technical field

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

Background technique

In recent years, various terminal devices have been popularized, bringing great convenience to users. Two terminal devices can communicate to realize data exchange and exchange. For example, a smart watch can collect the user's health data and send the health data to the mobile phone.

In the prior art, a communication link may be established between two terminal devices, and then one terminal device transmits data to another terminal device or based on the communication link. However, since the communication link between the two terminal devices is strictly limited by the hardware and software conditions of the two terminal devices, there is often a bottleneck in the communication link and the transmission efficiency is low.

SUMMARY OF THE INVENTION

In view of this, the present application provides a data transmission method and a terminal device, thereby improving the efficiency of transmitting the first data from the first terminal device to the second terminal.

In order to achieve the above purpose, in a first aspect, an embodiment of the present application provides a data transmission method, including:

The first terminal determines to transmit the first data through the first link with the second terminal;

If the first terminal determines that the transmission speed of the first link is lower than the average transmission speed of the second link and the third link, then the first terminal passes through the third link and the second link. the link sends at least part of the first data to the second terminal;

The second link is a communication link between a third terminal and the second terminal, and the third link is a communication link between the first terminal and the third terminal.

It should be noted that the terminal information may be used to describe the identity of the terminal device, so that other terminal devices can establish a communication link with the terminal device corresponding to the terminal information based on the terminal information. For example, the terminal information may include a device identification, and may also include a password of the terminal device. Optionally, the terminal information may include at least one of a Bluetooth name and a service set identifier (SSID).

In this embodiment of the present application, when the first terminal determines to send the first data through the first link with the second terminal, if the transmission speed of the first link is lower than that between the second terminal and the third terminal The average transmission speed of the second link and the third link between the first terminal and the third terminal, the first terminal can transmit the first data to the second terminal via the third link and the second link. at least part of the data. Since the transmission speed of the first link is lower than the average transmission speed of the second link and the third link, the time taken by the first terminal to transmit the data to the second terminal through the second link and the third link, It is less than the time taken by the first terminal to transmit the data to the second terminal through the first link. That is, the data transmission between the first terminal and the second terminal is no longer completely limited by the hardware conditions or software conditions of the first terminal and the second terminal, and the first terminal can select the transmission through other third terminals. A faster communication link is used to send at least part of the first data to the second terminal, thereby reducing the time period for sending the first data to the second terminal to a certain extent or to the maximum extent, and improving transmission efficiency.

Optionally, if the first terminal determines that the transmission speed of the first link is smaller than the average transmission speed of the second link and the third link, then the first terminal passes the third link. Before the link and the second link send at least part of the first data to the second terminal, the method further includes:

The first terminal sends a first selection notification to the second terminal, where the first selection notification is used to notify the second terminal that the second terminal is among the M fourth terminals included in the terminal set associated with the first terminal Determine the third terminal, M≥1 and M is a positive integer;

The first terminal receives the terminal information of the third terminal sent by the second terminal according to the first selection notification.

The second terminal may acquire the transmission speed of the first link, the transmission speed between the eleventh link between the second terminal and the fourth terminal, and the transmission speed of the twelfth link between the first terminal and the fourth terminal If the average transmission speed of the eleventh link and the twelfth link is greater than the transmission speed of the first link, the second terminal may determine the fourth terminal as the third terminal, and accordingly, The second terminal may determine the eleventh link with the fourth terminal as the second link, and the twelfth link between the first terminal and the fourth terminal as the third link. In some embodiments, if there is more than one fourth terminal, and the average transmission speed of the eleventh link and the twelfth link corresponding to the fourth terminal is greater than the transmission speed of the first link, the second terminal may According to the order of the average transmission speed of the eleventh link and the twelfth link from high to low, select N fourth terminals from more than one fourth terminal as the third terminals, M≥N≥1 and N is positive integer.

The transmission speed of the link and the transmission speed of the second link are determined, the transmission speed of the eleventh link can be obtained by detecting the eleventh link by the second terminal or the fourth terminal, and the transmission speed of the twelfth link The twelfth link may be detected by the fourth terminal or the first terminal. In some embodiments, the second terminal may acquire the transmission speed of the first link and the transmission speed of the eleventh link through detection, and acquire the transmission speed of the twelfth link from the first terminal or the fourth terminal.

The first speed threshold can be obtained by setting in advance, and when the difference between the maximum transmission speed indicated by the second preset communication protocol and the maximum transmission speed indicated by the first preset communication protocol is greater than the first speed threshold, The duration of transmitting the data through the twelfth link is negligible relative to the duration of transmitting the data through the eleventh link. Then, as long as the transmission speed of the eleventh link is greater than the transmission speed of the first link, it can be ensured that the first terminal transmits the data to the second terminal through the twelfth link and the eleventh link. It is less than the duration used by the first terminal to transmit the data to the second terminal through the first link. Therefore, the second terminal may only acquire the transmission speed of the first link and the transmission speed of the eleventh link, and determine the fourth terminal corresponding to the N eleventh links as the third terminal, and the N tenth links The transmission speed of one link is greater than the transmission speed of the first link. In some embodiments, on the basis of the above, the second terminal may determine N eleventh links in the order of transmission speed from high to low, and determine the fourth terminal corresponding to the N eleventh links is the third terminal, wherein the transmission speed of the N eleventh links may be greater than the transmission speed of the remaining eleven links. In addition, when the second terminal determines a fourth terminal as the third terminal, the eleventh link between the second terminal and the fourth terminal may be the second link, and the fourth terminal and the first terminal The twelfth link between can be the third link.

