[0002] In order to improve the throughput of the wireless link in a wireless terminal and reduce network latency, dual-band Wi-Fi acceleration is usually adopted to enable the terminal to connect to two APs simultaneously. After the wireless terminal is connected to the router in the local area network, the wireless terminal and the router do not need to perform data interaction for most of the time. During the time when there is no data interaction between the wireless terminal and the router, the router will periodically send beacon frames (Beacon) to the two wireless links of the wireless terminal respectively, and the Beacon is used to indicate whether there is downlink data that needs to be sent to the wireless terminal by the router. Therefore, in order to save power consumption, the wireless links of the wireless terminal are always in the sleep state, and only when a Beacon indicating that there is downlink data that needs to be sent to the wireless terminal by the router is detected, the wireless terminal will wake up the wireless link corresponding to the Beacon to perform data interaction with the router based on the wireless link.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0045] As used herein, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, both A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0046] In the embodiments of this application, the electronic device includes a terminal and a router. Please refer to Figure 1 , which shows a block diagram of the structure of a wireless terminal 100 provided by an exemplary embodiment of this application. In some embodiments, the wireless terminal 100 is a terminal such as a smart phone, a tablet computer, a wearable device, etc. that can access a wireless local area network as a wireless station. The terminal 100 in this application includes at least one or more of the following components: a processor 110, a memory 120, and at least two wireless links 130.

[0047] In some embodiments, the processor 110 includes one or more processing cores. The processor 110 connects various parts within the entire terminal 100 using various interfaces and lines, and by running or executing the program code stored in the memory 120 and calling the data stored in the memory 120, it executes various functions of the terminal 100 and processes data. In some embodiments, the processor 110 is implemented in at least one of the following hardware forms: Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 can integrate one or a combination of several of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Neural-network Processing Unit (NPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, application programs, etc.; the GPU is responsible for rendering and drawing the content to be displayed on the display screen; the NPU is used to implement Artificial Intelligence (AI) functions; the modem is used to process wireless communications. It can be understood that the above-mentioned modem can also not be integrated into the processor 110 and can be implemented separately by a single chip.

[0048] In some embodiments, the processor 110 is used to control the operating conditions of at least two wireless links 130. Correspondingly, the processor 110 is a processor integrated with a Wireless Fidelity (Wi-Fi) chip. Among them, the Wi-Fi chip is a chip with dual Wi-Fi processing capabilities. For example, the Wi-Fi chip is a Dual Band Dual Concurrent (DBDC) chip, or a Dual Band Simultaneous (DBS) chip, etc.

[0049] In some embodiments, the memory 120 includes a Random Access Memory (RAM). In some embodiments, the memory 120 includes a Read-Only Memory (ROM). In some embodiments, the memory 120 includes a non-transitory computer-readable storage medium. The memory 120 can be used to store program code. The memory 120 may include a program storage area and a data storage area. Among them, the program storage area can store instructions for implementing the operating system, instructions for at least one function (such as touch function, sound playback function, image playback function, etc.), instructions for implementing the following various method embodiments, etc.; the data storage area can store data created according to the use of the terminal 100 (such as audio data, phone book), etc.

[0050] In some embodiments, the memory 120 stores the identifiers of access nodes connected to different wireless links 130, the identifiers of wireless links, etc.

[0051] The at least two wireless links 130 are used to connect different Access Points (APs) and receive downlink data sent by the APs. Among them, the different access nodes are access nodes in the same router.

[0052] In some embodiments, the terminal 100 further includes a display screen. The display screen is a display component for displaying a user interface. In some embodiments, the display screen is a display screen with a touch function. Through the touch function, the user can perform touch operations on the display screen with any suitable object such as a finger or a stylus. In some embodiments, the display screen is usually disposed on the front panel of the terminal 100. In some embodiments, the display screen is designed as a full-screen, curved-screen, irregular-shaped screen, double-sided screen, or foldable screen. In some embodiments, the display screen is also designed as a combination of a full-screen and a curved-screen, a combination of an irregular-shaped screen and a curved-screen, etc., and this embodiment does not limit this.

