Description

Data synchronization method, electronic device and system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 6, 2023, with application number 202311162897.3 and application name “Data Synchronization Method, Electronic Device and System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to a data synchronization method, electronic device, and system. Background Art

[0003] With the development of terminal technology, electronic devices can establish connections with various other electronic devices, forming a distributed communication system. In a distributed communication system, electronic devices can synchronize data with other devices to ensure data consistency across multiple electronic devices.

[0004] For example, while a note-taking app is running on a mobile phone, it updates the app's content in response to a user's editing operation. The mobile phone then sends the updated note content to the tablet via a cloud server through end-to-cloud synchronization. This way, when the tablet launches the note-taking app in response to the user's operation, the note content displayed will be the most recent note edited on the phone, providing convenience for the user.

[0005] However, in the above process, it is difficult to ensure the timeliness of data synchronization between different electronic devices through end-cloud synchronization, which affects the user experience.

[0006] Summary of the Invention

[0007] To address the aforementioned technical issues, the present application provides a data synchronization method, electronic device, and system. The technical solution provided by the present application allows the electronic device to synchronize procedural data and persistent data separately based on the data type of the data to be synchronized, thereby ensuring both the timeliness and stability of data synchronization.

[0008] In order to achieve the above technical objectives, this application provides the following technical solutions:

[0009] In a first aspect, a data synchronization method is provided, applied to a first electronic device. The method includes: displaying a first application interface; receiving a first user operation on the first application; obtaining first data and second data of the first application generated by the first operation, wherein the first data is data not stored in a storage module of the first electronic device, and the second data is data stored in the storage module; sending the first data to a second electronic device; and sending the second data to a cloud server.

[0010] In some examples, the data types include, for example, processed data and persistent data. The first electronic device may distinguish between processed data and persistent data based on whether the generated data is saved to a storage module. For example, after the first electronic device saves the generated data to a storage module, the data in the storage module is persistent data; data not saved to the storage module by the first electronic device is processed data. In some examples, a storage module is a storage medium capable of storing data. For example, a storage module is a read-only memory (ROM), such as a hard disk, a mechanical hard disk, a solid-state drive, a magnetic disk, and the like.

[0011] In this way, the first and second electronic devices can flexibly synchronize data between different devices through various data synchronization methods, such as procedural data end-to-end synchronization and persistent data end-to-cloud synchronization, based on the data type. This ensures both the timeliness and stability of data synchronization.

[0012] According to the first aspect, sending the first data to the second electronic device includes: sending the first data to the second electronic device via a short-range communication method, where the short-range communication method includes at least one of a Bluetooth point-to-point connection P2P communication method, a Wireless Fidelity Wi-Fi P2P communication method, and a local area network communication method.

[0013] In this way, after acquiring the process data (ie, the first data), the first electronic device directly sends the process data to the second electronic device. By using the end-to-end synchronization method, the efficiency of data synchronization is improved.

[0014] According to the first aspect, or any implementation of the first aspect above, the method further includes: receiving a second operation of the user on the first application, obtaining fourth data of the first application generated by the second operation, where the fourth data is data saved to the storage module. Under preset conditions, the fourth data is sent to the second electronic device, where the preset conditions include one or more of the following: failure to send the fourth data to the cloud server, the cloud synchronization function is not enabled, the cloud space capacity is insufficient, and the end-to-end synchronization priority is higher than the end-to-cloud synchronization priority.

[0015] In this way, persistent data is synchronized between the first electronic device and the second electronic device on demand through end-to-end synchronization, avoiding data synchronization anomalies caused by failure of end-to-cloud synchronization, which affects user use.

[0016] Furthermore, in some scenarios, end-to-end synchronization can achieve better data synchronization benefits, so the first electronic device can directly choose to synchronize persistent data through end-to-end synchronization. For example, based on factors such as the current network status, the first electronic device determines that end-to-end synchronization is more efficient than end-to-cloud synchronization. The first electronic device can send all data (including processed data and persistent data) to the second electronic device through end-to-end synchronization.

[0017] According to the first aspect, or any implementation of the first aspect above, the method further includes: receiving a third operation performed by a user on the first application, obtaining seventh data of the first application generated by the third operation, wherein the seventh data is data stored in the storage module, and the amount of the seventh data is greater than a preset threshold. Under preset conditions, sending first information about the seventh data to the second electronic device, the first information including the storage address and / or abbreviation information of the seventh data.

[0018] For example, during on-demand end-to-end synchronization of persistent data between a first electronic device and a second electronic device, the first electronic device determines that the amount of newly added image data in the note application is small and can directly synchronize the attachments through end-to-end synchronization. Alternatively, the first electronic device determines that the amount of newly added video data in the note application is large and can synchronize the video's address through end-to-end synchronization. Subsequently, after obtaining the persistent data of the note application from the cloud server, the second electronic device can discard the already synchronized images and save the video with the unsynchronized attachment content.

[0019] In this way, the first electronic device can synchronize persistent data with the second electronic device end-to-end according to the data volume, thereby improving the end-to-end synchronization efficiency of persistent data.

