Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent terminals, in particular to a data transmission method and an electronic device. BACKGROUND

[0002] With the rapid development of technology, the types of intelligent terminals are increasing. For example, according to the classification of device types, the intelligent terminals can include mobile phones, tablets, computers, vehicle-mounted devices, smart homes, fitness devices, televisions, large screens, etc. According to different application scenarios, different intelligent terminals can be applied to office, home, sports, travel, education, etc. Different intelligent terminals can store data respectively, and therefore, in order to provide a good user experience, data transmission is needed between different intelligent terminals to complete information synchronization.

[0003] For example, when a user replaces a new device or adds a new device, the user needs to transmit data (such as application packages, pictures, or files, etc.) in the old device to the new device to realize information synchronization between the new device and the old device.

[0004] The existing data transmission method one is to use a third-party server (such as a cloud, etc.). The old device backs up and transmits data to the cloud by logging in to the cloud account, and then the new device downloads and installs application programs and recovers data by logging in to the same cloud account to complete information synchronization between the new device and the old device. The disadvantage of the existing data transmission method one is that data transmission between the new device and the old device needs to use a third-party server, and logging in to the same server account is needed to complete information synchronization. Moreover, cloud backup has problems such as slow speed, long time consumption, and large amount of traffic consumption. If the new device and the old device log in to different third-party servers, or log in to different server accounts, or do not log in to the third server, the new device and the old device cannot complete data transmission, and thus information synchronization cannot be realized.

[0005] The existing data transmission method two is to establish a one-to-one connection between the new device and the old device. The user operates the old device to select data to be transmitted in the old device, so that the old device transmits the selected data to the new device, and the new device installs application programs and recovers data to complete information synchronization between the new device and the old device. The disadvantage of the existing data transmission method two is that the new device and the old device can only complete one-to-one data transmission, and the user needs to operate the old device to select data to be transmitted and transmit the data to the new device. If some hardware (such as a key or a screen) of the old device is damaged, the user cannot operate the old device, so data cannot be transmitted to the new device, and thus information synchronization cannot be realized.

[0072] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0073] like Figure 1 As shown, one existing data transmission method relies on a third-party server (such as a cloud service). The old device logs into its cloud account, backs up its data, and transmits it to the cloud. Then, the new device logs into the same cloud account, downloads the data, installs applications, and restores the data to synchronize information between the new and old devices. The drawback of this method is that data transmission between the new and old devices requires a third-party server and the same server account for synchronization. Furthermore, cloud backups are slow, time-consuming, and consume significant bandwidth. If the new and old devices log into different third-party servers, different server accounts, or do not log into a third-party server, data transmission between them is impossible, thus preventing information synchronization.

[0074] like Figure 2As shown, the existing data transmission method two involves establishing a one-to-one connection between the new and old devices. The user operates the old device to select the data to be transmitted, causing the old device to transfer the selected data to the new device. The new device then installs the application and restores the data, thus completing the information synchronization between the new and old devices. The drawback of this existing data transmission method two is that it can only complete one-to-one data transmission between the new and old devices. Furthermore, the user needs to operate the old device to select the data to be transmitted to the new device. If some hardware on the old device (such as buttons or the screen) is damaged, the user will be unable to operate the old device, preventing data transmission to the new device and thus hindering information synchronization.

[0075] Therefore, this application proposes a data transmission method and an electronic device, which can transmit data (such as application packages, files or pictures) with at least one second device without relying on a third-party server (such as the cloud) or requiring the user to operate the second device, thus providing a good user experience.

[0076] Figure 3 A flowchart of one embodiment of the data transmission method of this application is shown below. Figure 3 As shown, the above data transmission method is applied to a first device, wherein the first device establishes a connection with at least one second device, and the method includes:

[0077] S101. Send a first request to the second device, causing the second device to send first information based on the first request, wherein the first information includes the application identifier and device identifier of the second device.

[0078] The first device and the second device may include mobile terminals (phones), smart screens, tablets, computers, smart home devices, fitness equipment, televisions, large screens, drones, intelligent connected vehicles (ICVs), smart cars, or in-vehicle equipment, etc. The first device and the second device may be the same device or different devices, and multiple second devices may be the same device or different devices. For example, the first device may be a mobile phone, and the second devices may be mobile phones, tablets, televisions, large screens, etc.

