Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

Fig. 1 is a schematic diagram of a system architecture of an exemplary application environment to which a data transmission method and apparatus of an embodiment of the present disclosure may be applied.

As shown in fig. 1, the system architecture 100 may include at least terminal devices 101, 102 and a network 103. The network 103 serves as a medium providing at least a communication link between the terminal devices 101, 102. Network 103 may include wired, one or more wireless communication links, and the like. The terminal devices 101, 102 may be a variety of electronic devices having data transfer capabilities including, but not limited to, smart phones, smart watches, desktop computers, portable computers, tablet computers, and the like. It should be understood that the number of terminal devices, networks in fig. 1 is merely illustrative. Any number of terminal devices, networks, may also be added as desired for implementation. The data transmission method provided by the embodiments of the present disclosure is generally performed in the terminal devices 101, 102, and accordingly, the data transmission apparatus is generally provided in the terminal devices 101, 102. For example, after the wired data transmission link and the wireless data transmission link between the terminal devices 101 and 102 are established, the data transmission method provided in the embodiments of the present disclosure may be executed by the terminal device 101, the data to be transmitted in the terminal device 101 is sent to the terminal device 102 through the wired data transmission link and the wireless data transmission link, and received by the terminal device 102, and correspondingly, the data transmission method provided in the embodiments of the present disclosure may also be executed by the terminal device 102, and the data to be transmitted in the terminal device 102 is sent to the terminal device 101 through the wired data transmission link and the wireless data transmission link, and received by the terminal device 101.

In the related art, the terminal device supports data transmission through a cellular network module, and can also realize data transmission through a local area network communication module, such as a Wi-Fi module, a Bluetooth module, and the like, however, in a manner of performing data transmission through such wireless connection, the data transmission rate is easily affected by the physical environment of the current transmission to cause unstable transmission rate, for example, when a large number of wireless networks exist in the current use environment, the data transmission rate between the terminal devices is greatly reduced, the data transmission rate may even be reduced to 1/10 of the normal transmission rate, and the data transmission rate is limited by the wireless throughput rate of the terminal device. The terminal devices are connected by a universal serial bus USB, but the data transmission rate is limited by the USB transmission rate, for example, the USB 2.0 transmission rate is 20M/s, the USB 3.0 transmission rate is 40M/s, and the terminal devices can only transmit data in a serial manner by the wired connection mode, so that the terminal devices consume a lot of time to continuously open the data to be transmitted, read the content to be transmitted, and consume more time if smaller data to be transmitted is sent by the wired data transmission connection, thereby reducing the utilization rate of the wired data transmission link and limiting the data transmission rate.

In view of one or more of the problems described above, example embodiments of the present disclosure provide a data transmission method. The data transmission method may be applied to one or more of the above-described terminal apparatuses 101, 102, which is not particularly limited in the present exemplary embodiment. Referring to fig. 2, the data transmission method may include the following steps S210 to S230:

In step S210, a wired data transmission link with the second terminal device is established, and a wireless data transmission link with the second terminal device is established.

In embodiments of the present disclosure, a wireless data transmission link may include one or more transmission channels, which may be used for data transmission in parallel when the wireless data transmission link is a plurality of transmission channels. For convenience of distinction, the data transmitting device is denoted as a first terminal device, the data receiving device is denoted as a second terminal device, i.e. the first terminal device may first establish a wired data transmission link with the second terminal device and a wireless data transmission link with the second terminal device, wherein the wired data transmission link and the wireless data transmission link are independent from each other. For example, a wired data transmission link is established between the device a and the device B, and a wireless data transmission link is established, when the device a is to send data to be transmitted to the device B, the device a is used as a first terminal device, and the device B is used as a second terminal device; accordingly, when the device B sends data to be transmitted to the device a, the device B serves as a first terminal device, and the device a serves as a second terminal device, that is, in the embodiment of the present disclosure, the first terminal device and the second terminal device are relative concepts, not absolute concepts.

In addition to the first terminal device and the second terminal device establishing the wired data transmission link and the wireless data transmission link, only the wired data transmission link between the first terminal device and the second terminal device, or only the wireless data transmission link between the first terminal device and the second terminal device may be established according to the actual data transmission scenario. That is, in the embodiment of the present disclosure, the data transmitting apparatus and the data receiving apparatus may switch between the double link data transmission and the single link data transmission.

