[0002] Over the Air (OTA) technology is a technology for downloading data through a wireless network. It has been widely used in the upgrade of vehicles, televisions, mobile phones, tablet computers, set-top boxes and other devices. OTA technology mainly performs automatic upgrades by downloading OTA upgrade packages (it also supports upgrading by copying OTA upgrade packages to SD cards). OTA upgrades are fast and have little impact on data, so OTA upgrades have become the main way to upgrade terminal functions. For example, for vehicles, vehicle manufacturers (Original Equipment Manufacturer, OEM, or original equipment manufacturer) upgrade related hardware or software of vehicles through OTA technology, which is beneficial for manufacturers to reduce recall costs, respond to needs quickly, and improve user experience.

[0003] The image file of the partition in the existing OTA upgrade package fills the entire partition. The size of the OTA upgrade package directly affects the upgrade efficiency, especially the upgrade package flashing time and the upgrade package downloading time. In view of this, a solution that can reduce the size of the OTA upgrade package and thus improve the upgrade efficiency needs to be developed urgently. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0025] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0026] like Figure 1 As shown, an embodiment of the present application provides an over-the-air download upgrade method, the method comprising:

[0027] Step 101: receiving an upgrade request for upgrading N partitions sent by a target device, wherein the upgrade request carries a current version number corresponding to each of the N partitions, wherein N is an integer greater than or equal to 1.

[0028] The over-the-air download upgrade method provided in this application is applied to the OTA platform, which is a platform for providing upgrade packages to the target device. A communication module is installed on the target device, and the target device and the OTA platform communicate based on the communication module installed on the target device. When the target device is a vehicle computer, the communication module is a vehicle telematics processor (TelematicsBox, TBOX). The vehicle computer, i.e., the target device, can send an upgrade request to the OTA platform through TBOX. After the vehicle computer receives the upgrade package fed back by the OTA platform, the vehicle computer system can automatically complete the upgrade based on the upgrade package, and improve the relevant performance of the vehicle, thereby bringing a better operating experience to the user.

[0029] Specifically, the target device may include multiple partitions, each partition corresponds to a functional module, and a list of functional modules to be upgraded is displayed on the function upgrade operation interface of the target device. The user can select the functional modules to be upgraded from the list of functional modules to be upgraded according to their own needs. After determining the functional modules to be upgraded, the target device determines at least one partition to be upgraded based on the correspondence between the functional modules and the partitions, that is, N partitions, and obtains the current version number corresponding to each partition in the N partitions and adds it to the upgrade request.

[0030] Step 102: for each partition of the N partitions, determine the upgrade area corresponding to the partition according to the first file corresponding to the current version number and the second file corresponding to the latest version of the partition.

[0031] After receiving the upgrade request sent by the target device, the OTA platform first obtains the current version number corresponding to each of the N partitions carried in the upgrade request, and then obtains the second file corresponding to the latest version of each partition, and obtains the first file corresponding to the current version number based on the current version number of the partition, so that the upgrade area of ​​the partition can be determined based on the first file and the second file.

[0032] Specifically, the upgrade area corresponding to the partition is part or all of the partition, which needs to be determined based on the first file and the second file. When the upgrade area is part of the partition, only the part of the partition, that is, the part corresponding to the upgrade area, can be upgraded. When the upgrade area is the entire partition, the entire partition needs to be upgraded.

[0033] Step 103: for each partition of the N partitions, determine the image file corresponding to the partition according to the upgrade area corresponding to the partition and the second file.

[0034] After determining the upgrade area corresponding to each partition, the image file corresponding to the partition can be determined based on the upgrade area and the second file. Determining the image file here includes determining the occupied space of the image file and the content of the image file. Specifically, the occupied space is determined based on the upgrade area, and the content is determined based on the second file.

[0035] Step 104: Determine the upgrade package corresponding to the N partitions according to the image file corresponding to each partition in the N partitions, and send the upgrade package to the target device.

[0036] After determining the image file corresponding to each partition, the upgrade packages corresponding to the N partitions can be determined based on the image files corresponding to the N partitions, that is, the N image files are packaged to obtain the upgrade package. After obtaining the upgrade package, the upgrade package is sent to the target device, so that the system of the target device automatically upgrades the N partitions through the upgrade package.

[0037] In the above implementation process of the present application, when an upgrade request for upgrading N partitions is received from the target device, for each of the N partitions, the upgrade area of ​​the partition is determined according to the first file corresponding to the current version number of the partition and the second file corresponding to the latest version, and the image file used to upgrade the partition is determined according to the obtained upgrade area and the second file, and then the upgrade packages corresponding to the N partitions are determined and sent to the target device. The upgrade area corresponding to the partition can be determined based on the file corresponding to the current version and the file corresponding to the latest version, so that the image file can be determined based on the upgrade area and the file corresponding to the latest version. Compared with the image file determined only based on the file of the latest version in the prior art, the size of the partition's image file can be effectively reduced, thereby shortening the download time and flashing time of the upgrade package, and improving the efficiency of over-the-air download upgrades.

[0038] In an optional embodiment of the present application, the first file includes at least one sub-file, the second file includes at least one sub-file, and determining the upgrade area corresponding to the partition according to the first file corresponding to the current version number and the second file corresponding to the latest version of the partition includes:

[0039] Determine a first subfile set according to the subfiles included in the first file and the subfiles included in the second file, wherein the subfiles in the first subfile set belong to the first file but do not belong to the second file;

[0040] When the number of subfiles in the first subfile set is zero, the upgrade area is determined based on the second file;

[0041] When the number of sub-files in the first sub-file set is greater than zero, the upgrade area is determined based on the second file and the first sub-file set.

[0042] Specifically, the first file corresponding to the current version number of the partition, that is, the file used to implement the function corresponding to the partition in the current target device, may include at least one sub-file. Correspondingly, the second file corresponding to the latest version of the partition may also include at least one sub-file. It should be noted that the sub-files included in the first file and the sub-files included in the second file are not in a one-to-one correspondence. For example, the first file includes: sub-file 1, sub-file 2 and sub-file 3, and the second file includes: sub-file 2, sub-file 3 and sub-file 4. That is to say, compared with the current version, the latest version deletes sub-file 1 and adds sub-file 4.

[0043] When determining the upgrade area corresponding to the partition according to the first file and the second file, first determine a first subfile set consisting of subfiles belonging to the first file but not belonging to the second file according to the subfiles included in the first file and the subfiles included in the second file, that is, determine a subfile set consisting of subfiles deleted in the new version. Specifically, an empty subfile set may be first established, and then the subfiles in the first file and the second file may be traversed in sequence, and when a subfile belonging to the first file but not belonging to the second file appears, it may be added to the first subfile set.

[0044] When the number of subfiles in the first subfile set is zero, that is, there is no subfile that belongs to the first file but not to the second file, that is, the latest version does not delete subfiles compared to the current version, it can be determined that the occupied space of the upgrade area of ​​the partition is equal to the occupied space of the second file, that is, the upgrade area is determined based on the second file.

[0045] When the number of subfiles in the first subfile set is greater than zero, that is, there are subfiles that belong to the first file but not to the second file, that is, the latest version has deleted at least one subfile compared to the current version. At this time, the occupied space of the upgrade area of ​​the partition is equal to the sum of the occupied spaces of the second file and the first subfile set, that is, the upgrade area is determined based on the second file and the first subfile set.

[0046] The above implementation scheme of the present application determines a first sub-file set consisting of sub-files in the partition that belong to the first file but not to the second file, and determines the upgrade area of ​​the partition based on the second file or based on the second file and the first sub-file set according to the number of sub-files in the first sub-file set. It can be achieved that the upgrade area in the partition that actually needs to be upgraded is determined according to the comparison of the sub-files in the first file and the second file, so that the image file is subsequently determined based on the upgrade area, thereby eliminating the need to fill the area in the partition that does not need to be upgraded, i.e., the non-upgrade area, with invalid characters in the image file, and the space occupied by the image file can be effectively reduced.

[0047] The following describes how to determine the image file corresponding to a partition based on the upgrade area and the second file corresponding to the partition.

[0048] Based on the above embodiment, the determination of the upgrade area can be divided into the following two cases.