[0053] In addition, those skilled in the art can understand that the structure of the terminal 100 shown in the above drawings does not limit the terminal 100. The terminal 100 may include more or fewer components than those shown in the drawings, or combine certain components, or have different component arrangements. For example, the terminal 100 may also include components such as a microphone, a speaker, an input unit, a sensor, an audio circuit, a module, a power supply, a Bluetooth module, etc., which will not be elaborated here.

[0054] To increase the throughput of the wireless link in a wireless terminal and reduce network latency, the dual-band Wi-Fi acceleration method is usually adopted to enable the wireless terminal to connect to two APs simultaneously. Refer to Figure 2 , a wireless terminal integrated with a DBDC chip communicates and connects to different APs in a router through two different communication links (traffic links) via two wireless links respectively.

[0055] After the wireless terminal is connected to the AP, data interaction between the wireless terminal and the AP is not required most of the time. During the time when there is no data interaction between the wireless terminal and the AP, the AP periodically sends a beacon frame (Beacon) to the wireless terminal, and this Beacon is used to indicate whether there is downlink data that the AP needs to send to the wireless terminal. Therefore, to save power consumption, the wireless link of the wireless terminal is always in a sleep state, and only when it detects the Beacon indicating that the router has downlink data to send to the wireless terminal, the wireless terminal will wake up this wireless link to perform data interaction with the router based on this wireless link. Refer to Figure 3 , the wireless terminal generates a receiving current at the time corresponding to each beacon frame and receives the beacon frame through the receiving current.

[0056] After the wireless link is connected to the AP and there is no data interaction, a station sleep indication flag (Power Management Bit, PMB) is sent to the AP. Among them, this PMB flag is carried in a null data packet (null) transmitted between the wireless link and the access node, for example, in a null frame (null frame). This PMB is used to declare to the access node that the current wireless link enters the sleep (power save) state. Then the wireless link enters the sleep state and is woken up at a fixed time (Delivery Traffic Indication Target Beacon Transmission Time, DTIM TBTT) to receive the beacon frame sent by the AP. This beacon frame is used to indicate whether the wireless link needs to be fully woken up to receive the downlink data sent by the AP.

[0057] Correspondingly, after receiving the downlink data from the router side, the AP determines the state of the wireless link corresponding to the AP. In response to the state of the wireless link corresponding to the AP being the wake-up state, the downlink data is directly sent. In response to the state of the wireless link corresponding to the AP being the sleep state, the downlink data is stored, and when the next beacon frame is sent, the downlink data to be received by the wireless link is indicated through the beacon frame. See Figure 4 , after the wireless link receives the beacon frame, the wireless link is woken up, and a data packet carrying a PMB for indicating exiting the sleep state is sent to the AP, so that the AP sends downlink data to the wireless link. After receiving the wireless link, it re-enters the sleep state.

[0058] In the prior art, two wireless links in a WIFI chip are respectively connected to access nodes in different frequency bands. According to the protocol specification, the two wireless links respectively listen to their own beacon frames, and respectively determine whether to wake up and receive downlink data according to the beacon frames detected by themselves. See Figure 5 , when the two access nodes simultaneously receive the downlink data to be sent, and at this time both the first wireless link and the second wireless link are in the sleep state, the wake-up indication flags used to indicate that there is data to be sent in the beacon frames to be sent to the first wireless link and the second wireless link next time are respectively set to 1. Among them, the wake-up indication flag is represented by a bitmap at the position of the TIM IE or DTIM in the beacon frame. Then when there is data to be sent, the corresponding bitmap of the wireless link is set to 1. After the two wireless links receive the beacon frames containing the wake-up indication flags with wake-up information, they will respectively send indication information for indicating that they have exited the sleep state to the access nodes. After receiving the indication information, the access nodes send downlink data to the corresponding wireless links. Since the beacon frames are sent by different access nodes at different times, the wake-up times of different wireless links are also different, and there is a relative delay when the two wireless links receive the downlink data.

