In WUR (ieee802.11ba), in order to make the device more power-saving, its main communication interfaces are all in a power-off state and the secondary communication interfaces are in a power-on state.
For STAs (Stations) in the WUR state, since the secondary communication interface is in the power-on state, i.e., the communication state, to receive the wake-up message frame sent by the AP (Access Point), the primary communication interface of the station device is woken up to perform data communication, and when the AP in the association state with the STAs is in the power-saving state or in the leaving state, and the STAs are in the wakened state, the STAs can never wake up to perform data communication, which goes against the requirement of ieee802.11ba.

Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
A communication method of a wireless local area network for a station that has established an association with a first access point according to an embodiment of the present invention is described in detail below with reference to fig. 1 and 2.
As shown in fig. 1, the communication method for a wireless local area network of a station according to the present invention specifically includes the following steps:
step 102, when the station continuously does not receive the wake-up message frame from the first access point, receiving the first message frame from the second access point through the secondary communication interface of the station to wake up the primary communication interface of the station.
It will be appreciated that, in the process of a station having established an association with a first access point and waiting for the first access point to wake up its primary communication interface to receive downstream data, that is, the main communication interface of the station is in an awake state to wait for being awakened by the wake-up message frame of the first access point to receive downlink data, if the station does not continuously receive the wake-up message frame sent by the first access point for awakening the main communication interface of the station, i.e. the first access point has left its coverage area or has powered off, so that the station is in an indiscriminate state where it cannot receive the downlink data in time, in order to effectively avoid the station in the awake state from being in an indiscriminate state, then the first message frame sent from an access point other than the first access point (i.e., the second access point) can be received through the secondary communication interface of the station to wake up the primary communication interface of the station.
And 104, generating a second message frame, wherein the source address of the second message frame is the source address of the analyzed first message frame, and the medium access control address and the destination address of the site are the source addresses of the analyzed first message frame.
And step 106, sending the second message frame to the second access point through the main communication interface so as to establish an initial network access link with the second access point.
It can be understood that, further, the second access point can identify the location of the station by sending, to the second access point, a second message frame whose source address is a medium access control address (MAC address) of the station, so that the station can smoothly access the BSS of the second access point to establish an initial network access connection with the second access point, so that the station can receive downlink data in time, and the requirement of 802.11ba is met, so that the device is more power-saving, wherein the station acquires its source address as a destination address of the second message frame by parsing the first message frame, that is, it is ensured that the second message frame can be smoothly sent to the second access point.
Further, as shown in fig. 2, the communication method of the wireless local area network according to the above embodiment includes the following steps in addition to steps 102 to 106:
step 108, receiving a third message frame sent by the second access point in response to the second message frame through the primary communication interface, where a source address of the third message frame is a mac address of the second access point and a destination address thereof is a mac address of the station.
And step 110, establishing an initial network access link with the second access point according to the third message frame.
In this embodiment, in order to ensure that the station and the second access point can establish accurate association and complete the initial network access connection of the station, the station further receives a third message frame, where a source address sent by the second access point in response to the second message frame is a mac address of the second access point and a destination address is a mac address of the station, so that the station and the second access point can identify accurate positions of each other in time, and can complete authentication, key agreement and other processes according to the existing Wi-Fi standard flow to complete the initial network access connection.
Further, the access point informs the station of the transmission period of the wakeup message frame, and if the station does not receive the wakeup message frame of the access point in consecutive transmission periods, the station may determine that the AP leaves its coverage, specifically, the station and the access point may negotiate to determine the number of consecutive transmission periods, for example, consecutive 3 transmission periods, and if the station does not receive the wakeup message frame transmitted by the AP for more than the duration of the consecutive 3 transmission periods, the station may determine that the AP leaves its coverage.
Further, in any of the above embodiments, the first message frame comprises a WUR beacon frame, and the first message frame is a broadcast message frame; the second message frame comprises a detection request frame, an association request frame or an authentication request frame; the third message frame comprises a detection response frame, an association response frame or an authentication response frame, and the third message frame is a unicast message frame.
It can be understood that the first message frame received by the station from the second access point may be a WUR beacon frame transmitted in a many-to-many broadcast communication mode, so as to ensure that the station can receive the message frame transmitted by the station even if the station does not establish an association with the second access point, and the second access point can synchronize with the station through the WUR beacon frame and the station can also identify the network of the second access point through the beacon frame; the second message frame for requesting and responding to establish the initial network access connection between the station and the second access point may be a probe request frame, an association request frame or an authentication request frame, and the corresponding third message frame is a probe response frame, an association response frame or an authentication response frame sent in a one-to-one unicast communication mode, so as to improve the efficiency of the initial network access connection under the condition of definite object.
Further, in any of the above embodiments, a BSS color value in the physical preamble header of the first message frame is the same as a BSS color value in the physical preamble header of the second message frame.
It can be understood that, considering that in ieee802.11ba, neither the source address nor the destination address of the WUR message frame is a medium access control address, and therefore the station cannot resolve the medium access control address of the second access point after receiving the first message frame, and in order to establish the initial network access connection between the station and the second access point, the station needs to know the identity of the second access point of the sender to determine its location, the identity of the second access point of the receiver of the second message frame may be determined in a manner that the BSS color value in the physical preamble of the second message frame for requesting the initial network access connection is set to be the same as the BSS color value in the physical preamble of the first message frame, so as to avoid confusing the second access point with other access points using the same source address, and thus accurately send the second message frame to the second access point.
Specifically, the destination address of the second message frame is the source address of the first message frame, and may be a BSS color value or a partial MAC address of the second access point; and the source address and the destination address of the third message frame are respectively the MAC addresses of the second access point and the station, and further, the BSS color value in the physical lead code frame header of the third message frame is also the same as the BSS color value in the physical lead code frame header of the first message frame.
