Description
Technical Field

Background
In order to meet the requirement of simultaneous Access of wireless terminals with different Numbers of Spatial Streams (NSS), the NSS of each RF unit in the same frequency band supported by an Access Point (AP) is different. The same frequency band here refers to a frequency band to which the radio frequency unit belongs, and is not particularly limited to an operating frequency band of the radio frequency unit. Taking the radio frequency unit 1 with a working frequency band of 5.1 and the radio frequency unit 2 with a working frequency band of 5.2 as examples, the radio frequency unit 1 and the radio frequency unit 2 belong to the same 5G frequency band although the working frequency bands are different.
Before accessing the wireless lan, the wireless terminal first discovers surrounding APs by scanning (active/passive scanning), and after discovering an AP, the wireless terminal usually initiates an association request to a 5G radio frequency supported by the discovered AP and having NSS large. Taking the example that the AP supports dual 5G radio frequency units, wherein one 5G radio frequency unit (denoted as radio frequency unit 3) supports four spatial streams, and the other 5G radio frequency unit (denoted as radio frequency unit 4) supports two spatial streams or one spatial stream, a large number of wireless terminals may be associated with the radio frequency unit 3, resulting in unbalanced load of each radio frequency unit of the same frequency band supported by the same AP.

Detailed Description
The wireless terminal detects the surrounding APs providing wireless services in two ways: active scanning and passive scanning.
The active scanning means that the wireless terminal actively transmits a Probe Request (Probe Request) and receives a Probe Response (Response) returned from the neighboring AP to perceive the AP.
Passive scanning refers to a wireless terminal sensing an AP by listening to a Beacon (Beacon) frame in the air interface.
In the present application, regardless of active scanning or passive scanning, when a wireless terminal senses an AP, the wireless terminal may actively initiate an association request to a radio unit with a large NSS supported by the AP, which may cause a large number of wireless terminals to associate with the radio unit with the large NSS supported by the same AP, and cause unbalanced load of each radio unit with the same frequency band supported by the same AP.
In order to avoid that a large number of wireless terminals are associated with the large NSS radio frequency unit in each radio frequency unit of the same frequency band supported by the same AP, and to achieve access balance of each radio frequency unit supported by the same AP, the present application provides a wireless access method as shown in fig. 1.
Referring to fig. 1, fig. 1 is a flow chart of a method provided by the present application. The method is applied to the AP. As an embodiment, in the present application, an AP may support at least two radio frequency units in the same frequency band, where the same frequency band may be a 5G radio frequency or a non-5G radio frequency, and the present application is not limited in particular.
As shown in fig. 1, the process may include the following steps:
step 101, when the Beacon frame is transmitted by each radio frequency unit supporting the same frequency band in the AP, controlling NSS carried by the Beacon frame transmitted by each radio frequency unit to be the same designated value, so that the wireless terminal accesses the AP according to the received Beacon frame transmitted by one of the radio frequency units.
This step 101 is mainly applied to a scenario in which the wireless terminal passively scans for an AP for providing wireless services. Applied to the scenario, in order to make the wireless terminal not perceive the NSS difference of each radio frequency unit supporting the same frequency band in the AP, the present application performs "spoofing" on the wireless terminal: and controlling NSS carried by Beacon frames sent by all radio frequency units supporting the same frequency band in the AP to be the same designated value. Therefore, when the wireless terminal senses the Beacon frame sent by each radio frequency unit by the AP, the radio frequency is not selected according to the NSS of the corresponding radio frequency unit carried by the Beacon frame, the wireless terminal is prevented from being associated with the radio frequency unit with the NSS which is large and supported by the same AP as much as possible, and the access balance of each radio frequency unit supporting the same frequency band in the same AP is realized.
As an embodiment, in the present application, for a radio frequency unit with a low load, the Probe Response is still replied to the first designated wireless terminal according to the existing manner.
This step 102 is mainly applied to a scenario in which the wireless terminal actively scans for an AP providing a wireless service. In order to prevent unbalanced access of each radio frequency unit supported by the AP, in the present application, the radio frequency unit with a high load among the radio frequency units in the same frequency band supported by the AP is inhibited from replying the Probe Response to the wireless terminal, so that the radio frequency unit with a high load does not reply the Probe Response to the wireless terminal any more, and thus the wireless terminal is guided to associate the radio frequency unit with a low access load, and load balancing of each radio frequency unit in the same frequency band supported by the same AP is achieved.
