Problems solved by technology

[0004] In related technologies, during the data interaction process based on the IEEE 802.11ba standard, the main communication interface of the site device enters a sleep mode in WUR mode, and the access point device sends a wake-up message frame to the site device to indicate whether the site device needs to wake up the main communication The interface receives buffered data frames or performs time synchronization. However, there is no clear negotiation method on how the site equipment handles the received unicast frames and multicast frames. This also makes the power consumption of the site equipment unable to be further reduced in WUR mode.

Embodiment 1

[0128] Figure 7 A schematic diagram of a communication interaction process of a wireless local area network in accordance with one embodiment of the present invention is shown.

[0129] like Figure 7 As shown, the communication interaction process of the wireless local area network according to an embodiment of the present invention, including: Site Apply 500 In Wur Mode, the secondary communication interface enters periodic sleep mode, and the site device 500 sends a wake-up mode request to the access point device 600. The frame, the access point device 600 divides the plurality of associated site device 500 into different packets based on the sleep cycle, the access point device 600 feeds back the wake-up mode response frame, carrying a multicast address, the site device 500 is received to wake up After the mode response frame enters the sleep state, the secondary communication interface has entered the wake-up state after the dormancy is hibernated. At this time, the access po...

Embodiment 2

[0131] Figure 8 A schematic diagram of a communication interaction process of a wireless local area network in accordance with another embodiment of the present invention is shown.

[0132] like Figure 8 As shown, the site device 500 is in the WUR mode, the secondary communication interface enters the periodic sleep mode, and the site device 500 transmits a wake-up mode request frame to the access point device 600, and the access point device 600 will share multiple associated sites according to the dormant period. The device 500 is divided into different packets, and the access point device 600 feeds back the wake mode response frame, carrying a multicast address, the site device 500 enters the sleep state after receiving the wake-up mode, and the secondary communication interface passes through the sleep time T1 after entering Reviced, at this time, the access point device 600 transmits a wake-up message frame (multicast or broadcast) to the site device 500, and the site device...

Abstract

The present invention provides a wireless local area network communication method, device, access point equipment, and station equipment, wherein the wireless local area network communication method includes: receiving a wake-up message frame, the wake-up message frame contains a destination address information identification bit, and the destination address information When the flag bit is set to the first value, it indicates that the site equipment parses the wake-up message frame, and when the destination address information flag bit is set to the second value, it indicates that the site equipment does not parse the wake-up message frame, wherein the secondary communication interface of the site equipment has entered the WUR mode Under the periodic sleep mode, the main communication interface of the station equipment is always in sleep state. Through the technical scheme of the invention, the power consumption of the site equipment in the WUR mode is further reduced.

Description

Technical field [0001] The present invention relates to the field of communication networking, and in particular, a communication method of a wireless local area network, a communication device of a wireless local area network, a site device, and an access point device. Background technique [0002] In July 2016, IEEE (Institute of Electrical and Electronic Engineers, Electrical and Electronic Engineers Association) 802.11 established the next generation of Wi-Fi (WAKE UP Receiver), ie IEEE (INSTISE OF ELECTRICAL AND ELECTRONICENGINEERS, Electrical and Electronics Engineer Association) 802.11ba, mainly used in the Internet of Things, the purpose is to do the best possible saving equipment. [0003] A Wake UP frame is defined in the IEEE 802.11ba standard, which is the main purpose to wake up the main communication interface of the communication device, that is, the communication device receives the WAKE UP frame through the secondary communication interface, and the power consump...
