Problems solved by technology

In other words, the fact that the working channel of the main transceiver is busy does not mean that the station cannot send wake-up frames at this time
In the prior art, the channel on which the wake-up receiver works has not been regulated

Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0035]The embodiment of the present invention can be applied to a Wireless Local Area Network (WLAN), and currently WLAN adopts IEEE (English: Institute of Electrical and Electronics Engineers, Chinese: Institute of Electrical and Electronics Engineers) 802.11 series. A WLAN can include multiple Basic Service Sets (BSS). The network nodes in the BSS are stations, and the stations include access point stations (AccessPoint, AP) and non-access point stations (English: None Access Point Station, referred to as: Non-AP STA), each basic service set can include one AP and multiple Non-AP STAs associated with the AP. The stations of the entry category, and the APs in the embodiments of the present invention refer to stations of the access category.

[0036] Access point stations are also called wireless access poin...

Abstract

The embodiment of the present invention discloses a station association method and device. The station association method includes: receiving a message sent by at least one access point AP, the message carries a wake-up radio load information element, and the wake-up radio load information element includes The load information of the wake-up radio channel managed by the AP; according to the load information, select a target AP from the at least one AP for association. By adopting the embodiment of the present invention, the STA can be notified of the load information of the wake-up radio channel managed by the AP, so that the STA can select a suitable AP for association.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a station association method and device. Background technique [0002] In a Wireless Fidelity (WiFi) network, a considerable part of the energy of the device is wasted in idle listening when there is no received signal. The current traditional 802.11 protocol (802.11b / a / g / n / ac, etc.) The solution focuses on optimizing the device sleep strategy. In addition to optimizing the sleep strategy, another technical approach to reduce energy waste in idle listening of devices is to use a low power wake up receiver (Low Power Wake Up Receiver, LP-WUR) (herein referred to as WUR). The idea is that in addition to the traditional 802.11 transceiver (802.11mainradio, 802.11 main transceiver module, and WiFi main transceiver module), the receiver device (such as STA) adds a low-power wake-up receiver (WUR) part, such as figure 1 As shown, when the 802.11 main transceiver mod...
