Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of device remote upgrading, in particular to a terminal differential upgrading method, a terminal differential upgrading device, a device and a medium. BACKGROUND

[0002] With the rapid development of the Internet of Things and intelligent devices, OTA (Over-The-Air) technology, as a technology for remotely updating software on devices through wireless networks, has been widely applied in the fields of smart phones, smart home devices, automotive electronic systems, etc. The main advantage of OTA technology is that it can achieve remote maintenance and functional upgrading of devices without relying on physical connections, thereby improving the performance and security of devices.

[0003] Traditional OTA updating methods usually include full upgrade and differential upgrade. Full upgrade refers to downloading the entire firmware or the entire new version of the software package to the device, completely replacing the old version. Although this method is simple and direct, it requires downloading a large amount of data, occupying a large amount of network bandwidth and storage space, especially in the case of limited device storage resources, which may cause a large burden. Differential upgrade is a more efficient updating method, which only downloads the difference between the new and old versions, thereby reducing data transmission volume, shortening updating time, and reducing the occupation of device resources.

[0004] However, even if differential upgrade is adopted, the generated differential package may contain update content of multiple functional modules. For users, they may not need to update all functional modules, but are only interested in certain modules. The traditional differential upgrade method cannot meet this individualized demand, resulting in unnecessary waste of resources and time consumption. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a terminal differential upgrading method, a terminal differential upgrading device, a device and a medium, which divides the software system to be upgraded into multiple independent functional modules, determines the modules to be upgraded by comparing the original version files and the upgraded version files of each functional module. Users can independently select the target functional modules that need to be upgraded, and the server generates a customized differential package containing specific modules according to user selection, so that the terminal does not need to be forced to accept all contents in the entire differential package. The terminal only needs to download the modular differential package selected by the user, avoiding the waste of bandwidth caused by downloading the entire differential package, and reducing the occupation of device storage space. Due to the reduction of data volume for downloading and installation, the time required for the upgrading process is also significantly shortened.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work falls within the scope of protection of the present application.

[0047] First, the application scenarios applicable to the present application are introduced. The present application can be applied to the technical field of device remote upgrade.

[0048] With the rapid development of the Internet of Things and smart devices, OTA (Over-The-Air) technology, as a technology for remotely updating software on devices through wireless networks, has been widely applied in the fields of smart phones, smart home devices, automotive electronic systems, etc. The main advantage of OTA technology is that it can realize remote maintenance and functional upgrade of devices without relying on physical connections, thereby improving the performance and security of devices.

[0049] It is found through research that the traditional OTA update method usually includes full upgrade and differential upgrade. Full upgrade refers to downloading the entire firmware or the entire new version of the software package to the device, completely replacing the old version. Although this method is simple and direct, it requires downloading a large amount of data, occupying a large amount of network bandwidth and storage space, especially in the case of limited device storage resources, which may cause a large burden. Differential upgrade is a more efficient update method, which only downloads the difference between the new and old versions, thereby reducing data transmission volume, shortening update time, and reducing the occupation of device resources.

[0050] However, even if the differential upgrade is adopted, the generated differential package can contain the update content of multiple functional modules. For users, it can not be necessary to update all functional modules, but only some of them are interested. The traditional differential upgrade method cannot meet this individualized demand, resulting in unnecessary waste of resources and time consumption.

[0051] Based on this, the embodiments of the present application provide a differential upgrade method to improve upgrade efficiency, reduce resource consumption and improve user experience.

[0052] Please refer to Figure 1 , Figure 1 A flowchart of a differential upgrade method provided by the embodiments of the present application. The differential upgrade method provided by the embodiments of the present application is applied to a server, as shown in Figure 1 The differential upgrade method comprises the following steps.

[0053] S101, when receiving the upgrade request for the software system sent by the terminal, obtaining the original version file and the upgrade version file corresponding to each functional module in the software system.

[0054] Here, the terminal can be a smart phone, a smart home device, or a car electronic system, etc., which is not limited by the present application. The software system can be the operating system of the terminal, responsible for controlling and coordinating the terminal; it can also be a certain application program in the terminal, a software developed to meet the various application needs of users, such as office software, games, professional software, etc.; which is not limited by the present application. For example, when the terminal is a smart phone, the software system can be the operating system of the smart phone, such as Android, iOS, HarmonyOS, etc., and the software system can also be a certain application program in the smart phone. The functional module refers to an independent unit or component designed to achieve a specific function. For example, when the software system is the operating system of the smart phone, the functional module can be a performance optimization module, a security patch module, and a UI update module, etc. When the software system is a certain application software in the smart phone, the functional module can be the user interface module, the network communication module and the data processing module of the application software, etc. The original version file refers to the version file currently running by the functional module. The upgrade version file refers to the new version file after the original version of the functional module is optimized in function, repaired in defect or added with new features.

[0055] For the above step S101, when receiving the upgrade request for the software system sent by the terminal, the software system is modularized and subdivided, and the original version file and the upgrade version file corresponding to each functional module in the software system are obtained. Here, the original version file and the upgrade version file are both image files of the software system, and the image is a complete file copy of the original version file and the upgrade version file of the functional module.

[0056] S102, compare the differences between the original version file and the upgraded version file corresponding to each functional module, determine the module to be upgraded from multiple functional modules, and generate a difference content mapping table corresponding to the software system based on the module to be upgraded.

[0057] Here, the module to be upgraded refers to the functional module that needs to be upgraded. The module to be upgraded can be determined by comparing the differences between the original version file and the upgrade version file. The difference content mapping table records the difference content, module identifier, module name, and other information for each module to be upgraded in the software system.

[0058] Regarding step S102 above, in specific implementation, the original version file and the upgraded version file corresponding to each functional module are compared for differences. The modules to be upgraded are identified from multiple functional modules; these are the modules that differ from the original version file and need to be upgraded. Then, a difference mapping table corresponding to the software system is generated based on the modules to be upgraded.

[0059] As an optional embodiment, regarding step S102 above, the step of comparing the differences between the original version file and the upgraded version file corresponding to each functional module to determine the module to be upgraded from multiple functional modules includes:

[0060] Step 1021: For each functional module, divide the original version file and the upgraded version file corresponding to the functional module according to the preset storage space size to obtain multiple original version storage blocks and multiple upgraded version storage blocks.

[0061] Here, the preset storage space size can be 512 bytes or 4KB, and this application does not specifically limit it. Each storage block can store a certain amount of data.

[0062] Regarding step 1021 above, in specific implementation, for each functional module, the original version file and the upgraded version file corresponding to the functional module are divided according to the preset storage space size to obtain multiple original version storage blocks and multiple upgraded version storage blocks.

[0063] Step 1022: For each upgraded version storage block, determine the storage block to be compared from multiple original version storage blocks based on the storage block identifier of the upgraded version storage block.

[0064] Since each divided storage block has a unique block identifier (Block ID), the corresponding block can be obtained through the block identifier. For step 1022, in a specific implementation, for each upgraded version storage block, the corresponding to-be-compared storage block is determined from the plurality of original version storage blocks based on the block identifier of the upgraded version storage block.

[0065] Step 1023: performing difference comparison on the upgraded version storage block and the to-be-compared storage block, and if it is determined that there is a difference between the upgraded version storage block and the to-be-compared storage block, determining the upgraded version storage block as a difference storage block and the function module as the to-be-upgraded module.

[0066] For step 1023, in a specific implementation, the upgraded version storage block and the corresponding to-be-compared storage block are compared, and if it is determined that there is a difference between the upgraded version storage block and the to-be-compared storage block, the upgraded version storage block is determined as a difference storage block, and the function module is determined as a to-be-upgraded module.

