technical field

The present application relates to the field of communication technologies, and in particular, to a data transmission method and an electronic device.

Background technique

With the development of network communication technology, there are more and more real-time applications (that is, applications requiring high timeliness of data transmission), and at the same time, more and more users use real-time applications. Therefore, users have higher and higher requirements on the timeliness of data transmission in communication networks.

However, when multiple devices access the same wireless access point, such as an access point based on Wireless-Fidelity (Wi-Fi) technology, the access point is based on a first-come, first-served basis. Allocate air interface resources to each device. As a result, the device may not be able to request network resources in time according to the actual service requirements, thereby failing to meet the low-latency service requirements of the device.

SUMMARY OF THE INVENTION

When a set condition is met, the wireless access point sends instruction information indicating activation of the low-latency feature, and instructs the wireless access point to give priority to the electronic device's Business data is sent.

Detailed ways

The embodiments of the present application provide a data transmission method, which can be applied between electronic devices that communicate based on Wi-Fi technology. The above Wi-Fi technology is a wireless local area network technology established by the Wi-Fi Alliance based on the 802.11 standard of the Institute of Electrical and Electronic Engineers (IEEE).

Exemplarily, after the device 1 supporting the Wi-Fi technology accesses the device 2 supporting the Wi-Fi technology through the Wi-Fi protocol, the device 1 and the device 2 can communicate based on the Wi-Fi protocol.

It should be noted that the device 1 described in the embodiments of the present application may be an electronic device supporting Wi-Fi, and may also be referred to as a station (station, STA). Exemplarily. The above-mentioned device 1 may be a mobile phone, a television, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, a personal computer (PC), a netbook, a cellular phone, a personal digital assistant (PDA) , wearable devices (such as smart watches), car computers, game consoles, cameras, speakers, and augmented reality (AR) \ virtual reality (virtual reality, VR) devices and other Wi-Fi-enabled electronic devices. The specific form of the device 1 is not particularly limited in this embodiment of the present application.

The device 2 described in this embodiment of the present application may be an electronic device with an access point (access point, AP) capability, that is, an electronic device that can access a Wi-Fi network. For example, device 2 may be a router.

Of course, in some possible embodiments, the above-mentioned device 2 may also be an electronic device supporting Wi-Fi Direct. For example, the device 2 may also be a mobile phone, a television, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, a personal computer (personal computer, PC), and the like.

Understandably, whether it is the device 2 with AP capability or the device 2 supporting Wi-Fi direct connection, it can be referred to as a wireless access point.

Generally, the above-mentioned process of the device 1 accessing the device 2 can be divided into a scanning phase, an identity authentication phase and an association phase. As an example, as shown in (a) of FIG. 1 , the above scanning phase may be that device 1 sends probe request information to device 2, such as a probe request frame, triggering device 2 to send probe response information to device 1, such as probe respond frame. As another example, as shown in (b) of FIG. 1 , in the above-mentioned scanning phase, the device 2 may actively send out a beacon frame, such as a Beacon frame. Therefore, the device 1 can obtain the beacon frame sent by the device 2 by scanning.

That is, in the scanning phase, the device 1 can decide whether to access the device 2 according to the received probe respond frame or Beacon frame. When the device 1 determines to access the device 2, the identity authentication stage is entered.

In the identity authentication phase, the device 1 sends an identity authentication request, such as an Authentication request frame, to the device 2 to obtain an identity authentication response returned by the device 2, such as an Authentication respond frame.

As an implementation manner, the above-mentioned identity authentication request carries information indicating the authentication algorithm type, for example, carries information indicating that the authentication algorithm type is Shared Key. In response to the identity authentication request, device 2 feeds back a plain text challenge to device 1. After the device 1 encrypts the challenge plaintext with the preset key, it obtains the challenge cipher text (Cipher text challenge), and sends it to the device 2. Device 2 decrypts the received challenge ciphertext and compares it with the challenge plaintext. If they are consistent, device 2 sends an identity authentication response to device 1, thereby completing identity authentication.

After completing identity authentication, device 1 also needs to send an association request to device 2, such as an associationrequest frame. Device 2 replies to device 1 with an association response, eg, an association respond frame. After that, device 1 can communicate with device 2.

Of course, other devices supporting the Wi-Fi technology can also access the device 2 in the same way. Obviously, the device 2 serving as an AP can be simultaneously accessed by multiple devices supporting the Wi-Fi technology. However, the air interface resources (time domain resources, frequency domain resources, etc.) that can be provided by device 2 are limited. After multiple Wi-Fi technology-enabled devices are connected, they need to follow the round-robin scheduling method to access each access in turn. The device allocates air interface resources. This also means that after the air interface resources of the device 2 are occupied, the newly connected device needs to wait. That is, when there are multiple devices supporting Wi-Fi technology accessing the device 2, because the air interface resources of the device 2 are insufficient, on the one hand, the device 2 cannot create a packet data unit for the newly accessed device 1 in time. unit, PDU) session, on the other hand, device 2 cannot schedule air interface resources in time for device 1 to send service data to the Wi-Fi network side, thereby causing device 1 to experience data transmission delays.

In this scenario, it is difficult for device 1 to meet the data transmission requirements of real-time applications.

As shown in FIG. 2 , a mobile phone (device 1), a tablet computer (other devices), and a notebook computer (other devices) all need to be connected to a router (device 2) for example.

In the scenario shown in FIG. 2 , when a mobile phone starts a real-time application, such as a real-time online game, it needs to perform data interaction with the game server through a router, such as transmitting service data 1 . When the tablet computer starts the live video, it needs to receive the live data stream transmitted by the live server through the router, such as the transmission of business data 2. When the laptop starts the chat application, it needs to exchange data with the chat server through the router, such as transmitting business data3. The above service data is data generated by an application running in the device and needs to be sent through the device 2 .

In the scenario shown in Figure 2, after the router creates a PDU session for the tablet, laptop, and mobile phone, it allocates air interface resources for the service data sent by the tablet, laptop, and mobile phone according to the round-robin scheduling method. It may occur that the time for sending service data 1 by using air interface resources is later than that of service data 2 and service data 3.

However, from the perspective of applications running on various devices, real-time online games used by mobile phones have high requirements on the timeliness of data transmission, and the amount of data to be transmitted is small. The live video that needs to be used by the tablet computer has the next requirement on the timeliness of data transmission, and the amount of data to be transmitted is large. The chat application to be used by the laptop has low requirements on the timeliness of data transmission.

