Description

Method and device for waking up wireless device

The present application claims priority to Chinese Patent Application No. 200910121709.0, entitled "A Method and Apparatus for Wireless Communication," which is incorporated herein by reference. .

Technical field

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

Background technique

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

In order to solve the above problem, the IEEE 802.11 standard organization proposes an ultra-low power wake-up radio/receiver (Wake- that can reduce the average power consumption of Wi-Fi communication technology while realizing on-demand real-time data transmission (Wake- Up Radio/Receiver, WUR) technology. Specifically, the WUR technology refers to adding a WUR module to the device. When no data is received or transmitted, the device's main communication module (for example, a Wi-Fi module) enters deep sleep, and the WUR module is turned on for ultra low power detection. listen. For example, if an access point (AP) is a wake-up device, a station (Station, STA) is a wake-up device, and the WUR module of the STA is in a working state, the WUR message sent by the AP can be monitored, and the STA's main communication module is (such as Wi-Fi module) is in a sleep state. As shown in Figure 1, when an AP has data (such as a Wi-Fi message) to be transmitted to the STA, the AP may first send a WUR message to the WUR module of the STA. After the WUR module of the STA receives the WUR message, if the WUR message is determined. The receiver address matches the address of the WUR of the STA, and the WUR message is correct and true, and a wake-up signal can be sent to the STA's main communication module to wake up the STA's main communication module.

When the AP has data to be transmitted to multiple STAs, that is, the AP needs to wake up the main communication module of multiple STAs, the AP may send a WUR message carrying bitmap information to the WUR module of the multiple STAs. Each bit in the picture information corresponds to one STA; after receiving the WUP carrying the bitmap information, the STA can determine whether the value of the bit corresponding to the STA in the bitmap information is a preset value (eg, Whether the bit corresponding to the STA is set to "1"), if the STA determines that the value of the bit corresponding to the STA is a preset value (such as a bit position "1" corresponding to the STA), a wake-up signal may be sent to The STA's main communication module to wake up the STA's main communication module.

However, in the above awake mode, some malicious devices may be masquerading as APs, and the simulated AP sends a WUR message carrying bitmap information to multiple STAs, and may simply or partially set the bits of the bitmap information. "1", so that the main communication module of a large number of STAs can be easily awake at the same time, which causes a large number of STAs to be maliciously awake by the malicious device, resulting in an increase in the wake-up device STA. Unnecessary waste of power consumption reduces the battery life of the device being woken up. Moreover, after the main communication module of a large number of STAs is awake maliciously, the STAs will compete to send uplink messages on the air interface, causing congestion of the air interface and waste of air interface resources.

Summary of the invention

The present application provides a method and a device for waking up a wireless device, which can improve the security of the STA being awake by the AP, and prevent the STA from being maliciously awake by the malicious device and consuming unnecessary power consumption.

In a first aspect, the present application provides a method for waking up a wireless device, including: transmitting, by a first wireless device, a first wake-up message carrying first identification information to a first communication interface of multiple devices in a broadcast manner or a multicast manner, The first identification information is used to identify at least one of the plurality of devices, including the second wireless device, where the first wake-up message is used to indicate that the first communication interface of the device identified by the first identification information needs to be located a working state to receive a second wake-up message sent by the first wireless device; the first wireless device, after transmitting the first wake-up message, to at least one device of the at least one device including the second wireless device The first communication interface sends a second wake-up message carrying the second identifier information, where the second identifier information is used to identify the device that the first wireless device is to wake up, and the device that the first wireless device is to wake up includes the second wireless device. The second wake-up message is used to indicate that the device identified by the second identifier information wakes up the second communication interface of the device.

The first wireless device (such as an AP) may use the first wake-up message and the second wake-up message to indicate that multiple devices including the second wireless device (such as STA) wake up their second communication interface. In this way, 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, wait for receiving the second wake-up message, and then according to the received second wake-up message. Determining whether to wake up the second communication interface of the second wireless device; instead of directly waking up the second wireless device according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving a wake-up message The second communication interface. Such a double-acknowledgment wake-up mechanism can increase the difficulty of malicious devices waking up a large number of STAs maliciously, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awake by the malicious device to consume unnecessary power consumption.

With reference to the first aspect, in a first possible implementation, the first identifier information includes first bitmap information, where the first bitmap information includes at least two bits, and at least the first bitmap information Two bits are in one-to-one correspondence with each of the at least two groups of the plurality of devices, each of the at least two groups of devices includes at least one device, and the first identification information is used to identify The device in the first bitmap information is a device group corresponding to the first preset value, and the second wireless device is a device corresponding to the first preset value in the first bitmap information. One of a group of devices in a group. The second identifier information includes second bitmap information, where the second bitmap information includes at least two bits, and at least two of the second bitmap information and the first bitmap information have a value of the first value. The devices in the device group corresponding to the preset value bits are in one-to-one correspondence, and the second identifier information is used to identify the device corresponding to the second preset value in the second bitmap information.

Wherein, since at least two bits of the first bitmap information are in one-to-one correspondence with at least two groups of devices, That is, each bit in the first bitmap information may correspond to a group of devices. In this way, the first wireless device (such as an AP) can set the value of one bit in the first bitmap information to indicate that the first communication interface of the device in the device group corresponding to the bit remains in the working state, waiting for receiving. The second wake-up device can reduce the amount of data carried in the first wake-up message without carrying more identification information 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 (such as STA) faster, and the second wireless device can control the first communication earlier. The interface remains active or switched from active to sleep.

Similarly, at least two bits of the second bitmap information are in one-to-one correspondence with devices in a device group, that is, each bit in the second bitmap information may correspond to one device in the device group. In this way, the first wireless device (such as an AP) can indicate that the device corresponding to the bit wakes up its second communication interface (such as a Wi-Fi interface) by setting the value of one bit in the second bitmap information; The second wake-up message needs to carry more identifier information, which can reduce the amount of data carried in the second wake-up message. 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 faster, and the STA can wake up its second communication interface earlier.

The second identification information is used to identify the device corresponding to the second preset value in the third bitmap information.

Wherein, when the first wireless device (such as an AP) wants to wake up multiple devices (such as STAs) in a device group, the first wireless device may send the device to the multiple devices including the device group. The first wake-up message of the group's group address information. Since the group address information of one device group is smaller than the identification information of multiple devices in the device group (such as the device identifier of the STA or the interface identifier of the WUR interface of the STA); therefore, the first wireless device is directed to one device. A plurality of devices in the group send the first wake-up message carrying the group address information of the device group, which not only identifies the device group, but also reduces 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 second wireless device faster, and the second wireless device can control the first communication interface to remain working earlier. The state is switched from the working state to the sleep state. The technical effect of the first wireless device indicating that the second wireless device wakes up its second communication interface by carrying the third bitmap information in the second wake-up message may refer to “the first wireless device passes the second identification information.

Wherein, since at least two bits in the fourth bitmap information are in one-to-one correspondence with a plurality of devices that receive the first wake-up message, the first wireless device (such as an AP) sets each of the fourth bitmap information by setting The value of the bit can indicate that the device corresponding to each bit controls its first communication interface In the working state or the dormant state; without carrying more identification information in the first wake-up message, the amount of data carried in the first wake-up 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 faster, and the second wireless device can be in a working state or a sleep state earlier than the WUR interface. .

detailed description

The terms "first" and "second" in the specification of the present invention and the drawings are used to distinguish The same object, or used to distinguish different treatments of the same object, rather than describing the 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.

A method for waking up a wireless device according to an embodiment of the present invention may be applied to a process in which a first wireless device wakes up one or more devices including a second wireless device.

For example, the first wireless device in the embodiment of the present invention may be an AP, and one or more devices may be one or more STAs (ie, the second wireless device may be a STA).

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

Exemplarily, the one or more STAs may be the mobile phone 202, the camera 203, the computer 204, the display device 205 (such as a television, a computer monitor, etc.), a tablet, a wearable device, a printer, etc. as shown in FIG. . For the convenience of description, only a partial example of the STA is shown in FIG. 2, and the STA described in 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 (ie, AP 201) can communicate with any of the STAs in the BSS.

In the coverage area 211 of the AP 201 as shown in FIG. 2, a basic service area (BSA) may be formed, and the WLAN 200 may be connected to a distributed system (DS) by wire or wirelessly. Multiple APs 201 may form an Extended Service Set (ESS) in this manner. Thus, AP 201 can then communicate with one or more STAs in the ESS.