[0067] Specifically, for step 1023, the difference comparison between the upgraded version storage block and the to-be-compared storage block includes:

[0068] calculating a first hash value of the upgraded version storage block and a second hash value of the to-be-compared storage block; and if the first hash value is different from the second hash value, it is considered that there is a difference between the upgraded version storage block and the to-be-compared storage block.

[0069] For the above two steps, in a specific implementation, a first hash value of the upgraded version storage block and a second hash value of the to-be-compared storage block are calculated. Here, the hash value can be calculated by MD5 or SHA-1, which is not limited in the present application. Then, the first hash value of the upgraded version storage block is compared with the second hash value of the to-be-compared storage block, if the first hash value of the upgraded version storage block is the same as the second hash value of the to-be-compared storage block, it is considered that the data stored in the two storage blocks is the same. If the first hash value of the upgraded version storage block is different from the second hash value of the to-be-compared storage block, it is considered that there is a difference between the upgraded version storage block and the to-be-compared storage block. Please refer to Table 1, which is a storage block hash value comparison example table provided by the embodiment of the present application, as shown in Table 1, the to-be-compared storage block corresponding to the upgraded version storage block is determined through the block identifier of the upgraded version storage block, the hash values of the two storage blocks are calculated respectively and compared, if the hash values are the same, it is considered that the data stored in the two storage blocks is the same, if the hash values are different, it is considered that there is a difference between the two storage blocks.

[0070] Table 1: A storage block hash value comparison example table

[0071]

[0072] Further, for the above step S102, the difference content mapping table corresponding to the software system is generated based on the to-be-upgraded module, comprising:

[0073] A: For each to-be-upgraded module, the difference content of the difference storage block corresponding to the to-be-upgraded module is determined.

[0074] Here, the difference content of the difference storage block refers to the specific data change part between the storage blocks corresponding to the new and old versions of the file due to modification, addition or deletion. The core goal of determining these differences is to extract only the change part, rather than transmitting the entire block, thereby reducing the size of the upgrade package.

[0075] For the above step A, in specific implementation, for each to-be-upgraded module, since the upgrade version storage block that has differences with the original version has been determined as the difference storage block in the above step, the original version storage block corresponding to the difference storage block is determined according to the identifier of the difference storage block, and then the difference content between the two is determined by a difference calculation method. Here, the difference calculation method can choose binary difference method or structured difference method, which is not limited by the present application.

[0076] B: The module identifier corresponding to the to-be-upgraded module, the storage block identifier of the difference storage block corresponding to the to-be-upgraded module, and the difference content of the difference storage block corresponding to the to-be-upgraded module are stored in a mapping relationship to obtain the difference content mapping table.

[0077] For the above step B, in specific implementation, the module identifier corresponding to the to-be-upgraded module, the storage block identifier of the difference storage block corresponding to the to-be-upgraded module, and the difference content of the difference storage block corresponding to the to-be-upgraded module are stored in a mapping relationship, that is, the difference content mapping table. In this way, the mapping relationship between the functional module and the difference storage block is recorded in the difference content mapping table, that is, the position of the difference block in the functional module and the content of the difference block, and the difference content of the corresponding difference storage block can be directly determined from the difference content mapping table by the module identifier corresponding to the target upgrade module when generating the differential upgrade package corresponding to the target upgrade module. Please refer to Table 2, which is a difference content mapping example table provided by an embodiment of the present application, as shown in Table 2, the difference content mapping table can include the module identifier and module name corresponding to the to-be-upgraded module, the storage block identifier of the difference storage block, the difference content of the difference storage block, the identifier of the difference content, and the file name involved in the difference content.

[0078] Table 2: A difference content mapping example table

[0079]

[0080] Here, the differences between the original version file and the upgraded version file are all from the three types of operations on the file, i.e., modification, addition, and deletion of the upgraded version. The target version file of the module to be upgraded (ModuleID) involves modification of multiple files (FileName), and each file (FileName) involved records a mapping relationship (block_diffs) with the difference storage block (BlockID), which includes the difference content (diff_content) and the storage block identifier (block_id) of the difference storage block. Subsequent users can select the module to be upgraded, and then map the module identifier ModuleID of the module selected by the user to the specific difference content from the difference content mapping table to generate a new difference upgrade package.