In some possible embodiments, the first terminal device may first establish a wired data transmission link with the second terminal device, and during data transmission through the wired data transmission link, establish a wireless data transmission link between the first terminal device and the second terminal device, and thereafter switch the single-link data transmission (wired data transmission) to dual-link data transmission. Correspondingly, the first terminal device may first establish a wireless data transmission link with the second terminal device, and establish a wired data transmission link between the first terminal device and the second terminal device in the process of performing data transmission through the wireless data transmission link, and thereafter, switch the single-link data transmission (wireless data transmission) to the dual-link data transmission.

In some possible embodiments, the wired data transmission link or the wireless data transmission link may be disconnected when the first terminal device and the second terminal device perform dual-link data transmission through the wired and wireless data transmission links, and thereafter, the dual-link data transmission is switched to the single-link data transmission (wireless data transmission or wired data transmission).

It is noted that, when transmitting data through the dual link, the number of transmission channels included in the wireless data transmission link may be switched to one or more according to the actual transmission scenario. For example, when the number of transmission channels of the wired data transmission link is one, in order to increase the utilization rate of the wired data transmission link, the number of transmission channels included in the wireless data transmission link may be plural in order to transmit data having a smaller data amount in parallel through the plural transmission channels, and when data is transmitted through only one wireless data transmission channel, the number of transmission channels of the wireless data transmission link may be one, which is not particularly limited in the embodiment of the present disclosure.

When the dual-link data transmission is adopted between the terminal devices, the sequence of establishing the wired data transmission link and the wireless data transmission link is not particularly limited, the wired data transmission link can be established first, the wireless data transmission link can be established again, the wireless data transmission link can be established first, the wired data transmission link can be established again, and the wired/wireless data transmission link can be established simultaneously.

By the embodiment of the disclosure, a wired data transmission link and a wireless data transmission link comprising one or more transmission channels are established between the first terminal equipment and the second terminal equipment, so that the subsequent data transmission can be conveniently performed through the wired data transmission link and the wireless data transmission link, and the terminal equipment can be switched between single/double-link data transmission to meet different data transmission requirements.

In step S220, in response to the data transmission instruction, first transmission data and second transmission data in the data to be transmitted are acquired, wherein the data amount of the first transmission data is larger than the data amount of the second transmission data.

In embodiments of the present disclosure, the data transmission instruction may be an instruction triggered by a user using the first terminal device, e.g. by clicking, sliding a virtual object of the terminal device interface, panning, rotating or shaking the terminal device, etc. Although there is no dependency between the wired data transmission link and the wireless data transmission link, the data transmission processes between the wired data transmission link and the wireless data transmission link do not interfere with each other, in the embodiment of the disclosure, the wired data transmission link and the wireless data transmission link share data to be transmitted, and according to a preset data transmission policy, corresponding first transmission data/second transmission data are respectively obtained from the shared data to be transmitted, so that the first transmission data are sent to the second terminal device through the wired data transmission link, and the second transmission data are sent through the wireless data transmission link. The data to be transmitted is obtained through the cooperative coordination of the wired data transmission link and the wireless data transmission link so as to meet different data transmission requirements and improve the data transmission rate.

In an exemplary embodiment of the present disclosure, the number of transmission channels of the wireless data transmission link is greater than the number of transmission channels of the wired data transmission link, and the second transmission data having a smaller data amount is transmitted through the wireless data transmission link having a larger transmission channel, and the first transmission data having a larger data amount is transmitted through the wired data transmission link having a smaller transmission channel. The data transmission process at least comprises the steps of opening the data to be transmitted and reading the content of the data to be transmitted, and then sending the data to be transmitted, if the data with smaller data quantity is transmitted through the wired data transmission link, the data transmission process is required to be frequently executed, so that the channel utilization rate of the wired data transmission link is low, and the data transmission process is executed in parallel through more transmission channels of the wireless data transmission link, so that the time consumed by opening the data to be transmitted and reading the content to be transmitted in the data transmission process of the wired data transmission link is balanced, and the channel utilization rate of the wired and wireless data transmission links is improved.

Since the wireless data transmission link may include a plurality of transmission channels, in response to the data transmission instruction, in step S220, the second transmission data among the data to be transmitted may be acquired in parallel so as to be transmitted to the second terminal device in parallel through the plurality of transmission channels in the wireless data transmission link. As shown in fig. 3, in an exemplary embodiment of the present disclosure, second transmission data corresponding to a wireless data transmission channel is obtained in parallel, in a data transmission process, in a wired data transmission link portion, first transmission data is obtained from data to be transmitted through a wired data transmission link a, in a wireless data transmission link portion, second transmission data (1, 2,3 … … n) is obtained from data to be transmitted in parallel through a plurality of transmission channels (b 1, b2, b3 … … bn), and in combination with the wired/wireless data transmission link, the data transmission amount per unit time is increased.

