Description

Method and device for waking up wireless device

The present application claims priority from the chinese patent application filed on 2017, 03, 02, under the name "a method and apparatus for wireless communication," application No. 201710121709.0, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a device for waking up a wireless device.

Background

The Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard organization plans to develop Wireless Fidelity (Wi-Fi) based internet of things standards with the goal of applying Wi-Fi technology to the field of internet of things, as well as mobile terminals and digital medical devices. However, the power consumption of the existing Wi-Fi communication module of the mobile terminal is too large, and thus it is very necessary to improve and reduce the power consumption of the Wi-Fi communication technology.

In order to solve the above problems, the IEEE 802.11 standard organization proposes an ultra-low power Wake-Up Radio/Receiver (WUR) technology that can reduce the average power consumption of the Wi-Fi communication technology and simultaneously realize On-Demand (On-Demand) real-time data transmission. Specifically, the WUR technology is to add a WUR module to a device, and when there is no data reception or transmission, a host communication module (e.g., a Wi-Fi module) of the device enters deep sleep, and turns on the WUR module to perform ultra-low power listening. For example, assume that an Access Point (AP) is an awake device, a Station (STA) is an awake device, a WUR module of the STA is in an operating state and can monitor a WUR message sent by the AP, and a host communication module (e.g., a Wi-Fi module) of the STA is in a sleep state. As shown in fig. 1, when an AP has data (e.g., Wi-Fi messages) to transmit to an STA, the AP may first send a WUR message to a WUR module of the STA, and after the WUR module of the STA receives the WUR message, if it is determined that the receiver address of the WUR message matches the address of the WUR of the STA and the WUR message is correct and real, a wake-up signal may be sent to a host communication module of the STA to wake up the host communication module of the STA.

When the AP has data to transmit to the STAs, that is, the AP needs to wake up the host communication modules of the STAs, the AP may send a WUR message carrying bitmap information to the WUR modules of the STAs, where each bit in the bitmap information corresponds to one STA; after receiving the WUP carrying the bitmap information, the STA may determine whether a value of a bit corresponding to the STA in the bitmap information is a preset value (e.g., whether a bit corresponding to the STA is at a position of "1"), and if the STA determines that the value of the bit corresponding to the STA is the preset value (e.g., whether the bit corresponding to the STA is at the position of "1"), the STA may send a wake-up signal to a main communication module of the STA to wake up the main communication module of the STA.

However, in the above wake-up mode, some malicious devices may pretend to be APs, and the AP is simulated to send WUR messages carrying bitmap information to a plurality of STAs, and the bit part or all of the bitmap information may be simply set to "1" so as to easily wake up the main communication modules of a large number of STAs at the same time, which may cause a large number of STAs to be maliciously woken up by the malicious devices, which may cause unnecessary waste of increasing power consumption of the STA of the wakened device, and decrease the battery life of the battery of the wakened device. Moreover, after the main communication modules of a large number of STAs are maliciously awakened, the STAs compete to send uplink messages on the air interface, which causes congestion of the air interface and waste of air interface resources.

Disclosure of Invention

The application provides a method and equipment for awakening wireless equipment, which can improve the safety of an STA awakening process by an AP and avoid unnecessary power consumption caused by malicious equipment awakening of the STA.

In a first aspect, the present application provides a method of waking up a wireless device, comprising: a first wireless device sends a first wake-up message carrying first identification information to first communication interfaces of a plurality of devices in a broadcast mode or a multicast mode, wherein the first identification information is used for identifying at least one device including a second wireless device in the plurality of devices, and the first wake-up message is used for indicating that the first communication interface of the device identified by the first identification information needs to be in a working state so as to receive a second wake-up message sent by the first wireless device subsequently; after sending the first wake-up message, the first wireless device sends a second wake-up message carrying second identification information to a first communication interface of at least one device including the second wireless device, where the second identification information is used to identify a device to be woken up by the first wireless device, the device to be woken up by the first wireless device includes the second wireless device, and the second wake-up message is used to instruct the device identified by the second identification information to wake up the second communication interface of the device.

Wherein the first wireless device (e.g., AP) may instruct a plurality of devices including the second wireless device (e.g., STA) to wake up its second communication interface using the first wake-up message and the second wake-up message. Thus, after receiving the first wake-up message, the second wireless device cannot determine whether to wake up the second communication interface of the second wireless device, and needs to wait for receiving the second wake-up message, and then can determine whether to wake up the second communication interface of the second wireless device according to the received second wake-up message; instead of directly waking up the second communication interface of the second wireless device according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving the wake-up message. The double confirmation awakening mechanism can increase the difficulty of maliciously awakening a large number of STAs by malicious equipment, improve the safety of the awakening process of the STAs by the AP and avoid unnecessary power consumption caused by maliciously awakening of the STAs by the malicious equipment.

With reference to the first aspect, in a first possible implementation manner, the first identification information includes first bitmap information, the first bitmap information includes at least two bits, the at least two bits in the first bitmap information correspond to each device group in at least two groups of devices in the multiple devices in a one-to-one manner, each device group in the at least two groups of devices includes at least one device, the first identification information is used to identify a device group corresponding to a bit whose median value in the first bitmap information is a first preset value, and the second wireless device is one device in a group of devices corresponding to a bit whose median value in the first bitmap information is a first preset value. The second identification information includes second bitmap information, the second bitmap information includes at least two bits, the at least two bits in the second bitmap information correspond to devices in a device group corresponding to bits whose median values in the first bitmap information are the first preset value, one to one, and the second identification information is used for identifying devices corresponding to bits whose median values in the second bitmap information are the second preset value.

Since at least two bits of the first bitmap information correspond to at least two groups of devices one to one, that is, each bit in the first bitmap information may correspond to one group of devices. Thus, the first wireless device (e.g. AP) may indicate, by setting a value of a bit in the first bitmap information, that the first communication interface of the device in the device group corresponding to the bit is kept in a working state, and waits for receiving the second wake-up device; and the first awakening message does not need to carry more identification information, so that the data volume carried in the first awakening message can be reduced. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the second wireless device (e.g., STA) more quickly, and the second wireless device can control the first communication interface to remain in the working state or switch from the working state to the sleeping state earlier.

Likewise, at least two bits of the second bitmap information may correspond to devices in a device group in a one-to-one manner, i.e., each bit in the second bitmap information may correspond to a device in the device group. Thus, the first wireless device (e.g., AP) may instruct the device corresponding to a bit to wake up its second communication interface (e.g., Wi-Fi interface) by setting the value of the bit in the second bitmap information; and the second awakening message does not need to carry more identification information, so that the data volume carried in the second awakening message can be reduced. When the amount of data carried in the second wake-up message is small, the second wake-up message can be transmitted to the second wireless device more quickly, and the STA can wake up the second communication interface earlier.

With reference to the first aspect, in a second possible implementation manner, the first identification information includes group address information of a device group in which the second wireless device is located. The second identification information includes third bitmap information, the third bitmap information includes at least two bits, the at least two bits in the third bitmap information correspond to the devices in the device group where the second wireless device is located one by one, and the second identification information is used for identifying the devices corresponding to the bits whose median value in the third bitmap information is the second preset value.

When a first wireless device (e.g., an AP) wants to wake up a plurality of devices (e.g., STAs) in a device group, the first wireless device may send a first wake-up message carrying group address information of the device group to the plurality of devices including the device group. The group address information of one device group is less than the identification information of a plurality of devices in the device group (such as the device identification of the STA or the interface identification of the WUR interface of the STA); therefore, the first wireless device sends the first wake-up message carrying the group address information of the device group to the multiple devices in the device group, which not only can identify the device group, but also can reduce the data volume carried in the first wake-up message. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the second wireless device quickly, and the second wireless device can control the first communication interface to be kept in the working state or be switched from the working state to the dormant state earlier. The technical effect of the "the first wireless device instructs the second wireless device to wake up the second communication interface thereof in a manner that the first wireless device carries the third bitmap information in the second wake-up message" may refer to a detailed description that the first wireless device instructs the second wireless device to wake up the second communication interface thereof in a manner that the second identifier information includes the second bitmap information ", which is not described herein again.

With reference to the first aspect, in a third possible implementation manner, the first identification information includes fourth bitmap information, the fourth bitmap information includes at least two bits, the at least two bits in the fourth bitmap information correspond to the multiple devices one to one, and the first identification information is used to identify a device to which a bit whose median value in the fourth bitmap information is a first preset value corresponds.

Since at least two bits in the fourth bitmap information correspond to the devices that receive the first wake-up message one-to-one, the first wireless device (e.g., AP) may instruct the device corresponding to each bit to control the first communication interface to be in the working state or the sleep state by setting the value of each bit in the fourth bitmap information; and the first awakening message does not need to carry more identification information, so that the data volume carried in the first awakening message can be reduced. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the second wireless device quickly, and the second wireless device can be in a working state or a sleeping state earlier than the WUR interface.

With reference to the first aspect, in a fourth possible implementation manner, the first identification information includes an interface identification of a first communication interface of at least one device including the second wireless device in the multiple devices, or includes a device identification of at least one device including the second wireless device in the multiple devices.

With reference to the first aspect, or the third possible implementation manner or the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner, the second identification information includes a device identifier of a device to be woken up by the first wireless device, or includes an interface identifier of a first communication interface of the device to be woken up by the first wireless device.

With reference to the first aspect or any one of the foregoing possible implementation manners, in a sixth possible implementation manner, the first wake-up message further carries first indication information, where the first indication information is used to indicate a time for the first wireless device to send the second wake-up message.

When receiving the first wake-up message, the second wireless device may first switch the first communication interface of the second wireless device from the operating state to the dormant state, and then switch the first communication interface of the second wireless device from the dormant state to the operating state at the time indicated by the first indication information, so as to receive the second wake-up message sent by the first wireless device. In this way, unnecessary waste of power consumption can be avoided.

With reference to the first aspect or any one of the foregoing possible implementation manners, in a seventh possible implementation manner, the first wake-up message further carries second indication information, where the second indication information is used to notify the second wireless device to: the first wireless device uses the first wake-up message and the second wake-up message to instruct the second wireless device to wake up a second communication interface of the second wireless device.

With reference to the first aspect or any one of the foregoing possible implementation manners, in an eighth possible implementation manner, in order to prevent a malicious device from being disguised as a first wireless device (e.g., an AP), the first wireless device is emulated to send the first wake-up message and the second wake-up message to multiple devices (e.g., STAs), so as to cause unnecessary waste of increasing power consumption of the wokened device, and the first wireless device and the second wireless device may dynamically negotiate first identification information and second identification information used when the first wireless device wakes up a second communication interface of the second wireless device next time. Specifically, after the first wireless device sends the first wake-up message, and then sends a second wake-up message to a first communication interface of at least one device, including the second wireless device, of the at least one device, the method of the present application may further include: the first wireless device receives a wake-up response message sent by the second wireless device through a second communication interface of the second wireless device, wherein the wake-up response message is used for indicating that the second communication interface of the second wireless device is in a working state; the first wireless device negotiates with the second wireless device first identification information and second identification information for use in waking up a second communication interface of the second wireless device the next time.

