminal on the working channel after the second frequency band is switched within the preset terminal identification time, when the dual-frequency AP device detects a wireless network query request of the wireless terminal on the working channel after the second frequency band is switched within the terminal identification time, the wireless terminal is determined as a dual-band terminal, thereby improving the accuracy of identifying the wireless terminal.