[0049] In the case where the upgrade area is determined based on the second file, determining the image file includes:

[0050] Determine the occupied space corresponding to the image file based on the upgrade area;

[0051] Determine content corresponding to the image file based on the second file.

[0052] Specifically, at this time, compared with the first file, the second file does not delete the sub-files included in the first file. When determining the image file used to upgrade the partition, the space occupied by the image file can be directly determined based on the upgrade area, and the content of the image file can be determined based on the second file. In other words, the image file is completely filled with the second file.

[0053] In the case where the upgrade area is determined based on the second file and the first sub-file set, determining the mirror file includes:

[0054] Determine the occupied space corresponding to the image file based on the upgrade area;

[0055] A filling file is determined based on the occupied space corresponding to the first sub-file set, and content corresponding to the mirror file is determined based on the second file and the filling file.

[0056] Specifically, at this time, compared with the first file, the second file deletes at least one sub-file included in the first file. When determining the image file used to upgrade the partition, it is necessary to determine the space occupied by the image file based on the upgrade area, determine the filler file based on the occupied space corresponding to the first sub-file set, and determine the content corresponding to the image file based on the second file and the filler file. In other words, the image file is partially filled with the second file, and the remaining part is filled with a filler file of the same size as the first sub-file set, and the filler file is composed of invalid data. It should be noted that when the system of the target device detects that the image file includes a filler file composed of invalid data, it can be determined that the sub-file corresponding to the filler file is deleted in the new version.

[0057] According to the above implementation scheme of the present application, when the upgrade area is determined based on the second file, the occupied space corresponding to the image file is determined based on the upgrade area, and the content corresponding to the image file is determined based on the second file; when the upgrade area is determined based on the second file and the first sub-file set, the occupied space corresponding to the image file is determined based on the upgrade area; the fill file is determined based on the occupied space corresponding to the first sub-file set, and the content corresponding to the image file is determined based on the second file and the fill file. The occupied space corresponding to the image file can be determined through the upgrade area, so that when the partition is not completely filled with the first file, compared with the image file size being equal to the partition size, the occupied space of the image file can be made smaller than the total space of the partition, thereby reducing the size of the image file, thereby shortening the download time and upgrade flashing time of the upgrade package composed of the image file, thereby improving the upgrade efficiency and enhancing the user experience.

[0058] In an optional embodiment of the present application, before sending the upgrade package to the target device, the method further includes:

[0059] Sending upgrade package sending prompt information to the target device, wherein the upgrade package sending prompt information is used to prompt the target device to download the upgrade package;

[0060] Sending the upgrade package to the target device includes:

[0061] After receiving the confirmation download information fed back by the target device based on the upgrade package sending prompt information, the upgrade package is sent to the target device.

[0062] Specifically, after the OTA platform obtains the upgrade package and before sending the upgrade package to the target device, it needs to send an upgrade package issuance prompt information to the target device, and the upgrade package issuance prompt information is used to prompt the target device to download the upgrade package. After the user selects the function module to be upgraded on the function upgrade operation interface of the target device and clicks Submit, the target device sends an upgrade request information to the OTA platform. After the OTA platform determines the upgrade package, it sends an upgrade package issuance prompt information to the target device. After the target device receives the upgrade package issuance prompt information, a download window pops up on the function upgrade operation interface. The download window can display the size of the upgrade package, that is, the data traffic required to download the upgrade package, as well as two options of "Yes" and "No" for the user to click. If the user selects the "Yes" option, the target device will feedback the download confirmation information to the OTA platform. Since the download of the upgrade package takes a certain amount of time and consumes data traffic, if the user determines that the current network situation is not suitable for downloading the upgrade package, the "No" option can be selected, and the target device closes the current download window.

[0063] Accordingly, sending the upgrade package to the target device includes: after receiving confirmation download information fed back by the target device based on the prompt information of sending the upgrade package, sending the upgrade package to the target device. In other words, the OTA platform transmits the upgrade package to the target device only after receiving confirmation download information fed back by the user.