[0059] In the embodiment of the present application, for a wireless terminal including two wireless links, the two wireless links can be synchronously woken up through the beacon frames received by any one of the wireless links, and the access nodes corresponding to the two wireless links are synchronously notified that their corresponding wireless links have been woken up, so that the access nodes can synchronously send downlink data to the two wireless links, reducing the delay of the access nodes sending downlink data to the wireless links.

[0060] Please refer to Figure 6, which shows a flowchart of a method for controlling a wireless link according to an exemplary embodiment of the present application. The execution subject in the embodiment of the present application may be the wireless terminal 100, or the processor 110 in the wireless terminal 100 or the operating system in the wireless terminal 100. This embodiment is described by taking the execution subject as the wireless terminal 100 as an example. In the embodiment of the present application, an example is given in which the wireless terminal sends indication information to the access node respectively. The method includes:

[0061] Step 601: In response to the first wireless link being awakened, the wireless terminal sends first indication information to the first access node.

[0062] Wherein, the first indication information is used to indicate that the first wireless link is awakened. The first access point is the access point corresponding to the first wireless link. The first wireless link is a wireless link through which the terminal is connected to the first access node in the dual Wi-Fi communication mode. In the dual Wi-Fi communication mode, the wireless terminal is also connected to the second access node through the second wireless link. Wherein, the first wireless link and the second wireless link are processed by the same Wi-Fi chip for signals. And, the first wireless link and the second wireless link are wireless links connected to access nodes of the same or different frequency bands. For example, the first wireless link and the second wireless link are wireless links of frequency bands such as 2.4G, 5G, 6G, etc. In some embodiments, the first wireless link is a 2.4G wireless link and the second wireless link is a 5G wireless link. In some embodiments, the first wireless link is a 5G wireless link and the second wireless link is a 2.4G wireless link.

[0063] In this step, the wireless terminal receives a beacon frame sent by the first access node through the first wireless link. In response to the wake-up indication identifier for indicating the wake-up of the wireless link included in the beacon frame, the wireless terminal wakes up the first wireless link through the Wi-Fi chip. The wireless terminal also sends the first indication information to the first access node, and indicates to the first access node through the first indication information that the first wireless link has been awakened.

[0064] In addition, it should be noted that the frequency of the first wireless link is different from the frequency of the second wireless link. Or, the frequency of the first wireless link is the same as the frequency of the second wireless link.

[0065] It should be noted that the first indication information sent by the first wireless link when entering the sleep state is different from the first indication information sent by the first wireless link when leaving the sleep state. For example, when the first wireless link enters the sleep state, the first indication information sent includes a bitmap with PMB = 1; when the first wireless link leaves the sleep state, the first indication information sent includes a bitmap with PMB = 0.

[0066] Before this step, the wireless terminal determines whether the first wireless link is awakened. Refer to Figure 7 , the process of awakening the first wireless link is implemented through the following steps (1)-(2), including:

[0067] (1) The wireless terminal receives a beacon frame of the first wireless link from the first access node.

[0068] The beacon frame is a beacon frame generated by the first access node corresponding to the first wireless link. The first access node periodically sends beacon frames to the first wireless link. Correspondingly, when the first wireless link is in the sleep state, the wireless terminal periodically awakens the first wireless link to receive the beacon frame sent by the first access node. Among them, when the first access node does not store the information to be sent down, the wake-up indication flag of the beacon frame is set to non-wake-up information to generate the beacon frame. When the first access node stores the information to be sent down, the wake-up indication flag is set to wake-up information to generate the beacon frame.

[0069] Among them, the wake-up indication flag is the TIM IE (Traffic Indication Map Element) or DTIM (Delivery Traffic Indication) in the beacon frame. The TIM IE is used to indicate that the access node stores data sent to a certain wireless link. The DTIM is used to indicate that the access node stores data sent to multiple wireless links. Among them, the DTIM can reuse the position of the TIM IE in the beacon frame.

[0070] In this step, the first access node generates a beacon frame and sends the beacon frame to the wireless terminal through the first wireless link. Correspondingly, the wireless terminal receives the beacon frame through the first wireless link.