That is, in the related art, the low-latency service requirements of real-time applications running in the mobile phone cannot be guaranteed. For example, a serious delay occurs on the mobile phone, so that the real-time online game cannot be started normally, which affects the user experience.

In order to improve the above problems, the embodiments of the present application provide a data transmission method. The above method includes: after the device 1 accesses the device 2, the device 1 requests the device 2 to start the low-latency service, and the low-latency service can improve the data transmission priority of the device 1. Therefore, the device 2 is urged to preferentially create a PDU session for the device 1, and to preferentially send the service data of the device 1, so as to avoid the problem of data transmission delay in the device 1.

Exemplarily, as shown in FIG. 3 , when the first STA (ie, device 1) and the second STA access the AP (ie, device 2), the first STA, the second STA and the AP constitute data transmission system. If the first STA sends indication information 1 to the AP, it is also referred to as the first indication information. The above-mentioned indication information 1 is used to instruct to start the low-latency service. Under the condition that the AP supports the low-latency feature and can provide the first STA with the low-latency service, the AP may provide the first STA with the low-latency service. During the low-latency service period, even if the AP receives the service data of the second STA first, the AP will preferentially use the air interface resources to send the service data sent by the first STA. Therefore, the waiting time of the device 1 is reduced, and the transmission time consumption of the service data of the device 1 is shortened. Therefore, the timeliness of data transmission of the device 1 is improved.

For example, when a tablet computer, a laptop computer, and a mobile phone are successively connected to the router, as shown in Figure 4, the mobile phone (the first STA) applies for a low-latency service, but the tablet computer and the laptop computer (the second STA) do not In the case of applying for low-latency service, the transmission priority of service data 1 in the router is higher than that of service data 2 and service data 3. In this way, the router will preferentially use the air interface resources to transmit service data 1, so as to improve the problem of data transmission delay in the mobile phone. Improve user experience.

In some embodiments, before the first STA sends the indication information 1, in the same period, the service data sent by the first STA to the AP may be called the first service data, and the service data sent by the second STA to the AP may be called the first service data. 2. Business data. After the first STA sends the indication information 1, in the same period, the service data sent by the first STA to the AP may be called third service data. In some embodiments, the third service data may refer to all service data sent by the first STA to the AP. In other embodiments, the third service data may refer to service data of real-time applications sent by the first STA to the AP. The service data sent by the second STA to the AP may be referred to as fourth service data. In addition, the fourth service data may also refer to service data sent by a device that has not applied for a low-latency service.

The methods in the following embodiments can all be implemented in a device having the above-mentioned hardware structure.

The method provided by the embodiment of the present application is described below by taking the device 1 as a mobile phone and the device 2 as a router as an example.

In an embodiment of the present application, as shown in FIG. 6 , the above data transmission method may include the following steps:

S101, the router sends a beacon frame.

The above-mentioned beacon frame is a Wi-Fi frame sent periodically, and is also called a Beacon frame. The router allows external devices, such as mobile phones, tablet computers, laptops and other Wi-Fi-enabled devices, to discover the router by sending beacon frames.

In some embodiments, the above-mentioned beacon frame may include characteristic information of the router, such as low-latency characteristic information. The above feature information can be used to indicate whether the router supports various features, for example, can be used to indicate whether the low-latency feature is supported. As an example, the above-mentioned feature information for indicating whether the low-latency feature is supported may be included in a reserved field in the beacon frame, such as a vendor-specific field (vendor-specific) in the Beacon frame.

For example, referring to FIG. 7 , it shows the frame structure of the Beacon frame 700 provided by the embodiment of the present application. As shown in FIG. 7 , the above-mentioned Beacon frame 700 includes a frame header (ie, a MAC header) 701 , a frame body (frame body) 702 and a frame check sequence (FCS) field 703 . The above-mentioned MAC header 701 is a media access control (media access control, MAC) header.

The frame header 701 includes frame control, duration, address, station MAC address (BSSID), sequence control and high throughput control (HTControl). The frame control field has type type=00 and subtype subtype=1000.

The frame body 702 includes a field (Fields that are not information element) 7021 and a field (Fields that are information element) 7022 of an information element. The field 7022 of the above-mentioned information element is composed of a plurality of information elements. Each of the above information elements may include elements such as element ID (element ID), length (Length) and information (information). The types of the above information elements include SSID fields, supported rates (supported rates), extended supported rates (extended supported rates), and "vendor-specific" fields. In some embodiments, the type corresponding to the information element can be distinguished by the element ID of the information element.

Exemplarily, the information element with the element ID of 211 is the "vendor-specific" field, the information element with the element ID of 0 is the "SSID" field, the information element with the element ID of 1 is the "Rates" field, and so on. For the fields corresponding to the information elements of other element IDs, reference may be made to the introduction in the Wi-Fi protocol, and details are not repeated here.

In some embodiments, the "vendor-specific" field in the beacon frame may include, in addition to the element ID, Length, information, and an organizationally unique identifier (OUI). Among them, OUI is used to indicate the organization that defines the field.

As an example, the length corresponding to the above "vendor-specific" may be 9. The information corresponding to the above-mentioned "vendor-specific" may include a value, and the above-mentioned value may include 6 bytes. Different bytes correspond to different meanings, that is, carry different information contents.

For example, Value[0], the first byte in Value, is used to indicate the type of the field. For example, Value[0] can be 0x01, which is used to indicate that the information element is a vendor-specific field. Value[1] is the second byte in Value, 1 byte reserved for scalability, Value[1] can be set to rsv. Value[2:3], the third and fourth bytes in Value, are used to enumerate properties. The correspondence between different property types and different values can be predefined. For example, if it is pre-defined that 0x0001 refers to the low-latency feature, the value corresponding to Value[2:3] is 0x0001, indicating that the enumerated feature is the low-latency feature. In this way, when Value[2:3] takes other values, it can also be used to indicate other characteristics of the enumeration. Value[4:5], that is, the fifth and sixth bytes in Value, are used to indicate whether the enumerated features are supported. For example, when Value[4:5] is 0x0001, it is used to indicate that the device supports it; for example, when Value[4:5] can be 0x0000, it is used to indicate that the device does not support it. Of course, when Value[4:5] is 0x0000, it can be used to indicate that the device supports it; when Value[4:5] is 0x0001, it can be used to indicate that the device does not support it.

In this way, the mobile phone can determine whether the router supports the low-latency feature according to the "vendor-specific" field in the beacon frame. For example, identify the value of Value[4:5] from the vendor-specific whose element ID is 221 and Value[2:3] is 0x0001 in the beacon frame. If Value[4:5] is 0x0001, then The mobile phone confirms that the router supports the low-latency feature. If the Value[4:5] value is 0x0000, the mobile phone confirms that the router does not support the low-latency feature.

