Description

Technical Field

[0001] This invention relates to the field of resource updating technology, and more specifically, to a method, apparatus, device, and medium for updating emoji resources. Background Technology

[0002] Terminal devices such as children's smartwatches, story machines, and smart toys typically have chat functions. To enhance the fun of chatting, these devices often include the ability to send emoticons to express emotions (happiness, sadness, missing you, etc.), compensating for the limitations of text-based expression.

[0003] Existing terminal devices generally suffer from limited storage space and low CPU computing power. Updating emoji resources requires downloading the entire ZIP package and then using atomic overwriting to achieve rapid upgrades. While some optimization attempts exist, they all face significant problems: First, some solutions attempt to have the device remember old emoji fragment information using differential / patch methods to index old file blocks, but this is extremely difficult to implement due to insufficient ROM / RAM memory in MCU-level devices. Second, if a power outage occurs during the decompression process after a full ZIP download, the working area is prone to "partial write" corruption, resulting in unfinished emoji files that the device cannot recover from. Third, some solutions use a "decompression + single-file comparison" method before overwriting, requiring decompression first and then checking each file individually for replacement, doubling the time required and severely impacting user experience. Fourth, there is a lack of a unified version verification and rollback strategy, which can lead to resource loss or version drift after a failed upgrade, potentially resulting in lost emojis or version inconsistencies. Summary of the Invention

[0004] To quickly update emoji resources on small devices, in a first aspect, embodiments of the present invention provide an emoji resource updating method, applied to a terminal device, the method comprising:

[0005] Send the version number of the emoji resources in the first storage area to the server. The first storage area is the working area.

[0006] Receive the latest version identification information sent by the server;

[0007] The comparison results are obtained by comparing the version number of the emoji resources in the workspace with the version number in the latest version identifier information;

[0008] In response to the comparison result indicating a version difference, the latest emoji resource sent by the server is downloaded to the cache area;

[0009] The latest emoji resources in the cache are decompressed to the second storage area, which is a temporary decompression area.

[0010] Set the first storage area as the backup area and the second storage area as the working area.

[0013] Download the latest emoji resources sent by the server to the cache area, and record the file range of the latest downloaded emoji resources in real time;

[0014] If a power outage occurs during the download process, upon restarting, the system checks if the cache contains any incompletely downloaded latest emoji resources. If so, it sends a resume request to the server, the resume request including data representing the file range of the latest emoji resources being downloaded. The system then downloads the incompletely downloaded latest emoji resources sent by the server to the cache.

[0018] If not, delete the latest emoji resource.

[0019] As one possible implementation, after setting the first storage area as a backup area and the second storage area as a working area, the method further includes:

[0020] Verify the integrity of the second storage area and obtain the verification result;

[0023] Secondly, embodiments of the present invention provide a method for updating emoji resources, applied to a server, the method comprising:

[0024] The version number of the emoji resource sent by the receiving terminal device;

[0025] Determine whether the version number of the emoji resource sent by the terminal device is the same as the version number in the latest version identifier information;

[0026] If so, send the latest version identification information to the terminal device;

[0027] In response to receiving a download request from the terminal device, the latest emoji resources are sent to the terminal device.

[0028] As one possible implementation, the method further includes:

[0029] In response to receiving a resume request sent by the terminal device, the resume request includes data representing the file range of the latest emoji resources being downloaded;

[0030] Send the latest emoji pack resources that have not yet been downloaded to the terminal device.

[0036] The terminal resource decompression module is used to decompress the latest emoji resources in the cache to the second storage area, where the second storage area is a temporary decompression area.

[0037] The terminal resource switching module is used to set the first storage area as a backup area and the second storage area as a working area.

[0038] Fourthly, embodiments of the present invention provide an emoji resource updating device, the device comprising:

[0039] The server-side version receiving module is used to receive the version number of the emoji resources sent by the terminal device;

[0040] The server-side comparison module is used to determine whether the version number of the emoji resource sent by the terminal device is the same as the version number in the latest version identifier information;

[0041] The server version sending module is used to send the latest version identification information to the terminal device if the condition is met.

[0042] The server-side resource sending module is used to send the latest emoji resources to the terminal device in response to receiving a download request from the terminal device.

[0043] Fifthly, embodiments of the present invention provide an electronic device, comprising:

[0044] One or more processors;

[0045] Storage device, on which one or more programs are stored,

[0046] When the one or more programs are executed by the one or more processors, the one or more processors cause the one or more processors to implement the method as described in the first aspect and / or the second aspect.