[0071] (2) The wireless terminal awakens the first wireless link in response to the beacon frame.

[0072] Among them, the wireless terminal parses the beacon frame and determines whether it is necessary to awaken the first wireless link based on the parsing result. When it is necessary to awaken the first wireless link, the step of awakening the first wireless link is executed. This process is implemented through the following steps (2-1)-(2-2), including:

[0073] (2-1) The wireless terminal parses the beacon frame to obtain the beacon frame parsing result.

[0074] In this step, the wireless terminal parses the received beacon frame to obtain the beacon frame parsing result. Among them, the beacon frame parsing result is used to indicate whether the first access node stores information that needs to be sent down. In response to the beacon frame parsing result indicating that there is no information to be sent down stored in the current first access node, the first wireless link is not awakened, and the wireless terminal re-enters the sleep state, waiting to wake up the first wireless link during the next listening period to continue listening for the beacon frame sent by the first access node. In response to the beacon frame parsing result indicating that there is downlink data to be sent stored in the current first access node, step (2-2) is executed.

[0075] (2-2) In response to the beacon frame parsing result indicating that there is information to be sent stored in the current first access node, the wireless terminal wakes up the first wireless link.

[0076] In this step, the wireless terminal wakes up the first wireless link and receives the information sent down by the first access node through the first wireless link.

[0077] In addition, since the first wireless link and the second wireless link are controlled by the same Wi-Fi chip in the wireless terminal, correspondingly, after the first wireless link is awakened, the wireless terminal wakes up the second wireless link through this Wi-Fi chip so as to receive the downlink data sent by the second access node through the second wireless link. The process is as follows: In response to the first wireless link being awakened, the wireless terminal wakes up the second wireless link. Among them, the wireless terminal determines the link identifier of the second wireless link, generates a wake-up instruction according to the link identifier of the second wireless link, and wakes up the second wireless link based on the wake-up instruction.

[0078] Among them, the second access node and the first access node are access nodes in the same router. Or, the second access node and the first access node are access nodes in different routers. In the embodiments of the present application, no specific limitation is made in this regard.

[0079] In this implementation manner, the first wireless terminal wakes up the first wireless link and the second wireless link through the received beacon frame sent by the first access node, so that when the wireless terminal receives the wake-up indication of any wireless link, it can wake up the two wireless links in the wireless terminal, ensuring that both wireless links can receive information.

[0080] Step 602: The wireless terminal sends second indication information to the second access node on the second wireless link.

[0081] Among them, the second indication information is used to indicate that the second wireless link exits the sleep state.

[0082] In this step, when the wireless terminal receives the wake-up instruction of the first wireless link, it actively sends a data packet including the second indication information on the second wireless link. SeeFigure 8 After the first wireless link receives the beacon frame, it sends the first indication information and the second indication information to the first access node and the second access node respectively according to the parsing result of the beacon frame.

[0083] Among them, the wireless terminal generates a data packet based on the second indication information, and sends the second indication information to the second access node by sending the data packet to the second access node. See Figure 9 This process is implemented through the following steps (1)-(2), including:

[0084] (1) The wireless terminal determines the link identifier of the second wireless link.

[0085] In this step, the wireless terminal obtains the link identifier of the second wireless link in the same dual-Wi-Fi communication mode as the first wireless link through the Wi-Fi chips corresponding to the first wireless link and the second wireless link.

[0086] (2) The wireless terminal sends the second indication information to the second access node on the second wireless link based on the link identifier.

[0087] In this step, the wireless terminal sets the value corresponding to the second indication information at the position corresponding to the link identifier in the data packet. Among them, the data packet is any data packet that can carry the second indication information. For example, the data packet is a null data packet, or a management frame, a data frame, and a control frame of other 802.11 frame structures. In the embodiments of the present application, the form of the data packet is not specifically limited. The wireless terminal sends the data packet to the second access node through the second wireless link.