Similarly, if the eleventh link between the second terminal and any fourth terminal is a communication link based on the second preset communication protocol, the twelfth link between the first terminal and any fourth terminal is The link is a communication link based on the first preset communication protocol, and the second terminal may also only obtain the transmission speed of the first link and the transmission speed of the twelfth link, so as to convert the corresponding N twelfth links into The fourth terminal is determined as the third terminal, and the transmission speed of the N second links may be greater than the transmission speed of the first link.

In some embodiments, when receiving the association request, the fourth terminal may send first association prompt information to the user to prompt the user to be the resource pool of the first terminal, and notify the first terminal when receiving the user's confirmation operation. The terminal sends an association response. That is, before using the fourth terminal as the resource pool of the first terminal, the authorization of the user of the fourth terminal may be obtained to ensure the security of the fourth terminal and subsequent data transmission. Similarly, before storing the terminal information of the fourth terminal, the first terminal and the second terminal may also send the second associated prompt information to the user to prompt the user that the fourth terminal will be used as the resource pool of the first terminal, and the The terminal information of the fourth terminal is stored when the user confirms the operation. That is, the first terminal and the second terminal may also obtain user authorization before determining that the fourth terminal is used as the resource pool of the first terminal, so as to ensure the security of subsequent data transmission.

In order to facilitate understanding of the technical solutions in the embodiments of the present application, the following first introduces the application scenarios of the embodiments of the present application.

With the development of terminal technology, the types and numbers of terminal devices are increasing. These terminal devices can operate independently to realize certain functions, and can also communicate with other terminal devices to realize data intercommunication and exchange. For example, in some scenarios, the terminal device includes a mobile phone and a smart watch. The mobile phone can send a song to the smart watch, and the smart watch can receive and play the song; or, the mobile phone can send an image to the smart watch, and the smart watch can receive and play the song. The image is set as the dial background; alternatively, the smart watch can collect health data such as the user's walking steps, pulse or blood pressure, and send the health data to the mobile phone. Analyze processing, display processing results to users, etc. It can be seen that data transmission between terminal devices is a very important step.

Please refer to FIG. 2 , which is a data transmission system provided by an embodiment of the present application. The system may include a first terminal 210, a second terminal 220, and at least one third terminal 230 (three are shown in FIG. 2). The first terminal 210 and the third terminal 230 may be mobile phones, and the second terminal 220 may be a smart watch. The first terminal 210 , the second terminal 220 and the third terminal 230 may include more or less modules than the terminal device 100 shown in FIG. 1 . In some embodiments, the first terminal 210 and the third terminal 230 may include the wireless communication module 160 and the mobile communication module 150 , and the second terminal 220 may not include the mobile communication module 150 .

In some embodiments, when the first terminal 210 needs to send data to the second terminal 220, the first terminal 210 may establish a communication link with the second terminal 220, and then send the data to the second terminal through the communication link 220. It can be understood that, since the communication link is strictly limited by the hardware and software conditions of the first terminal 210 and the second terminal 220, there will also be a bottleneck in the transmission speed of the communication link. For example, the second terminal 220 can only Establish a Bluetooth communication link, then no matter whether the first terminal 210 can also establish other types of communication links other than the Bluetooth communication link, the first terminal 210 and the second terminal 220 can only transmit through the Bluetooth communication link data, resulting in inefficient data transmission. In addition, the transmission speed of the communication link between the first terminal 210 and the second terminal 220 may also be affected by the distance between the first terminal 210 and the second terminal 220. The greater the distance, the higher the transmission speed of the communication link. lower.

For example, the first terminal 210 and the second terminal 220 are provided with a Bluetooth module. The user takes a photo through the first terminal 210 and triggers the first terminal 210 to send the photo to the second terminal 220 through the Bluetooth module. The first terminal 210 establishes a Bluetooth protocol-based communication link (ie, a Bluetooth communication link) with the second terminal 220 through the Bluetooth module, and sends the photo to the second terminal 220 through the communication link. However, limited by the hardware conditions and software conditions of the Bluetooth modules in the first terminal 210 and the second terminal 220, the transmission speed of the communication link is relatively low. However, as the distance between the first terminal 210 and the second terminal 220 increases, the transmission speed will further decrease. In this case, obviously, there is no better remedy for the user or the first terminal 210 or the second terminal 220 . If the hardware conditions or software conditions are improved to improve the transmission speed, corresponding time is required, the current data transmission requirements of the first terminal 210 cannot be satisfied, and even if the hardware conditions or software conditions of the first terminal 210 or the second terminal 220 are improved , or remind the user to move the first terminal 210 close to the distance between the second terminal 220, the data transmission between the first terminal 210 and the second terminal 220 will still be strictly limited by the first terminal 210 and the second terminal 220, and it is difficult to The efficiency of sending data from the first terminal 210 to the second terminal 220 is effectively improved.

To solve this technical problem, an embodiment of the present application provides a data transmission method. When the first terminal 210 determines to send the first data through the first link with the second terminal 220, if the transmission speed of the first link is less than the second terminal 220 and the third terminal 230 link and the average transmission speed of the third link between the first terminal 210 and the third terminal 230, then the second link and the third link between the first terminal 210 and the third terminal 230 can be transmitted to The second terminal 220 transmits at least a part of the first data. Then the second terminal 220 may receive at least part of the first data.