It is understandable that a router that supports the low-latency feature can provide low-latency services to connected devices. Therefore, the router can notify external devices (ie, Wi-Fi devices that discover the router, such as mobile phones) that the router can provide low-latency services by sending a beacon frame containing a beacon frame indicating that the low-latency feature is supported. In this way, an external device (eg, a mobile phone) can also decide whether to request a low-latency service from the router accordingly.

Of course, in other embodiments, the beacon frame may also not carry characteristic information indicating whether the low-latency characteristic is supported. For example, in a scenario where all routers can support the low-latency feature, the beacon frame sent by the routers may not carry feature information indicating whether the low-latency feature is supported.

S102, the mobile phone sends an identity authentication request to the router in response to the beacon frame.

In some embodiments, the above-mentioned identity authentication request may be an Authentication request frame.

S103, the router sends an identity authentication response to the mobile phone.

In some embodiments, the above-mentioned authentication response may be an Authentication respond frame.

The above S102 and S103 may be an identity authentication link for the mobile phone to access the router. In some embodiments, it can be implemented in the manner of Shared key. Of course, other methods can also be used for identity authentication. For the implementation process, reference may be made to related technologies and protocols, which will not be repeated here. In the case that the router sends an identity authentication response to the mobile phone to indicate that the identity authentication is passed, the process proceeds to S104.

S104, the mobile phone initiates an association request to the router.

In some embodiments, the above association request may be an association request frame.

S105, the router sends an association response to the mobile phone.

In some embodiments, the association response described above may be an association respond frame.

The above-mentioned S104 and S105 may be an association link for the mobile phone to access the router. For the implementation process, reference may be made to related technologies and protocols, which will not be repeated here.

In some embodiments, if the preset condition is satisfied, the process proceeds to S106.

Exemplarily, the above-mentioned satisfying the preset condition includes that the association between the mobile phone and the router is successful.

For another example, satisfying the preset conditions further includes that after the mobile phone and the router are successfully associated, the mobile phone starts a real-time application, such as a real-time online game.

In addition, in another exemplary manner, satisfying the preset condition further includes that the mobile phone determines that the router supports the low-latency feature.

In some embodiments, if all routers support the low-latency feature by default, the mobile phone also supports the low-latency feature by default on all accessible routers. In this way, the beacon frame may not carry an indication whether the low-latency feature is supported. Identifier of the delay characteristic. In other embodiments, the mobile phone can also determine whether the router supports the low-latency feature according to the feature information carried in the beacon frame, and the principle may refer to the description in the foregoing embodiments. Therefore, invalid air interface interaction is reduced, and the data interaction efficiency between the mobile phone and the router is improved.

S106, the mobile phone sends indication information 2 to the router under the condition that the preset condition is satisfied.

In some embodiments, the above-mentioned indication information 2 is also referred to as fourth indication information. The above-mentioned indication information 2 may be a Wi-Fi frame. In addition, the above-mentioned indication information 2 may be used to indicate the registration of the low-latency feature, and may also be referred to as indicating that the low-latency feature is enabled. The above-mentioned indication information 2 includes content for indicating the registration of the low-latency feature, and the content for indicating the registration of the low-latency feature may be stored in a reserved field of the Wi-Fi frame. For the structure of the above Wi-Fi frame, reference may be made to the Wi-Fi protocol. The above-mentioned Wi-Fi frames can be classified into multiple types, such as control frames, management frames, and data frames.

In this embodiment of the present application, the indication information 2 may be a control frame or a management frame, which is not limited.

According to the regulations in the Wi-Fi protocol, each type of Wi-Fi frame corresponds to multiple subtypes.

For example, the subtypes of the management frame may also include a Beacon frame, an Authentication request frame, an Authentication respond frame, an association request frame, an association respond frame, a Reserved frame, and the like. Refer to Table 1:

Table 1

As shown in Table 1, Subtype can take different values to indicate that the subtype of the management frame is Beacon frame, Authentication request frame, Authentication respond frame, association request frame, association respond frame, Probe request frame, Probe Response frame or reserved frame Which kind of frame in the management frame etc.

For example, when Type=00 and Subtype=0000, it indicates that the Wi-Fi frame is a management frame, and the corresponding subtype is an Association Request frame. When Type=00 and Subtype=0001, it indicates that the Wi-Fi frame is a management frame, and the corresponding subtype is an Association Response frame. When Type=00 and Subtype=1011, it indicates that the Wi-Fi frame is a management frame, and the corresponding subtype is an Authentication frame. When Type=00, Subtype=1000, it indicates that the Wi-Fi frame is a Beacon frame; when Type=00, Subtype=1111, it indicates that the Wi-Fi frame is a management frame, and the corresponding subtype is a reserved frame.

For another example, the subtype of the control frame may also include a Reserved frame, a Trigger frame, and the like. Refer to Table 2:

Table 2

As shown in Table 2, when Type=01 and Subtype=0000, it indicates that the Wi-Fi frame is a control frame, and the corresponding subtype is a reserved frame. When Type=01 and Subtype=0001, it indicates that the Wi-Fi frame is a control frame, and the corresponding subtype is a reserved frame. When Type=01 and Subtype=0010, it indicates that the Wi-Fi frame is a control frame, and the corresponding subtype is a trigger frame, etc.

Of course, the control frame may also include other subtypes. For details, please refer to the regulations in the Wi-Fi protocol, which will not be repeated here.

Certainly, regardless of whether the indication information 2 is a control frame or a management frame, the content in the indication information 2 for indicating the registration of the low-latency feature may be in the corresponding frame entity.

Taking the indication information 2 as a management frame and the corresponding subtype as a reserved frame as an example, the content for indicating the registration of the low-latency feature may be stored in the reserved information element. The above-mentioned reserved information element is a reserved field of the management frame, and exists in the form of an information element (information element), and its element ID can refer to the Wi-Fi protocol. As shown in FIG. 8 , in the type field of the frame header 801 corresponding to the indication information 2, Type=00 and Subtype=1111. The frame entity 802 corresponding to the indication information 2 includes the reserved information element, in the information element:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0001, it is used to indicate low Delay feature registration. Understandably, the above-mentioned low-latency feature registration is one of the related matters of the low-latency feature.

That is, Frame Body.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0001, which are the contents of the indication information 2 used to indicate the registration of the low-latency feature.

In addition, Frame Body.dataByte[4-7] is a reserved field.