Because the wired data transmission link is serial transmission, the process of sending the data to be transmitted by the first terminal device includes opening the data to be transmitted, reading the content of the data to be transmitted and sending the data to be transmitted, if the data with smaller data quantity is transmitted through the wired data transmission link, the first terminal device will consume more time in continuously opening and reading the data, and the channel utilization rate of the wired data transmission link is lower. Correspondingly, based on the wireless data transmission link, a plurality of data to be transmitted can be sent to the second terminal device in parallel through a plurality of transmission channels, namely, the opening and reading operations of the plurality of data to be transmitted can be simultaneously carried out through a transmission mode of the plurality of transmission channels, so that the data with smaller data quantity is preferentially processed through the wireless data transmission link, the data with larger data quantity is preferentially processed through the wired data transmission connection, and the channel utilization rate and the data transmission rate of the wired data transmission link can be improved. Therefore, in the embodiment of the disclosure, data with larger data volume is obtained as the first transmission data to be transmitted through the wired data transmission link, the second transmission data with smaller data volume is preferentially transmitted through the plurality of transmission channels of the wireless data transmission link, the transmission link is prevented from presenting an idle state, the wired data transmission link and the wireless data transmission link are fully utilized to carry out full-load transmission, and the data transmission rate is improved.

It should be noted that, in order to distinguish the data to be transmitted with different data sizes, the data with larger data size is recorded as the first transmission data, the data with smaller data size is recorded as the second transmission data, that is, the data size of the first transmission data is larger than the data size of the second transmission data, and the types, formats and the like of the first transmission data and the second transmission data may be different or the same, that is, the "first" and the "second" are only identifiers for distinguishing, and are not limited to the specific number, the specific type and the like of the data to be transmitted.

In step S230, the first transmission data is transmitted to the second terminal device via the wired data transmission link, and the second transmission data is transmitted to the second terminal device via the wireless data transmission link.

In an embodiment of the present disclosure, the first transmission data is sent to the second terminal device through a wired data transmission link, and the second transmission data is sent to the second terminal device through a wireless data transmission link.

Wherein the first transmission data and the second transmission data may be transmitted in parallel to the second terminal device through the wired data transmission link and the wireless data transmission link, where "in parallel" is used to indicate that transmission operations for different data among the data to be transmitted are simultaneously performed through the wired data transmission link and the wireless data transmission link, there may be a case where the amount of the data to be transmitted finally transmitted through the wired data transmission link and the wireless data transmission link is different, that is, the first amount of the first transmission data transmitted through the wired data transmission link is different from the second amount of the second transmission data transmitted through the wireless data transmission link, since at least one of the types, the data amount sizes, the transmission rates of the wired data transmission link, and the transmission rates of the wireless data transmission link may be different. For example, the data to be transmitted includes 128 files (including but not limited to audio, video, pictures, files and application data), and after the double link data transmission through the wired and wireless data transmission links, 50 files are transmitted to the second terminal device through the wired data transmission link, and 78 files are transmitted to the second terminal device through the wireless data transmission link. Of course, in some possible embodiments, if the wired data transmission link is abnormal or the transmission rate is lower than the preset rate threshold, the method may switch to single link transmission through the wireless data transmission link, and conversely, if the wireless data transmission link is abnormal or the transmission rate is lower than the preset rate threshold, the method may switch to single link transmission through the wired data transmission link, where the embodiments of the present disclosure may schedule the wired data transmission link and the wireless data transmission link to transmit data according to an actual data transmission scenario.

According to the data transmission method provided by the embodiment of the disclosure, the wire data transmission link and the wireless data transmission link which are independent of each other are established between the first terminal equipment and the second terminal equipment, and the wire data transmission link and the wireless data transmission link jointly process data to be processed, so that the data transmission rate is improved, even if the transmission is interrupted due to the abnormality of one transmission link in the wire data transmission link or the wireless data transmission link in the data transmission process, the other transmission link can still normally perform data transmission, and the robustness and the stability of the data transmission are ensured. Meanwhile, the data is transmitted in a wired data transmission link mode, the problems that the wireless data transmission link is easily influenced by physical environment and the transmission rate is unstable are solved, the data is transmitted in a wireless data transmission link mode, the problems that the wired data transmission link is easily limited by the transmission rate of a universal serial bus, the data transmission rate is influenced by low utilization rate of a data transmission channel and the like are solved, the data transmission efficiency between terminal devices is improved, and the user experience is good.

In an exemplary embodiment of the present disclosure, an implementation of a data transmission policy for data to be transmitted is also provided. In response to the data transmission instruction, acquiring the first transmission data and the second transmission data of the data to be transmitted may include the following steps S410 to S430:

In step S410, the data to be transmitted is allocated to the data queues corresponding to different data size classes according to the data size of the data to be transmitted.

In an exemplary embodiment of the present disclosure, the data size level is obtained by dividing according to a data size threshold, where the height of the data size level indicates the data size of the data to be transmitted in the corresponding data queue, the data size of the data to be transmitted in the data queue of the high data size level is greater than the data size of the data to be transmitted in the data queue of the low data size level, that is, the data size level is higher, the data size of the data to be transmitted in the corresponding data queue is indicated to be greater, and conversely, the data size level is lower, the data size of the data to be transmitted in the corresponding data queue is indicated to be smaller.

For example, as shown in fig. 5, a schematic diagram of dividing a data queue according to an exemplary embodiment of the present disclosure is shown, as shown in fig. 5, the data amount of the data to be transmitted is compared with a data amount threshold 100M, if the data amount of the data to be transmitted is greater than or equal to the data amount threshold 100M, the data to be transmitted is divided into a data queue a, if the data amount of the data to be transmitted is less than the data amount threshold 100M, the data to be transmitted is divided into a data queue B, and so on, all the data to be transmitted are distributed into the corresponding data queues according to the comparison result with the data amount threshold. Wherein the data volume level of the data queue a is higher than the data volume level of the data queue B. With continued reference to fig. 6, if the preset data amount threshold includes 100M and 500M, the data to be transmitted is divided into a data queue a (the data amount of the data to be transmitted is greater than 500M), a data queue B (the data amount of the data to be transmitted is greater than or equal to 100M and less than or equal to 500M), and a data queue C (the data amount of the data to be transmitted is less than 100M) according to the data amount threshold. The data volume levels of the data queues a to C are sequentially reduced.

It should be noted that the data volume thresholds and the divided data queues in fig. 5 and 6 are merely illustrative, and the embodiments of the present disclosure may select different data volume thresholds to divide the data to be transmitted into a plurality of data queues according to actual data transmission scenarios.

In step S420, a first target data queue is determined from the plurality of data queues in order of the data volume level from high to low to obtain first transmission data from the first target data queue.

In the exemplary embodiment of the present disclosure, since data having a larger data amount is first acquired as the first transmission data, the first transmission data may be acquired from the data queue in order of the data amount level from high to low. In the process of acquiring the first transmission data, after all the data to be transmitted in the data queue of the previous data volume level is transmitted, acquiring the data to be transmitted from the data queue of the next data volume level adjacent to the data queue of the previous data volume level as the first transmission data.

With continued reference to fig. 6, the data queue a is first determined to be a first target data queue and first transmission data is acquired from the data queue a, the data queue B is determined to be a first target data queue and first transmission data is acquired from the data queue B after all the data to be transmitted in the data queue a are transmitted, and the data queue C is determined to be a first target data queue and first transmission data is acquired from the data queue C after all the data to be transmitted in the data queue B are transmitted.

According to the data transmission method and device, the data to be transmitted is divided into the plurality of data queues with different data volume levels, first transmission data can be acquired from the data queues with high data volume levels and distributed to the wired data transmission link, the data with larger data volume can be preferentially transmitted through the wired data transmission link, the data transmission link is based on serial transmission, the time consumption in data opening and data reading is avoided, the utilization rate of a data transmission channel is guaranteed, the wired data transmission link is not easy to be influenced by physical environment, the data with larger data volume is transmitted through the wired data transmission link, transmission interruption caused by physical environment is avoided, data transmission stability is higher, in addition, the first transmission data/second transmission data can be acquired from different data queues through the wired/wireless data transmission link, the data volume of the first transmission data is ensured to be larger than that of the second transmission data, and the time consumed for ordering the data to be transmitted is avoided.

In step S430, a second target data queue is determined from the data queues in order of the data volume level from low to high to obtain second transmission data from the second target data queue.

In the exemplary embodiment of the present disclosure, since data of smaller data amount is first acquired as the second transmission data, the second transmission data can be acquired from the data queues corresponding to different data amount levels in order of the data amount levels from low to high. And in the process of acquiring the second transmission data, acquiring the data to be transmitted from the data queue of the next data volume level adjacent to the data queue of the previous data volume level as the second transmission data after all the data to be transmitted in the data queue of the previous data volume level are transmitted.

Continuing to refer to the example of fig. 6, in the order of the data queue C, the data queue B and the data queue a, the data queue C is first determined to be a second target data queue, the second transmission data is acquired from the data queue C and distributed to the wireless data transmission link, after the data to be transmitted in the data queue C is completely transmitted, the data queue B is determined to be the second target data queue, the second transmission data is acquired from the data queue B, after the data to be transmitted in the data queue B is completely transmitted, the data queue a is determined to be the second target data queue, and the second transmission data is acquired from the data queue a.

According to the data transmission method and device, the data to be transmitted is divided into the plurality of data queues with different data volume grades, the second transmission data can be firstly obtained from the data queues with low data volume grades, the data with smaller data volume is guaranteed to be transmitted preferentially through the wireless data transmission link, the data opening and data reading efficiency in unit time can be improved based on parallel transmission of the wireless data transmission link for the plurality of transmission channels, the utilization rate of the data transmission channels can be guaranteed, and the data transmission rate in unit time can be improved.

In an exemplary embodiment of the present disclosure, the data queues corresponding to different data volume levels may be in a first-in first-out data queue structure, that is, in response to a data transmission instruction, the first transmission data or the second transmission data is acquired from the head of each data queue, and accordingly, when new data to be transmitted exists, the data is added to the tail of the corresponding data queue according to the data volume of the new data to be transmitted, or when unsuccessfully transmitted data to be processed exists, the data to be processed is added to the tail of the corresponding data queue again.

In an exemplary embodiment of the present disclosure, the data to be transmitted may include private data and public data. The private data is data stored in the private area in the first terminal device, for example, application data of an application installed in the terminal device, for example, application data stored in the directory data, and the private data may also be related data that needs to be transmitted as the private data according to an actual data transmission scenario, and the specific content of the private data is not particularly limited in the embodiment of the present disclosure. The public data may be data stored in a public area, for example, related data stored in a memory card in the first terminal device, and other related data which may be transmitted as public data and not specifically set as private data may be used as the public data in the embodiments of the present disclosure.

Based on the above, the data to be transmitted can be divided into a public data queue and a private data queue according to the type of the data to be transmitted, or related data which needs to be transmitted as private data and exists in a public area can be added into the private data queue to be transmitted as private data according to the actual data transmission requirement, so that the data transmission has more flexibility.

In an exemplary embodiment of the present disclosure, according to a data size class of data size of data to be transmitted in a common data queue, the data to be transmitted in the common data queue may be divided into a plurality of data queues corresponding to the data size class, so as to obtain a plurality of data queues corresponding to the common data queue.

Since the wired data transmission link depends on the mtp (Multi-path transmission) service of the terminal system, the wired data transmission link cannot directly acquire private data in the terminal and needs to encrypt the private data to be used as public data transmission, the embodiment of the disclosure can firstly transmit the public data through the wired data transmission link and firstly transmit the private data through the wireless data transmission link.

The method comprises the steps that a first target data queue is determined from a data queue according to the sequence of data volume levels from high to low, so that first transmission data is acquired from the first target data queue; after the data to be transmitted in the public data queue is transmitted, acquiring first transmission data from the private data queue; or the second transmission data can be acquired from the private data queue, and after the data to be transmitted in the private data queue is transmitted, the second target data queue is determined from the data queue according to the order of the data volume level from low to high so as to acquire the second transmission data from the second target data queue.

Correspondingly, the private data queues can be divided into a plurality of data queues corresponding to different data volume grades according to the data volume size. Wherein the data to be transmitted in the public/private data queues may be divided into a plurality of data queues according to the method shown in fig. 5 or fig. 6, which will not be described in detail.

For example, fig. 7 shows a schematic diagram of acquiring first transmission data and second transmission data according to an exemplary embodiment of the present disclosure, and fig. 7 shows that the public data queue is divided into a data queue a (data amount greater than or equal to 100M) and a data queue B (data amount less than 100M) according to the data amount of data to be transmitted in the public data queue, and the private data queue is divided into a data queue C (data amount greater than or equal to 100M) and D (data amount less than 100M). For the wireless data transmission link, first, the second transmission data is acquired from the data queue D, C according to the order of the data volume level from low to high, if there is no data to be transmitted in the data queues D and C, the second transmission data is acquired from the data queue B, if there is no data to be transmitted in the data queue B, the second transmission data is acquired from the data queue a, that is, for the wireless data transmission link, the private data is acquired first, after all the private data are sent, the public data is acquired according to the order of the data volume from low to high, and the second transmission data is acquired.