Suppose the size of a certain data is 1, the transmission speed of the first link is x, the transmission speed of the second link is y, and the transmission speed of the third link is z. Because in practical applications, when the first terminal 210 transmits data to the third terminal 230 through the third link, the third terminal 230 can also transmit data to the second terminal 220 through the second link, that is, the actual data transmission process It may not be serial, therefore, the transmission speed h at which the first terminal 210 transmits the data to the second terminal 220 through the third link and the second link is greater than or equal to the average transmission speed of the second link and the third link yz/(y+z), and h is less than y or z. When the first terminal 210 transmits the data to the second terminal 220 through the second link and the third link, the transmission duration is less than or equal to (y+z)/yz, greater than 1/y or 1/z, and the transmission duration The duration infinitely approaches the larger of 1/y and 1/z. Then it can be seen that as long as the average transmission speed (y+z)/yz of the third link and the second link is greater than the transmission speed x of the first link, the first terminal 210 can pass the third link and the second link The time period used for transmitting the data to the second terminal 220 will be less than the time period used by the first terminal 210 for transmitting the data to the second terminal 220 through the first link. That is, the data transmission between the first terminal 210 and the second terminal 220 is no longer completely limited by the hardware conditions or software conditions of the first terminal 210 and the second terminal 220, and the first terminal 210 can pass other The third terminal 230 selects a communication link with a faster transmission speed to send at least part of the first data to the second terminal 220, so as to reduce the duration of sending the first data to the second terminal 220 to a certain extent or to a maximum extent, and improve the transmission efficiency.

In the above description, the first terminal 210 is used as a data sender, but it can be understood that, in practical applications, the first terminal 220 can also be used as a data receiver. Please continue to refer to FIG. 2 , in some embodiments, the data transmission system further includes a fifth terminal 240 and at least one sixth terminal 250 (only one is shown in FIG. 2 ). Similar to the foregoing, the fifth terminal 240 may also determine that the second data needs to be transmitted through the fourth link with the first terminal 210, and determine that the transmission speed of the fourth link is lower than that of the fifth link and the sixth link When the average transmission speed of The sixth link is a communication link between the fifth terminal 240 and the sixth terminal 250 .

Please continue to refer to FIG. 2, in some embodiments, the data transmission system may further include an eighth terminal 260, the communication link between the eighth terminal 260 and the second terminal 220 is a ninth link, and the eighth terminal 260 and the The communication link between a terminal 210 is the tenth communication link. The eighth terminal 260 acts as a data sender, the second terminal 220 acts as a data receiver, and the first terminal 210 acts as a data forwarder. When the eighth terminal 260 determines to send the third data to the second terminal 220, it can send the third data to the second terminal 220 through the ninth link and the first link in a manner similar to that of the first terminal 210 as the data sender. If at least part of the third data is sent, the aforementioned first data may be at least part of the third data received by the first terminal 210 from the eighth terminal 260 .

It should be noted that, each part of the functions of the first terminal 210 , the second terminal 220 , the third terminal 230 , the fifth terminal 240 , the sixth terminal 250 and the eighth terminal 260 can be run by the processors of the terminals respectively installed applications Program (application, APP) to achieve.

It should also be noted that this application only takes the above-mentioned FIG. 2 as an example to introduce the data transmission system provided in this application, but does not describe the first terminal 210 , the second terminal 220 , the third terminal 230 , the fifth terminal 240 , The types of the sixth terminal 250 and the eighth terminal 260 constitute any limitation. It can be understood that, in practical applications, the first terminal 210 , the second terminal 220 , the third terminal 230 , the fifth terminal 240 , the sixth terminal 250 and the eighth terminal 260 are not limited to mobile phones or smart watches.

It can be seen from the above FIG. 2 that the first terminal 210 needs to be associated with at least one third terminal 230, and then data can be transmitted to the second terminal 220 through the third terminal 230. Therefore, the following will also follow the sequence of terminal device association and data transmission. , the technical solutions of the present application will be described in detail with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

It should be understood that in other embodiments , the order of some steps in this method can be exchanged with each other according to actual needs, or some of the steps can also be omitted or deleted. The method includes the following steps:

S301, the first terminal sends an association request to a fourth terminal.

Wherein, the first terminal may obtain terminal information of the fourth terminal by searching or other methods, thereby establishing a communication link with the fourth terminal based on the terminal information, and sending an association request to the fourth terminal through the communication link. The association request may request to associate the fourth terminal with the first terminal, thereby setting the fourth terminal as the resource pool of the first terminal, and the association request may carry terminal information of the first terminal.

It should be noted that the terminal information may be used to describe the identity of the terminal device, so that other terminal devices can establish a communication link with the terminal device corresponding to the terminal information based on the terminal information. For example, s, the terminal information may include the device identification, and may also include the password of the terminal device. Optionally, the terminal information may include at least one of a Bluetooth name and an SSID.

It should also be noted that the resource pool may be used to provide the terminal device with data of another terminal device associated with the resource pool. For example, when the fourth terminal is the resource pool of the first terminal, the fourth terminal may be used to provide data from the first terminal to the second terminal.

S302, the fourth terminal sends an association response to the first terminal based on the association request.

The fourth terminal may send an association response to the fourth terminal party when receiving the association request, and the association response may carry terminal information of the fourth terminal.

In some embodiments, when receiving the association request, the fourth terminal may send first association prompt information to the user to prompt the user to be the resource pool of the first terminal, and notify the first terminal when receiving the user's confirmation operation. The terminal sends an association response. That is, before using the fourth terminal as the resource pool of the first terminal, the authorization of the user of the fourth terminal may be obtained to ensure the security of the fourth terminal and subsequent data transmission.

Before storing the terminal information of the fourth terminal, the first terminal and the second terminal may also send second associated prompt information to the user to remind the user that the fourth terminal will be used as the resource pool of the first terminal, and after receiving the user's The terminal information of the fourth terminal is stored when the operation is confirmed. That is, the first terminal and the second terminal may also obtain user authorization before determining that the fourth terminal is used as the resource pool of the first terminal, so as to ensure the security of subsequent data transmission.