With reference to the second aspect, in a possible implementation manner, the communication interface may be further configured to receive, after sending the second wake-up message, a wake-up response message sent by the second wireless device through the second communication interface of the second wireless device, where the wake-up response message is used to indicate that the second communication interface of the second wireless device is in an operating state. The processor may be further configured to negotiate, with the second wireless device, first identification information and second identification information used when waking up a second communication interface of the second wireless device next time.

Thus, after receiving the first wake-up message, the at least one device may wake up its second communication interface to wait for receiving the second wake-up message or keep its second communication interface in a dormant state; however, the second communication interface of the device that has woken up the second communication interface is not always in the working state, but the device may determine whether the second communication interface of the device needs to be in the working state after receiving the second wake-up message; instead of receiving a wake-up message, the second communication interface of the STA is woken up and the Wi-Fi interface of the STA is kept in a working state according to the value of the corresponding bit in the bitmap information carried in the wake-up message.

Detailed Description

The terms "first" and "second" and the like in the description of the present invention and the drawings are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of the objects. For example, the first wireless device and the second wireless device are different wireless devices, and the first indication information and the second indication information may be different indication information.

The method for waking up the wireless device provided by the embodiment of the invention can be applied to the process that the first wireless device wakes up one or more devices including the second wireless device.

Illustratively, the first wireless device in the embodiments of the present invention may be an AP, and the one or more devices may be one or more STAs (i.e., the second wireless device may be a STA).

Fig. 2 is a schematic diagram of a Network architecture of a Wireless Local Area Network (WLAN) 200 to which a method for waking up a Wireless device according to an embodiment of the present invention is applied. As shown in fig. 2, the WLAN 200 may include an AP 201 and one or more STAs.

Illustratively, the one or more STAs may be devices such as a mobile phone 202, a camera 203, a computer 204, a display device 205 (e.g., a television, a computer display, etc.), a tablet, a wearable device, a printer, etc. as shown in fig. 2. For convenience of description, only a partial example of the STA is given in fig. 2, and the STA according to the embodiment of the present invention includes but is not limited thereto.

The AP 201 may form a Basic Service Set (BSS) with the one or more STAs. The AP in the BSS (i.e., AP 201) may communicate with any STA in the BSS.

Within the coverage Area 211 of the AP 201 shown in fig. 2, a Basic Service Area (BSA) may be formed, the WLAN 200 may be connected to a Distributed System (DS) in a wired or wireless manner, and a plurality of APs 201 may form an Extended Service Set (ESS) in this manner. Thus, the AP 201 may then be in communication with one or more STAs in the ESS.

It should be noted that the network architecture to which the method of the embodiment of the present invention is applied is not limited to the architecture shown in fig. 2. For example, the method of the embodiment of the present invention may also be applied to a hotspot AP scene, P2P, and other scenes. For example, taking the mobile phone 202 and the display 205 as an example, the mobile phone 202 may turn on the hot spot mode to serve as an AP, and the display 205 serves as an STA to form a WLAN, in which the method of the embodiment of the present invention may be applied. Alternatively, the mobile phone 202 serves as a P2P Group Owner (GO), the display 205 serves as a P2P client, and the mobile phone 202 and the display 205 form a WLAN, in which the method of the embodiment of the present invention can be applied. Or, the mobile phone 202 serves as a NAN Anchor master, the display 205 serves as a NAN device, and the mobile phone 202 and the display 205 form a WLAN.

During the process of the AP 201 communicating with one or more STAs through the WLAN network, the Wi-Fi interface of one or more STAs shown in fig. 2 may enter a sleep state to save power. One or more STAs in the WLAN 200 are configured with a low power consumption auxiliary wake-up interface (e.g., WUR interface, as a receiver to wake up the Wi-Fi interface) in addition to the Wi-Fi interface. When the AP has data to transmit to the STA, the AP may send a WUR message to the WUR interface of the STA first, and instruct the WUR interface to wake up the Wi-Fi interface of the STA to receive the data subsequently sent by the AP.

The Wi-Fi interface and the WUR interface in the embodiment of the invention can respectively use one antenna to transmit signals; or, the two antennas can share one antenna for signal transmission, so as to save the cost of the equipment.

The WUR message may be a message that can be received and analyzed by a WUR interface, such as a Wake Up Packet (WUP) or a Wake Beacon frame (Wake Up Beacon, which may also be referred to as WUR Beacon). Alternatively, the WUR message may be another message with functionality to instruct the STA to wake up its Wi-Fi interface.

Taking the mobile phone 202 as an example, entering the Sleep state indicates that the Wi-Fi interface of the mobile phone 202 does not continuously receive air interface messages any more, and specifically may be entering a Doze state (Doze state) or a shallow Sleep state, that is, a baseband module and a Media Access Control (MAC) processor module of the Wi-Fi interface are kept on, a Radio Frequency (RF) module is turned off, or a Deep Sleep state (Deep Sleep), that is, the RF module, the baseband module, and the MAC processor module of the Wi-Fi interface are all turned off.

In the method for waking up a wireless device provided in the embodiment of the present invention, a first wireless device (e.g., an AP) may use two wake-up messages (e.g., a first wake-up message and a second wake-up message) to instruct a second wireless device (e.g., an STA) to wake up a second communication interface of the second wireless device. After receiving the first wake-up message, the second wireless device cannot determine whether to wake up the second communication interface of the second wireless device, and needs to wait for receiving the second wake-up message, and then can determine whether to wake up the second communication interface of the second wireless device according to the received second wake-up message; instead of directly waking up the second communication interface of the second wireless device according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving the wake-up message. The double confirmation awakening mechanism can increase the difficulty of maliciously awakening a large number of STAs by malicious equipment, improve the safety of the awakening process of the STAs by the AP and avoid unnecessary power consumption caused by maliciously awakening of the STAs by the malicious equipment.

It should be noted that, in this embodiment of the present invention, the second communication interface (e.g., Wi-Fi interface, main communication interface) of the second wireless device (e.g., STA) is a communication interface provided by a main communication module (e.g., Wi-Fi module) of the second wireless device, and the first communication interface (e.g., WUR interface, auxiliary wake-up interface) of the second wireless device (e.g., STA) is a communication interface provided by an auxiliary wake-up module (e.g., WUR module) of the second wireless device. The method of the embodiment of the present invention is described in detail by taking, as an example, the first wireless device as an AP, a plurality of devices to be woken up by the first wireless device, including the second wireless device, as STAs, the first communication interface is a WUR interface, and the second communication interface is a Wi-Fi interface.

Exemplarily, the embodiment of the present invention takes a scenario that the AP 301 in the Wi-Fi network 300 wakes up one or more STAs in its coverage area as shown in fig. 3 as an example, and illustrates a method for waking up a wireless device according to the embodiment of the present invention.

The Wi-Fi network 300 shown in fig. 3 may include an AP 301 and a plurality of STAs, which may include 7 STAs, such as STA1, STA 2, STA 3, and the like, shown in fig. 3. As shown in table 1, the device identifiers of 7 STAs, such as STA1, STA 2, STA 3, etc., are STA-1, STA-2, STA-3, … …, STA-7, respectively; the interface identifications of the WUR interfaces of 7 STAs such as STA1, STA 2, STA 3 and the like are WUR-1, WUR-2, WUR-3, … … and WUR-7 respectively; the interface identifications of the WUR interfaces of 7 STAs such as STA1, STA 2, STA 3 and the like are Wi-Fi-1, Wi-Fi-2, Wi-Fi-3, … … and Wi-Fi-7 respectively.

As shown in fig. 3, the 7 STAs may belong to three device groups: device group x, device group y, and device group z. As shown in table 1, the group address information of the device group x is x, and the device group x includes STA1, STA 2, and STA 3; the group address information of the equipment group y is y, and the equipment group y comprises STA 4 and STA 5; the group address information of the device group z is z, and the device group z includes STA 6 and STA 7.

In the embodiment of the invention, the group address information of the STA can be allocated to the STA in the Wi-Fi communication process between the AP and the STA. For example, the group address information of the STA may be a multicast address allocated by the AP to an apparatus group when the AP transmits data to STAs in the apparatus group in a multicast manner. Alternatively, the group address information of the STAs may be generated by the STAs according to a preset group address information generation rule, and STAs having the same group address information may be considered as STAs of the same device group. For example, the STA may obtain group address information of the STA by using a hash algorithm or by intercepting preset bits in identification information such as a Media Access Control (MAC) address or a WUR ID of the STA. Alternatively, the group address information of the STA may be determined by the STA according to the time information of the BSS in which the STA joins the AP.

It should be noted that, the group address information in the embodiment of the present invention may also be referred to as group identification information, and the group identification information may be a number information, a numerical value information, a letter information, and the like, which is not limited in this respect.

When an STA initiates an Association Request (Association Request) to the AP, the AP feeds back an Association Response frame (Association Response) and assigns an Association Identifier (AID) to the STA. When the AP allocates AIDs to the STAs, the APs may allocate AIDs to the STAs in sequence from 1 according to the sequence of association between the STAs and the AP; therefore, the AP 301 may allocate an AID that can uniquely identify each STA among the 7 STAs.

As shown in table 1, when the AP 301 establishes Association with STA1, the Association Identifier (AID) allocated to STA1 is AID-1, when the AP 301 establishes Association with STA 2, the AID allocated to STA 2 is AID-2, when the AP 301 establishes Association with STA 3, the AID allocated to STA 3 is AID-3, … …, and when the AP 301 establishes Association with STA 7, the AID allocated to STA 7 is AID-7.

TABLE 1

For convenience of description, only some examples of the STA are given in fig. 3, and the STA according to the embodiment of the present invention includes but is not limited thereto. For the detailed description of the STA shown in fig. 3, reference may be made to the description of the STA in fig. 2 according to the embodiment of the present invention, and details are not repeated here.

Based on the scenario that the AP 301 wakes up one or more STAs within its coverage area as shown in fig. 3, in a first application scenario of the embodiment of the present invention, the AP 301 may wake up the Wi-Fi interfaces of the one or more STAs to be woken up by sending a first wake-up message and a second wake-up message to the WUR interfaces of the one or more STAs to be woken up by the AP 301. The first wake-up message and the second wake-up message may be the same or different.

As shown in fig. 4, a method for waking up a wireless device according to an embodiment of the present invention may include S401-S410:

s401: the AP sends a first awakening message to the WUR interfaces of the STAs in a broadcast mode or a multicast mode, wherein the first awakening message carries first identification information, the first identification information is used for identifying at least one STA including the STA to be awakened in the STAs, and the first awakening message is used for indicating that the WUR interface of the STA identified by the first identification information needs to be in a working state so as to receive a second awakening message sent by the AP subsequently.

