Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a data sending method, an electronic device, a chip system, and a storage medium. Background Art

[0002] Wireless fidelity (Wi-Fi) technology is a widely used wireless network transmission technology. With the increasing popularity and rapid growth of Wi-Fi devices, Wi-Fi usage scenarios are increasing, and Wi-Fi devices can communicate with multiple devices at the same time. For example, one application scenario is: the mobile phone works in the wireless workstation (STA) mode to connect to the access point (AP) to access the Internet. At the same time, the mobile phone also works in the Wi-Fi peer-to-peer (P2P) mode for file sharing or screen projection services.

[0003] Currently, when a Wi-Fi device communicates with multiple devices simultaneously, the Wi-Fi device can work on the same channel of a single frequency band. The Wi-Fi device uses time division multiplexing to send data, which results in high-priority services not being scheduled in time and increases data transmission delay. Summary of the invention

[0004] The embodiments of the present application provide a data sending method, an electronic device, a chip system, and a storage medium. When the electronic device uses the same frequency and the same channel to perform Wi-Fi communication with two other devices, data priority is taken into consideration when sending service data, and high-priority data is given the opportunity to be sent first, thereby reducing transmission delay.

[0005] In a first aspect, a data transmission method is provided, which is applied to a first electronic device, wherein the first electronic device performs a first service through a first Wi-Fi connection with a second electronic device, and the first electronic device performs a second service through a second Wi-Fi connection with a third electronic device, and both the first Wi-Fi connection and the second Wi-Fi connection use a first channel of a first frequency band; the method includes: obtaining first data of the first service at a first moment, and obtaining second data of the second service at a second moment; before the first moment, the priority of the first data is lower than the priority of the second data; sending the second data at a third moment, and sending the first data at a fourth moment; and the third moment is before the fourth moment.

[0006] The data transmission method provided in the first aspect is applicable to the scenario where the electronic device simultaneously communicates with multiple devices through Wi-Fi and the electronic device operates in SBSC mode. The electronic device obtains data of different services according to the time when the data arrives at the Wi-Fi chip. When sending data, the sending order is determined according to the priority of the data, and high-priority data is sent first, so that high-priority data has the opportunity to be sent first. In the SBSC mode, the transmission delay of high-priority services is reduced, and the QoS requirements of the services are guaranteed.

[0007] In one possible implementation, when the first electronic device communicates with the second electronic device, the first electronic device operates in STA mode and the second electronic device operates in AP mode; when the first electronic device communicates with the third electronic device, both the first electronic device and the third electronic device operate in Wi-Fi P2P mode.

[0008] In a possible implementation manner, the second service is a Wi-Fi P2P service.

[0009] In one possible implementation, the second service is a screen projection service or a file sharing service.

[0010] In a possible implementation, the second data includes at least one of the following: projection data, video data, or audio data. By setting at least one of the projection data, video data, or audio data as high-priority data, the projection data, video data, or audio data has a chance to be sent first, thereby shortening the data transmission delay and meeting the delay requirement.

[0011] In a possible implementation, the first frequency band is the Wi-Fi 5 GHz frequency band.

[0012] In a possible implementation, there are multiple first data and at least one second data, and the number of second data sent at the third moment is greater than the number of first data sent at the fourth moment. By sending a larger number of high-priority data each time, the transmission delay of the high-priority data is further shortened.

[0013] In a possible implementation, before obtaining the first data of the first service at the first moment and obtaining the second data of the second service at the second moment, the method further includes: running the first application to set the priority of the first data for the first data; and running the second application to set the priority of the second data for the second data. By setting priorities for data of different services, it is convenient to send data according to the priority in the future, thereby ensuring the QoS requirements of the services.

[0014] In a possible implementation, when the first electronic device sends data, it can obtain the first service message to be sent; determine whether the first service message has a priority; if it is determined that the first service message has a priority, then according to the corresponding relationship between the preset M priorities and N queues, divide the first service message into the target queue corresponding to the priority of the first service message; where M and N are integers greater than 1, and the number of service messages sent by the first electronic device in the i-th queue each time is greater than or equal to the number of service messages sent in the (i + 1)-th queue, 1 ≤ i < M, and the priority corresponding to the i-th queue is higher than the priority corresponding to the (i + 1)-th queue; if it is determined that the first service message does not have a priority, then divide the first service message into the first queue; where the number of service messages sent by the first electronic device in the first queue each time is the minimum value among the N queues; and send the service messages in each queue in turn according to the sorting of the N queues.

[0015] In a possible implementation, each queue is set with a weight value, and the weight value is used to determine the number of service messages sent by the first electronic device in this queue each time.

[0016] In a possible implementation, the weight value is the number of service messages sent by the first electronic device in the queue each time; or, the weight value is the ratio between the number of service messages sent by the first electronic device in the queue each time and a preset number.

[0017] In a possible implementation, the weight value of the i-th queue is greater than or equal to the weight value of the (i + 1)-th queue.

[0018] In a possible implementation, if the first service message has a priority, the priority of the first service message is carried in the first field of the first service message.

[0019] In a possible implementation, if the first service message has a priority, the priority of the first service message is carried in the encapsulation structure of the first service message.

[0020] In a possible implementation, the encapsulation structure includes an skb structure.

[0021] In one possible implementation, the business messages in each queue are sent in sequence according to the order of N queues, including: obtaining the number of business messages remaining in the first queue according to the order of the N queues; determining whether the number of business messages remaining in the first queue is less than the number of business messages in the first queue sent by the first electronic device each time; if it is determined that the number of business messages remaining in the first queue is less than the number of business messages in the first queue sent by the first electronic device each time, sending the remaining business messages in the first queue; if it is determined that the number of business messages remaining in the first queue is greater than or equal to the number of business messages in the first queue sent by the first electronic device each time, sending the business messages in the first queue according to the number of business messages in the first queue sent by the first electronic device each time; obtaining the number of business messages remaining in the second queue, performing the above-mentioned operations on the first queue for the second queue, and so on, until the business messages in the last queue are sent.