[0047] In a sixth aspect, embodiments of the present invention provide a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by one or more processors, implements the method as described in the first aspect and / or the second aspect.

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Figure 1 An exemplary architecture 100 is shown, illustrating embodiments of the emoji resource update method, apparatus, electronic device, and storage medium to which the present invention can be applied.

[0060] like Figure 1 As shown, architecture 100 may include terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links, or fiber optic cables, etc.

[0061] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 101, 102, and 103, such as communication applications, voice recognition applications, short video social applications, audio and video conferencing applications, live video streaming applications, document editing applications, input method applications, web browser applications, shopping applications, search applications, instant messaging tools, email clients, social platform software, etc.

[0062] Terminal devices 101, 102, and 103 can be either hardware or software. When terminal devices 101, 102, and 103 are hardware, they can be various electronic devices with displays, including but not limited to children's watches, story machines, smart toys, smartphones, smart home appliances, wearable devices, and desktop computers. When terminal devices 101, 102, and 103 are software, they can be installed in the terminal devices listed above. They can be implemented as multiple software programs or software modules (e.g., to provide communication services) or as a single software program or software module. No specific limitations are imposed here.

[0063] Server 105 can be either hardware or software. When server 105 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When server 105 is software, it can be implemented as multiple software programs or software modules (e.g., used to provide distributed services), or as a single software program or software module. No specific limitations are made here.

[0064] The emoji resource update method provided by this invention can be jointly executed by terminal devices 101, 102, and 103 and server 105. For example, the step of "sending the version number of the emoji resource in the first storage area to the server" can be executed by terminal devices 101, 102, and 103, and the step of "determining whether the version number of the emoji resource sent by the terminal device is the same as the version number in the latest version identifier information" can be executed by server 105. This invention does not limit this. Correspondingly, the emoji resource update device can also be respectively set in terminal devices 101, 102, and 103 and server 105.

[0065] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0066] Continue to refer to Figure 2 The flowchart 200 illustrates an embodiment of the emoji resource update method for terminal devices provided by the present invention, including the following steps:

[0067] Step S201: Send the version number of the emoji resources in the first storage area to the server.

[0068] In this embodiment, the Lightweight Update Engine (LUE) built into the terminal device divides the storage area into four parts: a first storage area, a second storage area, a third storage area, and a cache area. At step S201, the first storage area is the working area. The working area, which is the dedicated folder of the "current working area" in the terminal device, is the core directory for storing and displaying emoticon resources to the user. All emoticon files that are visible and usable by the user are stored here.

[0069] Emoji resources are generally ZIP packages. The version number is a unique identifier for the version of the emoji resource. It is the core basis for determining whether the local resources on the terminal need to be updated. It is consistent with the version number in the version identification information maintained by the server (e.g., ZIP-meta, which may include version number, total size, CRC32 checksum, digital signature, etc.).

[0070] The terminal device actively reads the version number of the emoji resources in the workspace through its built-in Lightweight Update Engine (LUE), and then sends the version number to the server through the communication module. This completes the initial interaction of the terminal reporting the local version, preparing for subsequent version comparison. In other words, it is the operation of the terminal reporting the local ZIP version number.

[0071] Step S202: Receive the latest version identification information sent by the server.

[0072] The latest version identification information, which can be equivalent to ZIP-meta, contains key information such as the version number, total size, CRC32 checksum, and digital signature of the latest emoji resource. It is like an "identity manual" for the latest emoji resource, used by the terminal to determine whether an update is needed and to verify the legality of the resource.

[0073] After receiving the version number sent by the terminal, the server will determine whether the terminal device needs to be updated. If so, it will return the latest version identifier information. The terminal receives this information through the communication module to obtain the core basis for judging whether local resources are outdated.

[0074] Step S203: Compare the version number of the emoji resources in the workspace with the version number in the latest version identifier information to obtain the comparison result.

[0075] The terminal's Lightweight Update Engine (LUE) compares the local version number read from the workspace with the version number in the latest version identifier information. If they match, the local resource is already up-to-date and no further update is needed; if they differ, the subsequent download process is triggered.

[0076] Step S204: In response to the comparison result indicating a version difference, download the latest emoji resources sent by the server to the cache area.