For example, the AP may send a first wake-up message to the WUR interfaces of the plurality of STAs in a broadcast manner according to a broadcast address of the WUR interface of the STA to be woken up by the AP; or, the first wake-up message may be sent to the WUR interfaces of the plurality of STAs in a multicast manner according to a multicast address of the WUR interface of the STA to be woken up by the AP; or, the first wake-up message may carry indication information indicating that the first wake-up message is a broadcast message or a multicast message.

Illustratively, the AP may send the first wake-up message to the WUR interfaces of the plurality of STAs in a broadcast manner or a multicast manner through the Wi-Fi interface of the AP. Alternatively, if a WUR module is configured in the AP, the AP may send a first wake-up message to the WUR interfaces of the plurality of STAs through the WUR interface provided by the WUR module.

The first wake-up message carries first identification information, where the first identification information is used to identify at least one STA including the STA to be woken up among the multiple STAs, and the first wake-up message is used to indicate that a WUR interface of the STA identified by the first identification information (i.e., the at least one STA) needs to be in a working state to receive a second wake-up message subsequently sent by the AP 301.

For example, the first wake-up message in the embodiment of the present invention may be a WUR Beacon (Beacon) message, or the first wake-up message may be another broadcast message or a multicast message. Or, the first wake-up message may be a wake-up packet message carrying broadcast address or multicast address or group address information of a WUR interface of the STA to be woken up by the AP. Alternatively, the first wake-up message may be a wake-up packet message carrying group address information of the STA to be woken up by the AP.

Fig. 5 is a schematic diagram of a message structure of a wake-up message according to an embodiment of the present invention. The first wake-up message provided by the embodiment of the present invention may include at least the first identification information 504 in the WUR message as shown in fig. 5.

As shown in fig. 5, the first wake-up message may further include one or more of an original preamble 501, a WUR reference Signal 502, a WUR signaling field (Signal, SIG)503, and a Frame Check Sequence (FCS) 505.

Among other things, the original preamble 501 may be used to announce an occupied channel on a Wi-Fi channel to surrounding Wi-Fi devices, thereby better co-existing with the Wi-Fi devices. The WUR reference signal 502 may indicate to the STA that the first wake-up message is a WUR message. The WUR SIG may include information such as first indication information indicating a time when the AP transmits the second wake-up message, second indication information, and type information indicating a WUR message in the embodiment of the present invention. The FCS may be used for the STA receiving the WUR message to perform frame check to determine whether the WUR message is received correctly. If the FCS check fails, the STA may discard the WUR message.

S402: the plurality of STAs receive a first wake-up message transmitted by the AP in a broadcast manner or a multicast manner through the WUR interfaces of the plurality of STAs.

S403: the STA receiving the first wake-up message determines whether the STA is one of the STAs identified by the first identification information.

Specifically, if the STA determines that the STA is one of the STAs identified by the first identification information, the STA may continue to perform S404; if the STA determines that the STA is not one of the STAs identified by the first identification information, it may proceed to S409:

s404: the STA keeps the WUR interface of the STA in an active state.

S405: and after sending the first wake-up message, the AP sends a second wake-up message to a WUR interface of at least one STA including the STA to be woken up.

The second wake-up message carries second identification information, where the second identification information is used to identify one or more STAs to be waked up by the AP, and the second wake-up message is used to instruct the STA identified by the second identification information to wake up a Wi-Fi interface of the STA.

For example, the second wake-up message in the embodiment of the present invention may be a WUR Beacon (Beacon) message, or the second wake-up message may be another unicast message, a broadcast message, or a multicast message. Alternatively, the second wake-up message may be a wake-up packet message carrying broadcast address or multicast address or group address information of the WUR interface of the STA to be woken up by the AP.

Fig. 6 is a schematic diagram of a message structure of a wake-up message according to an embodiment of the present invention. The second wake-up message provided in the embodiment of the present invention may include at least the second identification information 604 in the wake-up message shown in fig. 6. As shown in fig. 6, the second wake-up message may also include one or more of an original preamble 601, a WUR reference signal 602, a WUR SIG603, and an FCS 605. For specific functions of each part in the second wake-up message shown in fig. 6, reference may be made to the detailed description of the first wake-up message shown in fig. 5 in the embodiment of the present invention, which is not described herein again.

S406: and at least one STA including the STA to be woken in the at least one STA receives a second wake-up message through a WUR interface of the at least one STA.

S407: the STA which receives the second wake-up message determines whether the STA is one of the STAs identified by the second identification information.

Specifically, if the STA receiving the second wake-up message determines that the STA is one of the STAs identified by the second identification information, S408 may be continuously performed; if the STA receiving the second wakeup message determines that the STA is not one of the STAs identified by the second identification information, S409 and S410 may be continuously performed.

S408: the STA wakes up the Wi-Fi interface of the STA.

S409: the STA switches the WUR interface of the STA from an operating mode to a dormant state.

S409 is optional, and the STA may not execute S409 but keep its WUR interface in an operating state.

S410: the STA keeps the Wi-Fi interface of the STA in a sleep state.

In the method for waking up a wireless device provided in the embodiment of the present invention, an AP may instruct one or more STAs to wake up a Wi-Fi interface thereof using a first wake-up message and a second wake-up message. After receiving the first wake-up message, the STA cannot determine whether to wake up the Wi-Fi interface of the STA, and needs to wait for receiving the second wake-up message, and then can determine whether to wake up the Wi-Fi interface of the STA according to the received second wake-up message; instead of directly waking up the Wi-Fi interface of the STA according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving the wake-up message. The double confirmation awakening mechanism can increase the difficulty of maliciously awakening a large number of STAs by malicious equipment, improve the safety of the awakening process of the STAs by the AP and avoid unnecessary power consumption caused by maliciously awakening of the STAs by the malicious equipment.

In a first application scenario of the embodiment of the present invention, an AP may wake up one or more STAs by carrying the same or different contents in a first wake-up message and a second wake-up message.

In a first implementation manner of the first application scenario, the AP may wake up one or more STAs by including the first bitmap information in the first identification information and including the second bitmap information in the second identification information.

The first identification information includes at least two bits included in the first bitmap information, the at least two bits in the first bitmap information correspond to each device group in at least two groups of devices (i.e., at least two groups of STAs) in the plurality of devices (the plurality of STAs receiving the first wake-up message), each device group in the at least two groups of devices includes at least one device (i.e., at least one STA), the first identification information is used for identifying a group of devices (i.e., a group of STAs) to which bits whose values in the first bitmap information are the first preset value correspond, and the second wireless device (i.e., a STA to be woken up by the AP) is one device in a group of devices in the at least two groups of devices.

For example, based on the scenario that the AP 301 wakes up one or more STAs within its coverage as shown in fig. 3, the first bitmap information may include three bits "abc" and values of the three bits "abc" (e.g., a is 1, b is 1, and c is 0), a first bit "a" of the three bits "abc" may correspond to the device group x, a second bit "b" may correspond to the device group y, and a third bit "c" may correspond to the device group z. The first preset value may be 1 or 0, and a specific value of the first preset value may be determined by negotiation between the AP and the STA. For example, when the first preset value is 1, if the first bitmap information is "110", the first identification information may be used to identify the device group x and the device group y; when the first preset value is 0, if the first bitmap information is "110", the first identification information may be used to identify the device group z.

The AP 301 may set, in the first bitmap information, a value of a bit corresponding to a device group in which the STA to be waken by the AP 301 is located to be a first preset value. Assuming that the first preset value is 1, the AP 301 is to wake up STA1 and STA 3 in the device group x and STA 5 in the device group y, then, as shown in fig. 7, the first wake-up message may carry first bitmap information "110", i.e., a equals 1, b equals 1, and c equals 0. At this time, the first identification information may be used to identify the device group x and the device group y, and the first wake-up message may be used to indicate that the WUR interfaces of the STAs (i.e., STA 1-STA 3) in the device group x and the STAs (i.e., STA 4 and STA 5) in the device group y are in an operating state.

In a first implementation manner of the first application scenario, as shown in fig. 8, S403 in fig. 4 may be replaced by S403 a:

s403 a: and the STA receiving the first wake-up message judges whether the value of the bit corresponding to the group of the STA in the first bitmap information carried in the first wake-up message is a first preset value or not.

Specifically, if the STA receiving the first wakeup message determines that the value of the bit corresponding to the group where the STA is located in the first bitmap information carried in the first wakeup message is a first preset value, S404 may be continuously executed; if the STA receiving the first wake-up message determines that the value of the bit corresponding to the group where the STA is located in the first bitmap information carried in the first wake-up message is not the first preset value, S409 may be continuously executed:

based on the above example, as shown in fig. 7, since the first identification information includes the first bitmap information "110", an STA (e.g., STA1 or STA 2) in the device group x may determine that a value of a bit corresponding to the device group x in the first bitmap information "110" is a first preset value (i.e., 1), and may keep the WUR interface of the STA in an operating state (e.g., on), i.e., continue to perform S404; an STA (e.g., STA 4 or STA 5) in the device group y may determine that a value of a bit corresponding to the device group y in the first bitmap information "110" is a first preset value (i.e., 1), and may keep the WUR interface of the STA in a working state, i.e., continue to execute S404; however, an STA (e.g., STA 6) in the device group z may determine that the value of the bit corresponding to the device group z in the first bitmap information "110" is not the first preset value, and may switch the WUR interface of the STA from an operating state (e.g., on) to a sleep state (e.g., off), i.e., continue to execute S409.

The second identification information includes second bitmap information, the second bitmap information includes at least two bits, the at least two bits in the second bitmap information correspond to devices in a device group corresponding to bits with a first preset value in a one-to-one manner, and the second identification information is used for identifying devices corresponding to bits with a second preset value.

For example, based on the scenario that the AP 301 wakes up one or more STAs in its coverage area as shown in fig. 3, since the first bitmap information is "110", the AP 301 may send a second wake-up message to the STAs in the device group x and the device group y.

Taking the device group x as an example, the second bitmap information may include three bits "def" and values of the three bits "def" (e.g., d is 1, e is 0, and f is 1), a first bit "d" of the three bits "def" may correspond to STA1 in the device group x, a second bit "e" may correspond to STA 2 in the device group x, and a third bit "f" may correspond to STA 3 in the device group x.

Taking the device group y as an example, the second bitmap information may include two bits "gh" and values of the two bits "gh" (e.g., g is 0, h is 0), a first bit "g" of the two bits "gh" may correspond to STA 4 in the device group y, and a second bit "h" may correspond to STA 5 in the device group y.

The second preset value may be 1 or 0, and a specific value of the second preset value may be determined by negotiation between the AP and the STA.

The AP 301 may set a value of a bit corresponding to the STA to be woken up by the AP 301 in the second bitmap information to a second preset value.

Assuming that the second preset value is 1, the AP 301 wakes up STA1 and STA 3 in the device group x; then, as shown in fig. 7, the AP 301 may send a second wake-up message carrying second bitmap information "101" (i.e., d is 1, e is 0, and f is 1) to the STAs in the device group x. At this time, the second identification information carried in the second wake-up message may be used to identify the STA1 and the STA 3, and the second wake-up message may be used to instruct the STA1 and the STA 3 to wake up the Wi-Fi interface thereof.

