Description
Technical Field
The present invention relates to the field of communication network technologies, and in particular, to a communication method of a wireless local area network, a communication apparatus of a wireless local area network, an access point device, and a station device.
Background
In 2016, the IEEE (Institute of Electrical and Electronic Engineers) 802.11 established the next-generation wur (wake up receiver) group of Wi-Fi (Wireless Fidelity) technologies, namely the IEEE (Institute of Electrical and Electronic Engineers) 802.11ba, which is mainly applied to the internet of things and aims to save the power consumption of the equipment as much as possible.
A wake-up message (wake-up) frame is defined in the IEEE 802.11ba standard, and the main purpose of the wake-up message frame is to wake up a primary communication interface of a communication device, that is, the communication device receives the wake-up frame through a secondary communication interface, and the power consumption required by the wake-up message frame is not more than 1mw, so that the standby power consumption of the secondary communication interface is far lower than that of the primary communication interface, which is beneficial for the communication device to save power consumption.
In the related art, in order to reduce power consumption for transmitting and receiving a wake up frame, the length of the wake up frame needs to be reduced, and therefore, it is defined that address information carried by the wake up frame is not a MAC (Media Access Control, Media Access Control sublayer protocol) address, and in order to reduce occurrence of data collision, it is still necessary for the Access point device and the station device to negotiate an address field of the wake up frame, but how to negotiate and determine a receiving address and a transmitting address of the wake up frame is not clearly defined.

To this end, an object of the present invention is to provide a communication method of a wireless local area network.
Another object of the present invention is to provide a communication apparatus for a wireless local area network.
It is still another object of the present invention to provide an access point device.
It is yet another object of the present invention to provide a station apparatus.
In order to achieve the above object, a technical solution of a first aspect of the present invention provides a new communication method for a wireless local area network, including: generating a response message frame, wherein the response message frame carries a preset Hash digest algorithm; and sending a response message frame to the station equipment on the main communication channel to instruct the station equipment to determine a part of basic service set identifications corresponding to the basic service set identifications according to a preset hash digest algorithm and/or determine a part of associated identifications corresponding to the associated identifications according to the preset hash digest algorithm, wherein the part of basic service set identifications are used for indicating sending addresses of the wake-up message frame, the part of connection identifications are used for indicating receiving addresses of the wake-up message frame, the length of the sending addresses of the response message frame is greater than that of the sending addresses of the wake-up message frame, and the length of the receiving addresses of the response message frame is greater than that of the receiving addresses of the wake-up message frame.
In the technical scheme, a response message frame is generated, and the response message frame carries a hash (hash) digest algorithm, so that the station equipment calculates and determines part of Basic Service Set identifiers (PBSS ID) according to the hash digest algorithm and the Basic Service Set identifiers (BSS ID) and/or calculates part of associated identifiers (PAID, Partial association identifiers) according to a preset hash digest algorithm and the Associated Identifiers (AID), and further carries the PAID and PBSS IDs with fewer bits when generating an address field of the wake-up frame, and respectively indicates a receiving address and a sending address of the wake-up frame, thereby not only reducing the occurrence of data collision, but also improving the data throughput and spectrum utilization rate.
Meanwhile, the hash digest algorithm is adopted, so that the values of the PBSS ID and the PAID can be randomly determined, the repeatability that the PBSS ID and the PAID are the same is reduced, and the probability of communication collision caused by the fact that receiving or sending addresses are the same is greatly reduced.
When the AID is an association identifier assigned by the access point device when the station device and the access point device establish an association relationship, the association relationship between the station device and the access point device is indicated by 14 bits, the maximum value of the AID is 2007, and all values greater than 2007 are used as reserved values.