[0081] S103, send the upgrade information of the module to be upgraded to the terminal, receive and respond to the module upgrade request of the target upgrade module sent by the terminal, and generate the difference upgrade package corresponding to the target upgrade module based on the difference content mapping table.

[0082] Here, the upgrade information of the module to be upgraded includes the module name, upgrade description, upgrade type, and size information of the module to be upgraded, which is not limited in this application.

[0083] For the above step S103, when the module to be upgraded that needs to be upgraded is determined, the upgrade information of the module to be upgraded is sent to the terminal. At this time, the terminal displays the upgrade information after receiving the upgrade information of the module to be upgraded, and the user can select the target upgrade module according to the upgrade requirement. The terminal can generate the module upgrade request of the target upgrade module according to the module selection result of the user and return it to the server. The server receives and responds to the module upgrade request of the target upgrade module sent by the terminal, and generates the difference upgrade package corresponding to the target upgrade module based on the difference content mapping table generated in the above step. The difference upgrade package is a data package that only contains the difference part of the new and old version files, which is used to upgrade the old version file to the new version by "patching" instead of transmitting the complete new file. Its core goal is to reduce data transmission and improve upgrade efficiency. The difference upgrade package contains the update package of the difference content, which can significantly reduce the size of the update package compared to full update, thereby reducing bandwidth consumption and storage occupation.

[0084] As an optional embodiment, for the above step S103, the difference upgrade package corresponding to the target upgrade module is generated based on the difference content mapping table, which includes:

[0085] Step 1031, based on the target module identifier corresponding to the target upgrade module, obtaining the difference content of the difference storage block corresponding to the target upgrade module from the difference content mapping table.

[0086] Since the difference content mapping table generated by the above steps stores the difference content of the difference storage block corresponding to each module to be upgraded, the difference content can be directly determined from the difference content mapping table through the target module identifier corresponding to the target upgrade module selected by the user. For the above step 1031, in specific implementation, the target module identifier corresponding to the target upgrade module selected by the user is obtained, and the difference content of the difference storage block corresponding to the target upgrade module is extracted from the difference content mapping table based on the target module identifier.

[0087] Step 1032, packing the difference content of the difference storage block corresponding to the target upgrade module to obtain the differential upgrade package corresponding to the target upgrade module.

[0088] For the above step 1032, after determining the difference content of the difference storage block corresponding to the target upgrade module from the difference content mapping table, the difference content of the difference storage block corresponding to the target upgrade module is packed, and the differential upgrade package corresponding to the target upgrade module is generated.

[0089] S104, sending the differential upgrade package to the terminal, so that the terminal uses the differential upgrade package to perform differential upgrade on the target upgrade module.

[0090] For the above step S104, in specific implementation, the generated differential upgrade package is sent to the terminal, and after the terminal receives the differential upgrade package, the target upgrade module is upgraded using the differential upgrade package. In this way, the user can independently select the functional module to be updated, generate a customized differential package according to the user's selection, and also avoid the waste of bandwidth caused by downloading the entire differential package by the terminal, and reduce the occupation of the terminal storage space.

[0091] As an optional embodiment, after the differential upgrade package is sent to the terminal, the differential upgrade method further includes:

[0092] I: calculating a third hash value corresponding to the differential upgrade package.

[0093] II: receiving a fourth hash value sent by the terminal, and comparing the third hash value with the fourth hash value to verify the differential upgrade package.

[0094] The fourth hash value is generated by the terminal based on the received differential upgrade package.

[0095] For the above step I-step II, in a specific implementation, after the server sends the differential upgrade package to the terminal, the third hash value corresponding to the differential upgrade package is calculated. The terminal also calculates the fourth hash value based on the received differential upgrade package at the same time of receiving the differential upgrade package, and returns the fourth hash value to the server. The server receives the fourth hash value sent by the terminal, and compares the third hash value with the fourth hash value. In this way, after generating and sending the differential upgrade package, the integrity of the sent differential upgrade package and the received differential upgrade package by the terminal is verified through the hash value.