Assuming that the second preset value is 1, the AP 301 wakes up STA 5 in the device group y; then, as shown in fig. 7, the AP 301 may transmit a second wake-up message carrying second identification information including second bitmap information "01" (i.e., g ═ 0, h ═ 0) to the STA 5 in the device group y. At this time, the second identification information carried in the second wake-up message may be used to identify the STA 5, and the second wake-up message may be used to instruct the STA 5 to wake up the Wi-Fi interface thereof.

In a first implementation manner of the first application scenario, as shown in fig. 8, S407 in fig. 4 may be replaced with S407 a:

s407 a: and the STA receiving the second wake-up message judges whether the value of the bit corresponding to the STA in the second bitmap information is a second preset value.

Specifically, if the STA that receives the second wakeup message determines that the value of the bit corresponding to the STA in the second bitmap information is the second preset value, S408 may be continuously performed; if the STA receiving the second wake-up message determines that the value of the bit corresponding to the STA in the second bitmap information is not the second preset value, S409 may be continuously performed:

based on the above example, as shown in fig. 7, the second identification information received by the STAs in the device group x includes the second bitmap information "101"; then, STA1 in the device group x may determine that the value of the bit corresponding to STA1 in the second bitmap information "101" is a second preset value (i.e., 1), and may continue to execute S408 to wake up the Wi-Fi interface of STA 3 (i.e., switch the Wi-Fi interface of STA 3 from the sleep state to the working state); the STA 3 in the device group x may determine that the value of the bit corresponding to the STA 3 in the second bitmap information "101" is the second preset value, and may wake up the Wi-Fi interface of the STA 3, that is, continue to execute S408; and the STA 2 in the device group x may determine that the value of the bit corresponding to the STA 2 in the second bitmap information "101" is not the second preset value, then the WUR interface of the STA may be switched from the working state (e.g., on) to the sleep state (e.g., off), that is, S409 is continuously performed, and the Wi-Fi interface of the STA is kept in the sleep state (e.g., off), that is, S410 is performed.

It should be noted that, the value of the third bit in the first bitmap information "110" is 0, which indicates that the STA in the device group z is not the STA to be woken by the AP 301, and therefore the AP 301 may not send the second wake-up message to the STA in the device group z.

In a first implementation manner of the first application scenario, at least two bits of the first bitmap information correspond to each device group in at least two groups of devices in a one-to-one manner, that is, each bit in the first bitmap information may correspond to a group of devices. In this way, the AP may indicate that the WUR interface of the device in the device group corresponding to a bit is in a working state by setting a value of the bit in the first bitmap information, and waits for receiving the second wake-up device; and the first awakening message does not need to carry more identification information, so that the data volume carried in the first awakening message can be reduced. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the STA quickly, and the STA can keep its WUR interface in a working state or enter a sleep state earlier.

Likewise, at least two bits of the second bitmap information may correspond to devices in a device group in a one-to-one manner, i.e., each bit in the second bitmap information may correspond to a device in the device group. In this way, the AP can instruct the device corresponding to a bit to wake up its Wi-Fi interface by setting the value of the bit in the second bitmap information; and the second awakening message does not need to carry more identification information, so that the data volume carried in the second awakening message can be reduced. When the amount of data carried in the second wake-up message is small, the second wake-up message can be transmitted to the STA quickly, and the STA can wake up the Wi-Fi interface earlier.

In a second implementation manner of the first application scenario, the AP may wake up the one or more STAs by carrying group address information of a device group in which the one or more STAs to be woken up by the AP are located in the first wake-up message and carrying third bitmap information in the second wake-up message.

The second implementation manner of the first application scenario:

the first identification information carried in the first wake-up message in S401-S403 may include group address information of a device group in which the STA to be woken up by the AP is located. For example, based on the scenario shown in fig. 3 in which the AP 301 wakes up one or more STAs within its coverage area, assuming that the AP 301 is to wake up STA1 and STA 3 in the device group X and STA 5 in the device group Y, then, as shown in fig. 9, the first wake-up message may carry group address information X of the device group X and group address information Y of the device group Y. At this time, the first identification information may be used to identify the device group x and the device group y, and the first wake-up message may be used to indicate that the WUR interfaces of the STAs (i.e., STA 1-STA 3) in the device group x and the STAs (i.e., STA 4 and STA 5) in the device group y are in an operating state. Since the AP 301 does not need to wake up any STA in the device group Z, the group address information Z of the device group Z is not included in the first identification information.

In a second implementation manner of the first application scenario, as shown in fig. 10, S403 in fig. 4 may be replaced by S403 b:

s403 b: the STA receiving the first wake-up message judges whether the first identification information carried in the first wake-up message includes the group address information of the group in which the STA is located.

Specifically, if the STA receiving the first wake-up message determines that the first identification information carried in the first wake-up message includes the group address information of the group in which the STA is located, S404 may be continuously performed; if the STA receiving the first wake-up message determines that the first identification information carried in the first wake-up message does not include the group address information of the group in which the STA is located, S409 may be continuously performed:

based on the above example, as shown in fig. 9, the first identification information carried in the first wake-up message includes group address information X of the device group X and group address information Y of the device group Y; then, the STA in the device group x (e.g., STA1 or STA 2) and the STA in the device group y (e.g., STA 4 or STA 5) may keep the WUR interface of the STA in an operating state (e.g., on), i.e., continue to perform S404. As shown in fig. 9, since the first identification information carried in the first wake-up message does not include the group address information Z of the device group Z, an STA (e.g., STA 6) in the device group Z may switch the WUR interface of the STA from an operating state (e.g., on) to a sleep state (e.g., off), i.e., continue to execute S409.

The second identification information includes third bitmap information, the third bitmap information includes at least two bits, the at least two bits in the third bitmap information correspond to devices in a device group where the STA to be awakened by the AP is located, that is, the at least two bits in the third bitmap information correspond to devices in a device group corresponding to the group address information included in the first identification information, and the second identification information is used for identifying devices corresponding to bits with a second preset value.

For example, based on the scenario that the AP 301 wakes up one or more STAs in its coverage area as shown in fig. 3, since the first identification information includes the group address information X of the device group X and the group address information Y of the device group Y, the AP 301 may send a second wake-up message to the STAs in the device group X and the device group Y.

The method for instructing, by the AP, the STA in the device group to wake up the Wi-Fi interface thereof through the second wake-up message carrying the third bitmap information may refer to a method for instructing, by the AP, the STA in the device group to wake up the Wi-Fi interface thereof through the second wake-up message carrying the second bitmap information, which is not described herein again in the embodiments of the present invention.

In a second implementation manner of the first application scenario, as shown in fig. 10, S407 in fig. 4 may be replaced with S407 b:

s407 b: and the STA receiving the second wake-up message judges whether the value of the bit corresponding to the STA in the third bitmap information carried in the second wake-up message is a second preset value.

Specifically, if the STA that receives the second wakeup message determines that the value of the bit corresponding to the STA in the third bitmap information carried in the second wakeup message is the second preset value, S408 may be continuously executed; if the STA receiving the second wake-up message determines that the value of the bit corresponding to the STA in the third bitmap information carried in the second wake-up message is not the second preset value, S409 and S410 may be continuously performed.

Based on the above example, as shown in fig. 9, the second identification information received due to the STAs in the device group x includes the third bitmap information "101"; then, STA1 in the device group x may determine that the value of the bit corresponding to STA1 in the third bitmap information "101" is the second preset value (i.e., 1), and may wake up the Wi-Fi interface of STA 3 (i.e., switch the Wi-Fi interface of STA 3 from the sleep state to the working state), i.e., continue to execute S408; the STA 3 in the device group x may determine that the value of the bit corresponding to the STA 3 in the third bitmap information "101" is the second preset value, and may wake up the Wi-Fi interface of the STA 3, that is, continue to execute S408; and the STA 2 in the device group x may determine that the value of the bit corresponding to the STA 2 in the third bitmap information "101" is not the second preset value, then the WUR interface of the STA may be switched from the working state (e.g., on) to the sleep state (e.g., off), that is, S409 is continuously executed, and the Wi-Fi interface of the STA is kept in the sleep state (e.g., off), that is, S410 is executed.

The AP may send a second wake-up message carrying second bitmap information or third bitmap information corresponding to the device group to the STAs in the device group in a multicast mode or a unicast mode. When the AP sends the second wake-up message carrying the second bitmap information or the third bitmap information in a multicast manner, the AP may carry the group address information or the group identifier of the device group corresponding to the second bitmap information or the third bitmap information in the second wake-up message.

In the second implementation manner of the first application scenario, when the AP wakes up the STAs in the device group, the AP may send a first wake-up message carrying the group address information of the device group to the STAs including the device group. The group address information of one device group is less than the identification information of a plurality of STAs in the device group (such as the device identification of the STA or the interface identification of the WUR interface of the STA); therefore, the AP sends the first wake-up message carrying the group address information of the device group to the STAs in the device group, which not only can identify the device group, but also can reduce the amount of data carried in the first wake-up message. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the STA quickly, and the STA can keep its WUR interface in a working state or enter a sleep state earlier.

At least two bits of the third bitmap information correspond to devices in a device group in a one-to-one manner, that is, each bit in the third bitmap information may correspond to one device in the device group. In this way, the AP may instruct the device corresponding to a bit to wake up its Wi-Fi interface by setting the value of the bit in the third bitmap information; and the second awakening message does not need to carry more identification information, so that the data volume carried in the second awakening message can be reduced. When the amount of data carried in the second wake-up message is small, the second wake-up message can be transmitted to the STA quickly, and the STA can wake up the Wi-Fi interface earlier.

For example, in the third implementation manner of the first application scenario, the AP may wake up one or more STAs by carrying the fourth bitmap information in the first wake-up message and carrying "device identifier of STA to be woken up by AP" or "interface identifier of WUR interface of STA to be woken up by AP" in the second wake-up message.

The third implementation manner of the first application scenario is as follows:

the fourth bitmap information includes at least two bits, the at least two bits in the fourth bitmap information correspond to the multiple devices one by one, and the first identification information is used for identifying the device corresponding to the bit with the first preset value.

The first wake-up message described in S401-S403 may carry fourth bitmap information, where the fourth bitmap information includes at least two bits, the at least two bits in the fourth bitmap information correspond to multiple devices (multiple STAs receiving the first wake-up message) one to one, and the first identification information is used to identify a device corresponding to a bit with a first preset value. The first preset value may be 1 or 0, and a specific value of the first preset value may be determined by negotiation between the AP and the STA.

In the first case of the third implementation, the AP may send the first wake-up message in a broadcast manner, where the fourth bitmap information carried in the first wake-up message may include bits corresponding to each STA in all the device groups as shown in fig. 3.