It should be noted that the network architecture applied by the method of the embodiment of the present invention is not limited to the architecture shown in FIG. 2. For example, the method in the embodiment of the present invention may also be applied to a scenario such as a hotspot AP scenario or a P2P. For example, in the case of the mobile phone 202 and the display 205, the mobile phone 202 can be used in the hotspot mode to serve as an AP, and the display 205 acts as a STA to form a WLAN. The method in the embodiment of the present invention can be applied to the WLAN. Alternatively, the mobile phone 202 acts as a P2P group owner (GO), the display 205 acts as a P2P Cllient, and the mobile phone 202 and the display 105 form a WLAN. The method of the embodiment of the present invention can be applied to the WLAN. Alternatively, the mobile phone 202 functions as a NAN Anchor master, and the display 205 functions as a NAN device. The mobile phone 202 and the display 205 form a WLAN. The method of the embodiment of the present invention can be applied to the WLAN.

In the process in which the AP 201 communicates with one or more STAs through the above WLAN network, the Wi-Fi interface of one or more STAs as shown in FIG. 2 may enter a sleep state to save power. One or more STAs in the WLAN 100 are outside the Wi-Fi interface, and are also equipped with a low power auxiliary wake-up interface (such as a WUR interface as a receiver for waking up the Wi-Fi interface). When the AP has data to transmit data to the STA, the AP may first send a WUR message to the WUR interface of the STA, indicating that the WUR interface wakes up the Wi-Fi interface of the STA to receive data sent by the AP.

The Wi-Fi interface in the embodiment of the present invention may use an antenna to transmit signals respectively with the WUR interface; or, the two may share one antenna for signal transmission, thereby saving the cost of the device.

The WUR message may be a message that can be received and parsed by a WUR interface such as a Wake Up Packet (WUP) or a Wake Up Beacon (also referred to as a WUR Beacon). Alternatively, the WUR message may also be other messages with functionality indicating that the STA wakes up its Wi-Fi interface.

. The mobile phone 102 is taken as an example. The sleep state indicates that the Wi-Fi interface of the mobile phone 102 does not continuously receive the air interface message, and may specifically enter a doze state or a shallow sleep state, that is, Wi- The baseband module of the Fi interface and the Media Access Control (MAC) processor module remain on, the radio frequency (RF) module is turned off, or the deep sleep state (Deep Sleep), that is, the RF module of the Wi-Fi interface. The baseband module and the MAC processor module are all turned off.

A method for waking up a wireless device according to an embodiment of the present invention, a first wireless device (such as an AP) may use two wake-up messages (such as a first wake-up message and a second wake-up message) to instruct a second wireless device (such as a STA) to wake up the first The second communication interface of the second wireless device. That is, 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, wait for receiving the second wake-up message, and then determine according to the received second wake-up message. Whether to wake up the second communication interface of the second wireless device; instead of directly waking up the second wireless device according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving a wake-up message Two communication interfaces. Such a double-acknowledgment wake-up mechanism can increase the difficulty of malicious devices waking up a large number of STAs maliciously, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awake by the malicious device to consume unnecessary power consumption.

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

Illustratively, the embodiment of the present invention is an example in which the AP 301 in the Wi-Fi network 300 shown in FIG. 3 wakes up a scenario of one or more STAs in its coverage, for example, for the wireless device provided by the embodiment of the present invention. The wake-up method is illustrated.

The Wi-Fi network 300 shown in FIG. 3 may include an AP 301 and a plurality of STAs, and the multiple STAs may include 7 STAs such as STA 1, STA 2, and STA 3 as shown in FIG. 3. As shown in Table 1, the device identifiers of seven STAs such as STA 1, STA 2, and STA 3 are STA-1, STA-2, STA-3, ..., STA-7; STA 1, STA 2, and STA 3, respectively. The interface identifiers of the WUR interfaces of the seven STAs are WUR-1, WUR-2, WUR-3, ..., WUR-7; the interface identifiers of the WUR interfaces of the STAs such as STA 1, STA 2, and STA 3 are respectively For Wi-Fi-1, Wi-Fi-2, Wi-Fi-3, ..., Wi-Fi-7.

As shown in FIG. 3, the seven STAs can 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, the device group x includes STA 1, STA 2, and STA 3; the group address information of the device group y is y, and the device group y includes 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 present invention, the group address information of the STA may be allocated to the STA during the process of the Wi-Fi communication 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 the device group when the AP sends data to the STAs in a device group in a multicast manner. Alternatively, the group address information of the STA may be generated by the STA according to the preset group address information generation rule, and the STAs with the same group address information may be regarded as STAs of the same device group. For example, the STA may obtain the group address information of the STA by using a hash algorithm or a preset bit in the identifier information by using a hashing algorithm or a preset information such as a WUR ID. Alternatively, the group address information of the STA may be determined by the STA according to the time information of the BSS where 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, an alphabetic information, etc., which is not limited by the present invention.

After 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 an AID to the STA, the AP may assign an AID to the STA in sequence according to the order in which the STA is associated with the AP. Therefore, the AP 301 may allocate, for each of the foregoing seven STAs, a unique identifier. STA's AID.

As shown in Table 1, when the AP 301 is associated with the STA 1, the Association ID (AID) assigned to the STA 1 is AID-1, and the AID assigned to the STA 2 when the AP 301 establishes association with the STA 2 For AID-2, when the AP 301 establishes association with the STA 3, the AID assigned to the STA 3 is AID-3, ..., and when the AP 301 establishes association with the STA 12, the AID assigned to the STA 7 is AID-7.

Table 1

Here, for convenience of description, only a partial example of the STA is given in FIG. 3, and the present invention is implemented. The STAs described in the examples include but are not limited thereto. For a detailed description of the STA shown in FIG. 3, reference may be made to the description of the STA in FIG. 2 in the embodiment of the present invention, and details are not described herein again.

In the first application scenario of the embodiment of the present invention, the AP 301 may pass one or more to wake up to the AP 301, based on the scenario in which the AP 301 wakes up one or more STAs in the coverage area. The WUR interface of the STA sends a first wakeup message and a second wakeup message to wake up the Wi-Fi interface of the one or more STAs. The first wake-up message and the second wake-up message may be the same or different.

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

S401: The AP sends the first wake-up message to the WUR interface of the multiple STAs in the broadcast mode or the multicast mode. The first wake-up message carries the first identifier information, where the first identifier information is used to identify the multiple STAs to be included. At least one STA, such as the awakened STA, is configured to indicate that the WUR interface of the STA identified by the first identifier information needs to be in an active state to receive a second wake-up message sent by the AP.

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

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

The first awake message carries the first identifier information, where the first identifier information is used to identify the at least one STA that includes the STA to be awake, and the first awake message is used to indicate the first The WUR interface of the STA (that is, the at least one STA) identified by the identifier information needs to be in an active state to receive the second wake-up message sent by the AP 301.

For example, the first wake-up message in the embodiment of the present invention may be a WUR beacon message, or the first wake-up message may be another broadcast message or a multicast message. Alternatively, the first wake-up message may be a wake-up packet message of a broadcast address or a multicast address or group address information of a WUR interface of the STA that the AP is to wake up. Alternatively, the first wakeup message may be a wakeup packet message carrying group address information of the STA that the AP wants to wake up.

As shown in FIG. 5, it 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 identifier information 504 in the WUR message as shown in FIG. 5.

As shown in FIG. 5, the first wake-up message may further include a legacy preamble 501, a WUR reference signal 502, a WUR signaling domain (Signal, SIG) 503, and a Frame Check Sequence (FCS) 505. One or more.

Wherein, the original preamble 501 can be used to announce to the surrounding Wi-Fi devices on the Wi-Fi channel. Use channels to better coexist with Wi-Fi devices. The WUR reference signal 502 can indicate to the STA that the first wake-up message is a WUR message. The WUR SIG may include information such as the first indication information, the second indication information, and the type information indicating the WUR message in the embodiment of the present invention, where the first indication information is used to indicate the time when the AP sends the second wakeup message. The FCS may be used by the STA receiving the WUR message to perform frame check to determine whether the WUR message is correctly received. If the FCS check fails, the STA may discard the WUR message.

S402: The multiple STAs receive the first wake-up message sent by the AP in a broadcast manner or a multicast manner by using the WUR interface of the multiple STAs.

S403: The STA that receives the first wakeup message determines whether the STA is one of the STAs identified by the first identifier information.

Specifically, if the STA determines that the STA is one of the STAs identified by the first identifier information, the method may continue to perform S404; if the STA determines that the STA is not one of the STAs identified by the first identifier information, Continue to execute S409:

S404: The STA keeps the WUR interface of the STA in an active state.

S405: After transmitting the foregoing first waking message, the AP sends a second wake-up message to the WUR interface of the at least one STA that includes the STA to be awake.

The second awake message carries the second identifier information, where the second identifier information is used to identify one or more STAs to be awake by the AP, and the second awake message is used to indicate the STA identified by the second identifier information. Wake up the STA's Wi-Fi interface.

For example, the second wake-up message in the embodiment of the present invention may be a WUR 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 of a broadcast address or a multicast address or group address information of a WUR interface of the STA that the AP is to wake up.