[0022] In a possible implementation, M is greater than or equal to N.

[0023] In a second aspect, a device is provided, comprising: a unit or means for executing each step of the above first aspect.

[0024] In a third aspect, an electronic device is provided, including a processor, which is connected to a memory and is used to call a program stored in the memory to execute the method provided in the first aspect above. The memory can be located inside the electronic device or outside the electronic device. The processor includes one or more and the memory includes one or more.

[0025] In a fourth aspect, a chip system is provided, including a processor, wherein the processor is coupled to a memory, and the processor executes a computer program stored in the memory to perform the method provided in the first aspect above.

[0026] According to a fifth aspect, a program is provided, which, when executed by a processor, is used to execute the method according to the first aspect.

[0027] In a sixth aspect, an embodiment of the present application provides a computer-readable storage medium, in which instructions are stored. When the instructions are executed on a computer or a processor, the method provided in the first aspect above is implemented.

[0045] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0046] The data transmission method provided in the embodiment of the present application can be applied to the scenario where the terminal device performs Wi-Fi communication with multiple devices at the same time. Figure 1 This is a schematic diagram of an application scenario applicable to the embodiment of the present application. Figure 1 As shown, mobile phone A can simultaneously communicate with router B and projection device C through Wi-Fi. For example, when mobile phone A communicates with router B through Wi-Fi, mobile phone A can work in STA mode, and router B works in AP mode. AP manages and controls STA to form a wireless network, which is mainly used for application scenarios such as Internet access. Among them, the AP mode can provide wireless access services, allow other wireless devices to access, and provide data access. General wireless routers / bridges work in this mode. APs are allowed to connect to each other. The STA mode is similar to a wireless terminal. The STA itself does not accept wireless access. It can be connected to the AP. Generally, the wireless network card works in this mode. Mobile phone A and projection device C can communicate through Wi-Fi P2P. Both mobile phone A and projection device C work in Wi-Fi P2P mode. Wi-Fi P2P, also known as Wi-Fi Direct, can realize direct communication between two devices without an AP. It is mainly used in application scenarios such as file transfer and data transfer. Common terminal devices, such as mobile phones, can play different roles in different scenarios. For example, when accessing the Internet through hotspots such as routers, they can act as STAs; when sharing hotspots, they can also act as APs; during P2P communication, they can act as one end.

[0047] Need to explain, Figure 1 There is no limitation on the working mode when mobile phone A communicates with multiple devices through Wi-Fi at the same time.

[0048] It should be noted that the embodiments of the present application do not limit the services implemented by the terminal device through Wi-Fi communication. Figure 1In the example, after mobile phone A is wirelessly connected to router B, mobile phone A can run a chat application (application, APP), a browser APP, and an email APP. By running the chat APP, mobile phone A can send or receive text messages, or make voice calls, or make video calls. By running the browser APP, mobile phone A can allow users to browse the web or watch videos. By running the email APP, mobile phone A can send or receive emails. Mobile phone A can implement screen projection services by performing Wi-Fi P2P communication with screen projection device C, and the content displayed on the screen of mobile phone A can be projected and displayed on screen projection device C. For example, in another implementation method, a file sharing service can be performed between mobile phone A and screen projection device C.

[0049] It should be noted that the embodiments of the present application do not limit the name and type of the terminal device, and do not limit the number and type of other devices that the terminal device simultaneously performs Wi-Fi communication. The terminal device may also be referred to as an electronic device. At present, some examples of terminal devices are: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, etc.

[0050] When a terminal device communicates with multiple devices through Wi-Fi at the same time, there is no limit on the operating frequency band and operating channel of the terminal device. Currently, terminal devices can operate in three modes: single band single concurrent (SBSC), dual band dual concurrent (DBDC), and dual band adaptive concurrent (DBAC). Figure 2 to Figure 4 Provide explanation.

[0051] 1.SBSC

[0052] In SBSC mode, terminal devices can operate on the same channel in a single frequency band. Figure 2 As shown, when mobile phone A communicates with router B through Wi-Fi, channel 149 in the 5GHz band is used. When mobile phone A communicates with screen projection device C through Wi-Fi P2P, channel 149 in the 5GHz band is also used. Since mobile phone A works on the same channel in a single frequency band, mobile phone A can communicate with router B or screen projection device C at a certain time through time division multiplexing of radio frequency resources, and the latency performance is poor. For example, mobile phone A sends a chat APP-related message to router B at time T1, and sends a screen projection service message to screen projection device C at time T2.

[0053] 2. DBDC

[0054] In DBDC mode, terminal devices can work on different frequency bands, or on different channels of a single frequency band. Mobile phone A can use frequency division multiplexing to multiplex radio frequency resources. At a certain moment, mobile phone A can communicate with router B and projection device C at the same time, with better latency performance.

[0055] Optionally, in one implementation, as Figure 3 As shown, mobile phone A uses the 2.4GHz frequency band to communicate with router B via Wi-Fi, and uses the 5GHz frequency band to communicate with projection device C via Wi-Fi P2P.

[0056] Optionally, in another implementation, such as Figure 4 As shown, mobile phone A uses channel 36 of the 5GHz frequency band to communicate with router B via Wi-Fi, and uses channel 149 of the 5GHz frequency band to communicate with projection device C via Wi-Fi P2P.

[0057] 3. DBAC

[0058] In DBAC mode, the terminal device can operate on different channels of a single frequency band. For example, see Figure 4 , mobile phone A uses channel 36 of the 5GHz band to communicate with router B via Wi-Fi, and uses channel 149 of the 5GHz band to communicate with screen projection device C via Wi-Fi P2P. Mobile phone A can communicate with router B or screen projection device C at a certain moment by time-division multiplexing radio frequency resources.