For example, based on the scenario that the AP 301 wakes up one or more STAs within its coverage as shown in fig. 3, the fourth bitmap information may include seven bits "abcdefg" and values of the seven bits "abcdefg" (e.g., a ═ 1, b ═ 0, c ═ 1, d ═ 0, e ═ 1, f ═ 0, and g ═ 0), a first bit "a" of the seven bits "abcdefg" may correspond to STA1, a second bit "b" may correspond to STA 2, a third bit "c" may correspond to STA 3, a fourth bit "d" may correspond to STA 4, a fifth bit "e" may correspond to STA 5, a sixth bit "f" may correspond to STA 6, and a second bit "g" may correspond to STA 7.

Assuming that the first preset value is 1, the AP 301 is to wake up STA1, STA 3 and STA 5, then, as shown in fig. 11 or fig. 12, the first wake-up message may carry fourth bitmap information "1010100", i.e., a is 1, b is 0, c is 1, d is 0, e is 1, f is 0, and g is 0. At this time, the first identification information may be used to identify STA1, STA 3, and STA 5, and the first wake-up message may be used to indicate that the WUR interfaces of STA1, STA 3, and STA 5 are in an operating state.

In the second case of the third implementation manner, the AP may send the first wake-up message in a multicast manner, in this case, the fourth bitmap information carried in the first wake-up message sent by the AP to the device group x shown in fig. 3 may include a bit corresponding to each STA in the device group x, and the fourth bitmap information carried in the first wake-up message sent by the AP to the device group y shown in fig. 3 may include a bit corresponding to each STA in the device group y.

For example, based on the scenario shown in fig. 3 in which the AP 301 wakes up one or more STAs in its coverage area, the fourth bitmap information carried in the first wake-up message sent by the AP to the device group x shown in fig. 3 may include three bits "abc" and values of the three bits "abc" (e.g., a is 1, b is 0, and c is 1), a first bit "a" of the three bits "abc" may correspond to STA1 in the device group x, a second bit "b" may correspond to STA 2 in the device group x, and a third bit "c" may correspond to STA 3 in the device group x. Assuming that the AP 301 is to wake up STA1, STA 3, the AP may transmit the fourth bitmap information "101" to the STAs in the device group x as shown in fig. 13 or fig. 14. Since the AP does not need to wake up the STAs in device group y and device group z, the AP does not need to send the first wake-up message to the STAs in device group y and device group z. At this time, the first identification information may be used to identify STA1 and STA 3, and the first wake-up message may be used to indicate that the WUR interfaces of STA1 and STA 3 are in an operating state.

In a third implementation manner of the first application scenario, as shown in fig. 15, S403 in fig. 4 may be replaced by S403 c:

s403 c: and the STA receiving the first wake-up message judges whether the value of the bit corresponding to the STA in the fourth bitmap information carried in the first wake-up message is a first preset value.

Specifically, if the STA that receives the first wakeup message determines that the value of the bit corresponding to the STA in the first bitmap information carried in the first wakeup message is a first preset value, S404 may be continuously executed; if the STA receiving the first wake-up message determines that the value of the bit corresponding to the STA in the first bitmap information carried in the first wake-up message is not the first preset value, S409 may be continuously executed:

based on the above example, as shown in fig. 11, since the first identification information includes the fourth bitmap information "1010100", then STA1, STA 3, and STA-5 may determine that the bit values of STA1, STA 3, and STA 5 in the fourth bitmap information "1010100" are the first preset value (i.e., 1), and may keep the WUR interface of the STA in the working state (e.g., on), i.e., continue to execute S404; and STA 2, STA 4, STA 6, and STA 7 may determine that the value of the bit corresponding to STA 2, STA 4, STA 6, and STA 7 in the fourth bitmap information "1010100" is not the first preset value (i.e., 1), and may switch the WUR interface of the STA from the working state (e.g., on) to the sleep state (e.g., off), i.e., continue to perform S409.

The second identification information carried in the second wake-up message includes "an apparatus identification of the STA to be woken up by the AP" or "an interface identification of a WUR interface of the STA to be woken up by the AP".

For example, the device identification of a STA may be MAC address information of the STA, or may be AID of the STA. Alternatively, the device identifier of a STA may also be an identifier that is obtained by the STA or the AP based on the MAC address information of the STA or the AID of the STA and can be used to uniquely identify the STA.

For example, based on the scenario that the AP 301 wakes up one or more STAs within its coverage as shown in fig. 3, as shown in fig. 11 or fig. 12, since the fourth bitmap information is "1010100", the AP 301 may transmit a second wake-up message to STA1, STA 3, and STA 5.

Wherein the AP may transmit the second wake-up message to STA1, STA 3, and STA 5 in a unicast manner or a broadcast manner. When the AP sends the second wake-up message to the STA1, the STA 3, and the STA 5 in a unicast manner, the AP may send the second wake-up message carrying the MAC-1, AID-1, or WUR-1 to the STA1 as shown in fig. 11, may send the second wake-up message carrying the MAC-3, AID-3, or WUR-3 to the STA 3 as shown in fig. 11, and may send the second wake-up message carrying the MAC-5, AID-5, or WUR-5 to the STA 5 as shown in fig. 11. When the AP sends the second wake-up message in a broadcast manner, as shown in fig. 12, the second wake-up message may carry MAC-1, MAC-3, and MAC-5, or the second wake-up message may carry AID-1, AID-3, and AID-5, or the second wake-up message may carry WUR-1, WUR-3, and WUR-5.

For example, based on the scenario that the AP 301 wakes up one or more STAs in its coverage area as shown in fig. 3, as shown in fig. 13 or fig. 14, since the fourth bitmap information is "101", the AP 301 may send a second wake-up message to STA1 and STA 3.

Likewise, the AP may transmit the second wake-up message to STA1 and STA 3 in a unicast manner or a broadcast manner. When the AP sends the second wake-up message to the STA1 and the STA 3 in a unicast manner, the AP may send the second wake-up message carrying the MAC-1, AID-1, or WUR-1 as shown in fig. 13 to the STA1, and may send the second wake-up message carrying the MAC-3, AID-3, or WUR-3 as shown in fig. 13 to the STA 3. When the AP sends the second wake-up message in a broadcast manner, as shown in fig. 14, the second wake-up message may carry MAC-1 and MAC-3, or the second wake-up message may carry AID-1 and AID-3, or the second wake-up message may carry WUR-1 and WUR-3.

In a third implementation manner of the first application scenario, as shown in fig. 15, S407 in fig. 4 may be replaced with S407 c:

s407 c: and the STA receiving the second wake-up message judges whether the second identification information carried in the second wake-up message comprises the equipment identification of the STA or the interface identification of the WUR interface of the STA.

Specifically, if the STA receiving the second wakeup message determines that the second identification information carried in the second wakeup message includes the device identification of the STA or the interface identification of the WUR interface of the STA, S408 may be continuously executed; if the STA receiving the second wake-up message determines that the second identification information carried in the second wake-up message does not include the device identifier of the STA or the interface identifier of the WUR interface of the STA, S409 may be continuously performed:

for example, based on the above example, as shown in any of fig. 11 to 14, since the MAC-1/AID-1/WUR-1 is carried in the second wake-up message received by the STA1, the STA1 may wake up the Wi-Fi interface of the STA1 (i.e., switch the Wi-Fi interface of the STA1 from the sleep state to the working state), and continue to execute S408.

In the third implementation manner of the first application scenario, since at least two bits in the fourth bitmap information correspond to the multiple devices receiving the first wake-up message one to one, the AP may indicate, by setting a value of each bit in the fourth bitmap information, that the device corresponding to each bit keeps its WUR interface in a working state or a sleep state; and the first awakening message does not need to carry more identification information, so that the data volume carried in the first awakening message can be reduced. When the amount of data carried in the first wake-up message is small, the first wake-up message can be transmitted to the STA quickly, and the STA can be in a working state or a sleeping state earlier than the WUR interface.

In a fourth implementation manner of the first application scenario, the AP may wake up one or more STAs by carrying "device identifiers of multiple STAs to be woken up by the AP" or "interface identifiers of WUR interfaces of multiple STAs to be woken up by the AP" in the first wake-up message, and carrying "device identifier of one STA to be woken up by the AP" or "interface identifier of a WUR interface of one STA to be woken up by the AP" in the second wake-up message.

The implementation manner of the first application scenario is four:

the first identification information carried in the first wake-up message described in S401-S403 may include "device identifications of multiple STAs to be woken up by the AP" or "interface identifications of WUR interfaces of multiple STAs to be woken up by the AP", and the second identification information carried in the second wake-up message may include "device identification of a STA to be woken up by the AP" or "interface identification of a WUR interface of a STA to be woken up by the AP".

Illustratively, assume that AP 301 is to wake up STA1, STA 3, and STA 5 based on the scenario shown in fig. 3 in which AP 301 wakes up one or more STAs within its coverage area.

In one case of the fourth implementation, as shown in fig. 16 or 17, the AP 301 may transmit a first wake-up message carrying "MAC-1, MAC-3, and MAC-5" or "AID-1, AID-3, and AID-5" or "WUR-1, WUR-3, and WUR-5" to a plurality of STAs (including STA 1-STA 7) including STA1, STA 3, and STA 5 in a broadcast manner; after receiving the first wake-up message, the STA1, the STA 3, and the STA 5 may determine that the first identification information carried in the first wake-up message includes an equipment identifier of the STA or an interface identifier of a WUR interface of the STA; then, STA1, STA 3, and STA 5 may keep their WUR interfaces in a working state (on); after receiving the first wake-up message, the STA 2, the STA 4, the STA 6, and the STA 7 may determine that the first identification information carried in the first wake-up message does not include the device identification of the STA or the interface identification of the WUR interface of the STA; STA 2, STA 4, STA 6, and STA 7 may then switch their WUR interfaces from an on state to an off state.

In another case of the fourth implementation, the AP may send, in a multicast manner, a first wake-up message carrying a device identifier of the STA to be woken up by the AP or an interface identifier of a WUR interface of the STA to be woken up by the AP to all STAs in the device group including the STA to be woken up by the AP.

For example, as shown in fig. 18 or fig. 19, the AP 301 may transmit a first wake-up message carrying "MAC-1 and MAC-3" or "AID-1 and AID-3" or "WUR-1 and WUR-3" to all STAs (STA 1-STA-3) in the device group x in which STA1 and STA 3 are located, and transmit a first wake-up message carrying "MAC-5" or "AID-5" or "WUR-5" to all STAs (STA 4-STA-5) in the device group y in which STA 5 is located. After receiving the first wake-up message, the STA1, the STA 3, and the STA 5 may determine that the first identification information carried in the first wake-up message includes an equipment identifier of the STA or an interface identifier of a WUR interface of the STA; then, STA1, STA 3, and STA 5 may keep their WUR interfaces in a working state (on); after receiving the first wake-up message, the STA 2 and the STA 4 may determine that the first identification information carried in the first wake-up message does not include the device identifier of the STA or the interface identifier of the WUR interface of the STA; then, STA 2 and STA 4 may switch their WUR interfaces from an on state to an off state.