Thus, the flow shown in fig. 1 is completed.
As can be seen from the process shown in fig. 1, in the present application, the NSS carried by the Beacon frame sent by each radio frequency unit supporting the same frequency band in the AP is controlled to be the same designated value; and inhibiting the radio frequency units with high load in the radio frequency units supporting the same frequency band in the AP from replying the Probe Response to the first appointed wireless terminal, so that the simultaneous association of a large number of wireless terminals to the same radio frequency of the AP can be inhibited as much as possible, and further the load balance of the radio frequency units supporting the same frequency band in the same AP can be realized.
As an embodiment, in this application, after the AP sends a Beacon frame (with NSS being the same specified value) through each radio frequency unit supporting the same frequency band in the AP in step 101, the wireless terminal receives the Beacon frame sent by each radio frequency unit supporting the same frequency band in the AP. After receiving the Beacon frame sent by each radio frequency unit supporting the same frequency band in the AP, the wireless terminal perceives that the Beacon frame sent by each radio frequency unit supporting the same frequency band in the AP is bound with the same wireless service, and finds that the NSS carried by the Beacon frame sent by each radio frequency unit is the same designated value, the wireless terminal does not select the radio frequency unit associated with the access according to the NSS carried by the Beacon frame sent by each radio frequency unit. As an embodiment, the wireless terminal may randomly select one radio frequency unit as the radio frequency unit associated with access; alternatively, the wireless terminal may select the radio unit from which the Beacon frame is received first as the radio unit associated with access, and so on.
After the wireless terminal (here, the second designated wireless terminal is taken as an example) selects the radio frequency unit associated with access, the second designated wireless terminal will send an association request to the selected radio frequency unit. The association request carries the identification of the selected radio frequency unit for association access.
When the AP receives an association request transmitted by the second specified wireless terminal, the flow shown in fig. 2 is executed.
Referring to fig. 2, fig. 2 is a flow chart of association access provided in the present application. As shown in fig. 2, the process may include the following steps:
That is, although the AP "spoofed" the wireless terminal when transmitting the Beacon frame: the NSS carried by Beacon frames sent by all radio frequency units supporting the same frequency band in the AP is controlled to be the same designated value, but once the wireless terminal sends an association request to a certain radio frequency unit, the AP can negotiate association access with the wireless terminal based on the real NSS of the radio frequency unit selected by the wireless terminal to be associated, and the wireless terminal is not deceived.
Specifically, in the present application, a manner of negotiating association access between the AP and the wireless terminal is similar to a manner of association access of an existing wireless terminal, and details are not described here.
Thus, the flow shown in fig. 2 is completed.
It should be noted that, in the flow shown in fig. 1 or fig. 2, as an embodiment, the specified value may be the minimum NSS supported by each radio unit supporting the same frequency band in the AP.
As an embodiment, in the present application, there are many ways to suppress, in step 102, a radio unit with a high load among radio units supporting the same frequency band in the AP from replying the Probe Response to the first designated wireless terminal, and fig. 3 and 4 illustrate two implementation manners, which are described below:
referring to fig. 3, fig. 3 is a flowchart for suppressing a radio frequency unit with a high load from among radio frequency units supporting the same frequency band in the AP from replying the Probe Response to the first designated wireless terminal according to the present application. As shown in fig. 3, the process may include:
As an embodiment, in step 301, selecting the first radio frequency unit with the lowest load from the radio frequency units supporting the same frequency band in the AP may specifically include: and selecting a radio frequency unit with the least number of associated wireless terminals from the radio frequency units supporting the same frequency band in the AP, and taking the selected radio frequency unit as a first radio frequency unit. It should be noted that the first rf unit is named for convenience of description and is not meant to be limiting.

As shown in fig. 4, the process may include:
