Description

Data transmission method and corresponding terminal

The present application claims priority from chinese patent application filed on 2018, 11/01/h, with chinese patent office, application number 201811310002.5, entitled "method for parallel transmission between terminals," the entire contents of which are incorporated herein by reference.

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a parallel data transmission method between terminals and a corresponding terminal.

Background

With the diversified development of the functions of the intelligent terminal, the types of data storage which can be supported in the intelligent terminal are more and more diversified, and the amount of stored data is more and more large. In this way, when a terminal user needs to perform data transmission or data backup, for example, the user replaces the terminal, the data (such as pictures, videos, office files, audios, and address books) stored in the old terminal needs to be migrated to a new terminal, and for example, when the terminal has a problem and needs to be repaired, or when an operating system needs to be successfully and newly installed, the data backup stored in the terminal needs to be migrated to a storage medium. The migration speed of data can directly affect the user experience.

In order to complete the data migration, one possible solution in the prior art is to use a data transmission method in the prior art as shown in fig. 1. The user may install the cell phone cloning software or the switch assistant software in the originating terminal and the terminating terminal, scan the two-dimensional code generated in the cell phone cloning software or the switch assistant software installed on the terminating terminal by using a functional module (e.g., "scan") for scanning the two-dimensional code installed on the originating terminal or the switch assistant software installed on the terminating terminal, establish a WiFi P2P link between the originating terminal and the terminating terminal, and implement data migration from the originating terminal to the terminating terminal through the WiFi P2P link. However, the method has limited data migration rate, long time consumption when the user data volume is large, and low reliability, and once an unexpected situation (such as two-machine distance pulling) causes the disconnection of the WiFi link.

In another possible solution, as shown in fig. 2, a second example of a data transmission method in the prior art is shown. Data migration may be implemented using a data transmission line (e.g., Universal Serial Bus (USB)), but the method still has a limited migration rate, is time consuming when the user data volume is large, and still has low reliability, and if an unexpected situation (e.g., a data transmission line interface contact is problematic), the migration is interrupted, which greatly affects the user experience.

In another possible solution, as shown in fig. 3, a data transmission method in the prior art is exemplified by three. The user logs in the cloud account at the sending end, uploads the data to be transmitted to the cloud server for storage, then logs in the cloud account at the receiving end, and downloads the data to the receiving end, so that data migration is achieved. However, such a method is highly dependent on internet access services and cloud servers, and fails once a network is in trouble or a server is down, and if a user uploads and downloads data using a cellular network, additional traffic is generated, which may cause additional cost and affect user satisfaction.

in other embodiments, the data to be transmitted may also be determined by the first terminal 100, for example, when the first terminal 100 needs to reinstall the system, the first terminal 100 may automatically default to use all data stored in the first terminal 100 as the data to be transmitted, and the method and the manner for determining the data to be transmitted are not limited in this embodiment of the present application. It should be noted that step 604 has no fixed timing limitation with step 602 and step 603, and step 604 may precede step 602 or step 603. In addition, the determination of the transmission strategy and the determination of the data to be transmitted also have no fixed time sequence limit, and the transmission strategy can be determined first, and then the data to be transmitted can be determined.

The transmission policy may include, but is not limited to, a time saving policy and a power saving policy. Optionally, the transmission policy may be selected by a user, for example, the user may select a transmission policy according to his own will, where the transmission policy is used to inform the first terminal 100 which performance in the data transmission process the user pays more attention to, for example, if the user pays more attention to the amount of power consumption, the power saving policy may be selected; if the user focuses more on the transmission speed, the time-saving policy may be selected, and of course, other transmission policies with other performance considerations may also be considered, which is not limited in the embodiment of the present application.

As shown in fig. 11, which is a schematic view of a transmission policy determination interface according to an embodiment of the present application, as shown in fig. 11, the selection interface may be displayed in a floating manner on the basis of the interface after the data to be transmitted is determined in fig. 10.

Optionally, the transmission policy may also be determined by the first terminal 100, specifically, the first terminal 100 may determine according to the terminal information of the first terminal 100, for example, if the electric quantity of the first terminal is less than a preset threshold, the first terminal 100 may determine to select the power saving policy, and if the electric quantity of the first terminal is greater than the preset threshold, the first terminal 100 may determine to select the time saving policy.

Optionally, the transmission policy may be adjusted according to a specific situation of data transmission during data transmission, for example, whether the transmission policy needs to be changed is selected according to an electric power consumption situation and a data transmission speed during data transmission.