[0079] The first device can establish connections with multiple second devices, and the connection methods can include wireless connections such as Wi-Fi, Bluetooth, local area network, broadcast, and antenna, or wired connections. In step S101, the first device can send the first request to multiple second devices, and the first request can include a message from the first device requesting data transmission with the second devices, so as to realize one-to-one or one-to-many data transmission between the first device and multiple second devices.

[0080] It is worth mentioning that, in this embodiment, the method can complete the data transmission between the first device and the second device without relying on a third-party server (such as the cloud).

[0081] S102, Receive the first information sent by the second device.

[0082] In step S102, the first device can receive the first information sent by multiple second devices. The application identifier can be used to identify the name of the application of the second device, and the device identifier can be used to identify the device name or ID of the second device. For example, the second devices may include device A, device B, and device C. Device A may include application A1, application A2, and application A3. Device B may include application B1 and application B2. Device C may include application C1 and application C2. The first information sent by device A includes the application identifiers of application A1, application A2, and application A3 of device A and the device identifier of device A. The first information sent by device B may include the application identifiers of application B1 and application B2 of device B and the device identifier of device B. The first information sent by device C may include the application identifiers of application C1 and application C2 of device C and the device identifier of device C.

[0083] It is worth mentioning that the first device can transmit data with multiple second devices via wireless or Bluetooth, and the first device can store the application identifier and device identifier of all the second devices to enable selective data transmission.

[0084] S103. Based on the first information, a second request is sent to the second device corresponding to the device identifier, so that the second device sends the application package corresponding to the application identifier to the first device based on the second request, so as to complete the data transmission between the first device and the second device.

[0085] In step S103, the first device may send second requests to multiple second devices, causing each of the second devices to send corresponding application packages to the first device, thereby enabling the first device to complete data transmission with each of the second devices. The second request may include a message from the first device requesting the second devices to send application packages to the first device. For example, based on the device identifier of device A, the first device sends a second request to device A, causing device A to send application packages for applications A1, A2, and A3 to the first device; based on the device identifier of device B, the first device sends a second request to device B, causing device B to send application packages for applications B1 and B2 to the first device; based on the device identifier of device C, the first device sends a second request to device C, causing device C to send application packages for applications C1 and C2 to the first device, thereby enabling data transmission between the first device and devices A, B, and C.

[0086] In this embodiment, as Figure 4 As shown, the first device and multiple second devices form a network system via wireless, Bluetooth, or other means. The method may include:

[0087] S901. Receive first information sent by the second device, wherein the first information includes the application identifier of the second device;

[0088] S902. Based on the first information, send a first request to the second device, wherein the first request is used to request the second device to send an application package corresponding to the application identifier to the first device;

[0089] S903: Receive the application package corresponding to the application identifier sent by the second device.

[0090] Preferably, both the first device and each second device in the network system store a distributed database. This distributed database stores first information about each device in the network system, which may include application identifiers or device identifiers. For example, after receiving first information sent by one or more second devices, the first device stores the received first information in the distributed database. It is understood that there is a mapping relationship between the device identifier and the application identifier of the second device, such as device identifier + application identifier. For instance, the device identifier can be used to identify the name or ID of the second device, and the application identifier can be used to identify the application name or ID of the second device corresponding to that device identifier.

[0091] like Figure 5 As shown, the distributed database of the first device stores multiple pieces of first information about the second devices (such as application identifiers and device identifiers). For example, the distributed database stores multiple pieces of first information corresponding to device A, multiple pieces of first information corresponding to device B, and multiple pieces of first information corresponding to device C. The multiple pieces of first information corresponding to device A may include device identifier a + application identifier a1, device identifier a + application identifier a2; the multiple pieces of first information corresponding to device B may include device identifier b + application identifier b1, device identifier b + application identifier b2; and the multiple pieces of first information corresponding to device C may include device identifier c + application identifier c1, device identifier c + application identifier c2. It can be understood that application identifier a1, application identifier b1, and application identifier c1 can identify the name or ID of the same application, and application identifier a2, application identifier b2, and application identifier c2 can identify the name or ID of the same application, thus representing the same application (which may have different versions) on different devices.