FIG. 6 is a schematic structural diagram of a message of a wake-up message according to an embodiment of the present invention. The second wake-up message provided by the embodiment of the present invention may include at least the second identifier information 604 in the wake-up message as shown in FIG. 6. As shown in FIG. 6, the second wake-up message may further include one or more of the original preamble 601, the WUR reference signal 602, the WUR SIG 603, and the FCS 605. For a specific function 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, and details are not described herein again.

S406: The at least one STA that includes the STA to be awake in the at least one STA receives the second wakeup message through its WUR interface.

S407: The STA that receives the second wakeup message determines whether the STA is one of the STAs identified by the second identifier information.

Specifically, if the STA that receives the second wakeup message determines that the STA is one of the STAs identified by the second identifier information, proceed to S408; if the STA that receives the second wakeup message determines that the STA is not the second One of the STAs identified by the identification information may continue to perform S409 and S410.

S408: The STA wakes up the STA's Wi-Fi interface.

S409: The STA switches the WUR interface of the STA from the working mode to the sleep state.

S409 is optional. The STA may not perform S409 but keep its WUR interface in working state.

S410: The STA keeps the STA's Wi-Fi interface in a sleep state.

In the method for waking up a wireless device, the AP may use the first wakeup message and the second wakeup message to instruct one or more STAs to wake up their Wi-Fi interface. That is, after receiving the first wake-up message, the STA cannot determine whether to wake up the Wi-Fi interface of the STA, wait for receiving the second wake-up message, and then determine whether to wake up the STA according to the received second wake-up message. The Wi-Fi interface directly wakes up the STA's Wi-Fi interface according to the value of the corresponding bit in the bitmap information carried by the wake-up message after receiving a wake-up message. Such a double-acknowledgment wake-up mechanism can increase the difficulty of malicious devices waking up a large number of STAs maliciously, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awake by the malicious device to consume unnecessary power consumption.

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

In the 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 identifier information and the second bitmap information in the second identifier information.

The first identification information includes at least two bits in the first bitmap information, at least two of the first bitmap information and at least one of a plurality of devices (a plurality of STAs receiving the first wake-up message) Each of the two sets of devices (ie, at least two sets of STAs) has a one-to-one correspondence, and each of the at least two sets of devices includes at least one device (ie, at least one STA), and the first identification information is used to identify the first A set of devices (ie, a group of STAs) corresponding to the first preset value of the bitmap information, and a second wireless device (ie, the STA that the AP is to wake up) is a group of devices of at least two groups of devices. One device.

Illustratively, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs within its coverage, the first bitmap information may include three bits "abc" and the three bits "abc" The value of "" (such as a = 1, b = 1, c = 0), the first bit "a" of the three bits "abc" may correspond to device group x, the second bit "b" "Can correspond to device group y, and the third bit "c" can correspond to device group z. The first preset value may be 1 or 0, and the specific value of the first preset value may be determined by 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 the value of the bit corresponding to the device group in which the STA that the AP 301 is to wake up in the first bitmap information to the first preset value. Assuming that the first preset value is 1, the AP 301 is to wake up the STA 1 and the STA 3 in the device group x, and the STA 5 in the device group y. Then, as shown in FIG. 7, the first wake-up message may carry the first The bitmap information "110", that is, a = 1, b = 1, c = 0. At this time, the first identifier 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 the STAs in the device group x (ie, STA 1-STA 3) and the STAs in the device group y. The WUR interfaces of STA 4 and STA 5 are in operation.

In the first implementation manner of the first application scenario, as shown in FIG. 8, S403 in FIG. 4 can be replaced. Change to S403a:

S403: The STA that receives the first wake-up message determines whether the value of the bit corresponding to the group in which the STA is located in the first bitmap information carried in the first wake-up message is a first preset value.

Specifically, if the STA that receives the first wake-up message determines that the value of the bit corresponding to the group in which the STA is located in the first bitmap information carried in the first wake-up message is the first preset value, proceed to S404; If the STA that receives the first wake-up message determines that the value of the bit corresponding to the group in which the STA is located in the first bitmap information that is carried in the first wake-up message is not the first preset value, proceed to S409:

Based on the above example, as shown in FIG. 7, since the first identification information includes the first bitmap information "110", the STA in the device group x (such as STA 1 or STA 2) may determine the first bitmap information "110". If the value of the bit corresponding to the device group x is the first preset value (that is, 1), the WUR interface of the STA may be kept in the working state (such as on), and the STA in the device group y (for example, The STA 4 or the STA 5) can determine that the value of the bit corresponding to the device group y in the first bitmap information "110" is the first preset value (ie, 1), and the WUR interface of the STA can be kept in the working state. That is, the S404 is continued; and the STA in the device group z (such as the STA 6) can 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 the STA can be used. The WUR interface is switched from the working state (such as on) to the sleep state (such as off), that is, the execution continues to S409.

The second identifier information includes second bitmap information, where the second bitmap information includes at least two bits, and at least two bits in the second bitmap information and a bit that is a first preset value The devices in the corresponding device group are in one-to-one correspondence, and the second identifier information is used to identify a device corresponding to the bit with the second preset value.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, since the first bitmap information is "110", the AP 301 can provide the device group x and the device group. The STA in y sends a second wakeup message.

Taking the device group x as an example, the second bitmap information may include three bits "def" and values of the three bits "def" (eg, d=1, e=0, f=1), these three The first bit "d" of the bits "def" may correspond to the STA 1 in the device group x, and the second bit "e" may correspond to the STA 2 in the device group x, the third bit Bit "f" may correspond to STA 3 in 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” (eg, g=0, h=0), and the two bits “ The first bit "g" in gh" may correspond to STA 4 in device group y, and the second bit "h" may correspond to STA 5 in device group y.

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

The AP 301 can set the value of the bit corresponding to the STA that the AP 301 is to wake up in the second bitmap information to the second preset value.

Assuming that the second preset value is 1, the AP 301 is to wake up the STA 1 and the STA 3 in the device group x; then, as shown in FIG. 7, the AP 301 can send the second bitmap information to the STA in the device group x. A second wake-up message of "101" (ie, d = 1, e = 0, f = 1). At this time, the second wake-up message is carried in The second identification information may be used to identify STA 1 and STA 3, and the second wake-up message may be used to instruct STA 1 and STA 3 to wake up their Wi-Fi interface.

Assuming that the second preset value is 1, the AP 301 is to wake up the STA 5 in the device group y; then, as shown in FIG. 7, the AP 301 can transmit the information including the second bitmap information to the STA 5 in the device group y. A second wake-up message of the second identification information of 01" (ie, g=0, h=0). At this time, the second identifier information carried in the second wakeup message may be used to identify the STA 5, and the second wakeup message may be used to instruct the STA 5 to wake up its Wi-Fi interface.

In the first implementation manner of the first application scenario, as shown in FIG. 8, S407 in FIG. 4 may be replaced by S407a:

S407a: The STA that receives the second wakeup message determines 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 wake-up message determines that the value of the bit corresponding to the STA in the second bitmap information is the second preset value, proceed to S408; if the STA that receives the second wake-up message After determining that the value of the bit corresponding to the STA in the second bitmap information is not the second preset value, proceed to S409:

Based on the above example, as shown in FIG. 7, since the second identification information received by the STA in the device group x includes the second bitmap information "101", the STA 1 in the device group x can determine the second bitmap. If the value of the bit corresponding to the STA 1 in the information "101" is the second preset value (ie, 1), the S408 may be continued to wake up the Wi-Fi interface of the STA 3 (ie, the Wi-Fi interface of the STA 3 is in a sleep state). Switching to the working state); the STA 3 in the device group x can determine that the value of the bit corresponding to the STA 3 in the second bitmap information "101" is the second preset value, and can wake up the Wi-Fi interface of the STA 3 That is, the SUR in the device group x can determine that the value of the bit corresponding to the STA 2 in the second bitmap information "101" is not the second preset value, and the WUR interface of the STA can be The working state (such as on) is switched to the sleep state (such as off), that is, the execution continues to S409, and the Wi-Fi interface of the STA is kept in a sleep state (such as 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, indicating that the STA in the device group z is not the STA that the AP 301 is to wake up, so the AP 301 may not be in the device group z. The STA sends a second wakeup message.

In the first implementation manner of the first application scenario, at least two bits of the first bitmap information are in one-to-one correspondence with each of the at least two groups of devices, that is, each bit in the first bitmap information. Can correspond to a group of devices. In this way, by setting the value of one bit in the first bitmap information, the AP can indicate that the WUR interface of the device in the device group corresponding to the bit is in the working state, waiting to receive the second wake-up device; A wake-up message carries more identification information, which 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 faster, and the STA can keep its WUR interface in a working state or enter a sleep state earlier.