[0059] Combine the following Figure 5 to Figure 7 An exemplary description is given of a structure applicable when the terminal equipment works in SBSC, DBDC or DBAC. Figure 5 to Figure 7 The difference lies in the number of Wi-Fi modules and radio frequency modules included in the terminal device. Figure 5As shown, the terminal device may include an application processing module 11, a Wi-Fi module 12 and a radio frequency module 13. Figure 6 As shown, the terminal device may include an application processing module 11, a first Wi-Fi module 121, a second Wi-Fi module 122, a first radio frequency module 131, and a second radio frequency module 132. Figure 7 As shown, the terminal device may include an application processing module 11, a first Wi-Fi module 121, a second Wi-Fi module 122 and a radio frequency module 13. Among them, the application processing module can be used to process the first data related to the upper-layer application installed in the terminal device. The Wi-Fi module can be used to process the second data according to the wireless local area network (WLAN) protocol. The embodiment of the present application does not limit the WLAN protocol, for example, the Institute of Electrical and Electronics Engineers (IEEE) 802 series protocol. The radio frequency module can be used to send or receive third data. The embodiment of the present application does not limit the specific content of the first data, the second data and the third data, for example, it can include service messages processed by the upper-layer application. It can be understood that the functional modules included in the terminal device can be hardware and / or software modules.

[0060] When the terminal equipment works in SBSC mode, the structure can be seen in Figure 5 to Figure 7 . Combined Figure 1 , Optionally, in one implementation, mobile phone A may include 1 radio frequency module, for example Figure 5 or Figure 7 The RF module 13 in the mobile phone A is used by the mobile phone A to communicate with the router B or the projection device C. If there are multiple Wi-Fi antennas, the Wi-Fi antenna is used by one RF module, which can achieve multi-input multi-output (MIMO) and improve the channel capacity and spectrum efficiency, for example, 2*2 Wi-Fi MIMO. Optionally, in another implementation, the mobile phone A can include two RF modules, for example Figure 6 The RF module 131 and the RF module 132 in the mobile phone A are time-division multiplexed to realize communication with the router B or with the screen projection device C. At this time, the Wi-Fi antenna is used by the RF module 131 and the RF module 132 respectively, and the RF module 131 and the RF module 132 can jointly realize 2*2 Wi-Fi MIMO.

[0061] Optionally, in one implementation, mobile phone A may include a Wi-Fi module, for example Figure 5 The Wi-Fi module 12 in the router B and the services between the mobile phone A and the screen projection device C are processed by the Wi-Fi module 12. Optionally, in another implementation, the mobile phone A may include two Wi-Fi modules, for example Figure 6 or Figure 7 The first Wi-Fi module 121 and the second Wi-Fi module 122 in the mobile phone A and the router B and the mobile phone A and the screen projection device C can be processed by a Wi-Fi module respectively. For example, the first Wi-Fi module 121 is used to process the business between the mobile phone A and the router B, and the second Wi-Fi module 122 is used to process the business between the mobile phone A and the screen projection device C.

[0062] When the terminal device works in DBDC mode, the structure can be seen in Figure 6 Optionally, in one implementation, Figure 1 and Figure 3 , Figure 6 The first Wi-Fi module 121 and the first radio frequency module 131 in the embodiment can operate in the 2.4 GHz frequency band to implement the service between the mobile phone A and the router B. The second Wi-Fi module 122 and the second radio frequency module 132 can operate in the 5 GHz frequency band to implement the service between the mobile phone A and the projection device C. Optionally, in another implementation, Figure 1 and Figure 4 , Figure 6 The first Wi-Fi module 121 and the first radio frequency module 131 can operate in the 5 GHz low frequency band to implement services between mobile phone A and router B. The second Wi-Fi module 122 and the second radio frequency module 132 can operate in the 5 GHz high frequency band to implement services between mobile phone A and projection device C.

[0063] In DBDC mode, the Wi-Fi antennas are used by two RF modules respectively. The 2*2 Wi-Fi MIMO mode in SBSC will degenerate to the 2.4 GHz 1*1+5 GHz 1*1 mode, or to the 5 GHz 1*1+5 GHz 1*1 mode, or to the 2.4 GHz 1*1+2.4 GHz 1*1 mode, thus losing the MIMO performance.

[0064] When the terminal device works in DBAC mode, the structure can be seen in Figure 7 . Combined Figure 1 and Figure 4 Mobile phone A can communicate with router B or screen projection device C by time division multiplexing radio frequency module 13. Figure 7The first Wi-Fi module 121 can operate in the 5 GHz low frequency band, and is used to implement the service between the mobile phone A and the router B. The second Wi-Fi module 122 can operate in the 5 GHz high frequency band, and is used to implement the service between the mobile phone A and the projection device C.

[0065] In practical applications, the terminal device can adopt at least one of SBSC, DBDC or DBAC. For example, the terminal device can select different modes according to factors such as the type of terminal device, the hardware and software structure of the terminal device, the mode pre-configured by the terminal device, and the type of service implemented by the terminal device. Among them, for the SBSC mode, since multiple Wi-Fi antennas can work in the same frequency and channel to realize MIMO, the channel capacity and spectrum efficiency are improved. However, because the time-division multiplexing RF module sends data, high-priority services cannot be scheduled in time, the data transmission delay increases, and the quality of service (QoS) of the service cannot be guaranteed.

[0066] Combine the following Figure 8 , an exemplary description is given of sending service messages when the terminal device works in SBSC mode.