[0092] like Figure 6 As shown, a new device (such as the first device) and an old device (such as the second device) can establish a connection to form a network system to complete data transmission between the new and old devices. Both the new and old devices contain a distributed database. The distributed database of the new device stores one or more application identifiers of the old device, and the distributed database of the old device stores one or more application identifiers of the new device. Furthermore, both the new and old devices include a packet management module and an application program. The packet management module is used to receive and send first information and application packets, store the received first information in the distributed database, and complete application installation and data recovery.

[0093] For example, the package management module of the old device reads the application identifier from the application's fields and sends the application identifier to the package management module of the new device. The package management module of the new device receives the application identifier from the old device and stores it in the distributed database of the new device. The package management module of the new device can also send a first request to the old device based on the application identifier of the old device, so that the package management module of the old device can send the corresponding application package to the new device based on the first request. After receiving the application package, the package management module of the new device completes the installation of the application and data recovery, etc.

[0094] like Figure 7As shown, a first device and multiple second devices can establish a network system to complete data transmission between the devices. The first device and the multiple second devices, such as device A, device B, and device C, can each include a distributed database, an application program, and a packet management module. Therefore, the distributed database of the first device can store the application identifiers and device identifiers of the multiple second devices.

[0095] Further, step S902 may include:

[0096] S911, Display multiple application identifiers and device identifiers of the second device;

[0097] S912, In response to the user selection operation, select the first target device identifier and the first target application identifier from a plurality of application identifiers and device identifiers of the second device;

[0098] S913. Send a first request to the second device corresponding to the first target device identifier, the first request being used to request the second device corresponding to the first target device identifier to send an application package corresponding to the first target application identifier to the first device.

[0099] In other words, multiple application identifiers and device identifiers of the second devices can be displayed on the touch screen of the first device. The user can operate on the touch screen of the first device to select the first target device identifier and the first target application identifier to be cloned. The first device then requests the second device corresponding to the first target device identifier to download the application package corresponding to the first target application identifier.

[0100] In one possible implementation, the second device backs up the application package before sending it to the first device. That is, the second device can back up and store the application package to prevent data loss.

[0101] It should be noted that the first device may include a package management system for managing the application packages, such as installing applications or performing data recovery, etc., without limitation.

[0102] It is worth mentioning that the method further includes installing an application and recovering data based on the application package. In other words, the first device can install an application and recover data based on the application package, thereby achieving information synchronization.

[0103] It is understood that in this method, the user does not need to operate the second device. Furthermore, the user may also not need to operate the first device, and the first device may not need to prompt the user during the data transmission process between the first device and the second device, thus achieving silent transmission between the first device and the second device.

[0104] In one possible implementation, as shown in Figure 10(a), before step S103, the method further includes displaying the first information, responding to the user's selection operation, and determining the target application of the target device to be transmitted in the first information. The first information can be displayed in the first device in the form of a list, text, or sequence. The target application of the target device may include the application of the second device selected by the user in the first information. For example, the user can select application A1 and application A3 of device A and application C1 of device C in the first information, that is, the target applications of the target device are application A1 and application A3 of device A and application C1 of device C. The first device sends a second request to device A and device C respectively, so that device A sends the application packages of application A1 and application A3 to the first device, and device C sends the application package of application C1 to the first device, so that the first device installs application A1, application A3, and application C1 respectively according to the application packages of application A1, application A3, and application C1, and restores the corresponding data to complete information synchronization.

[0105] Those skilled in the art should understand that the first device and the second device can also transmit data such as files or pictures, which should all fall within the protection scope of this application.

[0106] In one possible implementation, the first request includes device type information of the first device, the second device includes compatibility information between the application and the device type, and the first information sent by the second device is determined based on the device type of the first device and the compatibility information.

[0107] In this embodiment, the first device stores device type information, which may include the device type of a mobile terminal (phone), smart screen, tablet, computer, smart home device, fitness equipment, television, large screen, drone, intelligent connected vehicle (ICV), smart car, or in-vehicle equipment. The second device stores compatibility information between applications and device types, which may include the device types that the applications in the second device are compatible with. The first information may include the application identifier and device identifier of the second device that are compatible with the first device. In other words, the second device determines whether its applications are compatible with the first device based on the compatibility information and the device type information of the first device, thereby determining the first information.