[0020] According to the first aspect, or any implementation of the first aspect above, the method further includes: receiving a data saving operation from a user or detecting that a data saving period is satisfied, saving the first data to a storage module, and sending the first data in the storage module to a cloud server.

[0021] For example, if the first electronic device saves the procedural data to the storage module in response to a user operation, the procedural data becomes persistent data. The first electronic device sends the persistent data to the cloud server according to a preset period or after confirming that the persistent data has been obtained.

[0022] For another example, if the first application is configured with an automatic save function and automatically saves the process data according to a preset period, the first electronic device can send the persistent data to the cloud server after obtaining the latest persistent data saved in the storage module.

[0023] In this way, the first electronic device divides the procedural data and the persistent data according to whether the data is saved, and synchronizes the procedural data and the persistent data in different ways, thereby ensuring the timeliness and stability of data synchronization.

[0024] In a second aspect, a data synchronization method is provided, applied to a second electronic device. The method includes: receiving first data sent by a first electronic device; and downloading, from a cloud server, second data sent by the first electronic device to the cloud server; wherein the first data and the second data are data generated by a first application in the first electronic device, the first data being data not stored in a storage module of the first electronic device, and the second data being data stored in the storage module of the first electronic device.

[0025] According to the second aspect, receiving first data sent by a first electronic device includes: receiving first data sent by the first electronic device via a short-range communication method, where the short-range communication method includes at least one of a Bluetooth point-to-point connection P2P communication method, a Wireless Fidelity Wi-Fi P2P communication method, and a local area network communication method.

[0026] According to the second aspect, or any implementation of the second aspect above, downloading from a cloud server second data sent by a first electronic device to the cloud server includes: obtaining first data information of third data sent by the cloud server, where the third data includes the second data and data in the first data that has been saved to a storage module; and requesting, based on the first data information, from the cloud server to download second data in the third data that has not been end-to-end synchronized with the first electronic device.

[0027] In this way, the consistency of the data in the second electronic device and the data in the first electronic device is ensured and synchronized, and data conflicts between different devices are avoided.

[0028] According to the second aspect, or any implementation of the second aspect above, the method also includes: receiving fourth data sent by the second electronic device under preset conditions, the fourth data being data that the first electronic device has saved to the storage module; the preset conditions include one or more of the following: the first electronic device fails to send the fourth data to the cloud server, the first electronic device does not turn on the cloud synchronization function, the cloud space capacity is insufficient, and the end-to-end synchronization priority is higher than the end-to-cloud synchronization priority.

[0066] The technical solutions in the embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application. Among them, in the description of the embodiments of the present application, the terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to include expressions such as "one or more", unless there is a clear indication to the contrary in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one or more (including two).

[0067] References to "one embodiment" or "some embodiments" etc. described in this specification mean that the specific features, structures or characteristics described in conjunction with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in another way. The term "connected" includes direct and indirect connections, unless otherwise stated. "First" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0068] In the embodiments of this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0069] In some embodiments, multiple electronic devices in a distributed communication system can synchronize data through end-to-end synchronization to ensure consistency of multi-end data.

[0070] For example, as shown in Figure 1, electronic device A updates the content of the note application in response to the user's editing operation during the running of the note application, and saves the updated note content to the storage module. Afterwards, electronic device A sends the note content (i.e., data A) in the storage module to the cloud server through end-cloud synchronization. Then, electronic device B can download the note content from the cloud server. In this way, after electronic device B responds to the user's operation and starts the note application, the note content displayed is the latest note content edited by the user on electronic device A, which is convenient for the user.

[0071] However, in the above process, it is difficult to ensure the timeliness of data synchronization between different electronic devices through end-to-end synchronization, which affects the user experience. For example, when the mobile phone determines that it needs to send the updated note content to the cloud server, the current network quality is poor and the transmission fails. In this process, since the mobile phone fails to upload the updated note content to the cloud server, the tablet also fails to obtain the latest note content. Then, if the user opens the note application on the tablet side at this time, he will not be able to view the latest note application content.

[0072] Furthermore, some electronic devices are not configured or have not enabled the cloud synchronization function, resulting in the inability to synchronize data with other devices through end-to-cloud synchronization. Alternatively, some electronic devices may be configured by the user to only synchronize cloud data when using wireless networks, but not when using carrier data plans, thus affecting the timeliness of data synchronization.

[0073] In other embodiments, multiple electronic devices in a distributed communication system may synchronize data through end-to-end synchronization, thereby ensuring consistency of multi-end data.

[0074] For example, as shown in Figure 2, electronic device A, while running a note-taking application, updates the note content in response to a user's editing operation, generating procedural data for the note-taking application. During this process, electronic device A detects a nearby electronic device B and establishes a communication connection with electronic device B. Electronic device A can then synchronize the procedural data updated by the note-taking application (i.e., data A) to electronic device B in real time. In this way, electronic device B, in response to the user's operation, launches the note-taking application and can display the latest note content edited by the user on electronic device A in real time, making it easier for the user to use it.