[0077] The cache area, also known as the "download cache area" among the four parts on the terminal side, is a dedicated area for storing ZIP format emoji resources that have just been downloaded or are not yet downloaded. Ideally, it should have the characteristic of not losing data when power is off to avoid data corruption during the download process.

[0078] The latest emoji resource is the only latest Full-ZIP package maintained by the server, containing N emoji resources and a central directory.

[0079] When the version comparison result is "different", the terminal starts the download process, obtains the latest ZIP format emoticon package resources from the server via the HTTP protocol, and stores them in the cache area instead of writing them directly to the working area, ensuring that the download process does not affect the emoticon resources currently in use.

[0080] Specifically, step S204 includes steps S2041 to S2043:

[0081] Step S2041: Send a download request for the latest emoji resources to the server.

[0082] After confirming that an update is needed, the terminal proactively sends a request instruction to the server, explicitly informing the server that "the latest emoji resources are needed". This request will carry basic information such as the terminal's identity and the required resource version, triggering the server's resource sending process, which corresponds to the pre-operation of "the terminal initiates a download request" in the document.

[0083] Step S2042: Download the latest emoji resources sent by the server to the cache area, and record the file range of the latest emoji resources downloaded in real time.

[0084] The file range refers to the byte range (e.g., "0-10240 bytes") corresponding to the downloaded ZIP package data segments. It is the key data for implementing breakpoint resume and is used to mark the download progress.

[0085] The terminal receives ZIP packet data sent by the server, writes it to the buffer, and simultaneously records the file range of each segment of downloaded data in real time, forming a download progress log. This recording method provides a basis for resuming downloads in case of possible interruptions, preventing downloaded data from becoming invalid due to network interruptions or power outages.

[0086] Step S2043: If a power outage occurs during the download process, after restarting, check if there are any unfinished latest emoji resources in the cache; if so, send a resume request to the server, the resume request including data representing the file range of the latest emoji resources being downloaded; download the unfinished latest emoji resources sent by the server to the cache.

[0087] A resume request is a request sent by the terminal to the server after restarting to "continue completing the download of undownloaded resources". The core of it is to carry the range of downloaded files and inform the server that "there is no need to resend the downloaded part".

[0088] If the device experiences an unexpected power outage during the download process, the Lightweight Update Engine (LUE) on the terminal will prioritize checking the cache after restarting. If there are any incomplete ZIP packages, it will read the previously recorded file range, generate and send a resume request to the server. The server, based on the file range in the request, will only send the undownloaded portion of the data. Upon receiving this, the terminal will continue writing the data to the cache to complete the remaining download. This operation fully implements the "resume interrupted download" function, avoiding repeated downloads and saving bandwidth and time.

[0089] As one possible implementation, after step S204, the method further includes: calculating the CRC32 checksum of the latest emoji resource; comparing whether the calculated CRC32 checksum is consistent with the CRC32 checksum in the latest version identification information; if not, deleting the latest emoji resource.

[0090] The CRC32 checksum is a 32-bit value generated by a cyclic redundancy check algorithm. It is used to verify file integrity and is the core criterion for determining whether a ZIP package is corrupted. After downloading, the terminal calculates the CRC32 checksum of the ZIP package in the cache and compares it with the CRC32 checksum in the latest version identifier information (ZIP-meta). If the two do not match, it means that the ZIP package was corrupted during the download process, and the terminal will immediately delete the cached package and report the failure to avoid using corrupted resources; if they match, the subsequent decompression process will proceed.

[0091] Step S205: Decompress the latest emoji resources in the cache area to the second storage area.

[0092] The second storage area at this time is a temporary decompression area, which is a separate area specifically used for decompressing ZIP packages and is completely isolated from the working area.

[0093] The terminal's Lightweight Update Engine (LUE) decompresses verified ZIP packages in the cache to a second storage area (temporary decompression area). Since this directory is independent of the current working area, even if errors occur during decompression (such as file corruption or power failure), it will not contaminate the emoji resources currently in use or their backups, ensuring that the user's current experience is not affected.

[0094] Step S206: Set the first storage area as a backup area and the second storage area as a working area.

[0095] The backup area is used to store the last intact emoji resources, serving as a "recovery guarantee" in case of update failure.