[0108] For example, as shown in Figure 10(b), based on the compatibility information and the device type information of the first device, device A determines that applications A1 and A2 of device A are compatible with the first device; device B determines that application B2 of device B is compatible with the first device; and device C determines that application C1 of device C is compatible with the first device. Then, the first information includes the application identifiers of applications A1 and A2 of device A and the device identifier of device A; the application identifier of application B2 of device B and the device identifier of device B; and the application identifier of application C1 of device C and the device identifier of device B. In step S103, device A sends the application packages of applications A1 and A2 to the first device; device B sends the application package of application B2 to the first device; and device C sends the application package of application C1 to the first device, so that the first device can install applications A1, A2, B2, and C1 and perform corresponding data recovery.

[0109] It is understood that the compatibility information may include a preset field added to the application data package during the application development phase of the application, the preset field being used to indicate the types of devices that the application is compatible with.

[0110] In other words, step S901 may include:

[0111] S921. Send the device type of the first device to the second device;

[0112] S922, Receive first information sent by the second device, wherein the first information includes an application identifier compatible with the device type of the first device.

[0113] In other words, the second device stores compatibility information between the application and the device type. Before the second device sends the first information to the first device, the first device first sends its device type to the second device. Based on the device type and compatibility information, the second device sends the application identifier of the application that is compatible with the first device to the first device, in order to avoid the first device downloading an incompatible application and wasting resources.

[0114] One possible implementation is as follows: Figure 8 As shown, the first device includes device type information, and the first information also includes compatibility information between the application and the device type. After receiving the first information sent by the second device, the method further includes:

[0115] S201. Based on the compatibility information and the device type information, determine the application of the second device in the first information, and then determine and display the second information.

[0116] In this embodiment, the first device stores device type information. The second device stores compatibility information between applications and device types, which may include device types that the applications in the second device are compatible with. In step S201, the first device determines whether the applications in the second device are compatible with the first device based on the compatibility information in the first information and the device type information of the first device, thereby determining the second information.

[0117] For example, based on the compatibility information and the device type information of the first device, the first device determines that application A3 of device A, application B1 of device B, and application C2 of device C are compatible with the first device. In step S103, device A sends the application package of application A3 to the first device, device B sends the application package of application B1 to the first device, and device C sends the application package of application C2 to the first device, so that the first device can install application A3, application B1, and application C2 and perform corresponding data recovery.

[0118] The second information can be displayed on the first device in the form of a list, text, or sequence. The first device can display the names of the second device and its applications to meet the user's selection needs. For example, the first device can display the names of device A and its application A3, device B and its application B1, and device C and its application C2.

[0119] In other words, step S902 may include:

[0120] S931. Based on the compatibility information, determine whether the application of the second device is compatible with the device type of the first device;

[0121] S932. If the application of the second device is compatible with the device type of the first device, a first request is sent to the second device, wherein the first request is used to request the second device to send an application package corresponding to the application identifier that is compatible with the device type of the first device to the first device.

[0122] In other words, the first information received by the first device also includes compatibility information between the second device's application and device type, used to determine whether the second device's application is compatible with the first device. If the second device's application is incompatible with the first device, the first device does not need to send a first request to the second device, avoiding downloading an incompatible application and wasting resources.

[0123] In one possible implementation, before sending the second request to the second device corresponding to the device identifier, the method further includes:

[0124] S202, In response to the user's selection operation, determine the selected target application in the second information.

[0125] For example, as shown in Figure 10(c), when a user selects application A3 on device A and application C2 on device C, the first device determines in the second information that the selected target application corresponds to application A3 on device A and application C2 on device C. In step S103, based on the selected target application determined in the second information, the first device sends a second request to the corresponding second device, so that the second device sends the application package of the corresponding target application to the first device, so that the first device can install the target application and perform data recovery. For example, in step S103, the first device sends a second request to device A and device C, so that device A sends the application package of application A3 to the first device, and device C sends the application package of application C2 to the first device, so that the first device can install application A3 and application C2 and recover the corresponding data.

[0126] It is understood that the user's selection operation may include clicking the icon or name of the corresponding application of the second device on the screen of the first device, or other operation methods such as voice, gesture, etc., which are not limited here.

[0127] One possible implementation is as follows: Figure 9 As shown, the first information also includes the application version, and after receiving the first information sent by the second device, the method further includes:

[0128] S301. Based on the version, determine the same application of multiple second devices in the first information, and determine and display the third information.