[0075] However, in the above process, the stability of the end-to-end connection between devices is poor and easily interrupted. In addition, the data transmission speed is slow, which affects the efficiency of data synchronization between different electronic devices through end-to-end synchronization.

[0076] In addition, electronic devices can only perform end-to-end data synchronization when using wireless networks, but cannot perform end-to-end data synchronization when using operator data traffic, which affects the timeliness of data synchronization.

[0077] In some other embodiments, different electronic devices synchronize cursors through end-to-end data synchronization, while other data are synchronized through end-to-cloud synchronization. However, in this solution, the above technical problems still exist.

[0078] Therefore, an embodiment of the present application provides a data synchronization method. After the electronic device generates the data to be synchronized, it synchronizes the procedural data and the persistent data separately according to the data type of the data to be synchronized, thereby ensuring the timeliness of data synchronization while ensuring the stability of data synchronization.

[0079] Figure 3 is a schematic diagram of a communication system to which the data synchronization method provided in an embodiment of the present application is applied. As shown in Figure 3, the communication system includes a first electronic device 100, a second electronic device 200, and a server 300.

[0080] Optionally, the first electronic device 100 or the second electronic device 200 may be, for example, a mobile phone, a tablet computer, a laptop computer, a smart screen, a wearable device, a vehicle-mounted terminal, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), an artificial intelligence (AI) device or other terminal device, and the operating system installed on the first electronic device 100 or the second electronic device 200 includes but is not limited to This application does not limit the specific type of the first electronic device 100 or the second electronic device 200 or the installed operating system.

[0081] Optionally, the server 300 may be a device or server with computing capabilities such as a cloud server or a network server. The server may be a single server, a server cluster consisting of multiple servers, or a cloud computing service center.

[0082] In some embodiments, the first electronic device 100 is the electronic device that generates the data to be synchronized, and the second electronic device 200 is the electronic device with which data synchronization is to be performed. After generating the data to be synchronized, the first electronic device 100 determines the data type and sends the procedural data to the second electronic device 200 via end-to-end synchronization; and sends the persistent data to the second electronic device 200 via end-to-cloud synchronization.

[0083] Optionally, the first electronic device 100 and the second electronic device 200 in the embodiment of the present application may be implemented by the same or different devices, and the different devices may have the same, similar or somewhat different hardware structures, such as the hardware structure shown in FIG. 4 .

[0084] For example, taking the first electronic device 100 having the hardware structure shown in FIG. 4 as an example, the hardware structure shown in FIG. 4 is described.

[0085] As shown in Figure 4, the first electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc.

[0086] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the first electronic device 100. In other embodiments of the present application, the first electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0087] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). The different processing units may be independent devices or integrated into one or more processors.

[0088] The controller can generate operation control signals according to the instruction operation code and timing signal to complete the control of instruction fetching and execution.

[0089] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

[0090] In some embodiments, the processor 110 may include one or more interfaces.

After being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs the sound signal through the audio device or displays an image or video through the display screen 194.

[0114] The software system of the first electronic device 100 or the second electronic device 200 can adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes the Android system with a layered architecture as an example to illustrate the software structure of the first electronic device 100 or the second electronic device 200.

[0115] FIG5 is a block diagram of the software structure of the first electronic device 100 according to an embodiment of the present application. The second electronic device 200 may have the same, similar or slightly different software structure.

[0116] A layered architecture divides software into several layers, each with distinct roles and responsibilities. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0117] The application layer can include a series of application packages.

[0118] As shown in FIG5 , the application package may include applications such as notes, contacts, memos, sports health, clipboard, gallery, map, camera, video, etc.

[0119] The application framework layer provides an application programming interface (API) and programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0120] As shown in FIG5 , the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

[0121] The window manager is used to manage window programs. The window manager can obtain the display size, determine whether there is a status bar, lock the screen, take screenshots, etc.

[0122] Content providers are used to store and retrieve data and make it accessible to applications. Data can include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0123] The view system includes visual controls, such as those for displaying text and images. The view system is used to build applications. A display interface can consist of one or more views. For example, a display interface containing a text notification icon might include a view for displaying text and a view for displaying images.

[0124] The phone manager is used to provide communication functions of the first electronic device 100, such as management of call status (including answering, hanging up, etc.).

[0125] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0126] The notification manager allows applications to display notification information in the status bar. It can be used to convey informational messages and can disappear automatically after a short stay without user interaction. The notification manager can also be a notification that appears in the top status bar of the system in the form of an icon or scrolling text bar.

[0127] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

[0128] The core library consists of two parts: one is the function that needs to be called by the Java language, and the other is the Android core library.

[0129] The application layer and application framework layer run in a virtual machine. The virtual machine executes Java files in the application layer and application framework layer as binary files. The virtual machine manages object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0130] The system library can include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0131] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0132] The media library supports playback and recording of a variety of common audio and video formats, as well as static image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0133] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0134] A 2D graphics engine is a drawing engine for 2D drawings.

[0135] The kernel layer is the layer between hardware and software. The kernel layer includes at least display driver, camera driver, audio driver, and sensor driver.