Similarly, at least two bits of the second bitmap information are in one-to-one correspondence with devices in a device group, that is, each bit in the second bitmap information may correspond to one device in the device group. In this way, the AP can indicate the bit pair by setting the value of one bit in the second bitmap information. The device should wake up its Wi-Fi interface; instead of carrying more identification information in the second wake-up message, the amount of data carried in the second wake-up 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 faster, and the STA can wake up its Wi-Fi interface earlier.

In the second implementation manner of the first application scenario, the AP may carry the third bitmap in the second wakeup message by carrying the group address information of the device group of the one or more STAs that the AP is to wake up in the first wakeup message. Information to wake up one or more STAs.

The second application scenario is implemented in two ways:

The first identifier information carried in the first waking message described in S401-S403 may include group address information of a device group where the STA that the AP is to wake up. For example, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs within its coverage, it is assumed that the AP 301 is to wake up STA 1 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 the group address information X of the device group x and the group address information Y of the device group y. At this time, the first identifier 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 the STAs in the device group x (ie, STA 1-STA 3) and the STAs in the device group y. The WUR interfaces of STA 4 and STA 5 are in operation. The AP 301 does not need to wake up any STA in the device group z. Therefore, the first identifier information does not include the group address information Z of the device group z.

In the second implementation manner of the first application scenario, as shown in FIG. 10, S403 in FIG. 4 may be replaced by S403b:

S403b: The STA that receives the first wake-up message determines whether the first identifier information carried in the first wake-up message includes group address information of the group in which the STA is located.

Specifically, if the STA that receives the first wake-up message determines that the first identifier information carried in the first wake-up message includes the group address information of the group in which the STA is located, the method may continue to perform S404; if the STA that receives the first wake-up message is received, And determining that the first identifier information carried in the first wake-up message does not include the group address information of the group in which the STA is located, and then proceed to S409:

Based on the above example, as shown in FIG. 9, 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 The STA (such as STA 1 or STA 2) and the STA in the device group y (such as STA 4 or STA 5) can keep the WUR interface of the STA in an active state (such as on), that is, continue to execute S404. As shown in FIG. 9, the STA (such as STA 6) in the device group z can use the WUR interface of the STA because the first identifier information carried in the first wakeup message does not include the group address information Z of the device group z. Switching from the working state (such as on) to the sleep state (such as off), the execution continues to S409.

The second identifier information includes third bitmap information, where the third bitmap information includes at least two bits, and at least two of the third bitmap information are in a device group of the STA that the AP is to wake up. The device has a one-to-one correspondence, that is, the at least two bits in the third bitmap information are in one-to-one correspondence with the devices in the device group corresponding to the group address information included in the first identifier information, and the second identifier information is used to identify the value. The device corresponding to the bit of the second preset value.

Illustratively, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, since the first identification information includes the group address information X and the device of the device group x. The group address information Y of the group y, so the AP 301 can send a second wakeup message to the STAs in the device group x and the device group y.

The method for the AP to wake up the Wi-Fi interface of the STA in the device group by using the second wake-up message carrying the third bitmap information may refer to “the AP indicates by using the second wake-up message carrying the second bitmap information. The method for the STA in the device group to wake up its Wi-Fi interface is not described herein again.

In the second implementation manner of the first application scenario, as shown in FIG. 10, S407 in FIG. 4 may be replaced with S407b:

S407b: The STA that receives the second wake-up message determines 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 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, the process may continue to perform S408; The STA to 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, and may continue to perform S409 and S410.

Based on the above example, as shown in FIG. 9, since the second identification information received by the STA in the device group x includes the third bitmap information "101", the STA 1 in the device group x can determine the third bitmap. If the value of the bit corresponding to the STA 1 in the message "101" is the second preset value (ie, 1), the Wi-Fi interface of the STA 3 can be woken up (ie, the Wi-Fi interface of the STA 3 is switched from the sleep state to the working state. And continuing to perform S408; the STA 3 in the device group x can determine that the value of the bit corresponding to the STA 3 in the third bitmap information "101" is the second preset value, and can wake up the Wi-Fi of the STA 3 The interface continues to execute S408; and the STA 2 in the device group x can determine that the value of the bit corresponding to the STA 2 in the third bitmap information "101" is not the second preset value, and the WUR interface of the STA can be Switching from the working state (such as on) to the sleep state (such as off) continues to execute S409, and keeps the STA's Wi-Fi interface in a sleep state (such as off), that is, executes S410.

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

In the second implementation manner of the first application scenario, when an AP is to wake up multiple STAs in a device group, the AP may send a group address carrying the device group to multiple STAs including the device group. The first wake up message of the message. Since the group address information of one device group is smaller than the identification information of multiple STAs in the device group (such as the device identifier of the STA or the interface identifier of the WUR interface of the STA), the AP is in a device group. The plurality of STAs send the first wake-up message carrying the group address information of the device group, which not only identifies the device group, but also reduces 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 faster, and the STA can keep its WUR interface in a working state or enter a sleep state earlier.

The at least two bits of the third bitmap information are in one-to-one correspondence with the devices in one device group, that is, each bit in the third bitmap information may correspond to one device in the device group. In this way, by setting the value of one bit in the third bitmap information, the AP can indicate that the device corresponding to the bit wakes up its Wi-Fi interface; instead of carrying more identification information in the second wake-up message, The amount of data carried in the second wakeup message is 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 faster, and the STA can wake up its Wi-Fi interface earlier.

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

The third implementation scenario is implemented in three ways:

The fourth bitmap information includes at least two bits, and at least two bits of the fourth bitmap information are in one-to-one correspondence with the plurality of devices, and the first identifier information is used to identify the value as the first preset. The device corresponding to the bit of the value.

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

In the first case of the implementation mode 3, the AP may send the first wake-up message by using a broadcast mode, and the fourth bitmap information carried in the first wake-up message may include each of the device groups shown in FIG. The bits corresponding to the STAs.

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

Assuming that the first preset value is 1, the AP 301 is to wake up the STA 1, the STA 3, and the STA 5. Then, as shown in FIG. 11 or FIG. 12, the first wake-up message may carry the fourth bitmap information “1010100”, that is, a=1, b=0, c=1, d=0, e=1, f=0, g=0. At this time, the first identifier information may be used to identify STA1, STA3, and STA5, and the first wakeup message may be used to indicate that the WUR interfaces of STA1, STA3, and STA5 are in an active state.

In the second case of the implementation mode 3, the AP may send the first wake-up message in a multicast manner, in this case, the first carried in the first wake-up message sent by the AP to the device group x as shown in FIG. The four-bit map information 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 device group. The bit corresponding to each STA in y.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, the AP carries the fourth bit in the first wake-up message sent by the device group x as shown in FIG. The map information may include three bits "abc" and the values of the three bits "abc" (eg, a = 1, b = 0, c = 1), the first of the three bits "abc" Bit "a" may correspond to STA 1 in device group x, second bit "b" may correspond to STA 2 in device group x, and third bit "c" may correspond to device group x STA 3. Assuming that the AP 301 is to wake up STA 1 and STA 3, the AP can transmit the fourth bitmap information "101" to the STAs in the device group x as shown in FIG. 13 or FIG. 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 to the STAs in the device group y and the device group z. At this time, the first identifier information may be used to identify the STA 1 and the STA 3, and the first wake-up message may be used to indicate that the WUR interfaces of the STA 1 and the STA 3 are in an active state.

In the third implementation manner of the first application scenario, as shown in FIG. 15, S403 in FIG. 4 may be replaced by S403c:

S403: The STA that receives the first wake-up message determines 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 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 the first preset value, proceed to S404; The STA to 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, and may continue to execute S409:

Based on the above example, as shown in FIG. 11, since the first identification information includes the fourth bitmap information "1010100", STA 1, STA 3, and STA-5 may determine STA 1 in the fourth bitmap information "1010100", If the value of the bit corresponding to the STA 3 and the STA 5 is a first preset value (ie, 1), the WUR interface of the STA may be kept in an active state (eg, on), and S404 is continued; and STA 2, STA 4, and STA are performed. 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 (ie 1), then the WUR of the STA may be The interface is switched from the working state (such as on) to the sleep state (such as off), that is, the execution continues to S409.

The second identifier information carried in the second waking message includes the “device identifier of the STA to be awake by the AP” or “the interface identifier of the WUR interface of the STA to be awake by the AP”.

For example, the device identifier of an STA may be the MAC address information of the STA, or may be the AID of the STA. Alternatively, the device identifier of an STA may also be used by the STA or the AP to be used to uniquely identify the STA based on the MAC address information of the STA or the AID of the STA.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, as shown in FIG. 11 or FIG. 12, since the fourth bitmap information is “1010100”, the AP 301 can send a second wakeup message to STA 1, STA 3, and STA 5.

