Many vehicles today have in-vehicle infotainment systems based on the Android platform, which require continuous upgrades. To eliminate the need for customers to visit dealerships for upgrades each time, Over-the-Air (OTA) technology has emerged. This technology has undergone several stages of development. With the evolution of wireless communication technology and device functionality, OTA has expanded from basic data transmission to a modern technology for remotely upgrading device firmware, operating systems, and applications. Summary of the Invention

[0007] The upgrade includes: first upgrading the content of partitions A and B, and then upgrading offline resources.

[0008] The upgrade of the A / B partition content includes calling the native Android update_engine.

[0009] After the A / B partition upgrade is completed, the slot flag is set to the backup partition, and then a reboot is performed.

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0032] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0033] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0034] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.

[0035] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0036] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.

[0037] In related technologies, OTA (Over-the-Air) technology is a technology that remotely transmits data or updates software via a wireless network. Its most common applications are in smartphones, tablets, smart home devices, automobiles, and other IoT devices, used for system or firmware updates, application updates, configuration file and settings updates, bug fixes, and security patches.

[0038] Android OTA seamless updates work by dividing the device's storage into two system partitions, typically called partition A and partition B. Android's A / B partitions (Seamless Updates) are a partition structure used for seamless operating system updates, primarily designed to allow devices to update without interruption, reducing the risk of update failures. Each partition contains the operating system image file and other related data. When the device is running, the system boots from only one partition (e.g., partition A). During a system update, the update package is downloaded and applied to inactive partitions (e.g., partition B), without affecting the currently used partition (partition A). After the update is complete, the system marks the new partition as the active partition and boots from that partition on the next reboot.

[0039] Differential upgrades are a technique that reduces update package size and speeds up system updates. Compared to full upgrades, differential upgrades only include modifications relative to the current device version, rather than the entire system image. This technique is particularly suitable for large-scale OTA updates, significantly saving network bandwidth, reducing download time, and minimizing storage space usage during update installation. In addition to these features, differential upgrades generate a "DeltaPackage" based on two different versions of files. This package contains only the differences between the old and new versions. When an update is installed on the device, the system updates existing system files using the DeltaPackage, rather than replacing the entire file.

[0040] The technical problem solved by this application is: the new upgrade method proposed in this invention is applicable to Android N and later platforms. Because the partition of OTA upgrade is only read-only, but third-party applications need resources that can be read and written, the native upgrade process cannot upgrade such cases. This invention effectively solves the need to upgrade some third-party application resources when performing differential upgrades on Android P and later versions of the platform by expanding the upgrade process.

[0041] To address at least one of the technical problems existing in the aforementioned related technologies, this invention provides a method and system for upgrading offline resources based on a dual-partition mechanism. Wherein: Figure 1 A flowchart illustrating a method for upgrading offline resources based on a dual-partition mechanism, provided in an embodiment of the present invention; Figure 2 This is a schematic diagram illustrating an optional specific implementation process of a method for upgrading offline resources based on a dual-partition mechanism, provided in an embodiment of the present invention. Figure 3 The following is a flowchart illustrating the specific upgrade process in an embodiment of the present invention for upgrading offline resources based on a dual-partition mechanism. Figure 4 A structural block diagram of a system for upgrading offline resources based on a dual-partition mechanism, provided in an embodiment of the present invention; Figure 5This is a structural block diagram of an electronic device provided in an embodiment of the present invention.

[0042] As an embodiment of the present invention, see Figure 1 This invention provides a method for upgrading offline resources based on a dual-partition mechanism, comprising:

[0043] The original upgrade solution is extended by adding ext4 formatted A / B partitions to store offline resource data.

[0044] Include offline resource data in the update_engine upgrade scope and upgrade it.

[0045] The present invention provides a method for upgrading offline resources based on a dual-partition mechanism. First, it extends the native upgrade scheme by adding ext4 formatted A / B partitions to store offline resource data. Then, it incorporates the offline resource data into the update_engine upgrade scope and upgrades it. By expanding the upgrade process, this invention effectively solves the need to additionally upgrade some third-party application resources during differential upgrades on Android P and later versions.

[0046] Among them, see Figure 2 The upgrade includes: first upgrading the content of partitions A and B, and then upgrading offline resources.

[0047] Upgrading the A / B partitions includes calling the native Android update_engine.

[0048] After the A / B partitions are upgraded, the slot flag is set to the backup partition, and then a reboot is performed.

[0049] After the system restarts, the A / B partitions will be switched to the target version.

[0050] Before the boot animation ends, ota_service detects the flag, sets system properties to start the upgrade process, triggers the execution of the script in init.rc, upgrades the third-party offline resources stored in partitions A / B, and upgrades the resources to the specified location of the third-party application.

[0051] Upgrading the third-party offline resources stored within partitions A and B includes:

[0052] During the upgrade, the versions of third-party resources are checked. If the target version of the resource is found to be inconsistent with the version of the resource in partitions A / B, the subsequent upgrade process is initiated.

[0053] The specific upgrade process includes:

[0054] The upgrade package is parsed through ota_service, the upgrade status is obtained from update_engine and init, and the status is returned to ota.apk;

[0055] `update_engine` is the native A / B upgrade service used to upgrade payload.bin to the backup partition.

[0056] In the Android system, the init process is the first user-space process in the system. It is started by the kernel after the system boots up and is responsible for starting the ota_service.