[0136] The following describes the workflow of the software and hardware of the first electronic device 100 and the second electronic device 200 in conjunction with the synchronization scenario of note data.

[0137] In the first electronic device 100, when the touch sensor receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, timestamp of the touch operation and other information). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking the example that the touch operation is a touch single-click operation and the control corresponding to the single-click operation is the control of the note application icon, the note application calls the interface of the application framework layer to start the note application. Afterwards, during the process of displaying the note application, the first electronic device 100 detects the user's touch operation in the note application through the touch sensor, determines that the note application generates new data, and needs to synchronize data.

[0138] Afterwards, if the first electronic device 100 detects the second electronic device 200 located nearby and determines to establish a communication connection with the second electronic device 200, the first electronic device 100 can send the newly generated note data to the second electronic device 200. The newly generated note data is the processed data generated in real time by the note application in the first electronic device 100. In this way, data synchronization between the note applications in the first electronic device 100 and the second electronic device 200 is achieved through end-to-end synchronization.

[0139] If the first electronic device 100 does not detect the second electronic device 200 located nearby. Then, the first electronic device 100 can save the newly generated note data to the storage module in response to the user's save operation. Subsequently, the first electronic device 100 uploads the note data saved in the storage module to the cloud server. The note data uploaded to the cloud server is the persistent data of the note application in the first electronic device 100. Correspondingly, the second electronic device 200 can obtain the note data by downloading it from the cloud server. In this way, data synchronization of the note applications in the first electronic device 100 and the second electronic device 200 is achieved through end-to-cloud synchronization.

[0140] The following describes in detail the data synchronization method provided in the embodiment of the present application, taking the first electronic device 100 as the electronic device that generates the data to be synchronized and the second electronic device 200 as the electronic device to perform data synchronization as an example.

[0141] In some embodiments, an electronic device may generate data of different data types while running an application. In some examples, the data types include procedural data and persistent data. The electronic device may distinguish between procedural data and persistent data based on whether the generated data is saved to a storage module. For example, after the electronic device saves the generated data to a storage module, the data in the storage module is persistent data; data not saved to the storage module by the electronic device is procedural data.

[0142] In some examples, the storage module is a storage medium capable of storing data, such as a read-only memory (ROM), such as a hard disk, a mechanical hard disk, a solid-state drive, a magnetic disk, and the like.

[0143] For example, procedural data includes text content, attachment information, cursor position, and other data generated by the application in real time. Persistent data includes attachments stored in storage modules such as images, videos, documents, and text content.

[0144] In some embodiments, after generating data, the electronic device synchronizes data of different data types separately based on the data type. In some examples, the electronic device synchronizes procedural data with other electronic devices through end-to-end synchronization, thereby ensuring the timeliness of procedural data synchronization. The electronic device synchronizes persistent data with other electronic devices through end-to-cloud synchronization, thereby ensuring the stability of persistent data synchronization.

[0145] Exemplarily, as shown in FIG6 , the first electronic device generates new note content in response to user operations while running a note application. During this process, the first electronic device detects a second electronic device located nearby, and the first electronic device can establish a communication connection with the second electronic device (or a communication connection has already been established between the first electronic device and the second electronic device). Afterwards, while updating the note content, the first electronic device can send the updated note content to the second electronic device through end-to-end synchronization. That is, the first electronic device synchronizes the procedural data to the second electronic device through end-to-end synchronization. In this way, if the first electronic device is running a note application, the second electronic device is also running a note application. Then, through end-to-end data synchronization, the second electronic device can synchronously display the note content edited by the user in the note application in the first electronic device. Alternatively, after the second electronic device starts the note application in response to user operations, it can display the note content synchronized by the first electronic device through end-to-end synchronization, so that the user can continue to edit the note content through the second electronic device.

[0146] As another example, as shown in Figure 7, in response to a user's save operation, the first electronic device saves the updated note content to the storage module. The storage module then stores attachments from the note application, which may include text, images, videos, and the like entered by the user in the note application. The first electronic device can then upload the attachments from the note application to the cloud server, completing end-to-end synchronization of the first electronic device's persistent data. Subsequently, the second electronic device can download the persistent data uploaded by the first electronic device from the cloud server as needed and save it to the storage module, completing end-to-end synchronization of the second electronic device's persistent data. In other words, data synchronization between the first and second electronic devices is achieved through end-to-end synchronization. For example, in response to a user's instruction to launch the note application, the second electronic device sends a data synchronization request to the cloud server to synchronize the note content. After end-to-end synchronization, the second electronic device can display the note content edited by the user on the first electronic device, allowing the user to continue editing the note content on the second electronic device. In this way, data synchronization can be achieved through end-to-end synchronization regardless of whether the second electronic device is near the first electronic device.

[0147] In some embodiments, after generating persistent data, the electronic device may also synchronize data with other electronic devices through end-to-end synchronization as needed.