The AP may send the second wakeup message to the STA 1, the STA 3, and the STA 5 in a unicast manner or a broadcast manner. When the AP sends the second wakeup message to STA 1, STA 3, and STA 5 in unicast mode, the AP may send the MAC-1 or AID-1 as shown in FIG. Or the second wake-up message of the WUR-1 may send the second wake-up message carrying the MAC-3 or the AID-3 or the WUR-3 as shown in FIG. 11 to the STA 3, and may send the message to the STA 5 as shown in FIG. The second wake-up message carrying MAC-5 or AID-5 or WUR-5. When the AP sends the second wakeup message in the broadcast mode, as shown in FIG. 12, the second wakeup message may carry the MAC-1, the MAC-3, and the MAC-5, or the second wakeup message may carry the AID. -1, AID-3 and AID-5, or the second wakeup message may carry WUR-1, WUR-3 and WUR-5.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, as shown in FIG. 13 or FIG. 14, since the fourth bitmap information is "101", the AP 301 can send a second wake-up message to STA 1 and STA 3.

Similarly, the AP may send a second wake-up message to STA 1 and STA 3 in a unicast manner or a broadcast manner. When the AP sends the second wakeup message to the STA 1 and the STA 3 in the unicast mode, the AP may send the second wakeup message carrying the MAC-1 or AID-1 or WUR-1 as shown in FIG. A second wake-up message carrying MAC-3 or AID-3 or WUR-3 as shown in FIG. 13 may be transmitted to STA 3. When the AP sends the second wakeup message in the broadcast mode, as shown in FIG. 14, the second wakeup message may carry the MAC-1 and the MAC-3, or the second wakeup message may carry the AID-1 and the AID. -3, or the second wakeup message may carry WUR-1 and WUR-3.

In the third implementation manner of the first application scenario, as shown in FIG. 15, S407 in FIG. 4 may be replaced with S407c:

S407c: The STA that receives the second wake-up message determines whether the second identifier 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.

Specifically, if the STA that receives the second wake-up message determines that the second identifier 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, the S408 may continue to be performed; The STA of the second wake-up message determines that the second identifier 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, and may continue to execute S409:

For example, based on the above example, as shown in any of FIGS. 11-14, STA 1 can wake up because the second wakeup message received by STA 1 carries MAC-1/AID-1/WUR-1. The Wi-Fi interface of the STA 1 (ie, the Wi-Fi interface of the STA 1 is switched from the sleep state to the active state), and the execution proceeds to S408.

In the third implementation manner of the first application scenario, since at least two bits in the fourth bitmap information are in one-to-one correspondence with multiple devices that receive the first wake-up message, the AP sets the fourth bitmap information. The value of each bit can be used to indicate that the device corresponding to each bit keeps its WUR interface in a working state or a dormant state; instead of carrying more identification information in the first wake-up message, the first wake-up message can be reduced. The amount of data carried in. 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 faster, and the STA can be in a working state or a sleep state earlier.

In the fourth implementation manner of the first application scenario, the AP may carry the device identifier of multiple STAs that the AP wants to wake up in the first wake-up message or the WUR connection of multiple STAs that the AP wants to wake up. The interface identifier of the port, in the second wake-up message, carries the device identifier of one STA that the AP wants to wake up or the interface identifier of the WUR interface of an STA that the AP wants to wake up to wake up one or more STAs.

The implementation of the first application scenario is four:

The first identifier information carried in the first waking message described in S401-S403 may include: “the device identifier of multiple STAs to be awake by the AP” or “the interface identifier of the WUR interface of multiple STAs to be awake by the AP”, and second The second identifier information carried in the awake message may include the device identifier of one STA that the AP wants to wake up or the interface identifier of the WUR interface of an STA that the AP wants to wake up.

Illustratively, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs within its coverage, it is assumed that the AP 301 is to wake up STA 1, STA 3, and STA 5.

In a case of implementation manner 4, as shown in FIG. 16 or FIG. 17, the AP 301 may send a broadcast manner to multiple STAs including STA 1, STA 3, and STA 5 (including STA 1-STA 7). 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"; STA After receiving the first wake-up message, the STA 3 and the STA 5 may determine that the first identifier information carried in the first wake-up message includes the device identifier of the STA or the interface identifier of the WUR interface of the STA; STA 1, STA 3 and STA 5 can keep their WUR interface in a working state (on); STA 2, STA 4, STA 6 and STA 7 can determine the first wake-up after receiving the first wake-up message. The first identifier information carried in the message does not include the device identifier of the STA or the interface identifier of the WUR interface of the STA; then, STA 2, STA 4, STA 6 and STA 7 can have their WUR interface from the working state (on ) Switch to sleep (off).

In another case of the implementation mode 4, the AP may use the multicast mode to send the device identifier of the STA that the AP is to wake up or the interface identifier of the WUR interface to all the STAs in the device group of the STA that the AP is to wake up. First wake up message.

For example, as shown in FIG. 18 or FIG. 19, the AP 301 can transmit to all STAs (STA 1-STA-3) in the device group x where STA 1 and STA 3 are located carrying "MAC-1 and MAC-3" or " The first wake-up message of AID-1 and AID-3" or "WUR-1 and WUR-3" is sent to all STAs (STA 4-STA-5) in the device group y where STA 5 is located carrying "MAC-5" "Or the first wake-up message of "AID-5" or "WUR-5". After receiving the first wake-up message, the STA 1, the STA 3, and the STA 5 may determine that the first identifier information carried in the first wake-up message includes the device identifier of the STA or the interface identifier of the WUR interface of the STA; STA 1, STA 3 and STA 5 can keep their WUR interface in a working state (on); after receiving the first wake-up message, STA 2 and STA 4 can determine the first carried in the first wake-up message. The device identifier of the STA or the interface identifier of the WUR interface of the STA is not included in the identifier information; then, the STA 2 and the STA 4 can switch their WUR interface from the working state (on) to the sleep state (off).

In a case of implementation manner 4, as shown in FIG. 16 or FIG. 18, after transmitting the first wake-up message, the AP 301 may send the bearer to the STA 1, the STA 3, and the STA 5 in a multicast manner. 1. MAC-3 and MAC-5" or "AID-1, AID-3 and AID-5" or "WUR-1, WUR-3 and WUR-5" second wake-up messages; STA 1, STA 3 and STA 5 receives the second After the waking message is received, the second identifier information carried in the second waking message includes the device identifier of the STA or the interface identifier of the WUR interface of the STA. Then, STA 1, STA 3, and STA 5 can wake up the message. The Wi-Fi interface has its Wi-Fi interface in operation (on).

In another case of implementation manner 4, as shown in FIG. 17 or FIG. 19, the AP 301 may send the MAC-1 or AID-1 to the STA 1 in a unicast manner after transmitting the first wake-up message. Or the second wake-up message of the WUR-1"; after receiving the second wake-up message, the STA 1 may determine that the second identifier information carried in the second wake-up message includes the device identifier of the STA or the WUR of the STA The interface identifier of the interface; then, STA 1 can wake up its Wi-Fi interface and put its Wi-Fi interface into operation (on). After transmitting 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; the STA 3 receives the second wake-up. After the message, the second identifier 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. Then, the STA 3 can wake up the Wi-Fi interface, so that the STA 3 can wake up the Wi-Fi interface. The Wi-Fi interface is working (on). After transmitting the first wake-up message, the AP 301 may send a second wake-up message carrying "MAC-5 or AID-5 or WUR-5" to the STA 5 in a unicast manner; the STA 5 receives the second wake-up. After the message, the second identifier 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. Then, the STA 5 can wake up the Wi-Fi interface, so that the STA 5 can wake up the Wi-Fi interface. The Wi-Fi interface is working (on).

Wherein, since the AP does not continue to send the second wakeup message to STA2, STA4, STA6, and STA 7, STA2, STA4, STA6, and STA7 do not need to wake up their Wi-Fi interface.

The AP may not send the second wakeup message immediately after sending the first wakeup message. Therefore, after the STA that wakes up the AP receives the first wakeup message, even if it is always in the working state, the first indication information is It is also impossible to receive the second wake-up message before the indicated time, which may cause unnecessary waste of STA power consumption. In order to further reduce the unnecessary waste of the power consumption of the STA, the first waking message may further carry the first indication information, where the first indication information is used to indicate the time when the AP sends the second waking message. For example, the first indication information may be included in the WUR SIG 503 as shown in FIG. Before S403, the method of the embodiment of the present invention may further include S701, and S404 may be replaced by S404a:

S701: The STA that receives the first wake-up message switches the WUR interface of the STA from the working state to the sleep state.