When receiving the terminal information of the fourth terminal sent by the first terminal, the second terminal may store the terminal information of the fourth terminal in correspondence with the terminal information of the first terminal. Similarly, the first terminal may store the terminal information of the fourth terminal when acquiring the terminal information of the fourth terminal, and the fourth terminal may store the terminal information of the second terminal when acquiring the terminal information of the second terminal. In some embodiments, the first terminal or the second terminal may not store the terminal information of the fourth terminal. In other embodiments, the first terminal or the second terminal may store the terminal information of the fourth terminal and the terminal information of the first terminal in the resource pool association relationship, and the resource pool association relationship may be used to indicate the relationship with any The terminal set associated with the terminal.

It should be noted that when both the fourth terminal and the second terminal store the terminal information of the opposite terminal, the subsequent fourth terminal and the second terminal can automatically establish a communication link without the need for other operations such as authentication, which is not only more efficient. It can also reduce user perception and improve user experience.

In some embodiments, since the fourth terminal or the second terminal can establish a communication connection between the fourth terminal and the second terminal as long as one terminal device has the terminal information of the other terminal device, the first terminal may not The terminal information of the second terminal is sent to the fourth terminal, or the first terminal may not send the terminal information of the fourth terminal to the second terminal.

When mobile phone A receives the user's selection operation based on the checkbox on the left side of mobile phone B and receives the user's click operation based on the OK button, it can send an association to mobile phone B through the Wi-Fi communication link with mobile phone B Request to request to use mobile phone B as the resource pool of mobile phone A. In addition, when the mobile phone A receives the user's click operation based on the help button, more explanatory information about the resource pool can be displayed to the user. The mobile phone B receives the association request sent by the mobile phone A and displays the association prompt interface as shown in FIG. 6 . In Figure 6, mobile phone B prompts the user to establish an association with mobile phone A through a pop-up window, whether it is determined to be the resource pool of mobile phone A, and also provides an agree button and a reject button, and what is the resource pool is also displayed at the bottom of the pop-up window. Wait for the help button. When mobile phone B receives the user's click operation based on the agree button, it sends an association response to mobile phone A through the Wi-Fi communication link with mobile phone A; when mobile phone B receives the user's click operation based on the reject button, it can Do not respond to the association request of mobile phone A; when mobile phone B receives the user's click operation based on the help button, it can display more explanatory information about the resource pool to the user. When mobile phone A receives the association response from mobile phone B, it can send the Bluetooth name and password of mobile phone B to the smart watch through the Bluetooth communication link with the smart watch. The Bluetooth name and password of the smart watch are sent to the mobile phone B, so that the mobile phone B and the smart watch can obtain the terminal information of the opposite end respectively.

The first terminal can be associated with M fourth terminals by performing the above S301-S303, where M≧1 and M is a positive integer, so as to obtain a terminal set associated with the first terminal, where the terminal set includes M fourth terminals. The fourth terminal can be used as the resource pool of the first terminal, and then the first terminal can send data to the second terminal through the fourth terminal subsequently. Of course, in some embodiments, the first terminal and the second terminal may delete the terminal information of the fourth terminal, so that the fourth terminal is no longer used as the resource pool of the first terminal. Correspondingly, the fourth terminal may also delete the terminal information of the second terminal so as not to be used as the resource pool of the first terminal.

For example, the smart watch obtains the Bluetooth names of mobile phone B, mobile phone C, mobile phone D, and mobile phone E sent by mobile phone A, respectively, and stores the Bluetooth names of mobile phone B, mobile phone C, mobile phone D, and mobile phone E in the following table 1.

In some embodiments, the first terminal may send first screening information to the second terminal, and the first screening information may be in a manner of instructing the second terminal to acquire the third terminal or indicating restrictions on the third terminal, for example, the first screening The information may include a first number threshold for instructing the second terminal to determine N third terminals in the terminal set associated with the first terminal, where M≧N≧1 and N is a positive integer. Of course, in practical applications, the first screening information may also include more or less information, so as to instruct the second terminal to acquire the third terminal more accurately, thereby improving the subsequent transmission effect of the first data, including better transmission speed , transmission quality or security.

It should be noted that, the first terminal or the second terminal may be a set of terminals associated with the first terminal obtained by the terminal association method shown in FIG. 3, or may be obtained by other methods. The manner of the terminal set associated with the first terminal is not specifically limited.

In some embodiments, the first terminal may send the first selection notification to the second terminal when it is determined that the first terminal, the second terminal, the first link or the first data satisfy a preset transmission condition. The preset transmission condition is used to trigger the first terminal to send at least part of the first data to the second terminal through the resource pool of the first terminal.

It should be noted that the preset transmission conditions can be obtained by setting in advance. In some embodiments, since in short-range communication, the transmission speed is easily affected by the distance between terminal devices, the stability is poor, and the maximum transmission speed supported by some short-range transmission protocols is low, so the first terminal When it is determined that the first link is a communication link based on a preset short-range communication protocol (such as a Bluetooth protocol or a zigbee protocol), a first data selection notification may be sent to the second terminal. In some embodiments, the first terminal may send the first data to the second terminal when it is determined that the size of the first data is greater than the preset data size. In some embodiments, the first terminal may send the first selection notification to the second terminal when it is determined that the terminal identifier of the first terminal or the second terminal is the first preset terminal identifier. Of course, in practical applications, the preset transmission condition may include more or less information, and the specific content of the preset transmission condition is not limited in this embodiment of the present application.

S703, the second terminal acquires terminal information of the third terminal from the terminal set associated with the first terminal.