[0148] For example, as shown in FIG8 , while running a note-taking application, the first electronic device, in response to a user operation, stores the generated procedural data of the note-taking application in a storage module, thereby generating persistent data of the note-taking application. If any one or more of the following situations occur, the first electronic device will synchronize persistent data with other devices as needed through end-to-end synchronization. For example, the first electronic device may not be configured with a cloud synchronization function, the cloud synchronization function is not enabled, the current network quality is poor and the persistent data cannot be uploaded to the cloud server, the cloud space capacity is insufficient, the wireless communication network function is not enabled or the wireless communication network (such as a Wi-Fi network) is not connected, or the end-to-end synchronization priority is determined to be higher than the end-to-cloud synchronization priority. The priority order between end-to-end synchronization and end-to-cloud synchronization can be a preconfigured priority order in the first electronic device or a user-defined priority order. Different user accounts correspond to different cloud spaces. After the first electronic device logs in to a user account, it can access the corresponding cloud space for data backup, etc. The cloud space capacity is limited, so if the cloud space capacity is insufficient, the first electronic device cannot send persistent data to the cloud server.

[0149] It should be understood that in some other demand scenarios, the first electronic device may also send persistent data to the second electronic device through end-to-end synchronization as needed, and this embodiment of the application will not illustrate this one by one. For example, if the first electronic device determines that the opposite device (such as the second electronic device) cannot download data from the cloud server, it may also send persistent data to the opposite device through end-to-end synchronization.

[0150] In various cases of the above examples, the first electronic device detects a second electronic device located nearby, and the first electronic device can establish a communication connection with the second electronic device (or a communication connection has already been established between the first electronic device and the second electronic device). Afterwards, the first electronic device can send the persistent data of the note application stored in the storage module to the second electronic device through the communication connection between the first electronic device and the second electronic device. This enables the synchronization of persistent data between the first electronic device and the second electronic device through end-to-end synchronization on demand, avoiding data synchronization anomalies caused by the inability to perform end-to-cloud synchronization, which affects user use.

[0151] In some embodiments, the manner in which the procedural data is stored in the storage module includes storing it in the form of a file and storing it in the form of a database. Storing it in the form of a file represents storing the data content of the procedural data. For example, in response to a user's save operation in a note application, the electronic device stores the video content newly added by the user in the note application in the form of a file in the storage module. Storing it in the form of a database represents storing a uniform resource locator (URL) corresponding to the file in the storage module, and the URL indicates a specific file storage address. For example, after the electronic device saves the video content in the form of a file in the storage module in response to a user's save operation, it determines the URL of the storage address and stores the URL in the form of a database. Optionally, a file directory corresponding to the note application is stored in the database, and the file directory includes one or more URLs for indexing one or more files of the note application stored in the storage module.

[0152] In some examples, the first electronic device establishes a point-to-point connection (P2P) with the second electronic device through Bluetooth, Wi-Fi, etc., and realizes end-to-end data synchronization through the P2P connection. Generally, the data transmission speed of the P2P connection is slow. Therefore, in order to ensure the efficiency of data synchronization, when it is necessary to synchronize persistent data through the end, you can choose to synchronize the file corresponding to the persistent data (such as an attachment stored in the form of a file), or choose to synchronize the information of the persistent data, such as the information including the database content corresponding to the persistent data (such as the URL stored in the database) or thumbnail information (such as thumbnails, video covers, etc.). In this way, when the amount of persistent data is large, the first electronic device and the second electronic device can also achieve data synchronization by synchronizing the information of the persistent data. Subsequently, the second electronic device can also read the persistent data across devices on demand based on the information of the persistent data.

[0153] Exemplarily, as shown in FIG9 , after the electronic device stores the procedural data in the storage module, the stored content includes attachments stored in the form of files and attachment URLs stored in the form of a database.

[0154] In one scenario, while running a note-taking application, the first electronic device detects that the user clicks on the save control and saves the text content entered by the user to a storage module. The first electronic device determines that it is currently unable to upload the text content to the cloud server, and determines that a P2P connection has been established with a second electronic device located nearby. Then, the first electronic device can synchronize the text content to the second electronic device through end-to-end synchronization. The second electronic device saves the text content to the storage module to complete the data synchronization of the note-taking application.

[0155] In another scenario, the first electronic device detects the user clicking the save control while running the note application, and saves the video file input by the user to the storage module. The first electronic device determines that the video file cannot be uploaded to the cloud server at present, and determines that a P2P connection has been established with a second electronic device located nearby. Since the data volume of the video file is large, the first electronic device can synchronize the cover information and URL of the video file to the second electronic device through end-to-end synchronization. The second electronic device saves the cover information and URL of the video file to the storage module to complete the data synchronization of the note application. Subsequently, the second electronic device starts the note application in response to the user operation, and can display the cover of the video file. If it is detected that the user clicks on the cover of the video file, the second electronic device can then request the first electronic device to obtain the video stream of the video file by reading the file across devices based on the URL of the video file. This ensures the efficiency of data synchronization while also ensuring the effectiveness of data synchronization.