S404a: The STA controls the WUR interface of the STA to switch from the sleep state to the working 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 sleep state, and then, at the time indicated by the first indication information, The sleep state is switched to the working state 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 waking message may further carry the second indication information, where the second indication information is used to notify the STA that the AP uses the first wakeup message and the second wakeup message to indicate that the STA wakes up. The STA's Wi-Fi interface. Before S403, the method of the embodiment of the present invention may further include S702, and S404 may be replaced by S404a:

S702: The STA that receives the first wakeup message determines that the first wakeup message further carries the second indication information.

For example, the second indication information may be included in the WUR SIG 503 as shown in FIG. The STA that receives 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 as shown in FIG. 5 is 1. It can be determined that the AP will use the first wake-up message and the second wake-up message to instruct the STA to wake up the Wi-Fi interface of the STA, and the STA can 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 may carry the third indication information, where the third indication information may be used to notify the STA that the AP uses the first wake-up message to instruct the STA to wake up the Wi-Fi of the STA. interface. When the first wake-up message carries the third identifier information, the STA that receives the first wake-up message may directly wake up the Wi-Fi interface of the STA without waiting to receive the second wake-up message.

For example, the third indication information may be included in the WUR SIG 503 as shown in FIG. 5, and the STA that receives the first wake-up message may determine the value of the preset bit in the WUR SIG 503 as shown in FIG. 5. If it is determined that the first wake-up message further carries the third indication information, it may be determined that the AP will use the first wake-up message to instruct the STA to wake up the STA's Wi-Fi interface, and the STA may directly wake up the STA's Wi-Fi. Interface without waiting to receive a second wakeup message. In the embodiment of the present invention, the AP may notify the AP that the STA wakes up the mode of the Wi-Fi interface of the STA by using the foregoing second indication information and the third indication information, that is, “the AP indicates the STA by using the first wakeup message and the second wakeup message. Wake up the STA's Wi-Fi interface" or "The AP uses the first wake-up message to instruct the STA to wake up the STA's Wi-Fi interface", so that the STA receives the first wake-up carrying the second indication information or the third indication information After the message, the mode of the AP waking up the STA may be determined, and when the “AP uses the first wake-up message to instruct the STA to wake up the Wi-Fi interface of the STA”, the second wake-up message is not sent to the STA, and the STA receives the message. After the first wake-up message, since the second wake-up message is always waiting to be received, the Wi-Fi interface cannot be woken up in time, causing the Wi-Fi data transmission between the AP and the STA to fail.

Further, in order to prevent the malicious device from masquerading as an AP, the imitation AP sends the first wake-up message and the second wake-up message to one or more STAs, causing unnecessary waste of increasing power consumption of the wake-up device STA, AP and STA. The first identification information and the second identification information used by the AP to wake up the Wi-Fi interface of the STA next time can be dynamically negotiated. After S408, the method of the embodiment of the present invention may further include S703-S705:

S703: After waking up the Wi-Fi interface, the STA sends a wakeup response message to the AP, where the wakeup response message is used to indicate that the STA's Wi-Fi interface is in an active state.

The working state of the STA's Wi-Fi interface may mean that the STA's Wi-Fi interface can perform Wi-Fi data interaction with the AP. For example, the STA may send a PS-Poll frame to the AP through the STA's Wi-Fi interface, or the STA may send a PS-Poll frame to the AP through the STA's Wi-Fi interface after a period of sleep. Exemplarily, the above wakeup response message may be a PS-Poll frame.

S704: The AP receives the wakeup response message sent by the STA by using the STA's Wi-Fi interface.

After receiving the wakeup response message sent by the STA through the STA's Wi-Fi interface, the AP can determine that the STA's Wi-Fi interface is working, that is, the STA's Wi-Fi interface can be The AP performs Wi-Fi data interaction.

S705: The AP negotiates, with the STA, the first identifier information and the second identifier information that are used when the Wi-Fi interface of the STA is awake.

The AP may perform Wi-Fi data interaction with the STA to negotiate the first identification information and the second identification information used when the Wi-Fi interface of the STA is awake for the next time.

In the embodiment of the present invention, after waking up the Wi-Fi interface of an STA, the AP may perform Wi-Fi data exchange with the STA, and negotiate the first identification information and the first used when waking up the Wi-Fi interface of the STA. The second identification information, that is, the first identification information and the second identification information used by the AP each time the WLAN device wakes up the Wi-Fi interface of the STA may be different. In this way, it is possible to increase the difficulty that the malicious device mimics the AP to use the first wake-up message and the second wake-up message to maliciously wake up a large number of STAs, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awakened by the malicious device to consume unnecessary work. Consumption.

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 transmitted through the WUR interface), and the transmission rate of the WUR message may be lower. As a result, the WUR cannot receive the WUR message in time, and thus cannot wake up its Wi-Fi interface in time, affecting the data transmission on the Wi-Fi interface to be woken up.

In the second application scenario of the embodiment of the present invention, the AP may send the first wake-up message to the WUR interface of one or more STAs to be awake by the AP, in order to improve the efficiency of the AP instructing the STA to wake up the Wi-Fi interface. Instructing the STA to wake up its Wi-Fi interface; then, the AP sends a second wake-up message to the Wi-Fi interface of the one or more STAs that the AP is to wake up, so that the STA that receives the second wake-up message according to the indication of the second wake-up message Determine if your Wi-Fi interface is working. 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 the first wake-up message to the WUR interface of the multiple STAs in the broadcast mode or the multicast mode. The first wake-up message carries the first identifier information, where the first identifier information is used to identify the multiple STAs to be included. At least one STA, such as the awakened STA, the first wake-up message is used to indicate that the WUR interface of the STA identified by the first identifier information needs to wake up the Wi-Fi interface of the STA to receive the second wake-up message sent by the AP. .

In the second application scenario of the embodiment of the present invention, the specific manner for the AP to send the first wake-up message to the WUR interface of the multiple STAs and the specific content of the first identifier information may refer to the related description in the first aspect of the embodiment of the present invention. The embodiments of the present invention are not described herein again.

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

S2002: The multiple STAs receive the AP by using the WUR interface of the multiple STAs in a broadcast manner. Or the first wake-up message sent by multicast.

S2003: The STA that receives the first wakeup message determines whether the STA is one of the STAs identified by the first identifier information.

Specifically, if the STA determines that the STA is one of the STAs identified by the first identifier information, the S2004 may continue to be performed; if the STA determines that the STA is not one of the STAs identified by the first identifier information, the STA The WUR interface of the STA can be switched from the working state to the sleep state, and the Wi-Fi interface of the STA is kept in a dormant state.

S2004: The STA wakes up the STA's Wi-Fi interface.

S2005: After transmitting the foregoing first wake-up message, the AP sends a second wake-up message to the WUR interface of the at least one STA that includes the STA to be woken up.

In the second application scenario of the second embodiment of the present invention, the specific manner of the second wake-up message sent by the AP to the WUR interface of the at least one STA, including the STA to be awake, and the specific content of the second identifier information may be referred to. The related description in the first application scenario of the embodiment of the present invention is not described herein again.

The second wake-up message in the first application scenario is used to indicate that the STA identified by the second identifier information wakes up the Wi-Fi interface of the STA, and the second wake-up message in the second application scenario is used. The Wi-Fi interface indicating the device identified by the second identification information is in an active state.

For example, the second wake-up message in the second application scenario may be a WUR Beacon message or a TIM frame carrying a Data Indication Map (TIM) element. Alternatively, the second wake-up message in the second application scenario may be a specially defined action frame, and the action frame may carry bitmap information (such as second bitmap information).

FIG. 21 is a schematic structural diagram of a message 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 2104. A TIM element 2105 is included in the frame body 2103, and the TIM element 2105 includes at least second identification information 2108. Of course, the TIM element 2105 can also include a TIM element identification 2106 and a length 2107.

For example, the second identifier information 2108 shown in FIG. 21 may be the second bitmap information in the embodiment of the present invention, or the second identifier information 2108 may include the device identifier of the STA that the AP is to wake up or the AP needs to wake up. The interface identifier of the STA's Wi-Fi interface.

S2006: At least one STA of the at least one STA that includes the STA to be awake receives the second wakeup message through its Wi-Fi interface.

S2007: The STA that receives the second wakeup message determines whether the STA is one of the STAs identified by the second identifier information.

Specifically, if the STA that receives the second wakeup message determines that the STA is one of the STAs identified by the second identifier information, the S2008 may continue to be performed; if the STA that receives the second wakeup message determines that the STA is not the second One STA of the STA identified by the identification information may continue to execute S2009.

S2008: The STA keeps the STA's Wi-Fi interface in an active state.

S2009: The STA switches the STA's Wi-Fi interface from the working mode to the sleep state.