[0067] like Figure 8 As shown, mobile phone A works in SBSC mode. After mobile phone A is wirelessly connected to router B, mobile phone A can run chat APP, browser APP and email APP in response to user instructions. Chat APP involves voice service messages and video service messages. For example, user A uses chat APP to send a voice short message to user B. Accordingly, mobile phone A obtains the audio signal input by user A, and a voice service message can be generated by running chat APP. For another example, user A uses chat APP to make a video call with user B. Accordingly, mobile phone A obtains the audio signal input by user A through the microphone, and the image of user A can be obtained through the camera, and a video service message can be generated by running chat APP. Browser APP involves web service messages. For example, user A uses browser APP to browse web pages. Accordingly, mobile phone A can generate web service messages by running browser APP. Email APP involves email service messages. For example, user A uses email APP to edit and send emails to user C. Accordingly, mobile phone A can generate email service messages by running email APP. After mobile phone A establishes a Wi-Fi P2P connection with screen projection device C, mobile phone A can generate screen projection service messages by running the screen projection APP or the system application that comes with the mobile phone system.

[0068] After mobile phone A generates a service message, the service message arrives at the Wi-Fi chip randomly. Mobile phone A obtains the message queue before scheduling and sends the service message according to the message queue. Figure 8As shown, the messages included in the message queue before scheduling are arranged in the order of message arrival. For the convenience of explanation, each message in the message queue is numbered, and the smaller the number, the message arrives first, and the larger the number, the message arrives later. Assume that the message queue before scheduling includes 13 messages, numbered 0 to 12, message 0 arrives first, and message 12 arrives last. Among them, messages 0 and 9 are video service messages, messages 1, 5, and 10 are voice service messages, messages 4 and 7 are web service messages, message 6 is an email service message, and messages 2, 3, 8, 11, and 12 are screen projection service messages. Mobile phone A sends messages in sequence according to the order of arrangement of each message in the message queue before scheduling. The message sending order is the same as the order of arrangement of the messages in the message queue before scheduling, that is, message 0 is sent first and message 12 is sent last.

[0069] It can be seen that when the terminal device works in SBSC mode, the terminal device uses time division multiplexing to send data, and sends it in sequence according to the order in which the messages arrive, resulting in high-priority services not being scheduled in time. For example, the priority of the screen projection service message is higher, but when the arrival time is later than other types of messages, it cannot be sent in time, the delay increases, and the QoS of the service cannot be guaranteed.

[0070] The embodiment of the present application provides a data sending method, which is suitable for a scenario in which a terminal device simultaneously performs Wi-Fi communication with multiple devices and the terminal device operates in SBSC mode. The terminal device can obtain the priority of the service message and divide the service message into different queues according to the priority of the service message. Among them, the terminal device can add priority to the service message when running the upper-layer application. Each queue corresponds to a weight value, and the weight value is used to determine the number of service messages in the queue sent by the terminal device each time. The terminal device sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues. Since the terminal device takes the priority of the service message into consideration when sending the service message, the high-priority service message is given the opportunity to be sent first. In the SBSC mode, the gain of simultaneous operation of multiple Wi-Fi antennas is obtained, and the transmission delay of high-priority services is reduced, thereby ensuring the QoS requirements of the service.

[0071] It should be noted that the service message in the embodiment of the present application can be transmitted through Wi-Fi communication, and the name of the service message is not limited, for example, it can also be called service data, service data packet, message, etc. For the sake of convenience, the embodiment of the present application is described by taking the service message as an example.

[0072] It should be noted that the embodiment of the present application does not limit the number of queues. The number of queues can be any integer greater than 1.

[0073] It should be noted that the embodiment of the present application does not limit the value of the weight value of each queue. The weight values ​​of different queues may be the same or different. There are at least two values ​​in the weight values ​​corresponding to all queues. For example. In one example, there are 4 queues, marked as queues 1 to 4, and the corresponding weight values ​​are 4, 2, 1, and 1, respectively. The weight value may be the number of service messages sent by the terminal device in the queue each time. Then, the terminal device may send 4 messages in queue 1, 2 messages in queue 2, 1 message in queue 3, or 1 message in queue 4 each time. In another example, there are 3 queues, marked as queues 1 to 3, and the corresponding weight values ​​are 3, 2, and 1, respectively. The weight value may be the ratio between the number of service messages sent by the terminal device in the queue each time and the preset number. For example, if the preset number is 1, then the terminal device may send 3 messages in queue 1, 2 messages in queue 2, or 1 message in queue 3 each time. For another example, if the preset number is 2, then the terminal device can send 6 (weight value 3×preset number 2) messages in queue 1, 4 (2×2) messages in queue 2, or 2 (1×2) messages in queue 3 each time.

[0074] It should be noted that the number of business messages in the queue sent by the terminal device each time refers to the maximum number that can be sent. In actual transmission, if the number of business messages remaining in the queue is large, greater than or equal to the maximum number, the terminal device can send the maximum number of business messages in the queue. If the number of business messages remaining in the queue is small, less than the maximum number, the terminal device can send all remaining business messages in the queue. For example, according to the weight value, it is determined that the number of business messages in queue 1 sent by the terminal device each time is 6. Then, when the number of remaining messages in queue 1 is 7, the terminal device can send 6 messages, and when the number of remaining messages in queue 1 is 5, the terminal device can send 5 messages.

[0075] It should be noted that the embodiment of the present application does not limit the correspondence between the queue and the priority of the service message. Optionally, the number of queues and the number of priorities can be the same, and there can be a one-to-one correspondence between the queues and the priorities. For example, there are 4 queues, marked as queues 1 to 4. There are 4 priorities for service messages, marked as priorities 1 to 4, with priority 1 being the highest and priority 4 being the lowest. Service messages of priorities 1 to 4 can be divided into queues 1 to 4 respectively. Optionally, the number of queues can be less than the number of priorities, and there is at least one queue, which corresponds to at least two priorities. For example, there are 3 queues, marked as queues 1 to 3. There are 5 priorities for service messages, marked as priorities 1 to 5, with priority 1 being the highest and priority 5 being the lowest. In one implementation, service messages of priority 1 can be divided into queue 1, service messages of priority 2 to 3 can be divided into queue 2, and service messages of priority 4 to 5 can be divided into queue 3. In another implementation, service packets of priority 1 may be classified into queue 1, service packets of priority 2 may be classified into queue 2, and service packets of priority 3 to 5 may be classified into queue 3. The weight value of the queue corresponding to the high priority is greater than or equal to the weight value of the low priority queue.