In a case of the fourth implementation, as shown in fig. 16 or fig. 18, after the AP 301 sends the first wake-up message, it may send a second wake-up message carrying "MAC-1, MAC-3, and MAC-5" or "AID-1, AID-3, and AID-5" or "WUR-1, WUR-3, and WUR-5" to STA1, STA 3, and STA 5 in a multicast manner; after receiving the second wake-up message, the STA1, the STA 3, and the STA 5 may determine that the second identification information carried in the second wake-up message includes the device identification of the STA or the interface identification of the WUR interface of the STA; then, STA1, STA 3, and STA 5 may wake up their Wi-Fi interfaces to make their Wi-Fi interfaces in an active state (on).

In another case of the fourth implementation manner, as shown in fig. 17 or fig. 19, after sending the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-1 or AID-1 or WUR-1" to the STA1 in a unicast manner; after receiving the second wakeup message, the STA1 may determine that the second identification information carried in the second wakeup message includes the device identification of the STA or the interface identification of the WUR interface of the STA; then, STA1 may wake up its Wi-Fi interface to make its Wi-Fi interface in an active state (on). After sending the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-3 or AID-3 or WUR-3" to the STA 3 in a unicast manner; after receiving the second wakeup message, the STA 3 may determine that the second identification information carried in the second wakeup message includes the device identification of the STA or the interface identification of the WUR interface of the STA; then, STA 3 may wake up its Wi-Fi interface to make its Wi-Fi interface in an active state (on). After sending the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-5, AID-5, or WUR-5" to the STA 5 in a unicast manner; after receiving the second wake-up message, the STA 5 may determine that the second identification information carried in the second wake-up message includes the device identifier of the STA or the interface identifier of the WUR interface of the STA; STA 5 may then wake up its Wi-Fi interface to place its Wi-Fi interface in an active state (on).

Since the AP will not continue to send the second wake-up message to the STA 2, the STA 4, the STA 6, and the STA 7, the STA 2, the STA 4, the STA 6, and the STA 7 do not need to wake up their Wi-Fi interfaces.

After the AP sends the first wake-up message, the AP may not send the second wake-up message immediately; therefore, after receiving the first wake-up message, the STA to be woken up by the AP may not receive the second wake-up message until the time indicated by the first indication information even though the STA is always in an active state, which may cause unnecessary waste of power consumption of the STA. In order to further reduce unnecessary waste of STA power consumption, the first wake-up message may further carry first indication information, where the first indication information is used to indicate that the time for the AP to send the second wake-up message is received. For example, the first indication information may be contained in the WUR SIG 503 as shown in fig. 5. Before S403, the method according to the embodiment of the present invention may further include S701, and S404 may be replaced with S404 a:

s701: and the STA receiving the first wake-up message switches the WUR interface of the STA from the working state to the dormant state.

S404 a: and the STA controls the WUR interface of the STA to be switched from a sleep state to an operating state at the time indicated by the first indication information.

In the embodiment of the present invention, when receiving the first wake-up message, the STA may first switch the WUR interface of the STA from the working state to the dormant state, and then switch the WUR interface of the TA from the dormant state to the working state at the time indicated by the first indication information, so as to receive the second wake-up message sent by the AP. In this way, unnecessary waste of power consumption can be avoided.

Further, the first wake-up message may further carry second indication information, where the second indication information is used to notify the STA: the AP instructs the STA to wake up the STA's Wi-Fi interface using the first wake-up message and the second wake-up message. Before S403, the method of the embodiment of the present invention may further include S702, and S404 may be replaced with S404 a:

s702: and the STA receiving the first wake-up message determines that the first wake-up message also carries second indication information.

For example, the second indication information may be contained in the WUR SIG 503 as shown in fig. 5. The STA receiving the first wake-up message may determine that the first wake-up message further carries the second indication information when determining that the value of the preset bit in the WUR SIG 503 is 1 as shown in fig. 5. That is, it may be determined that the AP will instruct the STA to wake up the Wi-Fi interface of the STA using the first wake-up message and the second wake-up message, and the STA may keep the WUR interface of the STA in an active state.

Further, the first wake-up message may not carry the second indication information, but carry third indication information, where the third indication information may be used to notify the STA to: the AP instructs the STA to wake up the STA's Wi-Fi interface using the first wake-up message. When the first wake-up message carries the third identification information, the STA receiving the first wake-up message can directly wake up the Wi-Fi interface of the STA without waiting for receiving the second wake-up message.

For example, the third indication information may be included in the WUR SIG 503 shown in fig. 5, and an STA receiving the first wake-up message may determine that the first wake-up message also carries the third indication information when it is determined that the value of the preset bit in the WUR SIG 503 shown in fig. 5 is 0, and then may determine that the AP will instruct the STA to wake up the Wi-Fi interface of the STA using the first wake-up message, and the STA may directly wake up the Wi-Fi interface of the STA without waiting for receiving the second wake-up message. In the embodiment of the present invention, the AP may notify the AP to instruct the STA to wake up the Wi-Fi interface mode of the STA through the second indication information and the third indication information, namely "the AP instructs the STA to wake up the Wi-Fi interface of the STA using the first wake-up message and the second wake-up message" or "the AP instructs the STA to wake up the Wi-Fi interface of the STA using the first wake-up message", after receiving the first wake-up message carrying the second indication information or the third indication information, the above-described mode of the AP waking up the STA may be determined to avoid that when the AP instructs the STA to wake up the Wi-Fi interface of the STA using the first wake-up message, the second wake-up message is not continuously sent to the STA, after receiving the first wake-up message, the STA cannot wake up the Wi-Fi interface thereof in time because of waiting for receiving the second wake-up message, which results in failure of Wi-Fi data transmission between the AP and the STA.

Further, in order to prevent malicious devices from being disguised as APs, the emulated AP sends the first wake-up message and the second wake-up message to one or more STAs, which causes unnecessary waste of increasing power consumption of the STA that is a device being woken up, the AP and the STA may dynamically negotiate first identification information and second identification information used when the AP wakes up the Wi-Fi interface of the STA next time. After S408, the method according to the embodiment of the present invention may further include S703-S705:

s703: after waking up the Wi-Fi interface of the STA, the STA sends a wake-up response message to the AP, wherein the wake-up response message is used for indicating that the Wi-Fi interface of the STA is in a working state.

The fact that the Wi-Fi interface of the STA is in the working state can mean that the Wi-Fi interface of the STA can perform Wi-Fi data interaction with the AP. For example, the STA may send a PS-Poll frame to the AP through the Wi-Fi interface of the STA, or the STA may send a PS-Poll frame to the AP through the Wi-Fi interface of the STA after sleeping for a period of time. For example, the wake-up response message may be a PS-Poll frame.

S704: and the AP receives a wake-up response message sent by the STA through a Wi-Fi interface of the STA.

After receiving a wakeup response message sent by an STA through a Wi-Fi interface of the STA, the AP may determine that the Wi-Fi interface of the STA is in a working state, that is, the Wi-Fi interface of the STA may perform Wi-Fi data interaction with the AP.

S705: the AP negotiates with the STA about first identification information and second identification information used when the Wi-Fi interface of the STA is awakened next time.

The AP can perform Wi-Fi data interaction with the STA so as to negotiate first identification information and second identification information used when a Wi-Fi interface of the STA is awakened next time.

In the embodiment of the invention, after waking up the Wi-Fi interface of an STA, the AP can perform Wi-Fi data interaction with the STA, and negotiate the first identification information and the second identification information used when the Wi-Fi interface of the STA is woken up next time, namely, the first identification information and the second identification information used when the AP wakes up the Wi-Fi interface of the STA every time can be different. Therefore, the difficulty that the malicious device imitates the AP to maliciously awaken a large number of STAs by using the first awakening message and the second awakening message can be increased, the safety of the awakening process of the STAs by the AP is improved, and unnecessary power consumption caused by the fact that the STAs are maliciously awakened by the malicious device is avoided.

When the AP and the STA transmit the WUR message through the WUR interface of the STA to wake up the Wi-Fi interface of the STA (that is, the first wake-up message and the second wake-up message are both transmitted through the WUR interface), the WUR may not receive the WUR message in time because the transmission rate of the WUR message is low, and thus cannot wake up the Wi-Fi interface of the AP and the STA in time, and data transmission on the Wi-Fi interface to be woken up is affected.

In order to improve the efficiency of the AP indicating the STA to wake up the Wi-Fi interface, in a second application scenario of the embodiment of the present invention, the AP may instruct the STA to wake up the Wi-Fi interface by sending a first wake-up message to the WUR interface of one or more STAs to be woken up by the AP; and then, the AP sends a second wake-up message to the Wi-Fi interfaces of one or more STAs to be woken up by the AP, so that the STA receiving the second wake-up message determines whether to keep the Wi-Fi interfaces thereof in a working state according to the indication of the second wake-up message. As shown in fig. 20, the method for waking up a wireless device according to an embodiment of the present invention may include S2001-S2009:

s2001: the AP sends a first awakening message to the WUR interfaces of the STAs in a broadcasting mode or a multicasting mode, the first awakening message carries first identification information, the first identification information is used for identifying at least one STA including the STA to be awakened in the STAs, and the first awakening message is used for indicating that the WUR interface of the STA identified by the first identification information needs to awaken the Wi-Fi interface of the STA so as to receive a second awakening message sent by the AP subsequently.

In a second application scenario of the embodiment of the present invention, reference may be made to the related description in the first aspect of the embodiment of the present invention for a specific manner in which the AP sends the first wake-up message to the WUR interfaces of the multiple STAs and specific content of the first identification information, which is not described herein again.

The difference is that the first wake-up message in the first application scenario is used to indicate that the WUR interface of the STA identified by the first identification information needs to be in a working state, and the first wake-up message in the second application scenario is used to indicate that the WUR interface of the STA identified by the first identification information needs to wake up the Wi-Fi interface of the STA to receive a second wake-up message subsequently sent by the AP.

S2002: the plurality of STAs receive a first wake-up message transmitted by the AP in a broadcast manner or a multicast manner through the WUR interfaces of the plurality of STAs.

S2003: the STA receiving the first wake-up message determines whether the STA is one of the STAs identified by the first identification information.

Specifically, if the STA determines that the STA is one of the STAs identified by the first identification information, S2004 may be continuously performed; if the STA determines that the STA is not one of the STAs identified by the first identification information, the STA can switch the WUR interface of the STA from the working state to the dormant state and keep the Wi-Fi interface of the STA in the dormant state.

S2004: the STA wakes up the Wi-Fi interface of the STA.

S2005: and after sending the first wake-up message, the AP sends a second wake-up message to a WUR interface of at least one STA including the STA to be woken up.

In the second application scenario of the embodiment of the present invention, a specific manner in which the AP sends the second wake-up message to the WUR interface of at least one STA including the STA to be woken up and specific content of the second identification information in the at least one STA may refer to related description in the first application scenario of the embodiment of the present invention, and details of the embodiment of the present invention are not repeated here.