Of course, the detection header 801 may also include: duration, address field, station MAC address (BSSID), sequence control field (sequence Control), and high throughput control (HT Control), which is no longer required. Repeat.

Taking the indication information 2 as a control frame and the corresponding subtype as a reserved frame as an example, the content for indicating the registration of the low-latency feature may be stored in the frame entity 902 . As shown in FIG. 9 , in the type field of the frame header 901 corresponding to the indication information 2, Type=01, Subtype=0000. In the frame entity 902 corresponding to the indication information 2:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it is used to indicate low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0001, it is used to indicate low Delay feature registration. Understandably, the above-mentioned low-latency feature is registered as one of the related matters of the low-latency feature.

In addition, Frame Body.dataByte[4-7] is a reserved field.

S107, the router sends indication response information 2 to the mobile phone.

In some embodiments, the above-mentioned indication response information 2 is also referred to as fourth response information. The above-mentioned indication response information 2 is used to indicate the result of the feature registration. The above-mentioned indication response information 2 carries the content used to indicate the characteristic registration result. The above-mentioned indication response information 2 may also be a Wi-Fi frame, such as a control frame or a management frame. The above-mentioned content used to indicate the characteristic registration result may also be stored in the reserved field of the Wi-Fi frame.

The feature registration result may include feature registration success and feature registration failure.

Exemplarily, when the router disables the low-latency feature, the router may determine that the feature registration result corresponding to the mobile phone is the feature registration failure.

For another example, when the router determines that the mobile phone does not have the conditions to use the low-latency feature service, the router may determine that the feature registration result corresponding to the mobile phone is the feature registration failure. For example, when the mobile phone is included in the list of devices that cannot use the low-latency service by the router, the router may determine that the feature registration result corresponding to the mobile phone is the feature registration failure.

For another example, when the router enables the low-latency feature and the router determines that the mobile phone has the conditions to use the low-latency feature service, it may be determined that the feature registration result corresponding to the mobile phone is successful feature registration.

Corresponding to the characteristic registration result, the indication response information 2 is also divided into registration success information and registration failure information.

In some embodiments, if the feature registration result is that the feature registration is successful, the router may send registration success information to the mobile phone.

Taking the registration success information as a management frame and the corresponding subtype as a reserved frame as an example, the content used to indicate the registration of the low-latency feature may be stored in the reserved information element. In the type field of the frame header corresponding to the registration success information, Type=00, Subtype=1111. The reserved information elements of the frame entity corresponding to the registration success information:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0002, it indicates low latency Feature registration result feedback. Understandably, the above-mentioned feedback of the registration result of the low-latency feature is also one of the related matters of the low-latency feature.

Frame Body.dataByte[4-5], used to indicate the actual registration result, for example, FrameBody.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0002 and FrameBody.dataByte[4-5 ] is x0000, indicating that the low-latency feature is successfully registered.

That is, Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0002, and Frame Body.dataByte[4-5] is x0000, which are used in the registration success information to indicate the result of feature registration content.

In addition, Frame Body.dataByte[6-7] is a reserved field.

In other embodiments, when the registration success information is a control frame and the corresponding subtype is a reserved frame, Type=01 and Subtype=0000 in the type field of the frame header corresponding to the registration success information. The registration success information belonging to the control frame is the same as the frame entity of the registration success information belonging to the management frame, and details are not repeated here.

In some embodiments, when the feature registration result is that the feature registration fails, the router sends registration failure information to the mobile phone.

The difference between the above registration failure information and registration success information may include: the values of FrameBody.dataByte[4-5] in the frame entity are different. Exemplarily, if Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0002, and Frame Body.dataByte[4-5] is x0000, it is used to indicate the characteristics of low latency characteristics If the registration is successful, then Frame Body.dataByte[0-1] is 0x0001, FrameBody.dataByte[2-3] is 0x0002, and Frame Body.dataByte[4-5] is x0001, which is used to indicate that the feature registration of the low-latency feature fails. .

That is, Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0002, and Frame Body.dataByte[4-5] is x0001, which are used in the registration failure information to indicate the result of feature registration content.

In some other possible embodiments, the above-mentioned registration failure information may further carry the reason for the failure of feature registration. In this way, the difference between the registration failure information and the registration success information may further include: Frame Body.dataByte[6-7] in the frame entity of the registration failure information, which is used to carry the failure cause error code. For example, when the pre-agreed failure cause error code is 0, it indicates that the registration failed due to feature shutdown. For another example, when the pre-agreed failure cause error code is 1, it indicates that the registration fails due to other reasons. Thus, Frame Body.dataByte[0-1] is 0x0001, FrameBody.dataByte[2-3] is 0x0002, Frame Body.dataByte[4-5] is x0001 and FrameBody.dataByte[6-7] is 0x0000, indicating low The reason for the delay feature registration failure is that the feature is disabled.

In addition, in some embodiments, the registration failure information may be a management frame, and Type=00 and Subtype=1111 in the type field of the corresponding frame header. In other embodiments, the registration failure information may also be a control frame, and Type=01 and Subtype=0000 in the type field of the corresponding frame header.

In some embodiments, through the above-mentioned air interface interaction from S101 to S107, if the registration of the low-latency feature of the mobile phone is successful, the router can preferentially create a PDU session for the mobile phone. Avoid delays caused by untimely creation of PDU sessions.

Of course, the method shown in FIG. 6 is only an example, which shows that the method provided by the embodiment of the present application is applied in a scenario where a mobile phone passively accesses a router. In other possible embodiments, the method provided by the embodiment of the present application may also be applied to a scenario in which a mobile phone actively accesses a router. That is, as shown in FIG. 10 , the method provided by the embodiment of the present application further includes:

S201, the mobile phone sends a detection request to the router.

In some embodiments, the above probe request may be a Probe request frame, which also belongs to a management frame in the Wi-Fi frame. Exemplarily, when Type=00 and Subtype=0100, the Wi-Fi frame is also the Probe request frame. For the frame header and frame entity of the Proberequest frame, reference may be made to the Wi-Fi protocol, which will not be repeated here.

S202, in response to the probe request, the router sends a probe response to the mobile phone.

In some embodiments, the router sends a probe response to the cell phone in response to the probe request sent by the cell phone. The above-mentioned probe response may be a Probe Respons frame, which also belongs to a management frame in a Wi-Fi frame. Exemplarily, when Type=00 and Subtype=0101, the Wi-Fi frame is also the Probe Respons frame. Of course, unlike the regular Probe Respons frame, the Probe Respons frame can indicate whether the router supports various features. For example, the Probe Respons frame can indicate whether the router supports the low-latency feature. In some embodiments, the Probe Respons frame sent by the router to the mobile phone may carry characteristic information of the router, such as low-latency characteristic information. The above feature information may be used to indicate whether the router supports various features. In some embodiments, the aforementioned characteristic information may be contained in a vendor-specific field (vendor-specific) in the Probe Respons frame. For the principle of configuring the feature information in the vendor-specific of the Probe Respons frame, reference may be made to configuring the feature information in the vendor-specific of the Beacon frame in the foregoing embodiment. It is not repeated here.