[0076] It should be noted that the embodiment of the present application does not limit the correspondence between the type of service message and the priority of the service message. Optionally, the number of types of service messages and the number of priorities can be the same, and the types of service messages and priorities can correspond one to one. For example, there are 4 types of service messages, marked as types 1 to 4. There are 4 priorities of service messages, marked as priorities 1 to 4, with priority 1 being the highest and priority 4 being the lowest. Types 1 to 4 of service messages correspond one to one with priorities 1 to 4 of service messages, for example, type 1 of service messages corresponds to priority 1 of service messages. Optionally, the number of types of service messages is greater than the number of priorities, and there is at least one priority, which corresponds to at least two types of service messages. For example, there are 3 priorities of service messages, marked as priorities 1 to 3. There are 5 types of service messages, marked as types 1 to 5. In one implementation, type 1 of service messages corresponds to priority 1, types 2 to 3 of service messages correspond to priority 2, and types 4 to 5 of service messages correspond to priority 3. In another implementation, type 1 of the service message corresponds to priority 1, type 2 of the service message corresponds to priority 2, and types 3 to 5 of the service message correspond to priority 3.

[0077] It should be noted that the embodiment of the present application does not limit the type of service message, and different implementation methods may be used according to the settings of the terminal device or the type of the upper layer application. Optionally, the type of service message may include but is not limited to at least one of the following: voice service message, video service message, web service message, email service message, game service message, screen projection service message or file sharing service message.

[0078] It should be noted that the embodiment of the present application does not limit the correspondence between the upper layer application and the service message type. An application may involve at least one type of service message, for example, Figure 8 As shown, the chat APP may involve voice service messages and video service messages.

[0079] It should be noted that the data sending method provided in the embodiment of the present application can be applied in one scenario: multiple types of applications are installed on the terminal device, and the application that comes with the system is also installed. Due to different developers and versions of the application, some applications support adding priority to the service message, and some applications do not support adding priority to the service message. Correspondingly, the terminal device may add priority to the service message by running different applications, or it may not add priority to the service message. In the embodiment of the present application, the service message has no priority and can also be understood as having the lowest level of priority. For example, there are 3 queues, marked as queues 1 to 3. There are 3 priorities for the service message, marked as priority 1 to 3, with priority 1 being the highest and priority 3 being the lowest. In one implementation, the service message of priority 1 can be divided into queue 1, the service message of priority 2 can be divided into queue 2, the service message of priority 3 and the service message without priority can be divided into queue 3. In another implementation, the service message of priority 1 can be divided into queue 1, the service message of priority 2 to 3 can be divided into queue 2, and the service message without priority can be divided into queue 3.

[0080] Combine the following Figures 9 to 13 , an exemplary description is given of a terminal device sending a service message after adopting the data sending method provided in an embodiment of the present application. Figures 9 to 13 For the types of service messages and the message queues before scheduling, see Figure 8 In each example, the weight value of the queue directly indicates the number of service packets in the queue sent by the terminal device each time.

[0081] Optionally, in one example, Fig. 9As shown, there are 5 priorities for service messages, marked as priorities 1 to 5, with priority 1 being the highest and priority 5 being the lowest. The priorities of screen projection service messages, video service messages, voice service messages, web service messages, and email service messages are priority 1 to 5, respectively. There are 5 queues, marked as queues 1 to 5. Mobile phone A can obtain the priority of each message in the message queue before scheduling, and divide the service messages into different queues according to the priority of the service messages. Specifically, service messages of priority 1 to 5 are divided into queues 1 to 5 respectively. Queue 1 includes messages 2, 3, 8, 11, and 12, all of which are screen projection service messages. Queue 2 includes messages 0 and 9, all of which are video service messages. Queue 3 includes messages 1, 5, and 10, all of which are audio service messages. Queue 4 includes messages 4 and 7, all of which are web service messages. Queue 5 includes message 6, which is an email service message. The weight values ​​of queues 1 to 5 are 5, 4, 3, 2, and 1, respectively, that is, mobile phone A can send 5 messages in queue 1, 4 messages in queue 2, 3 messages in queue 3, 2 messages in queue 4, or 1 message in queue 5 at a time. Mobile phone A sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues, and the message sending order (expressed by digital numbers) is: 2, 3, 8, 11, 12, 0, 9, 1, 5, 10, 4, 7, 6. It can be seen that since the terminal device considers the priority of the service message when sending the service message, the high-priority service message has the opportunity to be sent first. For example, mobile phone A gives priority to sending the screen projection service message and sends 5 messages each time, which reduces the transmission delay of the high-priority service when the terminal device works in the SBSC mode, and ensures the QoS requirements of the service. Moreover, although the proportion of low-priority business messages sent is small, for example, the email business message is in queue 5, and mobile phone A sends one email business message each time, the low-priority business messages will not be completely deprived of the opportunity to be sent, and the functions of low-priority services will not be affected.