For the wired data transmission link, first transmission data is acquired from the data queues corresponding to the public data queues according to the order of the data volume level from high to low, and after all the data to be transmitted in the plurality of data queues corresponding to the public data queues are transmitted, the wired data transmission link performs private data transmission, namely, the first transmission data is acquired from the private data queues according to the order of the data volume level from high to low, namely, the first transmission data is acquired according to the order of the data queues A, B, C and D shown in fig. 7.

In some possible embodiments, in order to ensure that the data amount of the first transmission data sent through the wired data transmission link is greater than the data amount of the second transmission data sent through the wireless data transmission link, when the data amount of the data to be transmitted in the private data queue is greater than the data amount of the data to be transmitted in the public data queue, the first transmission data may be first acquired from a plurality of data queues corresponding to the private data queue, and conversely, the second transmission data may be first acquired from a plurality of data queues corresponding to the public data queue, that is, still ensure that the data amount of the first transmission data is greater than the data amount of the second transmission data.

In an exemplary embodiment of the present disclosure, another implementation of a data transmission policy for data to be transmitted is also provided. In response to the data transmission instruction, acquiring the first transmission data and the second transmission data of the data to be transmitted may include the following steps S810 to S820:

Step 810, the data to be transmitted is ordered according to the order of the data size from large to small, so as to obtain a data queue.

In step S820, the first transmission data is acquired from the head of the data queue, and the second transmission data is acquired from the tail of the data queue.

In an exemplary embodiment of the present disclosure, data to be transmitted may be ordered according to an order of from large to small data amounts, so as to obtain a data queue, and first transmission data may be obtained from a head of the data queue, and second transmission data may be obtained from a tail of the data queue, so as to ensure that data to be transmitted with a larger data amount is preferentially selected as the first transmission data, and data to be transmitted with a smaller data amount is selected as the second transmission data. Fig. 9 is a schematic diagram of acquiring first/second transmission data from ordered data to be transmitted according to an embodiment of the disclosure, where the ordered data queues are x1, x2, x3 … …, that is, the first transmission data and the second transmission data are acquired from the head and tail of the queue respectively.

In another exemplary embodiment, the data to be transmitted may be further sorted according to the order of the data volume from small to large, so as to obtain a data queue, obtain the second transmission data from the head of the data queue, and obtain the first transmission data from the tail of the data queue, so that it is ensured that the data to be transmitted with a larger data volume is preferentially selected as the first transmission data, and the data to be transmitted with a smaller data volume is selected as the second transmission data.

The data to be transmitted is sequenced according to the data quantity to obtain a data queue, and the first transmission data can be transmitted by the wired data transmission link and the second transmission data can be transmitted by the wireless data transmission link under the condition that more data queues are not required to be divided.

In an exemplary embodiment of the present disclosure, the private data may be encrypted before the first transmission data and the second transmission data in the data to be transmitted are acquired in response to the data transmission instruction, and the encrypted private data and the public data are used as the data to be transmitted, so that the security of the private data is ensured, and the encrypted private data and the public data can be transmitted in the same data sending policy.

In an exemplary embodiment of the present disclosure, in a process of transmitting first transmission data and second transmission data to a second terminal device through a wired data transmission link and a wireless data transmission link, when a transmission abnormality occurs in certain data to be transmitted, the data to be transmitted is rejoined in a corresponding data queue. When the transmission of the first transmission data by the wired data transmission link fails, the first transmission data is added into the corresponding data queue again; and/or when the wireless data transmission link fails to transmit the second transmission data, the second transmission data is added into the corresponding data queue again.

And under the condition that the data to be transmitted is distributed to the data queues corresponding to different data volume grades according to the data volume of the data to be transmitted, if the first transmission data/the second transmission data are abnormal in transmission, the first transmission data/the second transmission data are added into the corresponding data queues again according to the first transmission data/the second data volume of the abnormal transmission. For example, if the first transmission data belongs to the data queue a before transmission, the data amount according to the first transmission data is added to the data queue a again after transmission abnormality. For example, when the data queue a is first-in first-out, then the end of the queue is added to the data queue a.