[0096] Optionally, the terminal can rename the directory using a POSIX rename (atomic operation) to set the storage area properties. First, the original working area (first storage area) is renamed to the backup area, completing an immediate backup of the old resources; then, the decompressed second storage area (temporary decompressed area) is renamed to the working area, allowing the new emoji resources to take effect immediately. The entire process is completed in milliseconds, imperceptibly to the user, ensuring the security and efficiency of the switching process.

[0097] As one possible implementation, after step S206, the method further includes:

[0098] Step S207: Verify the integrity of the second storage area and obtain the verification result.

[0099] After the terminal starts up, the Lightweight Update Engine (LUE) performs an integrity check on the second storage area that has been switched to the working area. The check can be performed using sampling CRC or digital signature verification to determine whether the new resources are damaged or missing, and then generate a check result.

[0100] Step S208: In response to the verification result being passed, delete the files in the third storage area and set the third storage area as a temporary decompression area.

[0101] If the verification result is "passed", it means that the new emoji resources are intact and usable. At this time, there is no need to keep the original backup area. The terminal will delete the files in this directory and release storage space, which corresponds to the operation "verification passed → delete / backup / release space" in the document.

[0102] Step S209: In response to the verification result being unsuccessful, the second storage area is set as a temporary decompression area, the first storage area is set as a working area, and the process of sending the version number of the emoji resources in the first storage area to the server is returned.

[0103] If the verification result is "failed", it indicates that there is a problem with the new resource (such as incomplete decompression or file corruption). The terminal immediately performs a reverse atomic renaming - changing the second storage area, which has become the working area, back to the temporary decompression area, and changing the first storage area of ​​the backup area back to the working area, restoring the previously intact emoji resources to avoid problems such as lost or unusable emojis for users. Then, it returns to the initial version reporting steps, restarts the update process, attempts to obtain and update the latest resources, and executes the rollback strategy.

[0104] Thus, through the complete process design described above, the emoji resource update method provided by this invention achieves fully automated closed-loop management from version reporting, comparison, downloading, verification to switching. Throughout the process, the terminal device and the server collaborate efficiently through the Lightweight Update Engine (LUE), ensuring both the accuracy and integrity of the updated resources. Furthermore, the atomic switching mechanism between the backup area and the working area completely avoids the loss of user emoji resources due to update failures. Simultaneously, the introduction of the breakpoint resume function further improves download efficiency, especially in unstable network environments, significantly saving user data and time costs. In addition, this method has good scalability, easily adapting to different types and sizes of terminal devices to meet diverse application scenario needs.

[0105] Continue to refer to Figure 3 The flowchart 300 illustrates an embodiment of the emoji resource update method applied to a server provided by the present invention, including the following steps:

[0106] Step S301: Receive the version number of the emoji resource sent by the terminal device.

[0107] The server receives the local emoji version number sent by the terminal through the communication interface. This version number is the core input data for the server to determine whether the terminal needs to be updated. It corresponds to the "version reporting" operation in step S201 on the terminal side, forming the first interactive link of "terminal reporting - server receiving".

[0108] Step S302: Determine whether the version number of the emoji resource sent by the terminal device is the same as the version number in the latest version identifier information.

[0109] The server retrieves the "latest version identifier information (ZIP-meta)" stored internally and checks the consistency between the version number in it and the version number sent by the terminal. This check is the key basis for the server to return updated resources in the future, forming a two-way verification with the "version comparison" in step S203 on the terminal side to ensure the accuracy of the version determination.

[0110] Step S303: If yes, send the latest version identification information to the terminal device.

[0111] If the judgment result is "the terminal version is the same as the latest version", the server only sends the latest version identification information (ZIP-meta) to the terminal, informing the terminal that "the local resources are already the latest", and no further download operation is required to avoid invalid data transmission.

[0112] Step S304: In response to receiving a download request from the terminal device, send the latest emoji resources to the terminal device.

[0113] When the server receives a "download request" from the terminal (corresponding to step S2041 on the terminal side), it retrieves the only latest Full-ZIP emoji resource from the storage module and sends the resource to the terminal via the HTTP protocol, triggering the terminal's download process (corresponding to step S2042 on the terminal side), thus realizing the core resource transmission link of server push and terminal reception.

[0114] Step S305: In response to receiving the resume request sent by the terminal device, send the latest undownloaded emoji resources to the terminal device.

[0115] The resume request includes data representing the file range of the latest emoji resources being downloaded. After receiving the resume request from the terminal, the server parses the "file range" data carried in the request, identifies the resource segments that the terminal has already downloaded, and determines the undownloaded data range that needs to be sent, thus preparing for accurate resume transmission.

