Communication method, communication device, and communication device of wireless local area network

Abstract

The present invention provides a wireless local area network communication method, a communication device, and a communication device, wherein the wireless local area network communication method for a station that has established an association with a first access point includes: when the station does not receive a message from When the wake-up message frame of the first access point is received, the first message frame from the second access point is received through the secondary communication interface of the station to wake up the main communication interface of the station; a second message frame is generated, The source address of the second message frame is the media access control address of the site and its destination address is the parsed source address of the first message frame; the second message frame is sent through the main communication interface to The second access point is configured to establish an initial network access link with the second access point. This technical solution can effectively prevent the station in the awakened state from being in an aimless state, thereby being able to receive downlink data in time, meeting the requirements of IEEE802.11ba, and making the device more power-saving.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a communication method of a wireless local area network, a communication device and a communication device of a wireless local area network. Background technique [0002] In July 2016, IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.11 established the next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology research group WUR (Wake Up Receiver), namely IEEE802 .11ba, mainly used in the Internet of Things, the purpose is to save the power consumption of the device as much as possible, the most important thing is to make the device that receives the wake-up frame (wake-up message frame) save the power consumption of the device as much as possible. [0003] In WUR (IEEE802.11ba), in order to save more power for the device, its main communication interface is in a power off state, while the ...

Problems solved by technology

[0004] For STAs (Stations, stations) in the above WUR state, because the second communication interface is in the power-on state, that is, the communication state, to receive the wake-up message frame sent by the AP (Access Point, access point), thereby waking up the station equipment The main communication interface of the STAs is used for data communication, and when the AP associated with the STAs is in the power-saving state or away, and the STAs are awakened, the STAs will never be able to wake up for data communication. .11ba needs contradict