Under the condition that a data queue is obtained according to the sequence of the data volume from large to small, if the first transmission data/the second transmission data are abnormal in transmission, the first data/the second transmission data to be transmitted are added to the corresponding positions in the ordered data queue again according to the data volume of the first transmission data/the second transmission data with abnormal transmission, and the ordered data queue is ensured to be arranged according to the sequence of the data volume from large to small (or from small to large).

According to the data transmission method and device, in the data transmission process, the data to be processed with abnormal transmission is added to the corresponding data queue again, so that the influence on the normal operation of the whole data transmission due to the abnormal transmission of the individual data to be transmitted is avoided, the omission of any data to be transmitted is avoided, and the integrity of the data transmission is ensured.

It should be noted that, in an exemplary embodiment, the data queue or the position to which the data to be transmitted belongs may also be adjusted in response to the transmission level adjustment operation of the user, so that the order of data transmission accords with the user expectation and the user experience is good under the condition of ensuring the utilization rate of the transmission link.

In an exemplary embodiment of the present disclosure, in order to increase the data transmission rate, step S220 may further include: and acquiring first transmission data and second transmission data in the data to be transmitted according to the data transmission rates of the wired data transmission link and the wireless data transmission link.

The first transmission rate of the wired data transmission link may be acquired, and the second transmission rate of the wireless data transmission link may be acquired, and if the first transmission rate is greater than the second transmission rate, the first transmission data may be sent to the second terminal device through the wired data transmission link, and the second transmission data may be sent to the second terminal device through the wireless data transmission link. Correspondingly, if the first transmission rate is smaller than the second transmission rate, the second transmission data is sent to the second terminal device through the wired data transmission link, and the first transmission data is sent to the second terminal device through the wireless data transmission link.

For example, with continued reference to fig. 7, when there is only data to be transmitted that contains an incomplete transmission in the data queue a, the first transmission data and the second transmission data may be acquired from the data queue a according to the data transmission rates of the wired data transmission link and the wireless data transmission link. For example, if the current wired data transmission link is idle, the first transmission data can be acquired from the data queue a and transmitted through the wired data transmission link, and when the wireless data transmission link finishes the transmission of the current second transmission data, the second transmission data is acquired from the data queue a immediately and is performed through the wireless data transmission link, and when the wired/wireless data transmission links are idle, according to the current data transmission rate, the data transmission rates in the wired data transmission link and the wireless data transmission link are higher, the first transmission data with large data quantity in the data to be transmitted is transmitted first, and the second transmission data is transmitted by the other data transmission link, so that the wired data transmission link and the wireless data transmission link are ensured to have no idle condition, and the data transmission efficiency is ensured.

In the actual transmission process, if the data size of the data to be transmitted is smaller than the first data size threshold, the exemplary embodiment of the disclosure further provides an implementation manner of data packaging and sending: and combining the first target data to be transmitted in the data to be transmitted to generate a data packet with the data volume being greater than or equal to a first data volume threshold value, and taking the data packet as first transmission data so as to send the data packet to the second terminal equipment through a wired data transmission link. The first target data to be transmitted may select a portion of the data to be transmitted from the data to be transmitted according to current data processing capabilities of the current wired data transmission link and the wireless data transmission link.

If the data to be transmitted are smaller than 100M, a part of the data to be transmitted can be selected from the data to be transmitted, combined, packed to generate a data packet with the data amount larger than or equal to 100M, and transmitted through the wired data transmission link, and other unpacked data to be transmitted continue to be transmitted through the wireless data transmission link, so that the problem of low channel utilization caused by the fact that the wired data transmission link transmits files with smaller data amount is avoided, the channel utilization of the wired data transmission link is improved, the data to be transmitted with smaller data amount is processed in parallel through the wired/wireless data transmission link, and the data transmission rate is improved.

In the actual transmission process, there may be a case that the data amount of the data to be transmitted is greater than the second data amount threshold, and the exemplary embodiment of the present disclosure further provides an implementation manner of data splitting and sending: and dividing the second target data to be transmitted in the data to be transmitted into a plurality of split sub-data, and transmitting the split sub-data to the second terminal equipment through a wireless data transmission link. The second target data to be transmitted may select a portion of the data to be transmitted from the data to be transmitted according to current data processing capabilities of the current wired data transmission link and the wireless data transmission link.