Similarly, the mobile phone can determine whether the router supports the low-latency feature according to the "vendor-specific" field of the Probe Respons frame. For example, identify the value of Value[4:5] from the vendor-specific whose element ID is 221 and Value[2:3] is 0x0001 in the Probe Respons frame. If Value[4:5] is 0x0001, then The mobile phone confirms that the router supports the low-latency feature. If the Value[4:5] value is 0x0000, the mobile phone confirms that the router does not support the low-latency feature.

S203, the mobile phone sends an identity authentication request to the router in response to the detection response.

S204, the router sends an identity authentication response to the mobile phone.

S205, the mobile phone initiates an association request to the router.

S206, the router sends an association request to the mobile phone.

S207, the mobile phone sends indication information 2 to the router under the condition that the preset condition is satisfied.

S208, the router sends indication response information 2 to the mobile phone.

It can be understood that, for the principles of the above S203 to S208, reference may be made to S102 to S107 in the method shown in FIG. 6 , which will not be repeated here.

In some embodiments, through the above-mentioned air interface interaction from S201 to S208, if the feature registration result is that the feature registration is successful, the router may preferentially create a PDU session for the mobile phone. Avoid delays caused by untimely creation of PDU sessions.

In other embodiments, after the feature of the low-latency feature is successfully registered, the mobile phone can also apply for a low-latency service (also called activation of the low-latency feature) according to whether a real-time application is running. When the low-latency service request is successful, the air interface resources are preferentially scheduled for the mobile phone. In this way, low-latency services that meet actual business requirements can be realized.

That is, in some embodiments, after the foregoing S107 or S208, as shown in FIG. 11 , the foregoing method may further include:

S301, when the mobile phone satisfies the set condition, the mobile phone sends instruction information 1 to the router.

Exemplarily, the above-mentioned manners for satisfying the set conditions include a combination of one or more of the following:

(1) The mobile phone starts the first application. That is, when the first application is started, the mobile phone may be triggered to send the corresponding indication information 1 to the router.

(2) The power of the mobile phone is lower than the preset power value. At this time, for the mobile phone, waiting for data transmission will increase the power consumption. When the power of the mobile phone is low, it can also be considered that the mobile phone has a low-latency transmission requirement at this time, and the mobile phone can send the corresponding instruction information to the router 1.

(3) The temperature of the mobile phone exceeds the preset temperature, etc.

In some embodiments, the above-mentioned indication information 1 may include the identifier of the first application. Wherein, the above-mentioned first application may be an application program requiring high timeliness of data transmission. For example, a real-time online game in a mobile phone that requires high timeliness of data transmission may be the first application. The above-mentioned indication information 1 may be used to instruct to apply for a low-latency service for the first application, so as to improve the transmission timeliness of the service data of the first application.

The above-mentioned indication information 1 may further include an identifier indicating to apply for a low-latency service.

In some embodiments, the above-mentioned indication information 1 may be a control frame in a Wi-Fi frame, or a management frame in a Wi-Fi frame. The identifier of the first application and the identifier indicating the application for the low-latency service may be included in the frame entity of the Wi-Fi frame. In this way, the mobile phone sends the instruction information 1 to the router, and can apply to increase the priority of the first application in the router, speed up the timeliness of data transmission of the first application, and meet the actual operation requirements.

Taking the indication information 1 being a management frame and the corresponding subtype being a reserved frame as an example, the identifier of the first application and the identifier indicating the application for the low-latency service are stored in the reserved information element. As shown in FIG. 12 , in the type field of the frame header 1201 corresponding to the indication information 1, Type=00 and Subtype=1111. The reserved information element in the frame entity 1202 corresponding to the indication information 1:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0003, it indicates that the application is low Delayed service. Understandably, the above-mentioned low-latency service is a service that can be provided by a device with a low-latency feature. Therefore, applying for a low-latency service is also one of the matters related to the low-latency feature.

In addition, Frame Body.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0003, which are the identifiers in the indication information 1 indicating to apply for the low-latency service.

Frame Body.dataByte[4-7], used to indicate the communication IP used by the first application. The above-mentioned communication IP belongs to one of the identifiers of the first application, and is used by the router to identify the first application. For example, Frame Body.dataByte[4-7] can be 0x123456789a.

Frame Body.dataByte[8-9], used to indicate the port used by the first application. The above-mentioned port also belongs to one of the identifiers of the first application, and the data sent by the first application can be quickly identified through the cooperation between the communication IP and the port. For example, Frame Body.dataByte[8-9] can be 0x1234.

In addition, Frame Body.dataByte[10-13] is a reserved field.

It should be noted that when the indication information 1 is a control frame, as shown in FIG. 13 . The indication information 1 at this time is compared with the indication information 1 shown in FIG. 12 in that the type fields of the frame headers of the two are different. That is, the frame header 1301 of the indication information 1 shown in FIG. 13: Type=01, Subtype=0000. The included first application identifier and the identifier indicating the application for the low-latency service are both stored in the frame entity 1302 shown in FIG. 13 , which will not be repeated here.

S302, the router feeds back indication response information 1 to the mobile phone.

In some embodiments, the indication response information 1 is also referred to as the first response information. The above-mentioned indication response information 1 carries an identifier indicating the result of the low-latency service application. The above-mentioned indication response information 1 may be a Wi-Fi frame, for example, a control frame or a management frame. The above-mentioned identifier indicating the result of the low-latency service application may also be stored in the reserved field of the Wi-Fi frame.

In addition, the low-latency service application result may include application success and application failure.

Exemplarily, in the case that the service of the router is turned off, the router may determine that the application result of the low-latency service corresponding to the mobile phone is an application failure.

For another example, when the number of applications currently providing the low-latency service by the router exceeds a preset value, the router may determine that the application result for the low-latency service corresponding to the mobile phone is an application failure.

For another example, in the case that the router also has the ability to provide a low-latency service, and the service is not turned off, the router may determine that the application result of the low-latency service corresponding to the mobile phone is successful.

Corresponding to the low-latency service application result, the above-mentioned indication response information 1 may also include application success information and application failure information.