[0088] In this implementation manner, the wireless terminal generates the second indication information for indicating that the second wireless link is awakened based on the link identifier of the second wireless link, so as to inform the second access node that the second wireless link has exited the sleep state, so that the two wireless links can receive the information sent by the access node at the same time, reducing the time interval for the two wireless links to receive information in the dual-Wi-Fi communication mode.

[0089] After the first wireless link and the second wireless link are awakened, the wireless terminal receives information from the first access node on the first wireless link respectively. And, receive information from the second access node on the second wireless link.

[0090] Continue to refer to Figure 8 After the first wireless link and the second wireless link of the wireless terminal receive the downlink data, they both re-enter the sleep state. Correspondingly, the first access node and the second access node continue to send beacon frames periodically.

[0091] In an embodiment of the present application, when the first wireless link is awakened, indication information for indicating that the wireless link is awakened is sent to the first wireless network connected to the first wireless link and the second wireless network connected to the second wireless link at the same time, so that the two wireless links can be awakened synchronously, enabling the two wireless links to receive the information sent by the access node simultaneously, and reducing the time interval for the two wireless links to receive information in the dual Wi-Fi communication mode.

[0092] Please refer to Figure 10 , which shows a flowchart of a method for controlling a wireless link shown in an exemplary embodiment of the present application. The execution subject in the embodiment of the present application may be the wireless terminal 100, or the processor 110 in the wireless terminal 100 or the operating system in the wireless terminal 100. This embodiment is described by taking the execution subject as the wireless terminal 100 as an example. In the embodiment of the present application, an example is given in which the wireless terminal sends indication information to the first access node, and the first access node sends wake-up information to the second access node. The method includes:

[0093] Step 1001: The wireless terminal sends third indication information to the access node.

[0094] The indication information includes a first sub-information and a second sub-information. The first sub-information indicates the status information of the wireless terminal, and the second sub-information indicates whether the wireless terminal is in the dual Wi-Fi communication mode. The status information of the wireless terminal refers to whether the wireless link of the wireless terminal is in the wake-up state or the sleep state. In the dual Wi-Fi communication mode, the wireless terminal includes a first wireless link and a second wireless link. The first wireless link and the second wireless link are wireless links for the wireless terminal to perform data interaction with different access nodes in the dual Wi-Fi communication mode. Among them, the first wireless link performs data interaction with the first access node, and the second wireless link performs data interaction with the second access node. The first access node and the second access node are access nodes in the same router. In the embodiment of the present application, no specific limitation is made thereto.

[0095] In one implementation, after the two wireless links of the wireless terminal establish network connections with different access nodes in the router, the router will generate identifiers for the two wireless links respectively, and allocate the identifier to the wireless terminal through the first wireless link and the second wireless link respectively. Correspondingly, before this step, the router allocates an identifier to the wireless terminal, and the identifier is exchanged between the first access node and the second access node. See Figure 11, the process is as follows: The first access node in the router assigns a first identifier to the wireless terminal via a first wireless link; and sends the first identifier to the second access node, and receives from the second access node a second identifier assigned to the wireless terminal via a second wireless link. Correspondingly, the second access node in the router receives the first identifier sent by the first access point, assigns a second identifier to the wireless terminal via the second wireless link; and sends the second identifier to the first access node, and receives from the first access node the first identifier assigned to the wireless terminal via the first wireless link.

[0096] In this implementation, the developer modifies the sleep indication rules of the access node and the wireless link in advance. Add a second sub - information to the third indication information, and indicate through the added second self - information whether the current third indication information is used to indicate whether the current wireless link is in the dual - Wi - Fi communication mode.

[0097] Correspondingly, the wireless terminal generates the third indication information based on the current different scenarios and different preset conditions of the wireless terminal. This process is implemented through the following steps (1) - (2), including:

[0098] (1) The wireless terminal determines the first sub - information and the second sub - information.

[0099] Among them, the first sub - information indicates the status information of the wireless terminal, and the second sub - information indicates the Wi - Fi communication mode applied by the wireless terminal. The second sub - information is a newly added sub - information. For example, the second sub - information is a newly added dual - link interface string (dual_link bit). The first sub - information is the original sleep indication identifier, such as PMB.