When receiving the first selection notification sent by the first terminal, the second terminal may determine the third terminal from the M fourth terminals included in the terminal set associated with the first terminal, and then obtain the terminal information of the third terminal . In some embodiments, the second terminal may receive the terminal set associated with the first terminal sent by the first terminal; in other embodiments, the second terminal may obtain the terminal set associated with the first terminal from the local terminal, wherein The set of terminals associated with the first terminal stored by the second terminal may be acquired by the second terminal in advance (for example, from the first terminal).

The second terminal may acquire the transmission speed of the first link, the transmission speed between the eleventh link between the second terminal and the fourth terminal, and the transmission speed of the twelfth link between the first terminal and the fourth terminal If the average transmission speed of the eleventh link and the twelfth link is greater than the transmission speed of the first link, the second terminal may determine the fourth terminal as the third terminal, and accordingly, The second terminal may determine the eleventh link with the fourth terminal as the second link, and the twelfth link between the first terminal and the fourth terminal as the third link. In some embodiments, if there is more than one fourth terminal, and the average transmission speed of the eleventh link and the twelfth link corresponding to the fourth terminal is greater than the transmission speed of the first link, the second terminal may According to the order of the average transmission speed of the eleventh link and the twelfth link from high to low, N fourth terminals are selected from more than one fourth terminal as the third terminals, N≥1.

For example, the first preset communication protocol may include the aforementioned preset short-range communication protocols, such as the Bluetooth protocol or the zigbee protocol, and the second preset communication protocol may include a mobile communication protocol (such as 4G or 5G) or a Wi-Fi protocol. .

It should be noted that the second terminal may retain the eleventh link between the second terminal and the fourth terminal except the third terminal, so as to save the time spent in disconnecting the eleventh link and further improve the efficiency . Of course, the second terminal may also cut off the eleventh link between the second terminal and other fourth terminals except the third terminal. Similarly, the first terminal or other fourth terminals except the third terminal may also reserve the twelfth link between the first middle terminal and the other fourth terminals except the third terminal, so as to save the disconnection of the first terminal. Time spent on twelve links. Of course, the twelfth link between the first terminal and other fourth terminals except the third terminal may also be reserved between the first terminal and other fourth terminals except the third terminal.

In some embodiments, the second terminal may cut off the eleventh link with the other fourth terminal when determining the third terminal, and the second terminal may also instruct the other fourth terminal or the first terminal to cut off the The twelfth link between the other fourth terminal and the first terminal.

In some embodiments, if the second terminal ignores the transmission speed of the twelfth link between the first terminal and each fourth terminal when determining the third terminal, the second terminal can When the transmission speed of the eleventh link between the terminals is increased, the eleventh link with the fourth terminal is cut off. The second terminal may also instruct the fourth terminal or the first terminal to cut off the link with the fourth terminal. Twelfth link between terminals.

For example, referring to FIG. 9 , when the smart watch (220 in FIG. 9 ) receives the first selection notification sent by mobile phone A (210 in FIG. 9 ), it determines that the terminal set associated with mobile phone A includes mobile phone B ( FIG. 9 ). 271 in Figure 9), mobile phone C (272 in Figure 9), and mobile phone D (273 in Figure 9). The smart watch detects that the transmission speed of the Bluetooth communication link between the smart watch and mobile phone A is 60k/s (kilobytes per second), and the transmission speed of the Bluetooth communication link between the smart watch and mobile phone B is 40k/s s, the transmission speed of the Bluetooth communication link between the smart watch and the mobile phone C is 120k/s, and the transmission speed of the Bluetooth communication link between the smart watch and the mobile phone D is 80k/s. Since the transmission speed of the Bluetooth communication link between the smart watch and mobile phone C is the highest, the smart watch determines mobile phone C as the third terminal and cuts off the Bluetooth communication link between the smart watch and mobile phone A, mobile phone B and mobile phone D respectively. .

In some embodiments, if the second terminal ignores the transmission speed of the twelfth link between the first terminal and each fourth terminal when determining the third terminal, the second terminal may obtain the second terminal and one When the transmission speed of the eleventh link between the fourth terminals is greater than the transmission speed of the eleventh link between the second terminal and another fourth terminal, the second terminal cuts off the eleventh link with a lower transmission speed link, the second terminal may further instruct the first terminal or the fourth terminal corresponding to the eleventh link with a lower transmission speed to cut off the eleventh link with a lower transmission speed.

In some embodiments, since the transmission speed is limited by the hardware conditions of the terminal device, and the hardware update cycle of the terminal device is relatively low, even some terminal devices will not update the hardware in the entire life cycle, that is, for different terminal devices In terms of equipment, the terminal identification (such as terminal name and terminal model, etc.) of the terminal equipment is related to the transmission speed supported by the terminal equipment. Therefore, in order to improve the efficiency of determining the third terminal, when the second terminal determines the third terminal from the terminal set associated with the first terminal, it may not be necessary to acquire the transmission of the eleventh link between the fourth terminal and the second terminal It is not necessary to obtain the transmission speed of the twelfth link between the fourth terminal and the first terminal, but to obtain the terminal information of each fourth terminal included in the terminal set associated with the first terminal, where the terminal information includes the terminal identifier, and the fourth terminal corresponding to the second preset terminal identifier is determined as the third terminal.

For example, the smart watch determines that the terminal set associated with mobile phone A includes mobile phone B, mobile phone C, mobile phone D, and mobile phone E, wherein the model of mobile phone B is mt30, the model of mobile phone C is no1, the model of mobile phone D is mt20, and the model of mobile phone E is mt20. The model of B is ooace, and the smart watch determines that the second preset terminal identifier is mt30, then the smart watch can determine the mobile phone B as the third terminal. It should be noted that the above mt30, no1, mt20 and ooace are only fictitious terminal models for describing the embodiments of the present application, and the above mt30, no1, mt20 and ooace do not constitute any limitations on the terminals in the embodiments of the present application.