Different transmission strategies correspond to different data transmission links, and for example, if the transmission strategy is determined to be a time-saving strategy, the data transmission links for transmitting the data to be transmitted may be determined to be WiFi and the cellular link D2D. The correspondence may be preset, and specifically, the transmission policies may be ranked according to various performances of each data transmission link, for example, the transmission policies are ranked according to the power consumption and the transmission speed, and the transmission policies are referred to the rankings according to performances concerned by different transmission policies, for example, the first three ranked transmission speeds are used as data transmission links corresponding to the time-saving policy.

Optionally, the corresponding relationship between the transmission policy and the data transmission link may receive user-defined settings and modifications of the user.

Optionally, after the first terminal 100 determines the transmission policy, the first terminal 100 may further pop up to remind the user whether to determine to start data transmission.

605. The processor 501 of the first terminal 100 executes the parsing instructions in the memory 503 to divide the data to be transmitted into at least two data packets, which may include: a first data packet and a second data packet.

The first terminal 100 divides the data to be transmitted into a plurality of data packets according to a specific segmentation method (for example, an equal division method), and the determined available transmission links jointly carry each data packet, thereby completing the transmission of each data packet in sequence.

Because the rate and energy consumption of each transmission link may be changed by environmental influences at different times (wireless interference and noise, transmission distance change, etc.), in order to dynamically adjust the data amount on each available transmission link according to the specific situation of data transmission during data transmission, by segmenting the data to be transmitted and transmitting the data accordingly, the data amount on each data transmission link during next data transmission can be adjusted according to the transmission situation of the segment of data after each segment of data is transmitted, and the corresponding transmission strategy and available transmission links during next data transmission can be flexibly adjusted.

Optionally, when segmenting the data to be transmitted, the data may be equally divided into a plurality of segments, or according to any other allocation method, which is not limited in the embodiment of the present application.

Optionally, the first terminal 100 may determine, according to the first terminal information and the second terminal information, a transmission link that is commonly supported by the first terminal 100 and the second terminal 110; an available transmission link is then determined from the transmission links commonly supported by the first terminal 100 and the second terminal 110 according to the transmission policy. Specifically, the commonly supported transmission link refers to a transmission link that is commonly supported by both hardware and software (i.e., supported protocol information) of the first terminal 100 and the second terminal 110.

Illustratively, the hardware information displays of the first terminal 100 and the second terminal 110 both support USB, but the protocol information displays that the first terminal 100 supports USB2.0 and the second terminal 110 supports USB3.0, so data cannot be transmitted to the second terminal 110 through USB3.0 because the hardware of the first terminal 100 does not support USB3.0, and at this time, the hardware of the second terminal 110 can be compatible with the low-version USB2.0, so the first terminal 100 can transmit data to the second terminal 110 through USB 2.0.

Optionally, after determining an available transmission link according to the first terminal information, the second terminal information, and the transmission policy, the method may further include: the processor 501 of the first terminal 100 executes the notification instructions in the memory 503 to alert the user to assist in establishing the available data transmission link.

For example, the first terminal 100 may remind the user to assist in establishing the data transmission link through various manners such as pop-up window notification and voice notification, which is not limited in the embodiment of the present invention.

For example, as described above, if it is determined that the USB2.0 is an available transmission link, the first terminal 100 may further prompt the user to manually connect the USB data line between the first terminal 100 and the second terminal 110 to assist in turning on the transmission link. For example, after determining that the data transmission link is WiFi transmission, the first terminal 100 and the second terminal 110 may prompt the user with voice to authorize the first terminal 100 and the second terminal 110, so that the first terminal 100 and the second terminal 110 turn on the WiFi switch, and optionally, the first terminal 100 and the second terminal 110 may also prompt the user with voice to turn on the WiFi switch manually by the first terminal 100 and the second terminal 110.

Fig. 12 is a schematic diagram of a prompt for establishing a transmission link according to an embodiment of the present application. As shown in fig. 12, the first terminal 100 determines that the available transmission links are USB3.0 and WiFi, and the pop-up window reminds the user that the links that need to be assisted to be turned on are USB3.0 and WiFi and reminds the user that the user needs to check whether the available transmission links are turned on.

Optionally, the first terminal 100 may also determine a preferred data transmission link of the first terminal 100 according to the terminal information of the first terminal 100 and the determined transmission policy, determine a preferred data transmission link of the second terminal 110 according to the terminal information of the second terminal 110 and the determined transmission policy, and then determine at least one preferred data transmission link commonly supported by the first terminal 100 and the second terminal 110 as a link for performing data transmission.

607. The processor 501 of the first terminal 100 executes the analysis instructions in the memory 503 to determine the data of the first data packet that needs to be transmitted by each of the available transmission links when transmitting the first data packet.