[0156] Therefore, as shown in Figure 10, the first electronic device and the second electronic device can flexibly realize data synchronization between different devices according to the data type and the current data synchronization scenario through various data synchronization methods such as procedural data end-to-end synchronization, persistent data end-to-cloud synchronization, and persistent data on-demand end-to-end synchronization.

[0157] In some embodiments, data synchronization is performed between different electronic devices in a variety of ways. While ensuring data consistency across multiple terminals, it is also necessary to avoid duplicate data synchronization.

[0158] In some examples, the electronic device determines the consistency and repeatability of data synchronization by comparing data.

[0159] For example, after obtaining synchronized data through end-to-end synchronization or end-to-cloud synchronization, the second electronic device compares the synchronized data with local data to determine whether the same data is already stored locally. If the same data is already stored locally, the second electronic device may discard the synchronized data. If the same data is not stored locally, the second electronic device may save the synchronized data.

[0160] Exemplarily, as shown in FIG10 , during the operation of the note application, the first electronic device generates procedural data of the note application in response to user operations, and synchronizes the procedural data to a second electronic device located nearby through end-to-end synchronization. The second electronic device obtains and saves the procedural data. Subsequently, the first electronic device saves the procedural data of the note application to the storage module in response to the user's save operation, and obtains the persistent data of the note application. Afterwards, the first electronic device uploads the persistent data of the note application to the cloud server. Correspondingly, the second electronic device requests the cloud server to download the persistent data of the note application. Among them, the persistent data of the note application may include the procedural data of the note application previously obtained by the first electronic device and the second electronic device through end-to-end synchronization. Therefore, the second electronic device can determine whether it needs to retain part or all of the persistent data obtained from the cloud server by data comparison.

[0161] For example, during the end-to-end synchronization process, the second electronic device obtains 3 pictures input by the user into the note application, and obtains the editing time of the 3 pictures. Subsequently, the persistent data of the note application downloaded by the second electronic device from the cloud server includes the 5 pictures input by the user and the editing time of these 5 pictures. Based on the pictures and editing time, the second electronic device can determine that after the end-to-end synchronization, the first electronic device inserted 2 pictures into the note application based on the user's operation. Therefore, the second electronic device can retain the 2 newly added pictures and discard the 3 pictures downloaded repeatedly from the cloud server. Alternatively, the second electronic device determines that after the end-to-end synchronization, the user edited the 3 pictures that have been synchronized based on the pictures and editing time. Then, the second electronic device can discard the 3 pictures synchronized by the end-to-end synchronization and retain all 5 pictures synchronized from the cloud server.

[0162] In this way, the consistency of the data in the second electronic device and the data in the first electronic device is ensured and synchronized, and data conflicts between different devices are avoided.

[0163] As another example, as shown in FIG10 , the first electronic device inserts pictures and videos into the note application in response to the user's editing operation while running the note application. After the first electronic device detects the user's save operation in the note application, it saves the persistent data of the note application in the storage module. Afterwards, the first electronic device determines that the cloud synchronization function is not currently turned on, and detects a second electronic device located nearby. It can synchronize the persistent data of the note application to the second electronic device through end-to-end synchronization as needed. Subsequently, the first electronic device detects that the user has turned on the cloud synchronization function, and can upload the persistent data of the note application that has not been uploaded to the cloud server to the cloud server.

[0164] For example, after the second electronic device downloads the persistent data of the note application from the cloud server, if it determines that the persistent data has been synchronized with the first electronic device through end-to-end synchronization, the second electronic device can avoid synchronizing the duplicate data again.

[0165] For example, during on-demand end-to-end synchronization of persistent data between a first electronic device and a second electronic device, the first electronic device determines that the amount of newly added image data in the note application is small and can directly synchronize the attachments through end-to-end synchronization. Alternatively, the first electronic device determines that the amount of newly added video data in the note application is large and can synchronize the video URL through end-to-end synchronization. Subsequently, after obtaining the persistent data of the note application from the cloud server, the second electronic device can discard the already synchronized images and save the video attachments without syncing them.

[0166] In this way, the second electronic device pulls data from the cloud server as needed according to the actual data synchronization situation.

[0167] In other examples, the electronic device determines the consistency and repeatability of data synchronization by comparing data information.

[0168] For example, the second electronic device can compare the data edit time to determine whether the edit time of the data in the cloud server is later than the edit time of the local application data. This allows the second electronic device to download only the latest data to be synchronized, without having to repeatedly download historical data, effectively reducing data download power consumption and data synchronization time. In other words, the second electronic device first determines the edit time of the data to be synchronized and downloads the attachment from the cloud server as needed. If the attachment has not changed, it does not need to be downloaded again.

[0169] For example, as shown in FIG10 , while running a note-taking application, a first electronic device generates procedural data for the note-taking application in response to a user's editing operation, and synchronizes the procedural data to a nearby second electronic device through end-to-end synchronization. The second electronic device obtains and saves the procedural data. Subsequently, the first electronic device saves the procedural data of the note-taking application to a storage module in response to the user's save operation, obtaining the persistent data of the note-taking application. The first electronic device then uploads the persistent data of the note-taking application to a cloud server.