[0064] The above implementation scheme of the present application sends the upgrade package to the target device by sending a prompt message to send the upgrade package, and after receiving the confirmation download information fed back by the target device based on the prompt message of sending the upgrade package, sends the upgrade package to the target device. Before transmitting the upgrade package, the consent of the user using the target device can be sought, thereby avoiding the situation where the data traffic caused by directly downloading the upgrade package transmitted by the OTA platform when the target device uses its own data traffic exceeds the remaining data traffic of the target device, thereby improving the user experience.

[0065] In an optional embodiment of the present application, before receiving an upgrade request for upgrading N partitions sent by the target device, the method further includes:

[0066] Determine a list of partitions to be upgraded corresponding to the target device;

[0067] An over-the-air upgrade prompt message carrying the list of partitions to be upgraded is sent to the target device, wherein the over-the-air upgrade prompt message is used to prompt that there are partitions to be upgraded in the target device.

[0068] Specifically, the OTA platform can regularly screen the versions of various functional modules included in the devices connected to it for communication, determine the partitions corresponding to the functional modules that can be upgraded in each device, and then determine the list of partitions to be upgraded corresponding to the target device, and send an over-the-air download upgrade prompt message carrying the list of partitions to be upgraded to the target device to prompt the target device that there are partitions to be upgraded.

[0069] The above implementation scheme of the present application can achieve the purpose of actively prompting the target device to upgrade by sending an over-the-air upgrade reminder message carrying a list of partitions to be upgraded to the target device, so that the user can improve the performance of the target device by downloading and installing the upgrade package.

[0070] In an optional embodiment of the present application, determining the list of partitions to be upgraded corresponding to the target device includes:

[0071] Obtaining the current version number and the latest version number corresponding to each partition included in the target device;

[0072] The partition whose current version number is smaller than the latest version number is determined as a partition to be upgraded, and the partition to be upgraded is added to a partition list to be upgraded, wherein the partition list to be upgraded includes M partitions to be upgraded, where M is greater than or equal to N.

[0073] For the target device, the OTA platform can regularly obtain the current version number and the latest version number corresponding to each partition included in the target device, and compare the current version number and the latest version number of each partition. If the current version number is less than the latest version number, it indicates that the partition needs to be upgraded, and it is determined as the partition to be upgraded and added to the list of partitions to be upgraded.

[0074] Then, the user of the target device can select N partitions to be upgraded from the list of partitions to be upgraded including M partitions to be upgraded, where M is greater than or equal to N. That is, the user can select some or all of the partitions to be upgraded from the list of partitions to be upgraded.

[0075] The above implementation scheme of the present application can obtain the partition that needs to be upgraded in the target device by determining the partition whose current version number is smaller than the latest version number as the partition to be upgraded and adding it to the list of partitions to be upgraded, so as to provide the list of partitions to be upgraded to the target device so that the user of the target device can select the partition that needs to be upgraded from it.

[0076] The above describes the over-the-air upgrade method provided by the embodiment of the present application. The following describes the over-the-air upgrade device provided by the embodiment of the present application in conjunction with the accompanying drawings.

[0077] like Figure 2As shown, an embodiment of the present invention further provides an over-the-air download upgrade device, the device comprising:

[0079] A first determination module 202 is used to determine, for each of the N partitions, an upgrade area corresponding to the partition according to a first file corresponding to the current version number and a second file corresponding to the latest version of the partition;

[0080] The second determination module 203 is used to determine, for each of the N partitions, the image file corresponding to the partition according to the upgrade area corresponding to the partition and the second file.

[0081] The first sending module 204 is used to determine the upgrade package corresponding to the N partitions according to the image file corresponding to each partition in the N partitions, and send the upgrade package to the target device.

[0082] Optionally, the first file includes at least one sub-file, the second file includes at least one sub-file, and the first determining module includes:

[0083] A first determining submodule, configured to determine a first subfile set according to subfiles included in the first file and subfiles included in the second file, wherein subfiles in the first subfile set belong to the first file but do not belong to the second file;

[0084] A second determination submodule, configured to determine the upgrade area based on the second file when the number of subfiles in the first subfile set is zero;

[0085] The third determination submodule is configured to determine the upgrade area based on the second file and the first subfile set when the number of subfiles in the first subfile set is greater than zero.