[0082] Alternatively, in another example, Fig.10 As shown in the figure, there are 4 service message priorities, marked as priority 1 to 4, with priority 1 being the highest and priority 4 being the lowest. There are 4 queues, marked as queues 1 to 4. Service messages with priorities 1 to 4 are divided into queues 1 to 4 respectively. This example is different from Fig. 9 The difference between the examples shown is that in this example, one priority can correspond to multiple types of service messages. For example, the priorities of web service messages and email service messages are both priority 4. After mobile phone A classifies the service messages, queues 1 to 3 are Fig. 9The queues 1 to 3 in the table are the same, and queue 4 includes messages 4, 6, and 7, including web service messages and email service messages. The weight values ​​of queues 1 to 4 are 4, 2, 1, and 1, respectively. Mobile phone A sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues. The messages sent in the first round (indicated by digital numbers) include: 2, 3, 8, 11, 0, 9, 1, and 4. The remaining messages in each queue include: message 12 in queue 1, messages 5 and 10 in queue 3, and messages 6 and 7 in queue 4. Mobile phone A continues to send the service messages in each queue according to the weight values ​​corresponding to the multiple queues. The messages sent in the second round include: 12, 5, and 6, and the messages sent in the third round include: 10 and 7. Finally, the message sending order is: 2, 3, 8, 11, 0, 9, 1, 4, 12, 5, 6, 10, and 7.

[0083] Optionally, in yet another example, Fig.11 As shown in the figure, there are 5 service message priorities, marked as priority 1 to 5, with priority 1 being the highest and priority 5 being the lowest. There are 4 queues, marked as queues 1 to 4. Fig. 9 The difference between the examples shown is that in this example, one queue can correspond to multiple service message priorities. For example, service messages of priority 4 and 5 can be classified into queue 4. After mobile phone A classifies the service messages, queues 1 to 3 are Fig. 9 The queues 1 to 3 in the example are the same, and the queue 4 includes messages 4, 6, and 7, including web service messages and email service messages. The weight values ​​of queues 1 to 4 are 4, 2, 1, and 1 respectively. Mobile phone A sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues. The message sending order is the same as Fig.10 The same is not repeated here.

[0084] Optionally, in yet another example, Fig.12 As shown in the figure, there are three priorities for service messages, marked as priority 1 to 3, with priority 1 being the highest and priority 3 being the lowest. The priority of screen projection service messages is priority 1, the priority of video service messages and voice service messages is priority 2, and the priority of email service messages is priority 3. There are three queues, marked as queues 1 to 3. This example is different from Figures 9-11The difference between the examples shown is that in this example, some service messages do not have priority, for example, web service messages do not have priority. In this example, service messages of priority 1 can be divided into queue 1, service messages of priority 2 can be divided into queue 2, and service messages of priority 3 and no priority can be divided into queue 3, and the weight value of queue 3 is the smallest. After mobile phone A classifies the service messages, queue 1 includes messages 2, 3, 8, 11, and 12, all of which are screen projection service messages. Queue 2 includes messages 0, 1, 5, 9, and 10, including voice service messages and video service messages. Queue 3 includes messages 4, 6, and 7, including web service messages and email service messages. The weight values ​​of queues 1 to 3 are 4, 2, and 1, respectively. Mobile phone A sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues. The messages sent in the first round (indicated by digital numbers) include: 2, 3, 8, 11, 0, 1, 4; the messages sent in the second round include: 12, 5, 9, 6; and the messages sent in the third round include: 10, 7.

[0085] Optionally, in yet another example, Fig.13 As shown in the figure, there are 4 service message priorities, marked as priority 1 to 4, with priority 1 being the highest and priority 4 being the lowest. There are 4 queues, marked as queues 1 to 4. Fig.12 The difference between the examples shown is that in this example, the service messages without priority are separately divided into one queue, and the weight value of the queue is the minimum value among the weight values ​​of all queues, for example, it is divided into queue 4. After mobile phone A classifies the service messages, queue 1 includes messages 2, 3, 8, 11, and 12, all of which are screen projection service messages. Queue 2 includes messages 0 and 9, all of which are video service messages. Queue 3 includes messages 1, 5, 6, and 10, including voice service messages and email service messages. Queue 4 includes messages 4 and 7, including web service messages, without priority. The weight values ​​of queues 1 to 4 are 4, 2, 2, and 1, respectively. Mobile phone A sends the service messages in each queue in turn according to the weight values ​​corresponding to the multiple queues. The messages sent in the first round (indicated by digital numbers) include: 2, 3, 8, 11, 0, 9, 1, 5, and 4, and the messages sent in the second round include: 12, 6, 10, and 7.

[0086] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0087] Fig.14 A flow chart of a data transmission method provided in an embodiment of the present application. The data transmission method provided in this embodiment can be executed by a terminal device. Fig.14 As shown, the data sending method provided in this embodiment may include:

[0088] S1401. Obtain a first service message to be sent.

[0089] The first service message is a service message that can be transmitted via Wi-Fi communication, and can be a service message that is processed by an upper-layer application and then transmitted to a bottom-layer Wi-Fi chip.

[0090] The embodiments of the present application do not limit the developers and functions of the upper-layer application. Optionally, the application can be an application that comes with the terminal device system, such as a browser, an email application, or a smart home application, etc. The system's built-in application may be different for different types of terminal devices. Optionally, the application can be an application developed by a third party and installed by the user on the terminal device, such as a browser, a chat APP, a video APP, or a file sharing APP, etc.

[0091] S1402: Determine whether the first service message has a priority.

[0092] The first service message may or may not have a priority, which is related to the upper-layer application that processes the first service message. For example, some applications that come with the terminal device system may support adding priorities to service messages, and the first service message has a priority. Some applications developed by a third party may not support adding priorities to service messages, and the first service message does not have a priority.

[0093] If the first service message has a priority, S1403 is executed. If the first service message does not have a priority, S1404 is executed.

[0094] When the first service message has a priority, the embodiment of the present application does not limit the manner in which the first service message carries the priority.

