Problems solved by technology

Take the AP supporting dual 5G radio units as an example, one of the 5G radio units (denoted as radio unit 3) supports four spatial streams, and the other 5G radio unit (denoted as radio unit 4) supports two spatial streams or one spatial stream, then A large number of wireless terminals will be associated with radio frequency unit 3, resulting in unbalanced load of radio frequency units in the same frequency band supported by the same AP

Embodiment Construction

[0019] There are two ways for a wireless terminal to detect surrounding APs that provide wireless services: active scanning and passive scanning.

[0020] The so-called active scanning means that the wireless terminal actively sends a probe request (Probe Request), and perceives the AP by receiving the Probe Response (Response) returned by the surrounding APs.

[0021] The so-called passive scanning means that the wireless terminal senses the AP by listening to a beacon (Beacon) frame in the air interface.

[0022] In this application, regardless of active scanning or passive scanning, when a wireless terminal perceives an AP, it will actively initiate an association request to a radio unit with a large NSS supported by the AP, which will cause a large number of wireless terminals to associate with a radio unit with a large NSS supported by the same AP. As a result, the loads of radio units in the same frequency band supported by the same AP are unbalanced.

[0023] In order ...

Abstract

This application provides a wireless access method and device. In this application, by controlling the NSS carried in the Beacon frame sent by each radio frequency unit supporting the same frequency band in the AP to be the same specified value; Specifying the wireless terminal to reply the Probe Response can suppress as much as possible the simultaneous access of a large number of wireless terminals to the same radio frequency of the AP, thereby achieving load balancing among radio frequency units in the same frequency band supported by the same AP.

Description

technical field [0001] The present application relates to network communication technology, in particular to a wireless access method and device. Background technique [0002] In order to meet the simultaneous access requirements of wireless terminals with different numbers of spatial streams (NSS: Number of Spatial Stream), the NSS of each radio frequency unit in the same frequency band supported by an access point (AP: Access Point) is different. The same frequency band here refers to the frequency band to which the radio frequency unit belongs, and does not specifically refer to the working frequency band of the radio frequency unit. Take radio frequency unit 1 with a working frequency band of 5.1 and radio frequency unit 2 with a working frequency band of 5.2 as an example. Although the working frequency bands of radio frequency unit 1 and radio frequency unit 2 are different, they both belong to the 5G frequency band. [0003] Before accessing the wireless LAN, the wir...