In the method for waking up a wireless device, the AP may use the first wakeup message and the second wakeup message to instruct one or more STAs to wake up their Wi-Fi interface. Specifically, the STA that receives the first wake-up message may wake up its Wi-Fi interface according to the indication of the first wake-up message to wait to receive the second wake-up message or keep its Wi-Fi interface in a sleep state; however, wake up Wi- The Wi-Fi interface of the STA of the Fi interface is not always in working state, but needs to determine whether the STA's Wi-Fi interface is in the working state after receiving the second wake-up message; instead of receiving one After the wake-up message, the Wi-Fi interface of the STA is woken up according to the value of the corresponding bit in the bitmap information carried in the wake-up message, and the Wi-Fi interface of the STA is kept in the working state. Such a double-acknowledgment wake-up mechanism can increase the difficulty of malicious devices waking up a large number of STAs maliciously, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awake by the malicious device to consume unnecessary power consumption.

In the 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 content in the first wakeup message and the second wakeup message.

In the 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 identifier information and the second bitmap information in the second identifier information. For the specific content of the first bitmap information and the second bitmap information in the second application scenario, reference may be made to the related description in the implementation manner of the application scenario, which is not described herein again.

In the first implementation manner of the second application scenario, as shown in FIG. 22, S2003 in FIG. 20 may be replaced with S403a. After performing S403a, if the STA that receives the first wake-up message determines that the value of the bit corresponding to the group in which the STA is located in the first bitmap information carried in the first wake-up message is the first preset value, the S2004 may be continued. If the STA that receives the first wake-up message determines that the value of the bit corresponding to the group in which the STA is located in the first bitmap information carried in the first wake-up message is not the first preset value, the STA may The WUR interface is switched from the working state to the sleep state, and the Wi-Fi interface of the STA is kept in a sleep state. Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, assuming that the first preset value is 1, the AP 301 wakes up STA 1 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 in the device group x (such as STA 1 or STA 2) and the device group y The STA in the STA (such as STA 4 or STA 5) may determine that the value of the bit corresponding to the device group (such as device group x or device group y) in the first bitmap information "110" is the first preset value ( That is, 1), the Wi-Fi interface of the STA can be woken up, and the Wi-Fi interface is in an active state (such as on) to continue to execute S2004; and the STA in the device group z (such as STA 6) can determine the first In the bitmap information "110", the value of the bit corresponding to the device group z is not the first preset value, and the WUR interface of the STA may be switched from the working state (such as on) to the sleep state (such as off), and the AT is maintained. The Wi-Fi interface is in a sleep state. In the first implementation manner of the second application scenario, as shown in FIG. 22, S2007 in FIG. 20 may be replaced with S407a. After performing S407a, 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, the S2008 may continue to be performed; if the second wakeup message is received The STA determines that the value of the bit corresponding to the STA in the second bitmap information is not the second preset value, and may continue to execute S2009.

Since the first bitmap information is "110", the AP 301 can send a second wakeup 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 should wake up STA 1 and STA 3 in the device group x; then, as shown in FIG. 23, the AP 301 can send the STA in the device group x. A second wake-up message carrying the second bitmap information "101". At this time, the second identifier information carried in the second wake-up message may be used to identify the STA 1 and the STA 3, and the second wake-up message may be used to indicate that the Wi-Fi interfaces of the STA 1 and the STA 3 are in an active state. Since the second identification information received by the STA in the device group x includes the second bitmap information "101"; then the STA 1 and the STA 3 in the device group x can determine the STA 1 in the second bitmap information "101". If the value of the corresponding bit is the second preset value (ie, 1), the S2008 may continue to be executed, and the Wi-Fi interface is kept in the working state; and the STA 2 in the device group x may determine the second bitmap information. The value of the bit corresponding to the STA 2 in 101" is not the second preset value, and the Wi-Fi of the STA may be switched from the working state (such as on) to the sleep state (such as off), that is, the S2009 is continued.

In the second implementation scenario of the second application scenario, the AP may carry the third bitmap in the second wakeup message by carrying the group address information of the device group of the one or more STAs that the AP is to wake up in the first wakeup message. Information to wake up one or more STAs. For the specific content 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, reference may be made to the related description in the second implementation scenario of the first application scenario, and details are not described herein again.

In the second implementation manner of the second application scenario, S2003 in FIG. 20 may be replaced with S403b. After performing S403b, if the STA that receives the first wake-up message determines that the first identifier information carried in the first wake-up message includes the group address information of the group in which the STA is located, the S2004 may continue to be performed; if the first wake-up message is received, The STA determines that the first identifier information carried in the first wake-up message does not include the group address information of the group in which the STA is located, and the STA can keep the Wi-Fi interface of the STA in a dormant state. Optionally, the STA may also switch the WUR interface of the STA from the working state to the sleep state.

Illustratively, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs within its coverage, it is assumed that the AP 301 is to wake up STA 1 and STA 3 in the device group x, and STAs in the device group y 5, then, as shown in FIG. 24, 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 (such as STA 1 or STA 2) and STAs in device group y (such as STA 4 or STA 5) can wake up the STA's Wi-Fi interface and put its Wi-Fi interface into operation (such as on), that is, continue Execute S2004. As shown in FIG. 24, since the first identifier information carried in the first wakeup message does not include the group address information Z of the device group z, the STA in the device group z (such as the STA 6) can maintain the Wi- of the STA. The Fi interface is in a sleep state (such as off), and the WUR interface of the STA is switched from the working state to the sleep state.

In the second implementation manner of the second application scenario, S2007 in FIG. 20 may be replaced with S407b. 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 third bitmap information carried in the second wake-up message is the second preset value, S2008 may continue to be performed; If the STA that receives the second wakeup message determines the third carried in the second wakeup message The value of the bit corresponding to the STA in the bitmap information is not the second preset value, and S2009 can be continued.

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 can send the first to the STAs in the device group x and the device group y. Second wake up message.

Taking the device group x as an example, assuming that the second preset value is 1, the AP 301 should wake up STA 1 and STA 3 in the device group x; then, as shown in FIG. 23, the AP 301 can send the STA in the device group x. The second wake-up message carrying the third bitmap information "101". At this time, the second identifier information carried in the second wake-up message may be used to identify the STA 1 and the STA 3, and the second wake-up message may be used to indicate that the Wi-Fi interfaces of the STA 1 and the STA 3 are in an active state. Since the second identification information received by the STA in the device group x includes the third bitmap information "101"; then the STA 1 and the STA 3 in the device group x can determine the STA 1 in the third bitmap information "101". If the value of the corresponding bit is the second preset value (ie, 1), the S2008 may continue to be executed to keep the Wi-Fi interface in the working state; and the STA 2 in the device group x may determine the third bitmap information. The value of the bit corresponding to the STA 2 in 101" is not the second preset value, and the Wi-Fi of the STA may be switched from the working state (such as on) to the sleep state (such as off), that is, the S2009 is continued.

In the third implementation manner of the second application scenario, the AP may carry the fourth bitmap information in the first wakeup message, and carry the “device identifier of the STA to be awake by the AP” or “AP wake up” in the second wakeup message. The interface identifier of the WUR interface of the STA" to wake up one or more STAs. For the specific content of the device identifier and the fourth bitmap information of the STA in the second application scenario, reference may be made to the related description in the third implementation manner of the first application scenario, which is not repeatedly described herein.

In the third implementation manner of the second application scenario, S403 in FIG. 20 may be replaced by S403c. After performing S403c, 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, the S2004 may continue to be performed; 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 not the first preset value, the WUR interface of the STA is switched from the working state. Go to sleep and keep the STA's Wi-Fi interface in a sleep state.

In the first case of the implementation mode 3, the AP may send the first wake-up message by using a broadcast mode, and the fourth bitmap information carried in the first wake-up message may include each of the device groups shown in FIG. The bits corresponding to the STAs. As shown in FIG. 25 or FIG. 25, the first wake-up message may carry the fourth bitmap information "1010100". At this time, the first identification information may be used to identify STA 1, STA 3, and STA 5. The first wake-up message may be used to instruct STA 1, STA 3, and STA 5 to wake up their Wi-Fi interface to make Wi- The Fi interface is working.

In the second case of the implementation mode 3, the AP may send the first wake-up message in the multicast mode. In this case, the fourth bitmap information carried in the first wake-up message sent by the AP to the device group x may be The fourth bitmap information carried in the first wake-up message sent by the AP to the device group y may include the bit corresponding to each STA in the device group y, including the bit corresponding to each STA in the device group x. Taking the device group x as an example, if the AP 301 is to wake up the device group x terminals STA 1 and STA 3, then, as shown in FIG. 27 or FIG. 28, the AP may send the fourth bit to the STA in the device group x. The first wake-up message of the figure information "101". 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 STA 1 and the STA 3, and the first wake-up message may be used to instruct the STA 1 and the STA 3 to wake up their Wi-Fi interface and make the Wi-Fi interface in an active state.