[0057] Upgrading partitions A and B involves parsing the upgrade package via ota_service, obtaining the upgrade status from update_engine and init, and returning the status to ota.apk.

[0058] Specifically, the new upgrade method proposed in this invention is applicable to Android N and later platforms. This is because the partition for OTA upgrades is only read-only, but third-party applications require read-write resources. The native upgrade process cannot upgrade such cases. This invention effectively solves the need to upgrade some third-party application resources during differential upgrades on Android P and later platforms by expanding the upgrade process.

[0059] This technical solution is an extension of the original upgrade solution. It requires the addition of an ext4 formatted A / B partition to store offline resource data. For convenience, it is named the tmp partition and included in the update_engine upgrade scope.

[0060] The upgrade process is divided into two parts: first upgrade the content of partitions A and B, and then upgrade the offline resources.

[0061] 1. For upgrading partitions A and B, simply call the native Android update_engine. After the dual-partition upgrade is complete, set the slot flag to the backup partition and then reboot.

[0062] 2. After the system restarts, the system partition has been switched to the target version. Before the boot animation ends, ota_service detects the flag, sets system properties to start the upgrade process, triggers the execution of the script in init.rc, upgrades the third-party offline resources stored in the tmp partition, and upgrades the resources to the specified location of the third-party application, thereby realizing the upgrade of offline resources.

[0063] During the upgrade, the versions of third-party resources will be checked. When the target version of the resource is found to be inconsistent with the version of the resource in the tmp partition, the subsequent upgrade process will be started. It is not possible to start the upgrade simply by setting the version in the tmp partition to be newer, because when the SOC needs to be rolled back, there are compatibility issues with third-party applications, and the target version of the resource needs to be rolled back synchronously.

[0064] In the specific upgrade process, the role of each functional module is as follows: Figure 3 As shown.

[0065] The ota_service service is used to parse the upgrade package, obtain the upgrade status from update_engine and init, and return the status to ota.apk.

[0066] The `update_engine` is the native A / B upgrade service used to upgrade payload.bin to the backup partition.

[0067] In the Android system, the init process is the first user-space process in the system. It is started by the kernel after the system boots up and is responsible for starting the ota_service.

[0068] The beneficial effects of the technical solution of this invention are as follows:

[0069] This addresses the limitation of Android platforms not being able to upgrade read / write partitions, enabling in-vehicle infotainment systems to upgrade third-party offline resources, thus improving system functionality. Furthermore, because differential upgrades only compare the differences between two versions, the resulting differential package size does not change significantly, keeping it within an acceptable range.

[0070] As an embodiment of the present invention, see Figure 4 This invention provides a system for upgrading offline resources based on a dual-partition mechanism, used to implement the above method, comprising:

[0071] The extension unit is used to expand upon the original upgrade scheme by adding ext4 formatted A / B partitions to store offline resource data.

[0072] The upgrade unit is used to include offline resource data within the scope of the update_engine upgrade and upgrade it.

[0073] The system for upgrading offline resources based on a dual-partition mechanism provided by this invention first extends the original upgrade scheme by adding ext4 formatted A / B partitions to store offline resource data; then, the offline resource data is included in the update_engine upgrade scope and upgraded accordingly. This invention effectively solves the need to additionally upgrade some third-party application resources during differential upgrades on Android P and later versions of the platform by expanding the upgrade process.

[0075] This technical solution is an extension of the original upgrade solution. The extension unit adds an ext4 formatted A / B partition to store offline resource data. For convenience, it is named the tmp partition and included in the update_engine upgrade scope.

[0076] The upgrade process of the upgrade unit provided in this embodiment of the invention is divided into two parts: first, upgrade the content of partitions A / B, and then upgrade the offline resources.

[0077] 1. For upgrading partitions A and B, simply call the native Android update_engine. After the dual-partition upgrade is complete, set the slot flag to the backup partition and then reboot.

[0078] 2. After the system restarts, the system partition has been switched to the target version. Before the boot animation ends, ota_service detects the flag, sets system properties to start the upgrade process, triggers the execution of the script in init.rc, upgrades the third-party offline resources stored in the tmp partition, and upgrades the resources to the specified location of the third-party application, thereby realizing the upgrade of offline resources.

[0079] During the upgrade, the versions of third-party resources will be checked. When the target version of the resource is found to be inconsistent with the version of the resource in the tmp partition, the subsequent upgrade process will be started. It is not possible to start the upgrade simply by setting the version in the tmp partition to be newer, because when the SOC needs to be rolled back, there are compatibility issues with third-party applications, and the target version of the resource needs to be rolled back synchronously.

[0080] In the specific upgrade process, the upgrade unit has multiple functional modules, namely the ota_service service module, the update_engine service module, and the init process module. The functions of each module are as follows: Figure 3 As shown.

[0081] The ota_service module is used to parse the upgrade package, obtain the upgrade status from update_engine and init, and return the status to ota.apk;

[0082] The update_engine service module is a native A / B upgrade service used to upgrade payload.bin to the backup partition;

[0083] The init process module is the first user-space process in the system. It is started by the kernel after the system boots up and is responsible for starting the ota_service.

[0084] The beneficial effects of the technical solution of this invention are as follows:

[0085] This addresses the limitation of Android platforms not being able to upgrade read / write partitions, enabling in-vehicle infotainment systems to upgrade third-party offline resources, thus improving system functionality. Furthermore, because differential upgrades only compare the differences between two versions, the resulting differential package size does not change significantly, keeping it within an acceptable range.