[0100] In this step, the wireless terminal determines the second sub - information based on the current Wi - Fi communication mode. Determine the first sub - information based on the status of the current first wireless link and the second wireless link. Refer to Table 1. In response to the second sub - information being the first value, the second sub - information is used to indicate that the current third indication information represents the status of the current one network link. In response to the second sub - information being the second data, the second sub - information is used to indicate that the current third indication information represents the status of the two wireless links in the current dual - Wi - Fi communication mode. Among them, the first value and the second value are set as needed, and are not specifically limited in the embodiments of the present application. For example, the first value is 0 or 1, and the second value is 0 or 1.

[0101] Table 1

[0102]

[0103] Referring to Table 1, when the second sub - information is 0, determine that the current third indication information indicates the state of the wireless link that sends the third indication information; when the second sub - information is 1, determine that the current third indication information indicates the states of multiple wireless links in the dual - Wi - Fi communication mode where the wireless link that sends the third indication information is located. When the first sub - information is 0, it is used to indicate that the wireless link wakes up from the sleep state; when the second sub - information is 1, it is used to indicate that the wireless link enters the sleep state.

[0104] Among them, in this embodiment, these two sub - information represent that in the dual - Wi - Fi communication mode, all wireless links of the wireless terminal enter the sleep state, or in the single - Wi - Fi communication mode, only the wireless link that sends this indication information enters the sleep state. The wireless terminal determines the second sub - information based on the current communication mode, and determines the first sub - information based on the state of the wireless link. In response to the wireless terminal only needing to indicate the state of the current wireless link through the third indication information, the wireless terminal determines that the second sub - information is 0; in response to the wireless terminal needing to indicate the states of the current wireless link and other wireless links in the dual - Wi - Fi communication mode through the third indication identifier, the wireless terminal determines that the second sub - information is 1. The wireless terminal determines the first sub - information based on the information of entering or exiting the sleep state that is currently to be executed. In response to the wireless link entering the sleep state, the value of the first sub - information is 1; in response to the wireless link exiting the sleep state, the value of the first sub - information is 0.

[0105] In some embodiments, the wireless link entering the sleep state includes the wireless link receiving the information sent by the access node and then entering the sleep state. Correspondingly, the wireless link sends the third indication information to the access node, and the third indication information includes the first sub - information and the second sub - information. Among them, the first sub - information indicates that the wireless terminal enters the sleep state, and the second sub - information indicates that the wireless terminal is in the dual - Wi - Fi communication mode. For example, in response to the wireless terminal determining to enter the sleep state, the wireless terminal sends the indication information to the access node, where the first sub - information indicates that the wireless terminal enters the sleep state, and the second sub - information indicates whether the wireless terminal is in the dual - Wi - Fi communication mode.

[0106] In other embodiments, when a predetermined condition is met, the indication information including the first sub - information and the second sub - information is sent to the access node. Among them, the first sub - information indicates that the wireless terminal exits the sleep state, and the second sub - information indicates that the wireless terminal is in the dual - Wi - Fi communication mode. The predetermined condition includes: the access node wakes up the wireless link; or the access node wakes up the wireless link and sends downlink data to the wireless link through the wireless link; or the wireless terminal actively wakes up the wireless link.

[0107] (2) The wireless terminal generates the third indication information based on the first sub - information and the second sub - information.

[0108] In this implementation manner, by changing the structural type of the third indication information, the third indication information can indicate the states of multiple wireless links in the dual - Wi - Fi communication mode, thereby being able to indicate the states of two wireless links, enabling the two wireless links to receive data sent by the access node simultaneously, and reducing the time interval for receiving information.

[0109] Step 1002: The router receives the third indication information from the wireless terminal.