In contrast, the second wake-up message in the first application scenario is used to instruct the STA identified by the second identification information to wake up the Wi-Fi interface of the STA, and the second wake-up message in the second application scenario is used to instruct the Wi-Fi interface of the device identified by the second identification information to be in a working state.

For example, the second wake-up message in the second application scenario may be a WUR Beacon message or a TIM frame that carries a Traffic Indication Map (TIM) element. Alternatively, the second wake-up message in the second application scenario may be a specially defined Action Frame (Action Frame), and the Action Frame may carry bitmap information (e.g., second bitmap information).

Fig. 21 is a schematic diagram of a message structure of a second wake-up message according to an embodiment of the present invention. As shown in fig. 21, the second wake-up message may include one or more of a Physical Layer (PHY) header 2101, a MAC header 2102, a frame body 2103, and an FCS 2105. The TIM element 2104 is included in the frame body 2103, and the TIM element 2104 includes at least second identification information 2108. Of course, the TIM element 2104 may also include a TIM element identification 2106 and a length 2107.

For example, the second identification information 2108 shown in fig. 21 may be the second bitmap information in the embodiment of the present invention, or the second identification information 2108 may include a device identification of the STA to be woken by the AP or an interface identification of a Wi-Fi interface of the STA to be woken by the AP.

S2006: and at least one STA including the STA to be woken in the at least one STA receives a second wake-up message through a Wi-Fi interface of the at least one STA.

S2007: the STA which receives the second wake-up message determines whether the STA is one of the STAs identified by the second identification information.

Specifically, if the STA receiving the second wake-up message determines that the STA is one of the STAs identified by the second identification information, S2008 may be continuously performed; if the STA that receives the second wake-up message determines that the STA is not one of the STAs identified by the second identification information, execution may continue with S2009.

S2008: the STA keeps the Wi-Fi interface of the STA in an active state.

S2009: the STA switches the Wi-Fi interface of the STA from the working mode to the dormant state.

In the method for waking up a wireless device provided in the embodiment of the present invention, an AP may instruct one or more STAs to wake up a Wi-Fi interface thereof using a first wake-up message and a second wake-up message. Specifically, the STA receiving the first wake-up message may wake up its Wi-Fi interface to wait for receiving the second wake-up message or keep its Wi-Fi interface in a sleep state according to the indication of the first wake-up message; however, the Wi-Fi interface of the STA which has woken up the Wi-Fi interface is not always in the working state, but the Wi-Fi interface of the STA can be determined whether to be in the working state after receiving the second wake-up message; instead of waking up the Wi-Fi interface of the STA and keeping the Wi-Fi interface of the STA in a working state according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving the wake-up message. The double confirmation awakening mechanism can increase the difficulty of maliciously awakening a large number of STAs by malicious equipment, improve the safety of the awakening process of the STAs by the AP and avoid unnecessary power consumption caused by maliciously awakening of the STAs by the malicious equipment.

In a second application scenario of the embodiment of the present invention, the AP may wake up one or more STAs by carrying the same or different contents in the first wake-up message and the second wake-up message.

In a first implementation manner of the second application scenario, the AP may wake up one or more STAs by including the first bitmap information in the first identification information and including the second bitmap information in the second identification information. The specific contents of the first bitmap information and the second bitmap information in the second application scenario may refer to the related description in the first implementation manner of the second application scenario, and are not described herein again in the embodiment of the present invention.

In a first implementation manner of the second application scenario, as shown in fig. 22, S2003 in fig. 20 may be replaced with S403 a. After S403a is executed, if the STA that receives the first wake-up message determines that the value of the bit corresponding to the group where the STA is located in the first bitmap information carried in the first wake-up message is the first preset value, S2004 may be continuously executed; if the STA receiving the first wake-up message determines that the value of the bit corresponding to the group where the STA is located in the first bitmap information carried in the first wake-up message is not a first preset value, the STA can switch the WUR interface of the STA from a working state to a dormant state and keep the Wi-Fi interface of the STA in the dormant state. For example, based on the scenario that the AP 301 wakes up one or more STAs within its coverage area as shown in fig. 3, assuming that the first preset value is 1, the AP 301 is to wake up STA1 and STA 3 in the device group x and STA 5 in the device group y, then, as shown in fig. 23, since the first identification information includes the first bitmap information "110", the STA (e.g., STA1 or STA 2) in the device group x and the STA (e.g., STA 4 or STA 5) in the device group y may determine that the value of the bit corresponding to the device group (e.g., device group x or device group y) where the STA is located in the first bitmap information "110" is the first preset value (i.e., 1), and may wake up the Wi-Fi interface of the STA to make its Wi-Fi interface in an operating state (e.g., on), i.s 2004 continues to be executed; and an STA (e.g., STA 6) in the device group z may determine that the value of the bit corresponding to the device group z in the first bitmap information "110" is not the first preset value, and may switch the WUR interface of the STA from an operating state (e.g., on) to a sleep state (e.g., off), and keep its Wi-Fi interface in the sleep state. In a first implementation manner of the second application scenario, as shown in fig. 22, S2007 in fig. 20 may be replaced with S407 a. After performing S407a, if the STA that receives the second wake-up message determines that the value of the bit corresponding to the STA in the second bitmap information is the second preset value, S2008 may continue to be performed; if the STA receiving the second wake-up message determines that the value of the bit corresponding to the STA in the second bitmap information is not the second preset value, S2009 may be continuously performed.

Since the first bitmap information is "110", the AP 301 may send a second wake-up message to the STAs in the device group x and the device group y.

Taking the device group x as an example, assuming that the second preset value is 1, the AP 301 needs to wake up STA1 and STA 3 in the device group x; then, as shown in fig. 23, the AP 301 may send a second wake-up message carrying the second bitmap information "101" to the STAs in the device group x. At this time, the second identification information carried in the second wake-up message may be used to identify the STA1 and the STA 3, and the second wake-up message may be used to indicate that the Wi-Fi interfaces of the STA1 and the STA 3 are in the working state. The second identification information received due to the STAs in the device group x includes second bitmap information "101"; then, STA1 and STA 3 in the device group x may determine that the value of the bit corresponding to STA1 in the second bitmap information "101" is the second preset value (i.e. 1), and may continue to execute S2008 to keep the Wi-Fi interface thereof in the working state; and STA 2 in the device group x may determine that the value of the bit corresponding to STA 2 in the second bitmap information "101" is not the second preset value, then may switch the Wi-Fi of the STA from the working state (e.g., on) to the sleep state (e.g., off), i.e., continue to execute S2009.

In a second implementation manner of the second application scenario, the AP may wake up the one or more STAs by carrying group address information of a device group in which the one or more STAs to be woken up by the AP are located in the first wake-up message and carrying third bitmap information in the second wake-up message. Specific contents of the group address information and the third bitmap information of the device group in which the STA is located in the second application scenario may refer to the related description in the second implementation manner of the first application scenario, and details of the embodiment of the present invention are not described herein again.

In a second implementation manner of the second application scenario, S2003 in fig. 20 may be replaced with S403 b. After S403b is executed, if the STA that receives the first wake-up message determines that the first identification information carried in the first wake-up message includes the group address information of the group in which the STA is located, S2004 may be continuously executed; if the STA receiving the first wake-up message determines that the first identification information carried in the first wake-up message does not include the group address information of the group in which the STA is located, the STA may keep the Wi-Fi interface of the STA in a sleep state. Optionally, at this time, the STA may also switch the WUR interface of the STA from an operating state to a sleep state.

For example, based on the scenario that the AP 301 wakes up one or more STAs in its coverage area as shown in fig. 3, assuming that the AP 301 is to wake up STA1 and STA 3 in the device group X and STA 5 in the device group Y, then as shown in fig. 24, since the first identification information carried in the first wake-up message includes the group address information X of the device group X and the group address information Y of the device group Y; then, the STA in the device group x (e.g., STA1 or STA 2) and the STA in the device group y (e.g., STA 4 or STA 5) may wake up the Wi-Fi interface of the STA to make the Wi-Fi interface thereof in an active state (e.g., on), i.e., continue to execute S2004. As shown in fig. 24, since the first identification information carried in the first wake-up message does not include the group address information Z of the device group Z, an STA (e.g., STA 6) in the device group Z may keep a Wi-Fi interface of the STA in a sleep state (e.g., off), and switch the WUR interface of the STA from an operating state to the sleep state.

In a second implementation manner of the second application scenario, S2007 in fig. 20 may be replaced with S407 b. After S407a is executed, if the STA that receives the second wake-up message determines that the value of the bit corresponding to the STA in the third bitmap information carried in the second wake-up message is the second preset value, S2008 may continue to be executed; if the STA receiving the second wake-up message determines that the value of the bit corresponding to the STA in the third bitmap information carried in the second wake-up message is not the second preset value, S2009 may be continuously executed.

Since the first identification information carried in the first wake-up message includes the group address information X of the device group X and the group address information Y of the device group Y, the AP 301 may send a second wake-up message to the STAs in the device group X and the device group Y.

Taking the device group x as an example, assuming that the second preset value is 1, the AP 301 needs to wake up STA1 and STA 3 in the device group x; then, as shown in fig. 23, the AP 301 may send a second wake-up message carrying the third bitmap information "101" to the STAs in the device group x. At this time, the second identification information carried in the second wake-up message may be used to identify the STA1 and the STA 3, and the second wake-up message may be used to indicate that the Wi-Fi interfaces of the STA1 and the STA 3 are in the working state. The second identification information received due to the STAs in the device group x includes third bitmap information "101"; then, STA1 and STA 3 in the device group x may determine that the value of the bit corresponding to STA1 in the third bitmap information "101" is the second preset value (i.e., 1), and may continue to execute S2008 to keep the Wi-Fi interface thereof in the working state; and the STA 2 in the device group x may determine that the value of the bit corresponding to the STA 2 in the third bitmap information "101" is not the second preset value, then the Wi-Fi of the STA may be switched from the working state (e.g., on) to the sleep state (e.g., off), that is, S2009 continues to be executed.

In a third implementation manner of the second application scenario, the AP may wake up one or more STAs by carrying the fourth bitmap information in the first wake-up message and carrying the "device identifier of the STA to be woken up by the AP" or the "interface identifier of the WUR interface of the STA to be woken up by the AP" in the second wake-up message. The specific content of the device identifier of the STA and the fourth bitmap information in the second application scenario may refer to the related description in the third implementation manner of the first application scenario, and this is not repeated here in the embodiment of the present invention.

In a third implementation manner of the second application scenario, S403 in fig. 20 may be replaced with S403 c. After S403c is executed, if the STA that receives the first wake-up message determines that the value of the bit corresponding to the STA in the fourth bitmap information carried in the first wake-up message is the first preset value, S2004 may be continuously executed; if the STA receiving the first wake-up message determines that the value of the bit corresponding to the STA in the fourth bitmap information carried in the first wake-up message is not a first preset value, the WUR interface of the STA is switched from the working state to the dormant state, and the Wi-Fi interface of the STA is kept in the dormant state.