[0170] Afterwards, the second electronic device responds to the user's operation of starting the note application by sending a data synchronization request to the cloud server, and the data synchronization request carries the note application identifier. Accordingly, the cloud server receives the data synchronization request and determines the data of the note application that the second electronic device requests to synchronize based on the note application identifier carried in the data synchronization request. The cloud server can determine the note application data uploaded by the first electronic device and obtained between the second electronic device's last data synchronization and this data synchronization as data to be synchronized, and send information about the data to be synchronized to the second electronic device; or, the cloud server directly determines all the note application data as data to be synchronized, and sends information about the data to be synchronized to the second electronic device.

[0171] Accordingly, after receiving the information about the data to be synchronized from the cloud server, the second electronic device compares the information about the data to be synchronized with the local data information of the note-taking application, determines the data that actually needs to be synchronized, and then sends a data synchronization request to the cloud server again, including the information about the data that actually needs to be synchronized. Accordingly, after receiving the data synchronization request, the cloud server sends the corresponding data to be synchronized to the second electronic device based on the data information contained in the request.

[0172] In this way, the second electronic device can synchronize data with the first electronic device, avoid downloading duplicate attachment data, and improve the efficiency of end-cloud data synchronization.

[0173] As another example, when the first electronic device is running a note application, it updates the note application content in response to user operations and sends the updated note content to the second electronic device through end-to-end synchronization. If the second electronic device is also running a note application, the first electronic device and the second electronic device can synchronously display the note application content edited by the user; or, if the second electronic device is not running a note application, it can also save and obtain the note content. Subsequently, the first electronic device uploads the updated content and update time of the note application to the cloud server in response to the user's operation of saving the note application. When the second electronic device requests the cloud server to synchronize the note application data, it can be determined that there is no need to synchronize the note content with the cloud server based on the fact that the last update time of the note content fed back by the cloud server (such as the time when the note content is uploaded to the cloud server) is earlier than the synchronization time of the locally stored note content.

[0174] In this way, the second electronic device determines whether data synchronization is required by comparing the final update time of the data to be synchronized, thereby effectively improving the data synchronization efficiency.

[0175] Figure 11 is a flow chart of a data synchronization method provided in an embodiment of the present application. It should be noted that the method is not limited to the specific sequence shown in Figure 11 and below. It should be understood that in other embodiments, the order of some steps in the method can be interchanged according to actual needs, or some steps can be omitted or deleted. The method includes the following steps:

[0176] S1101: A first electronic device displays an interface of a first application.

[0177] In some embodiments, the first electronic device runs a first application in the foreground and displays the interface of the first application. During the process of displaying the interface of the first application, the first electronic device may receive a user operation, and the user operation may generate data for the first application.

[0178] S1102: The first electronic device receives a first operation of a user on a first application, and obtains first data and second data of the first application generated by the first operation, wherein the first data is data not stored in a storage module of the first electronic device, and the second data is data stored in the storage module of the first electronic device.

[0179] The first data is procedural data that has not been saved to the storage model, and the second data is persistent data that has been saved to the storage module. Optionally, the storage module is a storage medium capable of storing data. The storage module is, for example, a ROM, such as a hard disk, a mechanical hard disk, a solid-state drive, a magnetic disk, etc.

[0180] In some embodiments, a first application may detect a first user operation and generate data for the first application. For example, if the first operation is an edit operation, the first application may generate procedural data based on the user's edit. For another example, if the first operation is a save operation, the first application may save second data to a storage module based on the user's operation, and the second data may be persistent data.

[0181] In some examples, the first application may generate procedural data and / or persistent data during operation.

[0182] S1103: The first electronic device sends first data to the second electronic device.

[0183] S1104. The first electronic device sends second data to the cloud server.

[0184] In some embodiments, after acquiring the first data of the first application generated by the first operation, the first electronic device directly sends the first data to a second electronic device. The second electronic device is an electronic device near the first electronic device, and a short-range communication connection is established between the first electronic device and the second electronic device.

[0185] In some examples, a first electronic device transmits first data to a second electronic device via a short-range communication method. Correspondingly, the second electronic device receives the first data transmitted by the first electronic device via the short-range communication method. The short-range communication method includes at least one of a Bluetooth P2P communication method, a Wi-Fi P2P communication method, and a local area network communication method.

[0186] In some embodiments, after obtaining the second data of the first application generated by the first operation, the first electronic device uploads the second data to the cloud server so that other electronic devices can download the second data.

[0187] It should be understood that the embodiment of the present application does not limit the execution order of S1103 and S1104.

[0188] S1105. The second electronic device downloads the second data to the cloud server.

[0189] In some embodiments, the second electronic device obtains first data information of third data sent by the cloud server, where the third data includes the second data and data in the first data that has been saved to the storage module. Based on the first data information, the second electronic device requests the cloud server to download second data in the third data that has not been synchronized end-to-end with the first electronic device.

