[0038] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations or steps, nor must they be executed in the order described. For example, some operations or steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0040] It should be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0041] It should be understood that, in order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish between identical or similar items with substantially identical functions and effects. For example, the first control information and the second control information are only used to distinguish different control information, and their order is not limited.

[0042] Those skilled in the art can understand that the words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not necessarily limit the differences.

[0043] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0044] In the prior art, OTA (Over-The-Air) upgrade technology is widely used in the software update and upgrade of devices. This technology enables devices to directly update software through wireless communication networks without any manual operation by users, thereby greatly improving the convenience and timeliness of updates. However, although OTA upgrade technology brings many conveniences, the user experience still needs to be improved in the current OTA upgrade system. Specifically, users often only receive a simple update prompt message, but cannot intuitively understand the specific upgrade content, new functions after the upgrade, and detailed operation steps. In addition, in most cases, the description of OTA upgrade is still presented to users in the form of plain text. This single information display method does not fully consider the user's demand for more friendly and intuitive information display methods such as graphical interfaces and dynamic demonstrations. For example, when a user receives an OTA upgrade prompt, if the system can provide a detailed upgrade guide, including comparison pictures before and after the upgrade, demonstration videos of new functions, and concise operation steps, then the user can more easily understand the content and significance of the upgrade and smoothly complete the upgrade process. Therefore, in order to further improve the user experience and upgrade efficiency, the OTA upgrade system needs to make more optimizations and innovations in information display methods and user interaction design.

[0045] In order to solve the above problems, this embodiment provides an OTA upgrade control method. In specific implementation, this embodiment first receives OTA upgrade description information, and determines the target format based on the OTA upgrade description information. Then, the OTA upgrade description information is processed based on the target format to obtain upgrade information that conforms to the target format. Finally, an upgrade execution instruction is received, and the latest version of the software corresponding to the upgrade information is downloaded and installed based on the upgrade execution instruction. In this way, the present invention enables users to manage software updates on devices more conveniently and intuitively, while improving the convenience and ease of use of software update operations.

[0046] For example, Figure 2As shown, for the OTA upgrade application scenario of the user's smartphone device terminal, first, the mobile phone software operation and maintenance personnel upload the OTA upgrade description information of the software to the server, and the user's smartphone terminal device receives the OTA upgrade description information from the above server through the wireless communication network. The description contains the available software version, update content and other information. Next, the system of the user's smartphone terminal device processes the received OTA upgrade description information according to a predetermined format and displays it to the user in some form (such as a graphical interface, notification bar message, etc.). After the user sees and understands the OTA upgrade description information on the mobile terminal device, he can choose whether to update the software. At this time, the user can trigger the corresponding operation to perform the update. Finally, if the user agrees to update the software, the system will download and install the latest version of the software from the server according to the OTA upgrade description information. In this way, users can manage software updates on their devices more conveniently and intuitively, while improving the convenience and ease of use of software update operations, providing users with a better software update experience.

[0047] Exemplary Methods

[0048] This embodiment provides an OTA upgrade control method, such as Figure 1 As shown, the specific steps include:

[0049] Step S100: receiving OTA upgrade description information, and determining a target format based on the OTA upgrade description information.

[0050] In this embodiment, the OTA upgrade description information includes OTA upgrade information and target format information of OTA upgrade information. Specifically, the OTA upgrade information may include software version information corresponding to the software OTA upgrade, specific update content included in this OTA upgrade, a list of compatible target device models, the necessity and urgency of the update and upgrade, and the estimated time required for this upgrade. The target format information of the OTA upgrade information is used to control the content display style of the OTA upgrade information. The user terminal device receives the OTA upgrade description information and determines the content display style of the OTA upgrade information through the target format information of the OTA upgrade information in the OTA upgrade description information.

[0051] In one implementation, before receiving the OTA upgrade description information, the OTA upgrade description information is prepared, and format description information is added to the OTA upgrade description information.

[0052] In this embodiment, the target format information of the OTA upgrade information is the format description information. Specifically, Figure 3As shown in steps 1 and 2, the OTA operation and maintenance personnel add the corresponding OTA upgrade description information to the OTA upgrade package through the web terminal, and submit it to the server for subsequent push. The OTA upgrade description information includes OTA upgrade information and format description information. The format description information can support the OTA upgrade information in the description format of text, picture or video. The format description information includes format tags, which are used to mark the font size, height, color, indentation, whether to wrap, and other information for controlling the display style of each paragraph of text. The tag can also be used to mark the size of the picture, the window size of the video, the playback speed, whether to loop, whether it can be paused interactively, whether there is a draggable progress bar, the volume level, and other information for controlling the display style.

[0053] In one implementation, before receiving the OTA upgrade description information, the OTA upgrade description information is checked for correctness, and the OTA upgrade description information is pushed after the check passes.