The second target data to be transmitted may be split into a plurality of split sub-data, and the split sub-data belonging to the same second target data to be transmitted may be set with an associated identifier, so that after the split sub-data are sent to the second terminal device, the second terminal device may combine the split sub-data belonging to the same second target data to be transmitted according to the associated identifier.

According to the data transmission method and device, the data to be transmitted can be dynamically combined or split according to the data size of the data to be transmitted, the wired data transmission link can be used for preferentially processing the data with larger data size, the wireless data transmission link is used for preferentially processing the data with smaller data size, the condition that the wired data transmission link and the wireless data transmission link are free or wait to transmit is avoided, and the data transmission rate is improved.

In an exemplary embodiment of the present disclosure, in order to improve robustness of data transmission, transmitting, in parallel, first transmission data and second transmission data to a second terminal device by using a wired data transmission link and a wireless data transmission link for cooperative transmission of data to be transmitted may at least include: when the wired data transmission link is abnormal, transmitting the first transmission data to the second terminal equipment through the wireless transmission link; or when the wireless data transmission link is abnormal, transmitting the second transmission data to the second terminal equipment through the wired transmission link. That is, in the data transmission process, the transmission is interrupted due to the abnormality of one transmission link in the wired data transmission link or the wireless data transmission link, the other transmission link can still normally perform data transmission, and the other transmission link can be used for sending the remaining data to be transmitted to the second terminal device, so that the robustness and stability of the data transmission are ensured.

In an exemplary embodiment of the present disclosure, after a wired data transmission link is established between a first terminal device and a second terminal device, if the second terminal device supplies power to the first terminal device, the power supply includes two parts: power consumption for data transmission and power consumption for charging the first terminal device. In order to ensure enough power consumption for data transmission, the embodiment of the disclosure stops the charging behavior between the first terminal device and the second terminal device based on the wired data transmission link, avoids the electric quantity loss and heating caused by charging the second terminal device to the first terminal device, ensures that the second terminal device is in low electric quantity to cause data transmission interruption, improves the stability of data transmission, and also avoids the problems of data loss and the like caused by the data transmission interruption.

In an exemplary embodiment of the present disclosure, in order to ensure stability of a data transmission process, if at least one of the first terminal device and the second terminal device has a power value lower than a preset power threshold, sending data to be transmitted to the second terminal device is stopped. For example, the preset electric quantity threshold is 20% of the electric quantity of the terminal equipment, if the electric quantity of the second terminal equipment is lower than 20%, the sending of the data to be transmitted to the second terminal equipment is stopped, and the data loss and the like caused by the interruption of transmission are avoided. The preset power threshold may be a predetermined value of the terminal device, or may be set by a user of the terminal device before the data transmission operation.

By way of example, fig. 10 shows a process flow diagram of a wired data transmission process according to an exemplary embodiment of the present disclosure. As shown in fig. 10, taking a terminal device of an android system as an example, a wired data transmission link between a first terminal device and a second terminal device is established, and data to be transmitted is divided into a data queue a, a data queue B and a data queue C with data volume levels from high to low, where the process includes:

In step S1020, the first terminal device notifies the second terminal device to read the first transmission data through the wired data transmission link.

In step S1030, the second terminal device reads the first transmission data received through the wired data transmission link through an MTP (custom extension protocol based on picture transmission protocol) driving interface of the android platform.

In step S1040, the second terminal device may verify the integrity of the received first transmission data, and if the first transmission data is incomplete and the current power is lower than 20%, or the wired transmission link is disconnected, the data transmission is interrupted, and the incomplete first transmission data is deleted.

Step S1050, the first terminal device receives the data transmission result sent by the second terminal device, and if the sending is successful, the steps S1010 to S1040 are repeatedly executed.

In step S1060, if the transmission fails, the first transmission data with failed transmission is added to the corresponding data queue again. The manner of re-joining to the corresponding data queue is described in the above section, and will not be described in detail here.

In step S1070, if the power of the first terminal device is lower than 20% or the wired data transmission link is disconnected, the sending of the first transmission data to the second terminal device is stopped.

According to the data transmission method, the data is transmitted in a wired data transmission link mode, the problems that the wireless data transmission link is easily affected by physical environment and the transmission rate is unstable are solved, the data is transmitted in a wireless data transmission link mode, the data is transmitted in parallel through a plurality of transmission channels, the problems that the wired data transmission link is easily limited by the transmission rate of a universal serial bus and the like are solved, the data transmission efficiency between terminal equipment is improved, and the user experience is improved through the mutual complementation of the transmission performance between the two channels.