In some embodiments, when the application for the low-latency service for the first application is successful, the router will not only increase the transmission priority of the service data of the first application (for example, called third service data), but will also send the service data to the mobile phone. Send application success message.

Taking the application success information as a management frame and the corresponding subtype as a reserved frame as an example, an identifier indicating the result of the low-latency service application is included in the reserved information element. In the type field of the frame header corresponding to the application success information, Type=00, Subtype=1111. The information element is reserved in the frame entity corresponding to the successful application information:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0004, it indicates low latency Service application result feedback. Understandably, the above-mentioned feedback of the low-latency service application result is also one of the matters related to the low-latency feature.

Frame Body.dataByte[4-5], used to indicate the actual registration result, for example, FrameBody.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004 and FrameBody.dataByte[4-5 ] is x0000, indicating that the low-latency service application is successful.

Understandably, the above Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004, and Frame Body.dataByte[4-5] is x0000, that is, the application success information indicates low latency The identification of the service request result.

In addition, Frame Body.dataByte[6-7] is a reserved field.

In other embodiments, when the application success information is a control frame and the corresponding subtype is a reserved frame, Type=01 and Subtype=0000 in the type field of the frame header corresponding to the application success information. An identifier indicating the result of the low-latency service application is included in the frame entity, for example, Frame Body.dataByte[0-1]: 0x0001. Frame Body.dataByte[2-3]: 0x0004. Frame Body.dataByte[4-5]: x0000. Among them, Frame Body.dataByte[0-1]: 0x0001, Frame Body.dataByte[2-3]: 0x0004 indicate the result of the low-latency feature service application. FrameBody.dataByte[4-5]: x0000 indicates that the application is successful.

In some embodiments, when the low-latency service application for the first application fails, the router sends application failure information to the mobile phone.

The difference between the above application failure information and application success information may include: the values of FrameBody.dataByte[4-5] in the frame entity are different. Exemplarily, if Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004, and Frame Body.dataByte[4-5] is x0000, indicating that the low-latency service application is successful, then Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004, and Frame Body.dataByte[4-5] is x0001, indicating that the low-latency service application failed.

Similarly, the above Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004, and Frame Body.dataByte[4-5] is x0001, which is also the indication of low-latency service application in the application failure information The ID of the result.

In some other possible embodiments, the above-mentioned application failure information may also carry the reason for the failure of the service application. In this way, the difference between the application failure information and the application success information may further include: Frame Body.dataByte[6-7] in the frame entity of the application failure information, which is used to carry the failure cause error code. For example, when the pre-agreed failure cause error code is 0, it corresponds to the application failure caused by the service shutdown. For another example, when the pre-agreed failure reason error code is 1, the application fails due to other reasons. In this way, Frame Body.dataByte[0-1] is 0x0001, Frame Body.dataByte[2-3] is 0x0004, Frame Body.dataByte[4-5] is x0001 and Frame Body.dataByte[6-7] is 0x0000, Indicates that the low-latency service application failed because the service was shut down.

In addition, in some embodiments, the application failure information may be a management frame, and Type=00 and Subtype=1111 in the type field of the corresponding frame header. In other embodiments, the application failure information may also be a management frame, and Type=01 and Subtype=0000 in the type field of the corresponding frame header.

It can be seen that with the cooperation of S301 and S302, if the mobile phone successfully applies for the low-latency service for the first application, it can identify the service data of the first application according to the communication IP and port obtained from the instruction information 1, such as called Third business data. and store it in the low-latency queue (such as the first queue), so that when the air interface resources (also known as transmission resources) in the router are idle, the air interface resources are preferentially used to buffer the data in the low-latency queue. issue. Therefore, the data transmission time limit is improved for the first application, and the user experience is enhanced. During this period, the business data generated by the non-real-time application running in the mobile phone, such as the second application, can be called the fifth business data, which can be prioritized according to enhanced distributed channel access (EDCA) It is sent through the high-level mechanism to avoid affecting the service data transmission of other devices. In addition, the service data of other devices, such as the fourth service data, can also be sent according to the EDCA priority mechanism. In some embodiments, the above-mentioned second application may also refer to all applications in the mobile phone that have not applied for the low-latency service.

In some embodiments, the above-mentioned low-latency queues are different from background traffic (BG) queues, best effort traffic (BE) queues, video traffic (VI) queues, and audio queues provided by EDCA Flow (Voice traffic, VO) queue. The above-mentioned BG queue, BE queue, VI queue, and VO queue are called the second queue. For business data sent by applications that have not applied for low-latency services, they can be stored in the BE queue, BG queue, VO queue, and VI queue according to the traditional EDCA priority. In this way, when there is data in the low-latency queue, the data in it is sent first. When there is no data in the low-latency queue, the queue that needs to occupy air interface resources for data transmission is selected from the BE queue, BG queue, VO queue, and VI queue according to the EDCA priority rules.

The above-mentioned "store the service data in the second queue. After the service data in the first queue is sent, use the idle air interface resources to send the process of sending the data stored in the second queue" may be referred to as using the first preset mode to send business data.

The above-mentioned "storing the service data in the first queue, and using idle air interface resources to send the data stored in the first queue" may be referred to as using the second preset mode to send the service data.

In other embodiments, the above-mentioned sending of the service data by using the second preset manner may also be: when there are idle air interface resources, the service data is directly sent out by using the air interface resources without waiting. The above-mentioned sending of the service data by using the first preset mode may also be: in the case where the service data sent by the second preset mode is not required, the service data is sent out in sequence according to the received service data, or the service data is sent out according to the order of the received service data. The corresponding service priorities are sent out in sequence.

It can be understood that the transmission priority of the second preset mode is higher than the transmission priority of the first preset mode. For example, when the third service data sent by the mobile phone is transmitted using the second preset method, and the fourth service data sent by the tablet computer is transmitted using the first preset method, the third service data is preferentially sent over the fourth service data. business data.

Of course, in other embodiments, after passing through S105 or S206, that is, after completing the association between the mobile phone and the router, the process can directly enter S301. Understandably, in the case that all Wi-Fi devices support the low-latency feature, there is no need to register the low-latency feature, that is, after S105 or S206, skip S106 and S207, and the process enters S301. In this way, after the router determines to provide a low-latency service for the first application of the mobile phone, it preferentially creates a PDU session for the mobile phone, and preferentially sends the service data of the first application to the Wi-Fi network side. If the router determines to provide the low-latency service for the first application of the mobile phone, and the PDU session corresponding to the mobile phone has been established, the service data of the first application is preferentially sent to the Wi-Fi network side.