In the third implementation manner of the second application scenario, S2007 in FIG. 20 may be replaced with S407c. After performing S407c, if the STA that receives the second wakeup message determines that the second identifier information carried in the second wakeup message includes the device identifier of the STA or the interface identifier of the WUR interface of the STA, the S2008 may continue to be performed; The STA that receives the second wake-up message determines that the second identifier 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, and may continue to perform S2009.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, as shown in FIG. 25 or FIG. 25, since the fourth bitmap information is “1010100”, the AP 301 can send a second wakeup message to STA 1, STA 3, and STA 5. When the AP sends the second wake-up message to the STA 1, the STA 3, and the STA 5 in a unicast manner, the AP may send the STA 1 carrying the MAC-1 or AID-1 or WUR-1 as shown in FIG. The second wake-up message may send a second wake-up message carrying MAC-3 or AID-3 or WUR-3 as shown in FIG. 25 to the STA 3, and may send the MAC-5 carried to the STA 5 as shown in FIG. 25. Or the second wake-up message of AID-5 or WUR-5. When the AP sends the second wakeup message in the broadcast mode, as shown in FIG. 25, the second wakeup message may carry the MAC-1, the MAC-3, and the MAC-5, or the second wakeup message may carry the AID. -1, AID-3 and AID-5, or the second wakeup message may carry WUR-1, WUR-3 and WUR-5.

Exemplarily, based on the scenario in which the AP 301 as shown in FIG. 3 wakes up one or more STAs in its coverage, as shown in FIG. 27 or FIG. 28, since the fourth bitmap information is “101”, the AP 301 can send a second wake-up message to STA 1 and STA 3. The AP may send a second wake-up message to STA 1 and STA 3 in a unicast manner or a broadcast manner. When the AP sends the second wakeup message to STA 1 and STA 3 in unicast mode, the AP may send the second wakeup message carrying MAC-1 or AID-1 or WUR-1 as shown in FIG. A second wake-up message carrying MAC-3 or AID-3 or WUR-3 as shown in FIG. 27 may be transmitted to STA 3. When the AP sends the second wake-up message in the broadcast mode, as shown in FIG. 28, the second wake-up message may carry the MAC-1 and the MAC-3, or the second wake-up message may carry the AID-1 and the AID. -3, or the second wakeup message may carry WUR-1 and WUR-3. For example, based on the above example, as shown in any of the figures in FIG. 25 to FIG. 28, taking STA 1 as an example, the second wake-up message received by STA 1 carries MAC-1/AID-1/WUR-1. Therefore, STA 1 can wake up the STA 1 Wi-Fi interface (ie, switch the STA 1 Wi-Fi interface from the sleep state to the active state), and continue to execute S2008.

In the fourth implementation manner of the second application scenario, the AP may carry, in the first wake-up message, the “device identifier of multiple STAs to be awake by the AP” or the interface identifier of the WUR interface of multiple STAs that the AP is to wake up. In the second wake-up message, the device identifier of one STA that the AP wants to wake up or the interface identifier of the WUR interface of an STA that the AP wants to wake up is used to wake up one or more STA.

In a case of implementation manner 4, based on the scenario shown in FIG. 3, it is assumed that the AP 301 is to wake up STA 1, STA 3, and STA 5. As shown in FIG. 29 or FIG. 30, the AP 301 may adopt a broadcast manner to include Multiple STAs (including STA 1-STA 7) including STA 1, STA 3, and STA 5 carry "MAC-1, MAC-3, and MAC-5" or "AID-1, AID-3, and AID- The first wake-up message of 5" or "WUR-1, WUR-3, and WUR-5"; after receiving the first wake-up message, STA 1, STA 3, and STA 5 may determine that the first wake-up message is carried. The first identifier information includes the device identifier of the STA or the interface identifier of the WUR interface of the STA. Then, unlike FIG. 16 or FIG. 17, STA 1, STA 3, and STA 5 can wake up their Wi-Fi interface and put their Wi-Fi interface into operation (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 identifier information carried in the first wake-up message does not include the device identifier of the STA or the WUR interface of the STA. Interface identifier.

In another case of the implementation mode 4, the AP may use the multicast mode to send the device identifier of the STA that the AP is to wake up or the interface identifier of the WUR interface to all the STAs in the device group of the STA that the AP is to wake up. First wake up message. Based on the scenario shown in FIG. 3, assuming that the AP 301 is to wake up STA 1, STA 3, and STA 5, as shown in FIG. 31 or FIG. 32, the AP 301 can go to all STAs in the device group x where STA 1 and STA 3 are located ( STA 1-STA-3) sends a first wake-up message carrying "MAC-1 and MAC-3" or "AID-1 and AID-3" or "WUR-1 and WUR-3" to the device where STA 5 is located All STAs (STA 4-STA-5) within group y send a first wake-up message carrying "MAC-5" or "AID-5" or "WUR-5". Different from FIG. 18 or FIG. 19, the STA 1, the STA 3, and the STA 5 receive the first wake-up message, and determine that the first identifier information carried in the first wake-up message includes the device identifier of the STA or the STA. After the interface of the WUR interface is identified, you can wake up its Wi-Fi interface and make its Wi-Fi interface working (on).

In a case of implementation manner 4, as shown in FIG. 29 or FIG. 31, after transmitting the first wake-up message, the AP 301 may send the bearer to the STA 1, the STA 3, and the STA 5 in a multicast manner. 1. MAC-3 and MAC-5" or "AID-1, AID-3 and AID-5" or "WUR-1, WUR-3 and WUR-5" second wake-up messages; and Figure 29 or Figure 31 The STA 1 , the STA 3 , and the STA 5 receive the second wake-up message, and determine that the second identifier information carried in the second wake-up message includes the device identifier of the STA or the interface of the WUR interface of the STA. After the identification, the Wi-Fi interface can be kept working (on).

In another case of implementation manner 4, as shown in FIG. 30 or FIG. 32, the AP 301 may send the MAC-1 or AID-1 to the STA 1 in a unicast manner after transmitting the first wake-up message. Or the second wake-up message of the WUR-1"; after receiving the second wake-up message, the STA 1 may determine that the second identifier information carried in the second wake-up message includes the device identifier of the STA or the WUR of the STA The interface identifier of the interface; then, STA 1 can keep its Wi-Fi interface working (on). After transmitting 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; the STA 3 receives the second wake-up. After the message, the second identifier 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 3 can keep its Wi-Fi interface active (on).

Wherein, since the AP does not continue to send the second wakeup message to STA2, STA4, STA6, and STA 7, STA2, STA4, STA6, and STA7 can keep their Wi-Fi interface in a sleep state. Further, in the second application scenario of the embodiment of the present invention, in order to further reduce the unnecessary waste of the power consumption of the STA, the first wake-up message may further carry the first indication information, where the first indication information is used to indicate Receiving the time when the AP sends the second wakeup message. For example, the first indication information may be included in the WUR SIG 503 as shown in FIG. Prior to S2003, the method of the embodiment of the present invention may further include S2201, and S2004 may be replaced by S2004a:

S2201: The STA that receives the first wake-up message keeps the STA's Wi-Fi in a sleep state.

S2004a: The STA switches the STA's Wi-Fi interface from the sleep state to the working 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 keep the Wi-Fi of the STA in a dormant state, and then, at the time indicated by the first indication information, the STA's Wi-Fi interface is The sleep state is switched to the working state to receive the second wake-up message sent by the AP. In this way, unnecessary waste of power consumption can be avoided.

Further, in the second application scenario of the embodiment of the present invention, the first wake-up message may further include second indication information, where the second indication information is used to notify the STA that the AP uses the first wake-up message and the second The wakeup message instructs the STA to wake up the STA's Wi-Fi interface. Prior to S2003, the method of the embodiment of the present invention may further include S702. For a detailed description of the second indication information and the technical effect of the second indication information in the first awake message, reference may be made to the related description in the first application scenario, and details are not described herein again.

Further, in the second application scenario of the embodiment of the present invention, in order to prevent the malicious device from masquerading as an AP, the simulated AP sends the first wake-up message and the second wake-up message to one or more STAs, thereby increasing the wake-up device. The unnecessary waste of the power consumption of the STA, the AP and the STA can dynamically negotiate the first identification information and the second identification information used by the AP to wake up the 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 the AP wakes up the Wi-Fi interface of the STA, the AP can perform Wi-Fi data exchange with the STA, and negotiate the first identifier information and the second identifier information used when the Wi-Fi interface of the STA is awake for the next time. That is, the first identification information and the second identification information used by the AP each time the wake-up of the STA's Wi-Fi interface may be different. In this way, it is possible to increase the difficulty that the malicious device mimics the AP to use the first wake-up message and the second wake-up message to maliciously wake up a large number of STAs, improve the security of the STA being awakened by the AP, and prevent the STA from being maliciously awakened by the malicious device to consume unnecessary work.