[0129] For example, devices A, B, and C all include the same application m and the same application n, and the versions of the same application m and the same application n of devices A, B, and C are different, with the version of application m on device C and application n on device A being the highest. The first information may include the versions of the same application m and the same application n of devices A, B, and C, respectively. In step S301, the first device determines that the version of application m on device C is the highest and the version of application n on device A is the highest, and then determines the third information, wherein the third information includes the application identifier of application m on device C and the device identifier of device C, and the application identifier of application n on device A and the device identifier of device A. The first device may display information such as the names of application m on device C and application n on device A to meet the user's selection needs. In step S103, the first device sends a second request to both device A and device C, so that device A sends the application package of application n to the first device, and device C sends the application package of application m to the first device, so that the first device can install the highest version of application m and application n and restore data.

[0130] In other words, step S902 may include:

[0131] S941. Compare the same application version of multiple second devices to determine the second target device identifier and the second target application identifier corresponding to the application version, wherein the application version of the second device corresponding to the second target device identifier is the highest.

[0132] S942. Send a first request to the second device corresponding to the second target device identifier, the first request being used to request the second device corresponding to the second target device identifier to send an application package corresponding to the second target application identifier to the first device.

[0133] In other words, the first information may also include application versions and device identifiers of multiple second devices. For example, if device A, device B, and device C all include the same application m, and device C has the highest version of application m, then device C is the second target device, application m is the second target application, and therefore, the first device can download the application package of application m from device C and complete the installation of the application package and data recovery, etc.

[0134] In one possible implementation, before sending the second request to the second device corresponding to the device identifier, the method further includes:

[0135] S302. In response to the user's selection operation, determine the selected target application from the third information.

[0136] For example, as shown in Figure 10(d), when a user selects application m on device C, the first device determines from the third information that the selected target application corresponds to application m on device C. In step S103, based on the selected target application determined from the third information, the first device sends a second request to the corresponding second device, so that the second device sends the application package of the corresponding target application to the first device, so that the first device can install the target application and perform data recovery. For example, in step S103, the first device sends a second request to device C, so that device C sends the application package of application m to the first device, so that the first device can install the highest version of application m and recover the corresponding data.

[0137] For example, Figure 10(e) is a schematic diagram of an embodiment of the data transmission method of this application, showing the application in the first device being migrated from device A. In this embodiment, applications A1, A2, and A3 in device A are selectively migrated to the first device; that is, the application packages of applications A1, A2, and A3 in device A are transmitted to the first device, enabling the first device to complete program cloning. Figure 10(f) is a schematic diagram of an embodiment of the data transmission method of this application, showing the application in the first device being migrated from device A, device B, and device C. In this embodiment, applications A1, A2, and A3 in device A, applications B1 and B2 in device B, and applications C1 and C2 in device C are selectively migrated to the first device, enabling the first device to complete program cloning.

[0138] In one possible implementation, the first device includes device type information, which further includes compatibility information between the application and the device type, and the version of the application. After receiving the first information sent by the second device, the method further includes:

[0139] S201. Based on the compatibility information and device type information in the first information, determine the application of the second device in the first information, and determine the same application of multiple second devices in the first information based on the version, and determine the fourth information.

[0140] In other words, the fourth information may include a target application of the second device that is compatible with the first device, wherein the target application has the highest version relative to the same application in other second devices, so that the first device can install the highest compatible version of the target application and restore the corresponding data.

[0141] In one possible implementation, the first information is updated by the second device based on changes in the application package.

[0142] Specifically, when an application is installed or uninstalled on the second device, the corresponding application identifier is added or deleted from the first information to achieve information synchronization between the first device and the second device.

[0143] Optionally, when a second device disconnects from the first device, such as due to a network failure or offline status of the second device, all application identifiers and device identifiers of the corresponding second device are deleted from the first information. Conversely, when a second device reconnects to the first device, the application identifier and device identifier of the corresponding second device are added to the first information.

[0144] In other words, if a disconnection is detected between the first device and the second device, the application identifier or device identifier of the second device is deleted. For example, the distributed database of the first device stores the device identifier and application identifier of device A, the device identifier and application identifier of device B, and the device identifier and application identifier of device C. If a disconnection is detected between device A and the first device, the device identifier of device A and all application identifiers of device A are deleted from the distributed database of the first device.