[0086] Optionally, when the upgrade area is determined based on the second file, the second determination module includes:

[0087] A fourth determination submodule, configured to determine an occupied space corresponding to the image file based on the upgrade area;

[0088] The fifth determining submodule is used to determine the content corresponding to the image file based on the second file.

[0089] Optionally, when the upgrade area is determined based on the second file and the first sub-file set, the second determination module includes:

[0090] A sixth determination submodule, configured to determine an occupied space corresponding to the image file based on the upgrade area;

[0091] The seventh determination submodule is used to determine a filling file based on the occupied space corresponding to the first sub-file set, and determine the content corresponding to the mirror file based on the second file and the filling file.

[0092] Optionally, before sending the upgrade package to the target device, the apparatus further includes:

[0093] A second sending module is used to send upgrade package sending prompt information to the target device, and the upgrade package sending prompt information is used to prompt the target device to download the upgrade package;

[0094] The first sending module is further used for:

[0095] After receiving the confirmation download information fed back by the target device based on the upgrade package sending prompt information, the upgrade package is sent to the target device.

[0096] Optionally, before receiving the upgrade request for upgrading N partitions sent by the target device, the apparatus further includes:

[0097] A third determination module is used to determine a list of partitions to be upgraded corresponding to the target device;

[0098] The third sending module is used to send an over-the-air upgrade prompt message carrying the list of partitions to be upgraded to the target device, wherein the over-the-air upgrade prompt message is used to prompt that there are partitions to be upgraded in the target device.

[0099] Optionally, the third determining module includes:

[0100] An acquisition submodule, used to acquire the current version number and the latest version number corresponding to each partition included in the target device;

[0101] The eighth determination submodule is used to determine the partition whose current version number is smaller than the latest version number as the partition to be upgraded, and add the partition to be upgraded to a partition list to be upgraded, wherein the partition list to be upgraded includes M partitions to be upgraded, and M is greater than or equal to N.

[0102] The over-the-air upgrade device provided by the present application, upon receiving an upgrade request for upgrading N partitions sent by a target device, determines, for each of the N partitions, an upgrade area of ​​the partition according to a first file corresponding to the current version number of the partition and a second file corresponding to the latest version, and determines a mirror file for upgrading the partition according to the obtained upgrade area and second file, and then determines the upgrade packages corresponding to the N partitions and sends them to the target device. The upgrade area corresponding to the partition can be determined based on the file corresponding to the current version and the file corresponding to the latest version, thereby determining the mirror file based on the upgrade area and the file corresponding to the latest version. Compared with the mirror file determined only based on the file of the latest version in the prior art, the size of the mirror file of the partition can be effectively reduced, thereby shortening the download time and flashing time of the upgrade package, and improving the efficiency of over-the-air upgrade.

[0105] like Figure 3 As shown, the electronic device may include: a processor 310, a communication interface 320, a memory 330 and a communication bus 340, wherein the processor 310, the communication interface 320 and the memory 330 communicate with each other through the communication bus 340. The processor 310 may call the logic instructions in the memory 330, and the processor 310 is used to perform the following steps: receiving an upgrade request for upgrading N partitions sent by a target device, wherein the upgrade request carries the current version number corresponding to each of the N partitions, wherein N is an integer greater than or equal to 1; for each of the N partitions, according to the first file corresponding to the current version number and the second file corresponding to the latest version of the partition, determining the upgrade area corresponding to the partition; for each of the N partitions, according to the upgrade area corresponding to the partition and the second file, determining the image file corresponding to the partition; according to the image file corresponding to each of the N partitions, determining the upgrade package corresponding to the N partitions, and sending the upgrade package to the target device.

[0106] In addition, the logic instructions in the above-mentioned memory 330 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on this understanding, the technical solution of the present application can be essentially or partly embodied in the form of a software product that contributes to the prior art, and the computer software product is stored in a storage medium, including several instructions to enable a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present application. The aforementioned storage medium includes: various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk.

When the computer program is executed by a processor, the various processes of the above-mentioned over-the-air download upgrade method embodiment are implemented, and the same technical effect can be achieved.