In addition, when the mobile phone transmits data through the router, the router can also recommend the mobile phone to select the network to use according to the real-time network status of the Wi-Fi network side. That is, in some embodiments, as shown in FIG. 14 , the above data transmission method may further include:

S401 , when the router detects a network instability factor, it sends instruction information 3 to the mobile phone.

In some embodiments, the above-mentioned indication information 3 is also referred to as second indication information. The above-mentioned network instability factors can be congestion on the wired side of the router, strong interference in the environment, and the Wi-Fi carrier is affected by the radar, and the carrier needs to be switched. Exemplarily, when the router detects the source-end suppression packet, it may be determined that congestion occurs on the wired side of the router. For another example, the router may scan the wireless signal strength of the environment in which it is located, and when the scanned wireless signal strength exceeds a preset threshold, determine that there is strong interference in the environment. The above-mentioned preset threshold may be a signal strength threshold, which is used to measure whether a wireless signal existing in the environment is an interference signal. The above-mentioned preset threshold can be obtained by testing in a strong interference environment in advance. In other embodiments, the above-mentioned preset threshold may be an empirical value configured by a user.

In some embodiments, the above-mentioned indication information 3 may be a Wi-Fi frame. The indication information 3 can be used to instruct to switch the communication channel. In some embodiments, the indication information 3 includes an identifier for instructing to switch the communication channel. The above-mentioned identifier for instructing to switch the communication channel is stored in a reserved bit in the Wi-Fi frame. In this way, after the mobile phone receives the indication information 3, it can autonomously switch to other communication channels, such as the mobile data channel of the operator or the communication channel provided by other routes, to replace the current Wi-Fi communication channel. Thereby, the data transmission time of the first application in the mobile phone due to unstable factors in the current Wi-Fi network is improved. Further guarantee the timeliness of data transmission of mobile phones. In addition, compared to switching to other communication channels after the mobile phone is completely disconnected from the router, channel switching is more timely.

In addition, the indication information 3 may also be a management frame or a control frame.

Taking the indication information 3 as a management frame and the corresponding subtype as a reserved frame as an example, the identifier for instructing the switching of the communication channel is included in the reserved information element. As shown in FIG. 15 , in the type field of the frame header 1501 corresponding to the indication information 3, Type=00 and Subtype=1111. The reserved information element in the frame entity corresponding to the indication information 3:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate that the network service quality provided by the router is not good and the channel needs to be switched. For example, when Frame Body.dataByte[2-3] is 0x0010, it indicates that it is recommended to switch the channel. In other words, Frame Body.dataByte[2-3] is 0x0010, which is an identifier in the indication information 3 used to instruct to switch the communication channel.

In addition, Frame Body.dataByte[4-7] is a reserved field.

In addition, when the indication information 3 is a control frame, the corresponding Type=01 and Subtype=0000. The above-mentioned identifier indicating the switching of the communication channel is contained in the frame entity, for example, Frame Body.dataByte[0-1]: 0x0001. FrameBody.dataByte[2-3]: 0x0010. Frame Body.dataByte[4-5]: x0000. Among them, FrameBody.dataByte[0-1]: 0x0001, Frame Body.dataByte[2-3]: 0x0010 are identifiers indicating switching of communication channels.

S402, the mobile phone sends indication response information 3 to the router.

In some embodiments, the indication response information 3 is also referred to as the second response information. The above-mentioned indication response information 3 carries the content indicating the channel switching result. The above-mentioned indication response information 3 may also be a Wi-Fi frame, for example, a control frame or a management frame. The above content indicating the channel switching result may also be stored in the frame entity of the Wi-Fi frame.

In addition, the channel switching result may include channel switching success and channel switching failure. Correspondingly, the indication response information 3 may also include handover success information and handover failure information.

In some embodiments, when the mobile phone is successfully switched to other communication channels, that is, the mobile phone enables other communication channels to send the service data of the first application. The mobile phone sends a handover success message to the router.

Taking the switching success information as a management frame and the corresponding subtype as a reserved frame as an example, the content indicating the channel switching result is included in the reserved information element. In the type field of the frame header corresponding to the handover success information, Type=00, Subtype=1111. The reserved information element in the frame entity corresponding to the handover success information:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3], used to indicate the feedback for channel switching, for example, FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0011.

Frame Body.dataByte[4-5] is used to indicate the actual switching result. For example, when FrameBody.dataByte[2-3] is 0x0011 and Frame Body.dataByte[4-5] is x0000, it indicates that the channel is switched successfully.

That is, Frame Body.dataByte[2-3] is 0x0011 and Frame Body.dataByte[4-5] is x0000, which is the content indicating the channel switching result in the switching success information.

In addition, Frame Body.dataByte[6-7] is a reserved field.

In other embodiments, when the switching success information is a control frame and the corresponding subtype is a reserved frame, Type=01 and Subtype=0000 in the type field of the frame header corresponding to the switching success information. The content indicating the channel switching result is contained in the frame entity, for example, the frame entity includes Frame Body.dataByte[0-1]: 0x0001. Frame Body.dataByte[2-3]: 0x0011. Frame Body.dataByte[4-5]: x0000.

In some embodiments, when the mobile phone fails to switch to another communication channel, the router will send the handover failure information to the mobile phone.

The difference between the above handover failure information and handover success information may include: the values of FrameBody.dataByte[4-5] in the frame entity are different. Exemplarily, if Frame Body.dataByte[2-3] is 0x0011 and Frame Body.dataByte[4-5] is x0000, indicating that the channel switching is successful, then Frame Body.dataByte[2-3] is 0x0011 and Frame Body. If dataByte[4-5] is x0001, it indicates that the channel switching fails.

That is, Frame Body.dataByte[2-3] is 0x0011 and Frame Body.dataByte[4-5] is x0001, which is the content indicating the channel switching result in the switching failure information.

In some other possible embodiments, the above-mentioned switching failure information may also carry the reason for the channel switching failure. In this way, the difference between the handover failure information and the handover success information may further include: Frame Body.dataByte[6-7] in the frame entity of the handover failure information, which is used to carry the failure cause error code. For example, when the pre-agreed failure cause error code is 0, the indication information error causes the handover failure. For another example, when the pre-agreed failure cause error code is 1, it indicates that the handover fails due to other reasons. In this way, Frame Body.dataByte[2-3] is 0x0011, Frame Body.dataByte[4-5] is x0001, and Frame Body.dataByte[6-7] is 0x0000, indicating that the reason for the channel switching failure is an information error.