[0096] The differential upgrade method provided by the embodiment of the application is applied to a server. First, when receiving an upgrade request for a software system sent by a terminal, the original version file and the upgrade version file corresponding to each function module in the software system are obtained. Then, the original version file and the upgrade version file corresponding to each function module are compared to determine a to-be-upgraded module from the plurality of function modules, and a differential content mapping table corresponding to the software system is generated based on the to-be-upgraded module. The upgrade information of the to-be-upgraded module is sent to the terminal, a module upgrade request for a target upgrade module sent by the terminal is received and responded to, and a differential upgrade package corresponding to the target upgrade module is generated based on the differential content mapping table. Finally, the differential upgrade package is sent to the terminal, so that the terminal performs differential upgrade on the target upgrade module by using the differential upgrade package.

[0097] The software system to be upgraded is divided into a plurality of independent function modules in the application, and the to-be-upgraded module is determined by comparing the original version file and the upgrade version file of each function module. The user can autonomously select a target function module to be upgraded, the server generates a customized differential package containing a specific module according to the user selection, and the terminal does not need to be forced to accept all the contents in the entire differential package. The terminal only needs to download the modularized differential package selected by the user, thereby avoiding the bandwidth waste caused by downloading the entire differential package and reducing the occupation of the device storage space. Since the amount of data to be downloaded and installed is reduced, the time required for the upgrade process is also significantly shortened. The modularized design enables each function module to be updated independently, and also reduces the risk that the entire software system cannot be normally upgraded due to a problem of a single module.

[0098] Please refer to Figure 2 , Figure 2 A flowchart of a differential upgrade method provided by another embodiment of the application. The differential upgrade method provided by another embodiment of the application is applied to a terminal, as shown in Figure 2 The differential upgrade method includes the following steps.

[0099] S201, in response to a user's upgrade operation on a software system, an upgrade request for the software system is generated and sent to a server.

[0105] S204, receiving the target upgrade module corresponding to the differential upgrade package sent by the server, and upgrading the target upgrade module using the differential upgrade package.

[0106] In the step S203-S204, in a specific implementation, after the user selects the target upgrade module in the terminal, the terminal generates a module upgrade request of the target upgrade module and sends it to the server. The terminal receives the differential upgrade package corresponding to the target upgrade module sent by the server, and upgrades the target upgrade module by using the differential upgrade package.

[0107] The differential upgrade method provided by the embodiment of the application is applied to a terminal. First, in response to a user's upgrade operation on a software system, an upgrade request for the software system is generated and sent to a server. Upgrade information of a to-be-upgraded module sent by the server is received, and the upgrade information of the to-be-upgraded module is displayed. In response to a user's selection operation on any to-be-upgraded module, a target upgrade module is determined from the to-be-upgraded module. A module upgrade request of the target upgrade module is generated and sent to the server. A differential upgrade package corresponding to the target upgrade module sent by the server is received, and the target upgrade module is upgraded by using the differential upgrade package.

[0108] The software system to be upgraded is divided into a plurality of independent functional modules in the application. By comparing the original version file and the upgrade version file of each functional module, the to-be-upgraded module is determined. The user can autonomously select a target functional module to be upgraded. The server generates a customized differential package containing a specific module according to the user selection. The terminal does not need to be forced to accept all the contents in the entire differential package. The terminal only needs to download the modular differential package selected by the user, thereby avoiding the bandwidth waste caused by downloading the entire differential package and reducing the occupation of the device storage space. Since the amount of data to be downloaded and installed is reduced, the time required for the upgrade process is also significantly shortened. The modular design enables each functional module to be updated independently, and also reduces the risk that the entire software system cannot be normally upgraded due to a problem of a single module.