In addition, in some embodiments, steps similar to the foregoing S703 may be performed by the first terminal to obtain terminal information of the third terminal from the terminal set associated with the first terminal, and accordingly, the following S704 may be omitted.

S704, the second terminal sends the terminal information of the third terminal to the first terminal.

The second terminal may send the terminal information of the third terminal to the first terminal, then when the first terminal receives the terminal information of the third terminal, it may determine each third terminal that subsequently transmits data to the second terminal.

In some embodiments, after the second terminal sends the terminal information of the third terminal to the first terminal, or when the first terminal receives the terminal information of the third terminal, the communication between the first terminal and the second terminal may be cut off. first link.

For example, referring to FIG. 10 , the twelfth communication link between mobile phone A (210 in FIG. 10 ) and mobile phone B (230 in FIG. 10 ) is a 4G/5G/Wi-Fi communication link, and mobile phone A and The first link between the smart watches (220 in FIG. 10 ) and the eleventh link between the mobile phone B and the smart watch are Bluetooth communication links. Since the Bluetooth protocol is a low-power communication protocol, the time spent on the twelfth link is negligible compared to the time spent on the first link or on the eleventh link, as long as the data is transmitted on the twelfth link. The transmission speed of the eleventh link is higher than that of the first link, so the efficiency of mobile phone A sending data to the smart watch through the twelfth link and the eleventh link will be higher than that of mobile phone A sending data to the smart watch through the first link. The efficiency with which the watch sends this data. Therefore, when the smartwatch detects that the transmission speed of the first link is 30k/s and the transmission speed of the eleventh link is 80k/s, since 80k/s>30k/s, the smartwatch sends the mobile phone to mobile phone A. terminal information of B, and then cut off the first link with the mobile phone A, so that the subsequent mobile phone A transmits data to the smart watch through the twelfth link and the eleventh link.

In some embodiments, the second terminal may send the transmission speed of the first link, the transmission speed of the second link and the transmission speed of the third link to the first terminal, so that the first terminal based on the transmission speed of the first link The transmission speed, the transmission speed of the second link, and the transmission speed of the third link more precisely control the transmission process of the first data.

S705, the first terminal outputs transmission prompt information.

By transmitting the prompt information, the user is reminded that at least part of the first data is about to be sent through the resource pool, and the specific path of data transmission can be truly shown to the user, so as to ensure the security of the data. Data transmission operations are controlled or other operations, such as suspending transmission or debugging according to the subsequent transmission process, etc.

Referring to FIG. 11 , mobile phone A receives the terminal information of mobile phone B sent by the smart watch, so it can display the transmission prompt message to the user: "I will send data to my watch through mobile phone B". In addition, the mobile phone A can also display three buttons "OK", "Reject" and "Cancel". If the mobile phone A receives the user's click operation based on the "OK" button, it can continue to perform the subsequent steps. If the mobile phone A receives the user's click operation based on the "reject" button, the first data may be sent to the second terminal through the first connection, that is, at least part of the first data will no longer be sent through the resource pool. If the mobile phone A receives the user's click operation based on the "Cancel" button, the sending of the first data can be canceled.

In some embodiments, before S702, the mobile phone A may display transmission prompt information in a manner similar to or the same as that of S705, to prompt the user that at least part of the first data is about to be sent through the resource pool.

In addition, in some embodiments, S705 can also be omitted. On the one hand, the interaction with the user is reduced, so that the transmission process is more concise and efficient; Sending the first data to the second terminal by the first terminal has the same user experience, that is, optimizing the user experience.

S706, the first terminal transmits at least part of the first data to the second terminal via the third link and the second link.

It can be seen from the foregoing that the speed at which the first terminal transmits data to the second terminal through the second link and the third link is greater than the speed at which the first terminal transmits data to the second terminal through the first link. Therefore, when the first terminal transmits data to the second terminal through the first link When the first data needs to be transmitted to the second terminal, at least part of the first data can be transmitted to the second terminal through the second link and the third link, thereby improving the efficiency of transmitting the first data to the second terminal.

In some embodiments, the first terminal may transmit the first data to the second terminal through the second link and the third link, so as to maximize the efficiency of transmitting the first data. In other embodiments, the first data includes Q different first parts and P second parts, where 1≤Q=N, P is 1 or 0, and N is the number of third terminals. The first terminal transmits Q different first parts of the first data to the second terminal through the N second links and N third links respectively, and transmits the second part of the first data through the first link, Correspondingly, when receiving the Q different first parts and the P second parts, the second terminal may combine the Q different first parts and the P second parts into the first data.

If the number of third terminals N>1, and the first terminal sends the first data to the first terminal through the third terminal, the first terminal can use the third link with each third terminal and the third terminal The second link between the second terminal and the second terminal sends the first data to the second terminal, that is, the first terminal can transmit the first data to the second terminal through N third terminals respectively, and the second terminal can receive the first data at the first When the first data sent by a certain third terminal is reached, stop receiving the first data sent by other third terminals.

If the number of third terminals N>1, the first terminal sends Q different first parts of the first data to the first terminal through the third terminal, Q=N, P=0, then the first terminal can communicate with each The third link between the third terminals and the second link between each third terminal and the second terminal send Q different first parts to the second terminal, and the second terminal receives Q pieces from the N terminals different first parts, and synthesizing Q different first parts into first data. Of course, if P=1, the first terminal can also send the second part to the second terminal through the first link. Correspondingly, the second terminal can combine Q different first parts and one second part into the first part data.