In addition, in some embodiments, the information failure information may be a management frame, and Type=00 and Subtype=1111 in the type field of the corresponding frame header. In other embodiments, the information failure information may also be a management frame, and Type=01 and Subtype=0000 in the type field of the corresponding frame header.

In some embodiments, after receiving the handover success information sent by the mobile phone, if the router detects that the network is back to normal, for example, the network instability factor disappears, the router sends indication information 4, also referred to as the third indication information, to the mobile phone, It is used to instruct the mobile phone to use the communication channel provided by the router, that is, to send the service data of the first application by using the communication channel provided by the router. In some embodiments, the above-mentioned indication information 4 may be a control frame in a Wi-Fi frame, or a management frame in a Wi-Fi frame.

Take the indication information 4 as a management frame and the corresponding subtype as a reserved frame as an example. In the type field of the frame header corresponding to the indication information 4, Type=00, Subtype=1111. The reserved information element in the frame entity corresponding to the indication information 4:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3], which can be used to indicate the restoration of network services provided by the router. Exemplarily, Frame Body.dataByte[2-3] is 0x0012, indicating that the network service provided by the router is restored.

In addition, Frame Body.dataByte[4-7] is a reserved field.

When the indication information 4 is a control frame, Type=01 and Subtype=0000 in the type field of the corresponding frame header. The corresponding frame entity can be: Frame Body.dataByte[0-1]: 0x0001. Frame Body.dataByte[2-3]: 0x0012. In addition, Frame Body.dataByte[4-7] is a reserved field.

In some embodiments, the router instructs the mobile phone to switch the communication channel, which may be for the mobile phone that has activated the low-latency feature, that is, the mobile phone that has applied for the low-latency service for the first application. In this way, the low-latency service provided for the first application in the embodiment of the present application can ensure the timeliness of data transmission of the first application. Even if the network service quality provided by the router is poor, it can effectively and timely ensure the transmission of data.

Of course, the ability of routers to provide low-latency services is limited. After there are multiple first applications that enable the low-latency service, a new first application that applies for starting the low-latency service is prone to application failure. In order to improve the above problem, in the case where the first application does not use the low-latency service, the low-latency service corresponding to the first application may also be closed in time. Therefore, the method provided by the embodiment of the present application may further include: the mobile phone sends instruction information 5 to the router, which is used to instruct to close the low-latency service for the first application.

In some embodiments, when the mobile phone does not meet the set conditions, indication information 5 may be sent to the router.

Exemplarily, the manner in which the set condition is not met may include a combination of one or more of the following:

(1) Close the first application on the mobile phone. (2) The temperature of the mobile phone does not exceed the preset temperature. (3) The power of the mobile phone exceeds the preset power.

The above-mentioned indication information 5 may be a control frame in the Wi-Fi frame, or may be a management frame in the Wi-Fi frame. The identifier of the first application and the identifier indicating that the low-latency service is turned off may be included in the Wi-Fi frame reservation field. In this way, after receiving the indication information 5, the router does not preferentially send the service data of the first application.

Take the indication information 5 as a management frame and the corresponding subtype as a reserved frame as an example. In the type field of the frame header corresponding to the indication information 5, Type=00, Subtype=1111. The reserved information element in the frame entity corresponding to the indication information 5:

Frame Body.dataByte[0-1] is used to enumerate characteristics. For example, when Frame Body.dataByte[0-1] is 0x0001, it indicates low latency characteristics.

Frame Body.dataByte[2-3] is used to indicate the related matters of the enumerated characteristics. For example, when FrameBody.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0005, it indicates that the application is closed Low latency service. Understandably, the application for closing the low-latency service is also one of the related matters of the low-latency feature.

In addition, Frame Body.dataByte[0-1] is 0x0001 and Frame Body.dataByte[2-3] is 0x0005, which are the identifiers in the indication information 5 indicating that the low-latency service is turned off.

Frame Body.dataByte[4-7], used to indicate the communication IP used by the first application. The above-mentioned communication IP belongs to one of the identifiers of the first application, and is used by the router to identify the first application. For example, Frame Body.dataByte[4-7] can be 0x123456789a.

Frame Body.dataByte[8-9], used to indicate the port used by the first application. The above-mentioned port also belongs to one of the identifiers of the first application, and the data sent by the first application can be quickly identified through the cooperation between the communication IP and the port. For example, Frame Body.dataByte[8-9] can be 0x1234.

In addition, Frame Body.dataByte[10-13] is a reserved field.

It should be noted that when the indication information 5 is a control frame, the Type=01 and Subtype=0000 of the indication information 5, the identifier of the above-mentioned first application and the identifier indicating the closing of the low-latency service are included in the frame entity, which is no longer required. Repeat.

In this way, after receiving the indication information 5, the router can determine the low-latency service of which application program needs to be shut down. Avoid affecting other first apps.

In the above embodiment, the device 1 is a mobile phone and the device 2 is a router as an example. The methods provided by the embodiments of the present application may also be applied in other scenarios involving Wi-Fi.

As shown in Figure 16, device 1 is a handle that supports Wi-Fi direct connection, and device 2 is a smart TV that supports Wi-Fi direct connection. The handle is connected to the smart TV through Wi-Fi technology. When the smart TV starts a real-time online game, the handle can receive the user's operation and convert it into game interaction data. In addition, the handle also needs to send game interaction data to the corresponding game server through the smart TV. After receiving the game interaction data, the game server determines the displayed game screen and transmits it to the smart TV for display. During this process, the controller has high requirements on the timeliness of sending game interaction data. Of course, a smart TV can also be connected to other devices that support Wi-Fi technology, for example, a tablet computer can be connected to a smart TV, access a video server through the smart TV, find videos and play them in a small window of the smart TV. Although smart TVs solve the problem of multiple device access and use by dividing the display area, the air interface resources provided by smart TVs are more limited, and multiple access devices (such as handles or tablet computers) need to be connected to corresponding devices through smart computers. There will be more serious delays when data interaction is performed on the server of the server.

Therefore, in a scenario where the device 1 is a handle supporting the Wi-Fi technology, and the device 2 is a smart TV supporting the Wi-Fi technology, the data transmission method provided by the embodiment of the present application is also applicable. That is, the handle is equivalent to the mobile phone in the foregoing embodiment, and the smart TV is equivalent to the router in the foregoing embodiment. After the handle is connected to the smart TV, the low-latency feature can be registered. And after the real-time online game starts, for example, receiving the designated key on the user's operating handle, the handle applies to the smart TV for low-latency service. Thereby ensuring the timeliness of data transmission of the handle. Of course, other devices connected to the smart TV can also apply for low-latency feature registration and low-latency service.