[0095] Optionally, in one implementation, the priority may be carried in a field of the service message. Optionally, the field may be an existing field in the service message. Optionally, the priority may reuse some bits in the existing field, or occupy reserved bits in the existing field. Optionally, the field may be a reserved field in the service message. Optionally, the field may be a newly added field in the service message.

[0096] The format of the service message and the field carrying the priority in the service message are exemplified below through Table 1, but Table 1 does not limit this. Table 1 shows the message format specified in the 802.3 protocol. The first service message can carry the priority by using the "user priority" part in the multiplexing field "Q-Tag". In the embodiment of the present application, a correspondence between the priority and the queue is pre-established.

[0097] Table 1

[0098] Fields Destination Address Source Address Q Tags Length / Type Data / LLC Frame Check Sequence Number of bytes 6 bytes 6 bytes 4 bytes 2 bytes 46 to 1500 bytes 4 bytes

[0099] The destination address consists of 6 bytes and indicates the destination address of the service message.

[0100] The source address (sourceaddress) consists of 6 bytes and indicates the source address of the service message.

[0101] The Q tag (Q-Tag) consists of 4 bytes, the first two bytes are the tag protocol identifier (TAG protocol identifier, TPID), and the last two bytes are the tag control information (TAG control information, TCI). TCI consists of 3 parts: user priority (user_priority), canonical format indicator (canonical format indicator, CFI) and virtual network identifier (VLAN ID, VID). User priority occupies 3 bits and can represent up to 8 different priorities. CFI occupies 1 bit. When the value is 0, it means that the media access control (media access control, MAC) address format in the service message is in the standard format. When the value is 1, it has different meanings depending on the network type. VID occupies 12 bits and represents the identifier of the virtual local area network (VLAN).

[0102] Data / LLC consists of 46 to 1500 bytes. LLC stands for logical link control, and the logical link control protocol is defined in IEEE 802.2.

[0103] The frame check sequence consists of 4 bytes.

[0104] For a detailed description of each field, please refer to the 802.3 protocol and will not be repeated here.

[0105] Optionally, in another implementation, the priority can be encapsulated in the encapsulation structure of the Wi-Fi message, for example, in a Linux system, it can be encapsulated in a socket buffer (skb). The skb consists of two parts: message data and management data. Among them, the message data saves the actual transmitted data, for example, the message format specified in the IEEE 802 series protocol. The management data includes additional data for the kernel to process the message, for example, control information exchanged between different protocols. After an application transmits data to a socket, the socket will create a corresponding socket buffer and copy the data to the buffer.

[0106] It should be noted that the embodiment of the present application does not limit the position of the priority in the encapsulation structure of the Wi-Fi message and the number of bits occupied.

[0107] S1403: If the first service message has a priority, according to a preset correspondence between the M priorities and the N queues, the first service message is divided into a target queue corresponding to the priority of the first service message.

[0108] Wherein, M and N are integers greater than 1, and M is greater than or equal to N. A queue is set with a weight value, and the weight value is used to determine the number of service messages in the queue sent by the terminal device each time. The weight value of the queue corresponding to the first priority among the M priorities is greater than or equal to the weight value of the queue corresponding to the second priority, and the first priority is higher than the second priority.

[0109] The embodiment of the present application does not limit the specific values ​​of M and N, the corresponding relationship between M priorities and N queues, and the specific value of the weight value of each queue. Figures 9 to 13 The relevant description will not be repeated here.

[0110] In the embodiment of the present application, N queues also have priorities, and the weight value of the high-priority queue is greater than or equal to the weight value of the low-priority queue. For queue A corresponding to the high priority among the M priorities and queue B corresponding to the low priority among the M priorities, the priority of queue A is higher than the priority of queue B. When the terminal device sends a service message, it will give priority to sending the service message in the high-priority queue and then send the service message in the low-priority queue. For example. In one example, Fig. 9 As shown, M priorities include priorities 1 to 5, priorities 1 to 5 correspond to queues 1 to 5 respectively, and the priorities of queues 1 to 5 gradually decrease, with queue 1 having the highest priority and queue 5 having the lowest priority. The weight values ​​of queues 1 to 5 are 5, 4, 3, 2, and 1 respectively, and the weight value of the high priority queue is greater than the weight value of the low priority queue. In another example, Fig.11As shown, the M priorities include priorities 1 to 5. Priority 1 corresponds to queue 1, priority 2 corresponds to queue 2, priority 3 corresponds to queue 3, and priorities 4 to 5 correspond to queue 4. The priorities of queues 1 to 4 gradually decrease, with queue 1 having the highest priority and queue 4 having the lowest priority. The weight values ​​of queues 1 to 4 are 4, 2, 1, and 1, respectively. Among them, the priority of queue 3 is higher than that of queue 4, and the weight value of queue 3 is the same as that of queue 4. When sending service messages, the terminal device will give priority to sending service messages in queue 3 and then send service messages in queue 4.

[0111] S1404: If the first service message does not have a priority, the first service message is divided into a first queue, wherein a weight value of the first queue is a minimum value among weight values ​​of the N queues.

[0112] Specifically, for a service message that does not have a priority, the terminal device classifies the service message into a first queue with the lowest priority.

[0113] Optionally, in one implementation, the service packets in the first queue may include service packets without priority and service packets with low priority among the M priority levels. Fig.12 As shown, service messages of priority 3 and those without priority are all divided into queue 3.

[0114] Optionally, in another implementation, the service messages in the first queue may include service messages that do not have priority. Fig.13 As shown, service messages without priority are all divided into queue 4.

[0115] S1405 . Send the service messages in each queue in descending order of priority of the N queues according to the weight value of the queue.