It should be noted that, in practical applications, N may be greater than Q. In this case, at least two first parts of the first data sent by the first terminal to the first terminal through at least two third terminals may be the same, and the second The terminal may, after first receiving the first part from one of the third terminals, no longer receive the same first part sent from the other third terminals among the at least two third terminals.

It should also be noted that the first part and the second part may carry data synthesis information, where the data synthesis information is used to indicate that Q different first parts and P second parts are synthesized into first data. The data synthesis information may include a data identifier of the first data, and a position of the first part or the second part in the first data.

It should also be noted that the first data party may include multiple data packets, and correspondingly, the first part or the second part may include at least one data packet.

For example, referring to Fig. 12, mobile phone A (210 in Fig. 12) obtains the terminal information of mobile phone B (231 in Fig. 12) and mobile phone C (232 in Fig. 12) from the smart watch (220 in Fig. 12) , that is, it is determined that the third terminal includes mobile phone B and mobile phone C. The first data includes 10 data packets such as 0-9. Therefore, mobile phone A sends data packet 2, data packet 5, data packet 6 and data packet 7 of the first data packet to mobile phone B through the Wi-Fi communication link with mobile phone B. The Bluetooth communication link between the two devices sends data packet 2, data packet 5, data packet 6 and data packet 7 to the smart watch. Similarly, mobile phone A sends mobile phone C to mobile phone C through the Wi-Fi communication link with mobile phone C The data packet 0, the data packet 1, the data packet 3, the data packet 4, the data packet 8 and the data packet 9 included in the first data are sent, and the mobile phone C sends the data packet 0, data packet Packet 1, Packet 3, Packet 4, Packet 8 and Packet 9 are sent to the smart watch. The smart watch receives data packet 2, data packet 5, data packet 6 and data packet 7 from mobile phone B, and data packet 0, data packet 1, data packet 3, data packet 4, data packet 8, data packet from mobile phone C 9, and combine data packet 2, data packet 5, data packet 6, data packet 7, data packet 0, data packet 1, data packet 3, data packet 4, data packet 8 and data packet 9 into the first data. Alternatively, the first data further includes data packet 10, data packet 11 and data packet 12, and mobile phone A can send data packet 10, data packet 11 and data packet 12 to the smart watch through the Bluetooth communication link with the smart watch watch, then the smart watch can receive

data packets

10, 11 and 12 from mobile phone A, and include data packets 2, 5, and 6 data packets 7, data packets 0, data packets 1, and data packets 3 , packet 4, packet 8, packet 9, packet 10, packet 11, and packet 12 are combined into first data. In some embodiments, the smart watch can receive data from different terminal devices through different Bluetooth modules, so as to further improve the efficiency of receiving data.

In some embodiments, the first terminal may determine the first portion transmitted via the second link and the third link based on at least one of the transmission speed of the second link and the transmission speed of the third link. Wherein, if the first terminal determines the first part based on the transmission speed of the second link, the data volume of the first part is positively correlated with the transmission speed of the second link; if the first terminal is based on the transmission speed of the third link speed, determine the first part, then the data size of the first part is positively related to the transmission speed of the third link; if the first terminal determines the first part based on the transmission speed of the second link and the transmission speed of the third link, then The data size of the first part is positively related to the transmission speed of the second link and the transmission speed of the third link. That is, by rationally distributing the amount of data transmitted through the link according to the transmission speed of each link, the transmission efficiency is further improved.

If the time spent for data transmission on the third link is negligible relative to the time spent for data transmission on the second link, the first terminal may determine, based on the transmission speeds of the M second links, The size of the data amount of the first part transmitted through each second link, or the first terminal may transmit the first part through each second link based on the transmission speed of the M second links and the transmission speed of the first link The size of the data size and the size of the data size of the second part.

For example, please continue to refer to FIG. 12 , the third link between mobile phone A, mobile phone B and mobile phone C is Wi-Fi communication link, and the second link between mobile phone B and mobile phone C and smart watch is Bluetooth communication Therefore, compared to the time it takes for mobile phone B or mobile phone C to transmit data to the smartwatch through the Bluetooth communication link, the time it takes for mobile phone A to transmit data to mobile phone B or mobile phone C is negligible. Therefore, based on the Bluetooth communication links between the mobile phone B and the mobile phone C and the smart watch, the mobile phone A can determine the size of the first part of the data transmitted through the mobile phone B and the mobile phone C, respectively. The mobile phone A determines that the transmission speed of the Bluetooth communication link between the mobile phone B and the smart watch is 40k/s, and the transmission speed of the Bluetooth communication link between the mobile phone C and the smart watch is 60k/s. Therefore, the first data includes The 10 data packets are divided into two first parts, wherein the first part corresponding to the mobile phone B includes four data packets including data packet 2, data packet 5, data packet 6 and data packet 7, and the first part corresponding to the mobile phone C There are 10 data packets including data packet 0, data packet 1, data packet 3, data packet 4, data packet 8 and data packet 9.

Similarly, if the time spent in data transmission on the second link is negligible compared to the time spent in data transmission on the third link, then the first terminal can transmit data based on M third links. speed, to determine the amount of data of the first part transmitted through each third link, or, the first terminal may transmit through each third link based on the transmission speed of the M third links and the transmission speed of the first link The data size of the first part and the data size of the second part.

Of course, no matter what the difference is between the duration of data transmission on the second link and the duration of data transmission on the third link, the first terminal can obtain the data between each third terminal and the second terminal. The transmission speed of the second link and the transmission speed of the third link between each third terminal and the first terminal, so as to determine the average transmission of the second link and the third link corresponding to each third terminal The data volume of the first part transmitted by each third terminal and the data volume of the first data transmitted by each third terminal are determined according to the average transmission speed corresponding to each third terminal.