[0116] Based on the parsed "file range", the server extracts only the part of the ZIP package data that the terminal has not downloaded and sends that part of the data to the terminal instead of resending the complete resource. This enables server support for "resuming interrupted downloads" and corresponds to the resume operation in step S2043 on the terminal side, ensuring the continuity and efficiency of the download process.

[0117] In summary, the emoji resource update method provided by this invention constructs a complete version management closed loop through collaborative interaction between the server and the terminal. The server, as the resource hub, not only maintains the unique version identifier information (ZIP-meta) of the latest emoji resources but also achieves precise control over resource updates by dynamically responding to the terminal's version reporting, download requests, and resume requests. In the version judgment stage, the dual verification mechanism between the server and the terminal ensures the accuracy of version consistency judgment, avoiding invalid updates or resource loss due to version misjudgment. In the resource transmission stage, the server supports both full download and breakpoint resume modes, satisfying the complete requirements of the initial update while optimizing the update experience under unstable network conditions. In particular, the breakpoint resume function, by parsing the file range data sent by the terminal, accurately locates the undownloaded portion, achieving efficient resource resending and significantly saving user traffic and time costs. Furthermore, the server design fully considers scalability and compatibility, adapting to different types and sizes of terminal devices to meet diverse application scenario needs. Through this close collaboration between the server and the terminal, the emoji resource update method provided by this invention not only improves update efficiency and resource accuracy, but also provides users with a more stable and reliable emoji usage experience.

[0118] Continue to refer to Figure 4The diagram illustrates a timing diagram 400 of an embodiment of the emoji resource update method provided by the present invention, which includes the following steps:

[0119] Step S401: The terminal device sends the version number of the emoji resources in the first storage area to the server.

[0120] Step S402: The server determines whether the version number of the emoji resource sent by the terminal device is the same as the version number in the latest version identification information; if so, it sends the latest version identification information to the terminal device.

[0121] Step S403: The terminal device compares the version number of the emoji resources in the work area with the version number in the latest version identifier information to obtain a comparison result; in response to the comparison result indicating that the versions are different, the terminal device downloads the latest emoji resources sent by the server to the cache area.

[0122] Step S404: If the terminal device loses power during the download process, after restarting, the terminal device checks whether there are any unfinished latest emoji resources in the cache; if so, it sends a resume request to the server.

[0123] Step S405: The terminal device downloads the latest emoticon pack resources that have not yet been downloaded from the server to the cache area.

[0124] Step S406: Calculate the CRC32 checksum of the latest emoji resource, and compare the calculated CRC32 checksum with the CRC32 checksum in the latest version identification information. If not, delete the latest emoji resource.

[0125] Step S407: The terminal device decompresses the latest emoji resources in the cache area to the second storage area.

[0126] Step S408: The terminal device sets the first storage area as a backup area and the second storage area as a working area.

[0127] Step S409: The terminal device verifies the integrity of the second storage area and obtains the verification result.

[0128] Step S410: In response to the verification result being passed, the terminal device deletes the file in the third storage area and sets the third storage area as a temporary decompression area.

[0129] Step S411: In response to the verification result being unsuccessful, the terminal device sets the second storage area as a temporary decompression area, sets the first storage area as a working area, and returns to execute step S401.

[0130] The implementation details of this embodiment are similar to those of the embodiments described above, and will not be repeated here.

[0131] In this way, the server (such as the manufacturer's server) and the terminal (such as your child's smartwatch) work together to solve the problems of lagging, being prone to damage, and being insecure in older methods for terminal devices with "small memory and weak performance" by downloading the entire ZIP package and "atomic switching." The terminal only needs to verify the validity of the package (signature / CRC), without parsing the internal files. It features atomic switching between decompression and overwriting directories, power-loss safety, support for resuming interrupted downloads, automatic discarding of compressed packages that fail verification, and no upload of any user data throughout the process, ensuring privacy compliance.

[0132] Experiments show that this type of single file system operation does not require traversing internal files, reducing CPU usage by 70%; after a download is interrupted, the integrity will be checked first on the next startup, and then the interrupted download will continue; the dual-directory atomic switching function ensures that the file system can ensure that a complete resource directory is available at any time when power is lost, achieving "self-healing".

[0133] For the IoT toy project (256 MB Flash, single-core A7), the ZIP package is 10.5 MB.