[0110] In this step, the router receives the third indication information sent by the wireless terminal according to the first access node corresponding to the first wireless link. Wherein, the router is the router where the first access node is located. In some embodiments, the router includes multiple access nodes. The frequency bands corresponding to the multiple access nodes are the same or different. For example, the multiple access nodes respectively correspond to the frequency bands of 2.4 GHz, 5 GHz or 6 GHz.

[0111] In some embodiments, if the third indication information is used to indicate that the current wireless link exits the sleep state or enters the sleep state, the router directly records the state of the wireless link corresponding to the third indication information as the wake - up state or the sleep state.

[0112] In some embodiments, the third indication information is used to indicate that the current terminal is in the dual - Wi - Fi communication mode, that is, it means that all wireless links of the wireless terminal have exited the sleep state through the first sub - information and the second sub - information. Then the router executes step 1003 to send a wake - up message to the second access node.

[0113] Step 1003: The router sends a wake - up message to the second access node, indicating that the second wireless link has exited the sleep mode.

[0114] In this step, after the router determines that the third indication information indicates that the current first wireless link and the second wireless link are awakened, the router determines the link identifier of the first wireless link based on the first wireless link that receives the third indication information, determines the second identifier of the second wireless link in the same dual - Wi - Fi communication mode as the first wireless link based on the pre - stored correspondence of wireless links in the dual - Wi - Fi communication mode, and sends a wake - up message to the second access node based on the second identifier corresponding to the second wireless link. This process is implemented through the following steps (1) - (2), including:

[0115] (1) The router parses the third indication information to obtain a parsing result.

[0116] The router parses the third indication information to obtain the first sub - information and the second sub - information in the third indication information. The router determines the indication result of the third indication information, i.e., the current states of the first wireless link and the second wireless link, based on the parsed first sub - information and second sub - information.

[0117] (2) In response to the parsing result indicating that the first sub - information indicates that the wireless terminal exits the sleep state and the second sub - information is used to indicate that the wireless terminal is in the dual - Wi - Fi communication mode, the router determines that the parsing result is that the current first wireless link and the second wireless link are awakened.

[0118] Referring to Table 1, when the second sub - information is 0, it is determined that the current third indication information indicates the state of the wireless link that sends the third indication information currently; when the second sub - information is 1, it is determined that the current third indication information indicates the states of multiple wireless links in the dual - Wi - Fi communication mode where the wireless link that sends the third indication information is located. When the first sub - information is 0, it is used to indicate that the wireless link exits the sleep state and is awakened; when the first sub - information is 1, it is used to indicate that the wireless link enters the sleep state. In this step, in response to the second sub - information being 1 and the first sub - information being 0, the router determines that the third indication information indicates that the current first wireless link and the second wireless link are awakened.

[0119] After both the first wireless link and the second wireless link are awakened, the first access point of the router sends information to the wireless terminal in the first wireless link; the second access point sends information to the wireless terminal in the second wireless link. Refer to Figure 12 , after the first wireless link feeds back the third indication information, the router sends downlink data through the first access node and the second access node respectively.

[0120] It should be noted that after the first wireless link and the second wireless link receive the information, they can re - enter the sleep state and send the third indication information to the router to indicate that the first wireless link or the second wireless link enters the sleep state. In some embodiments, the first wireless link and the second wireless link send the third indication information to the first access node and the second access node respectively. Among them, the second sub - information of the third indication information is 0 and the first sub - information is 1, which is used to indicate that the wireless link that sends the third indication information enters the sleep state. In some embodiments, any one of the first wireless link and the second wireless link sends the third indication information to its corresponding access node. Among them, the second sub - information of the fourth indication information is 1 and the first sub - information is 1, which is used to indicate that multiple wireless links in the dual - Wi - Fi communication mode where the wireless link that sends the third indication information is located enter the sleep state.

[0121] In this implementation, by modifying the communication protocol, the same indication information is used to indicate the status of different access nodes in the router for different wireless links, so that in the dual Wi-Fi communication mode, when any wireless link is awakened, the indication information fed back through this wireless link indicates that multiple wireless links in the router are awakened, enabling the access node to simultaneously send downlink data to the wireless links, thereby reducing the time interval for receiving downlink data.