For example, the data size of the first data is 10MB (megabytes), please refer to FIG. 9 again. The transmission speed of the Bluetooth communication link between the mobile phone A and the smart watch is 60k/s, and the transmission speed of the Bluetooth communication link between the mobile phone C and the smart watch is 120 k/s. If the mobile phone A directly transmits the first data through the Bluetooth communication link between the mobile phone A and the smart watch, it takes 10*1024/60=170s. If the mobile phone C directly transmits the first data through the Bluetooth communication link between the mobile phone C and the smart watch, it takes 10*1024/120=85s. Among them, the mobile phone A can send the first data to the mobile phone C through the Wi-Fi communication link, which takes far less than 85s, so it can be ignored. In addition, the smart watch establishes a Bluetooth communication link with mobile phone A, mobile phone B, mobile phone C and mobile phone D respectively, which takes 2s*4=8s; The transmission speed of the Bluetooth communication connection between the two takes 2s*4=8s; the smart watch disconnects the Bluetooth communication link with mobile phone A, mobile phone B and mobile phone D, which takes 2s*3=6s; mobile phone A It takes 2s to establish a Wi-Fi communication link with mobile phone C; mobile phone A establishes associations with mobile phone B, mobile phone C, and mobile phone D in advance, that is, mobile phone B, mobile phone C, and mobile phone D are used as mobile phone A resources pool, which takes 10*3=30s. And because mobile phone A only needs to establish an association relationship with mobile phone B, mobile phone C, and mobile phone D at a certain time, it can permanently use mobile phone B, mobile phone C, and mobile phone D as the resource pool of mobile phone A, so this part of the time consumption can be If ignored, in the embodiment of the present application, the total time required for the mobile phone A to send the first data to the smart watch through the mobile phone C may be 85s+8s+8s+6s+2s=109s. A. For the Bluetooth communication link between the mobile phone B and the mobile phone D, the total time-consuming can be saved by another 6s, that is, the time-consuming can be shortened to 103s. It can be seen that the transmission time of the first data is reduced from 170s to 109s or 103s, which significantly improves the transmission efficiency.

In some embodiments, when the second terminal receives the first data, it may cut off (or instruct the third terminal to cut off) the second link, and instruct the first terminal or the third terminal to cut off the third link. And if the current first link has been disconnected, the second terminal may establish the first link again. That is, when the first data transmission is completed, the second terminal can restore the connection relationship between the first terminal, the second terminal and the third terminal to the state before the transmission of the first data, which is convenient for subsequent first data transmission. The terminal and the second terminal perform other possible interactive operations to improve the interaction efficiency. On the other hand, it can further reduce user perception and improve user experience.

In some embodiments, if the first terminal has not received the terminal information of the third terminal sent by the second terminal, it may be that the second terminal has not acquired the third terminal, that is, the transmission speed of the first link is greater than or equal to It is equal to the average transmission speed of the second link and the third link, therefore, the first terminal can transmit the first data to the second terminal based on the first link.

It should be noted that the above-mentioned first terminal, second terminal or third terminal can be interchanged. For example, the first terminal can perform the operations performed by the above-mentioned second terminal to receive data from other terminal devices; the first terminal can Perform the operations performed by the third terminal to forward data to other terminal devices.

In some embodiments, the first terminal may receive a second selection notification from the fifth terminal, and the first terminal determines the first selection from the K seventh terminals included in the terminal set associated with the fifth terminal according to the second selection notification. Six terminals, K≥1 and K is a positive integer, the first terminal sends the terminal information of the sixth terminal to the fifth terminal, wherein the terminal information of the sixth terminal is used for the fifth terminal, via the sixth link and the fifth link route, sending at least part of the second data to the first terminal, the fifth link is the communication link between the first terminal and the sixth terminal, and the sixth link is the communication link between the fifth terminal and the sixth terminal The link, the transmission speed of the fourth link between the terminal and the fifth terminal, is smaller than the average transmission speed of the fifth link and the sixth link.

The first terminal may receive in advance the terminal information of the K seventh terminals sent by the fifth terminal.

In some embodiments, the first terminal may obtain the transmission speed of the seventh link of the K seventh terminals in the terminal set associated with the first terminal and the fifth terminal, and the transmission speed of the first link, the first terminal The seventh terminals corresponding to the L seventh links are determined as the sixth terminal, wherein the transmission speed of the L seventh terminals is greater than the transmission speed of the first link, K≥L≥1 and L is a positive integer, wherein, The eighth link between the first terminal and any seventh terminal is a communication link based on the first preset communication protocol, and the seventh link between any seventh terminal and the fifth terminal is based on the second preset communication protocol. Assuming the communication link of the communication protocol, the difference between the maximum transmission speed indicated by the second preset communication protocol and the maximum transmission speed indicated by the first preset communication protocol is greater than the first speed threshold. Of course, if the eighth link between the first terminal and any seventh terminal is a communication link based on the second preset communication protocol, the seventh link between any seventh terminal and the fifth terminal is a communication link based on the second preset communication protocol. The communication link of the first preset communication protocol, the first terminal may also determine the seventh terminal corresponding to the L eighth links as the sixth terminal, wherein the transmission speed of the L eighth links is greater than that of the first link the transmission speed of the road.

In some embodiments, the first terminal may, in order of transmission speed from high to low, determine the L seven terminals corresponding to the seventh link whose transmission speed is greater than that of the first link, and use the acquired L The seventh terminal is determined to be the sixth terminal.