[0190] In this way, the second electronic device can request data synchronization from the cloud server as needed, and the second electronic device can pull data from the cloud server that has not been synchronized with other electronic devices, thereby reducing the amount of data downloaded and allowing the second electronic device to obtain the latest application data.

[0191] In some embodiments, the first electronic device receives a data saving operation from a user or detects that a data saving period is satisfied, saves the first data to the storage module, and sends the first data in the storage module to the cloud server.

[0192] For example, if the first electronic device saves the procedural data to the storage module in response to a user operation, the procedural data becomes persistent data. The first electronic device sends the persistent data to the cloud server according to a preset period or after confirming that the persistent data has been obtained.

[0193] For another example, if the first application is configured with an automatic save function and automatically saves the process data according to a preset period, the first electronic device can send the persistent data to the cloud server after obtaining the latest persistent data saved in the storage module.

[0194] In this way, the first electronic device divides the procedural data and the persistent data according to whether the data is saved, and synchronizes the procedural data and the persistent data in different ways, thereby ensuring the timeliness and stability of data synchronization.

[0195] Exemplarily, as shown in FIG10 , during the process of running a first application (such as a note application), the first electronic device generates procedural data of the note application in response to a user operation, and synchronizes the procedural data to a second electronic device located nearby through end-to-end synchronization. The second electronic device obtains and saves the procedural data. Subsequently, the first electronic device saves the procedural data of the note application to a storage module in response to the user's save operation, and obtains the persistent data of the note application. Afterwards, the first electronic device uploads the persistent data of the note application to the cloud server. Correspondingly, the second electronic device requests the cloud server to download the persistent data of the note application. Among them, the persistent data of the note application may include the procedural data of the note application previously obtained by the first electronic device and the second electronic device through end-to-end synchronization. Therefore, the second electronic device can determine whether it needs to retain some or all of the persistent data obtained from the cloud server by data comparison.

[0196] In this way, the consistency of the data in the second electronic device and the data in the first electronic device is ensured and synchronized, and data conflicts between different devices are avoided.

[0197] In some embodiments, the first electronic device receives a second operation of the user on the first application, obtains fourth data of the first application generated by the second operation, and the fourth data is data saved in the storage module. Under preset conditions, the first electronic device sends the fourth data to the second electronic device. Correspondingly, the second electronic device receives the fourth data sent by the second electronic device under preset conditions. Among them, the preset conditions include one or more of the following: failure to send the fourth data to the cloud server, the cloud synchronization function is not turned on, the cloud space capacity is insufficient, and the end-to-end synchronization priority is higher than the end-to-cloud synchronization priority.

[0198] For example, as shown in FIG10 , the first electronic device inserts pictures and videos into the note application in response to the user's editing operation while running the note application. After the first electronic device detects the user's save operation in the note application, it saves the persistent data of the note application in the storage module. Afterwards, the first electronic device determines that the cloud synchronization function is not currently turned on, and detects a second electronic device located nearby. It can synchronize the persistent data of the note application to the second electronic device through end-to-end synchronization as needed. Subsequently, the first electronic device detects that the user has turned on the cloud synchronization function, and can upload the persistent data of the note application that has not been uploaded to the cloud server to the cloud server.

[0199] In this way, the first electronic device and the second electronic device can flexibly realize data synchronization between different devices according to the data type and the current data synchronization scenario through various data synchronization methods such as procedural data end-to-end synchronization, persistent data end-to-cloud synchronization, and persistent data on-demand end-to-end synchronization.

[0200] In some embodiments, a second electronic device receives second data information of fifth data sent by a cloud server, where the fifth data is data of a first application sent by the first electronic device to the cloud server. Based on the second data information, the second electronic device requests the cloud server to download sixth data of the fifth data that has not been end-to-end synchronized with the first electronic device, where the sixth data does not include the fourth data.

[0201] In this way, the second electronic device can pull data from the cloud server as needed according to the actual data synchronization situation, without having to repeatedly download the data that has been synchronized.

[0202] In some embodiments, a first electronic device receives a third operation performed by a user on a first application and obtains seventh data of the first application generated by the third operation, where the seventh data is data that has been saved to a storage module, and the amount of the seventh data is greater than a preset threshold. Under preset conditions, the first electronic device sends first information of the seventh data to a second electronic device. The first information includes the storage address and / or abbreviation information of the seventh data. Correspondingly, the second electronic device receives the first information of the seventh data sent by the first electronic device under the preset conditions.

[0203] For example, during on-demand end-to-end synchronization of persistent data between a first electronic device and a second electronic device, the first electronic device may determine that the amount of newly added image data in a note-taking application is small and may directly synchronize the attachments through end-to-end synchronization. Alternatively, the first electronic device may determine that the amount of newly added video data in the note-taking application is large and may synchronize the video URL through end-to-end synchronization. Subsequently, after obtaining the persistent data of the note-taking application from the cloud server, the second electronic device may discard the already synchronized images and save the video attachments without synchronization.

[0204] In this way, the first electronic device can synchronize persistent data with the second electronic device end-to-end according to the data volume, thereby improving the end-to-end synchronization efficiency of persistent data.