[0116] Specifically, in order of priority from high to low, for the first queue with the highest priority, determine the number of business messages that the terminal device can send each time (marked as Q) according to the weight value of the queue, and determine whether the current number of business messages in the queue is greater than or equal to Q. If the current number of business messages in the queue is greater than or equal to Q, the terminal device sends the Q business messages in the queue. If the current number of business messages in the queue is less than Q, the terminal device sends all business messages in the queue. Then, for the second queue with a lower priority than the first queue, send the business messages in the second queue in accordance with the processing method of the first queue, and so on, until the business messages in the last queue with the lowest priority are sent. Afterwards, the terminal device cyclically sends the business messages in the N queues in order of priority from high to low. Exemplary, the process of sending business messages can be seen in Figures 9 to 13 Related description in .

[0117] It can be seen that the data sending method provided in this embodiment can be applied to the scenario where the terminal device simultaneously performs Wi-Fi communication with multiple devices and the terminal device works in SBSC mode. After the terminal device obtains the first service message to be sent, it determines whether the first service message has priority. When the first service message has priority, the first service message can be divided into the target queue corresponding to the priority of the first service message according to the corresponding relationship between the priority and the queue. When the first service message does not have priority, the first service message can be divided into the queue with the lowest priority. Each queue corresponds to a weight value. The terminal device sends the service messages in each queue in order from high to low according to the weight values ​​corresponding to the multiple queues. Since the terminal device considers the priority of the service message when sending the service message, the high-priority service message gets the opportunity to be sent first. In the SBSC mode, the transmission delay of the high-priority service is reduced, and the QoS requirements of the high-priority service are guaranteed. Moreover, although the proportion of low-priority service messages sent is small, they will not be completely unable to get the opportunity to send, and the function of the low-priority service will not be affected.

[0118] Optionally, the data sending method provided in this embodiment may further include:

[0119] A first application is run, and a priority is added to the first service message.

[0120] The first application supports adding priority to the service message. The embodiment of the present application does not limit the developer and function of the first application. The first application can be an application that comes with the terminal device system, or an application developed by a third party and installed on the terminal device.

[0121] The first application is related to the first service message. Optionally, the first service message may be a service message generated when the terminal device runs the first application. Optionally, the first service message may be a service message obtained by the first application from other processing modules of the terminal device.

[0122] Optionally, adding a priority to the first service message may include:

[0123] According to the correspondence between the type of the service message and the priority of the service message, the priority corresponding to the type of the first service message is added to the first service message.

[0124] It should be noted that the embodiment of the present application does not limit the correspondence between the type of business message and the priority of the business message.

[0125] It should be noted that the implementation method of the priority is not limited in the embodiment of the present application. For example, if there are 8 priorities, the value can be a decimal number of 0 to 7, represented by 3 bits. It can be defined that the value 0 represents the highest priority and the value 7 represents the lowest priority, or it can be defined that the value 0 represents the lowest priority and the value 7 represents the highest priority.

[0126] It is understandable that, in order to implement the above functions, the terminal device includes hardware and / or software modules corresponding to the execution of each function. In combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application in combination with the embodiments, but such implementation should not be considered to be beyond the scope of this application.

[0127] The embodiment of the present application can divide the functional modules of the terminal device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0128] In the case of dividing each functional module into corresponding functional modules, Fig.15 A schematic diagram of the structure of a terminal device provided in an embodiment of the present application. Fig.15 As shown, the terminal device can be used as a first electronic device and can include: a processing module 1501 and a sending module 1502.

[0129] The processing module 1501 is used to obtain first data of a first service at a first moment, and obtain second data of a second service at a second moment. Before the first moment, the priority of the first data is lower than the priority of the second data. The first electronic device performs the first service through a first Wi-Fi connection with the second electronic device, and the first electronic device performs the second service through a second Wi-Fi connection with the third electronic device, and both the first Wi-Fi connection and the second Wi-Fi connection use a first channel of a first frequency band.

[0130] The sending module 1502 is used to send the second data at a third moment and send the first data at a fourth moment; the third moment is before the fourth moment.

[0131] It should be noted that all relevant contents of each step involved in the above method embodiment can be referred to the functional description of the corresponding functional module and will not be repeated here.

[0132] Among them, the processing module can be a processor or a controller. It can implement or execute various exemplary logic boxes, modules and circuits described in conjunction with the disclosure of this application. The processor can also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of digital signal processing (DSP) and a microprocessor, etc. The storage module can be a memory. The sending module can specifically be a device that interacts with other electronic devices, such as a radio frequency circuit, a Bluetooth chip, a Wi-Fi chip, etc.

[0133] The embodiment of the present application also provides a terminal device. Fig.16 Another structural schematic diagram of a terminal device provided in an embodiment of the present application.

[0135] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the terminal device 100. In other embodiments of the present application, the terminal device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0136] The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0137] The controller may be the nerve center and command center of the terminal device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0138] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0139] In some embodiments, the processor 110 may include one or more interfaces. The interface may include an Inter-Integrated Circuit (I2C) interface, an Inter-Integrated circuit Sound (I2S) interface, a Pulse Code Modulation (PCM) interface, a Universal Asynchronous Receiver / Transmitter (UART) interface, a Mobile Industry Processor Interface (MIPI), a General-Purpose Input / Output (GPIO) interface, a Subscriber Identity Module (SIM) interface, and / or a Universal Serial Bus (USB) interface, etc.

[0140] The I2C interface is a bidirectional synchronous serial bus, including a serial data line (SDA) and a serial clock line (SCL). In some embodiments, the processor 110 may include multiple groups of I2C buses. The processor 110 may be coupled to the touch sensor 180K, the charger, the flash, the camera 193, etc. through different I2C bus interfaces. For example: the processor 110 may be coupled to the touch sensor 180K through the I2C interface, so that the processor 110 communicates with the touch sensor 180K through the I2C bus interface, thereby realizing the touch function of the terminal device 100.

[0141] The I2S interface can be used for audio communication. In some embodiments, the processor 110 can include multiple I2S buses.