In the first case of the third implementation, the AP may send the first wake-up message in a broadcast manner, where the fourth bitmap information carried in the first wake-up message may include bits corresponding to each STA in all the device groups as shown in fig. 3. As shown in fig. 25 or fig. 25, the first wake-up message may carry fourth bitmap information "1010100". At this time, the first identification information may be used to identify the STA1, the STA 3, and the STA 5, and the first wake-up message may be used to instruct the STA1, the STA 3, and the STA 5 to wake up the Wi-Fi interface thereof, so that the Wi-Fi interface thereof is in a working state.

In a second case of the third implementation, the AP may send the first wake-up message in a multicast manner, where in this case, the fourth bitmap information carried in the first wake-up message sent by the AP to the device group x may include a bit corresponding to each STA in the device group x, and the fourth bitmap information carried in the first wake-up message sent by the AP to the device group y may include a bit corresponding to each STA in the device group y. Taking the device group x as an example, assuming that the AP 301 wants to wake up the device group x terminals STA1 and STA 3, as shown in fig. 27 or fig. 28, the AP may send a first wake-up message carrying the fourth bitmap information "101" to the STAs in the device group x. Since the AP does not need to wake up the STAs in the device group y and the device group z, the AP does not need to send the first wake-up message carrying the fourth bitmap information "101" to the STAs in the device group y and the device group z. At this time, the first identification information may be used to identify the STA1 and the STA 3, and the first wake-up message may be used to instruct the STA1 and the STA 3 to wake up the Wi-Fi interface thereof, so that the Wi-Fi interface thereof is in a working state.

In a third implementation manner of the second application scenario, S2007 in fig. 20 may be replaced with S407 c. After performing S407c, if the STA that receives the second wake-up message determines that the second identification information carried in the second wake-up message includes the device identification of the STA or the interface identification of the WUR interface of the STA, S2008 may be continuously performed; if the STA receiving the second wake-up message determines that the second identification information carried in the second wake-up message does not include the device identification of the STA or the interface identification of the WUR interface of the STA, S2009 may be continuously executed.

For example, based on the scenario that the AP 301 wakes up one or more STAs within its coverage as shown in fig. 3, as shown in fig. 25 or fig. 25, since the fourth bitmap information is "1010100", the AP 301 may transmit a second wake-up message to STA1, STA 3, and STA 5. When the AP sends the second wake-up message to the STA1, the STA 3, and the STA 5 in a unicast manner, the AP may send the second wake-up message carrying the MAC-1, AID-1, or WUR-1 shown in fig. 25 to the STA1, may send the second wake-up message carrying the MAC-3, AID-3, or WUR-3 shown in fig. 25 to the STA 3, and may send the second wake-up message carrying the MAC-5, AID-5, or WUR-5 shown in fig. 25 to the STA 5. When the AP sends the second wake-up message in a broadcast manner, as shown in fig. 25, the second wake-up message may carry MAC-1, MAC-3, and MAC-5, or the second wake-up message may carry AID-1, AID-3, and AID-5, or the second wake-up message may carry WUR-1, WUR-3, and WUR-5.

For example, based on the scenario that the AP 301 wakes up one or more STAs in its coverage area as shown in fig. 3, as shown in fig. 27 or fig. 28, since the fourth bitmap information is "101", the AP 301 may send a second wake-up message to STA1 and STA 3. The AP may transmit the second wake-up message to STA1 and STA 3 in a unicast manner or a broadcast manner. When the AP sends the second wake-up message to the STA1 and the STA 3 in a unicast manner, the AP may send the second wake-up message carrying the MAC-1, AID-1, or WUR-1 as shown in fig. 27 to the STA1, and may send the second wake-up message carrying the MAC-3, AID-3, or WUR-3 as shown in fig. 27 to the STA 3. When the AP sends the second wake-up message in a broadcast manner, as shown in fig. 28, the second wake-up message may carry MAC-1 and MAC-3, or the second wake-up message may carry AID-1 and AID-3, or the second wake-up message may carry WUR-1 and WUR-3. For example, based on the above example, as shown in any one of fig. 25 to 28, taking STA1 as an example, since the second wake-up message received by STA1 carries MAC-1/AID-1/WUR-1, STA1 may wake up the Wi-Fi interface of STA1 (i.e., switch the Wi-Fi interface of STA1 from the sleep state to the working state), and continue to execute S2008.

In a fourth implementation manner of the second application scenario, the AP may wake up one or more STAs by carrying "device identifiers of multiple STAs to be woken up by the AP" or "interface identifiers of WUR interfaces of multiple STAs to be woken up by the AP" in the first wake-up message, and carrying "device identifier of one STA to be woken up by the AP" or "interface identifier of WUR interface of one STA to be woken up by the AP" in the second wake-up message.

In one case of the fourth implementation, based on the scenario shown in fig. 3, assuming that the AP 301 is to wake up STA1, STA 3, and STA 5, as shown in fig. 29 or fig. 30, the AP 301 may transmit a first wake-up message carrying "MAC-1, MAC-3, and MAC-5" or "AID-1, AID-3, and AID-5" or "WUR-1, WUR-3, and WUR-5" to a plurality of STAs (including STA 1-STA 7) including STA1, STA 3, and STA 5 in a broadcast manner; after receiving the first wake-up message, STA1, STA 3, and STA 5 may determine that the first identification information carried in the first wake-up message includes the device identification of the STA or the interface identification of the WUR interface of the STA. Then, unlike fig. 16 or 17, STA1, STA 3, and STA 5 may wake up their Wi-Fi interfaces to put their Wi-Fi interfaces in an on state (on). After receiving the first wake-up message, STA 2, STA 4, STA 6, and STA 7 may determine that the first identification information carried in the first wake-up message does not include the device identification of the STA or the interface identification of the WUR interface of the STA.

In another case of the fourth implementation, the AP may send, in a multicast manner, a first wake-up message carrying a device identifier of the STA to be woken up by the AP or an interface identifier of a WUR interface of the STA to be woken up by the AP to all STAs in the device group including the STA to be woken up by the AP. Based on the scenario shown in fig. 3, assuming that the AP 301 is to wake up STA1, STA 3 and STA 5, as shown in fig. 31 or fig. 32, the AP 301 may send a first wake-up message carrying "MAC-1 and MAC-3" or "AID-1 and AID-3" or "WUR-1 and WUR-3" to all STAs (STA 1-STA-3) in the device group x where STA1 and STA 3 are located, and send a first wake-up message carrying "MAC-5" or "AID-5" or "WUR-5" to all STAs (STA 4-STA-5) in the device group y where STA 5 is located. Different from fig. 18 or fig. 19, after receiving the first wake-up message and determining that the first identification information carried in the first wake-up message includes the device identification of the STA or the interface identification of the WUR interface of the STA, the STA1, the STA 3, and the STA 5 may wake up the Wi-Fi interface thereof to make the Wi-Fi interface thereof in the working state (on).

In a case of the fourth implementation, as shown in fig. 29 or fig. 31, after the AP 301 sends the first wake-up message, it may send a second wake-up message carrying "MAC-1, MAC-3, and MAC-5" or "AID-1, AID-3, and AID-5" or "WUR-1, WUR-3, and WUR-5" to STA1, STA 3, and STA 5 in a multicast manner; different from fig. 29 or fig. 31, STA1, STA 3, and STA 5 may keep the Wi-Fi interface in the working state (on) after receiving the second wake-up message and determining that the second identification information carried in the second wake-up message includes the device identification of the STA or the interface identification of the WUR interface of the STA.

In another case of the fourth implementation, as shown in fig. 30 or fig. 32, after sending the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-1 or AID-1 or WUR-1" to the STA1 in a unicast manner; after receiving the second wakeup message, the STA1 may determine that the second identification information carried in the second wakeup message includes the device identification of the STA or the interface identification of the WUR interface of the STA; STA1 may then keep its Wi-Fi interface in an active state (on). After sending the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-3 or AID-3 or WUR-3" to the STA 3 in a unicast manner; after receiving the second wakeup message, the STA 3 may determine that the second identification information carried in the second wakeup message includes the device identification of the STA or the interface identification of the WUR interface of the STA; STA 3 may then keep its Wi-Fi interface in an active state (on).

Since the AP does not continue to send the second wake-up message to the STA 2, the STA 4, the STA 6, and the STA 7, the STA 2, the STA 4, the STA 6, and the STA 7 may keep their Wi-Fi interfaces in the sleep state. Further, in a second application scenario of the embodiment of the present invention, in order to further reduce unnecessary waste of STA power consumption, the first wake-up message may further carry first indication information, where the first indication information is used to indicate that the time for the AP to send the second wake-up message is received. For example, the first indication information may be contained in the WUR SIG 503 as shown in fig. 5. Before S2003, the method of the embodiment of the present invention may further include S2201, and S2004 may be replaced with S2004 a:

s2201: the STA receiving the first wake-up message keeps the Wi-Fi of the STA in a sleep state.

S2004 a: and the STA switches the Wi-Fi interface of the STA from the dormant state to the working state at the time indicated by the first indication information.

In the embodiment of the invention, when receiving the first wake-up message, the STA may first keep the Wi-Fi of the STA in a sleep state, and then switch the Wi-Fi interface of the STA from the sleep state to a working state at the time indicated by the first indication information, so as to receive the second wake-up message sent by the AP. In this way, unnecessary waste of power consumption can be avoided.

Further, in a second application scenario of the embodiment of the present invention, the first wake-up message may further carry second indication information, where the second indication information is used to notify the STA: the AP instructs the STA to wake up the STA's Wi-Fi interface using the first wake-up message and the second wake-up message. Prior to S2003, the method of embodiments of the present invention may further include S702. The detailed description of the second indication information and the technical effect of the first wake-up message carrying the second indication information may refer to the related description in the first application scenario, and are not described herein again in the embodiments of the present invention.

Further, in a second application scenario of the embodiment of the present invention, in order to prevent malicious devices from being disguised as an AP, the emulated AP sends the first wake-up message and the second wake-up message to one or more STAs, which causes unnecessary waste of increasing power consumption of the STA that is a wakened device, and the AP and the STA may dynamically negotiate first identification information and second identification information used when the AP wakes up a Wi-Fi interface of the STA next time. After S2008, the method of the embodiment of the present invention may further include S703-S705.

After waking up the Wi-Fi interface of an STA, the AP may perform Wi-Fi data interaction with the STA, and negotiate first identification information and second identification information used when the Wi-Fi interface of the STA is next woken up, that is, the first identification information and the second identification information used when the AP wakes up the Wi-Fi interface of the STA each time may be different. Therefore, the difficulty that the malicious device imitates the AP to maliciously awaken a large number of STAs by using the first awakening message and the second awakening message can be increased, the safety of the awakening process of the STAs by the AP is improved, and unnecessary power consumption caused by the fact that the STAs are maliciously awakened by the malicious device is avoided.

The above description mainly introduces the scheme provided by the embodiment of the present invention from the point of interaction between the AP (i.e., the first wireless device) and the STA (i.e., the second wireless device).