[0054] In this embodiment, if Figure 3 As shown in steps 3 and 4, after the OTA upgrade description information is uploaded to the server, the server will perform a correctness check on the OTA upgrade description information. Furthermore, the correctness check can be a manual check or an automatic check. The automatic check can be that the server performs parameter parsing on the OTA upgrade description information to obtain the format description information, and performs format conversion on the OTA upgrade information on the server side, and monitors whether there will be abnormal conversion errors to ensure the security and effectiveness of the data structure. The manual check can be that the OTA operation and maintenance personnel inspect and verify the OTA upgrade information after the above format conversion to determine whether the result of the conversion is consistent with the expectation when configuring the format description information. After the correctness check passes and is correct, the OTA upgrade description information containing the format description information will be pushed to the user's terminal device.

[0055] In one implementation, determining the target format based on the OTA upgrade description information specifically includes the following steps:

[0056] Step S101, parsing the OTA upgrade description information to obtain the format description information;

[0057] Step S102: Acquire a format tag in the format description information, and determine the target format based on the format tag.

[0058] When implementing it, Figure 3Step 5: The user terminal device receives the OTA upgrade description information from the server and parses the OTA upgrade description information. After parsing, the format description information in the OTA upgrade description information is obtained. Furthermore, through parsing, the format tag contained in the format description information is obtained, and the format tag is used to determine the target format of the OTA upgrade information, that is, the display style of the OTA upgrade information on the user terminal device.

[0059] Step S200: Process the OTA upgrade description information based on the target format to obtain upgrade information that complies with the target format.

[0060] The user terminal performs format conversion processing on the OTA upgrade information in the OTA upgrade description information by parsing the target format obtained, and obtains the OTA upgrade information in the target format that meets the expectations of the OTA operation and maintenance personnel.

[0061] Specifically, step S200 includes the following steps:

[0062] Step S210: Obtain text information and / or picture information in the OTA upgrade description information;

[0063] Step S220: convert the text information and / or picture information into a format based on the target format to obtain upgrade information that conforms to the target format.

[0064] When implementing it, Figure 3 As shown in steps 5 and 6, the user terminal receives the OTA upgrade description information, wherein the OTA upgrade description information includes the OTA upgrade information, and the OTA upgrade information includes at least text information, picture information or video information. At the same time, the user mobile terminal parses the OTA upgrade description information and obtains the format description information therein, and converts the format of the OTA upgrade information containing at least text information, picture information or video information through the format description information, and finally obtains the OTA upgrade information that conforms to the target format.

[0065] In one implementation, converting the text information and / or picture information into a format based on the target format to obtain upgrade information that conforms to the target format includes the following steps:

[0066] Step S221, obtaining format information corresponding to the target format, wherein the format information includes any one or more of text size, text color, text layout, and image size;

[0067] Step S222: convert the text information and / or picture information into a format based on the format information to obtain upgrade information that conforms to the target format.

[0068] In specific implementation, the user terminal device obtains the format description information by parsing the OTA upgrade description information, and the format description information includes the format information of the target format marked by the format tag, including information such as text size, text color, and text layout for controlling the display style. The tag can also be used to mark the image size, video window size, and other information for controlling the display style. Based on the text and image information marked by the format tag, the OTA upgrade information is format converted to finally obtain the OTA upgrade information that conforms to the target format.

[0069] In one implementation, the receiving of the upgrade execution instruction, and before downloading and installing the latest version of the software corresponding to the upgrade information based on the upgrade execution instruction, further includes: displaying the upgrade information conforming to the target format, and monitoring the upgrade execution instructions issued by the user in real time.

[0070] In this embodiment, if Figure 3 As shown in step 7, through the format conversion, the user terminal device displays the OTA upgrade information, and its display style meets the expectations of the OTA operation and maintenance personnel. At this time, the user terminal device monitors the user behavior and determines whether the user issues an upgrade execution instruction for the terminal device. Furthermore, if the user issues an upgrade execution instruction, the terminal device downloads and installs the latest version of the software corresponding to the OTA upgrade information from the server based on the upgrade execution instruction.

[0071] In summary, in the scenario of OTA upgrade of the device terminal in this embodiment, the operation and maintenance personnel of the device terminal software first upload the OTA upgrade description information containing the format description information and the OTA upgrade information to the server, and perform a correctness check. Subsequently, the user terminal device obtains the OTA upgrade description information carrying the format description information from the server via a wireless network. The user terminal device parses the OTA upgrade description information, converts the format of the OTA upgrade information according to the parsing result, and displays it to the user through the expected graphical interface or notification message. After reviewing and understanding the upgrade details, the user decides whether to update. If the user chooses to update, the system will download and install the latest software version from the server based on this information. This process not only improves the convenience and intuitiveness of users managing device software updates, but also optimizes the user's software update experience.
