[0028] The present application is described below in conjunction with embodiments:

[0029] According to one aspect of an embodiment of the present application, a method for upgrading a device is provided. Optionally, in this embodiment, the method for upgrading the device can be applied to: Figure 1 In the hardware environment composed of the server 101 and the terminal device 103 shown in FIG. Figure 1As shown, the server 101 is connected to the terminal 103 via a network, and can be used to provide services for the terminal device or the application installed on the terminal device. The application can be a video application, an instant messaging application, a browser application, an educational application, a game application, etc. A database 105 may be set up on the server or independently of the server to provide data storage services for the server 101, for example, a game data storage server. The above-mentioned network may include, but is not limited to, a wired network and a wireless network, wherein the wired network includes, for example, a local area network, a metropolitan area network, and a wide area network; the wireless network includes, for example, Bluetooth, WIFI, and other networks that implement wireless communication; the terminal device 103 may be a terminal configured with an application program, and may include, but is not limited to, at least one of the following: a mobile phone (such as an Android phone, an iOS phone, etc.), a laptop computer, a tablet computer, a PDA, a MID (Mobile Internet Devices), a PAD, a desktop computer, a smart TV, an intelligent voice interaction device, a smart home appliance, a vehicle-mounted terminal, an aircraft, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a mixed reality (MR) terminal, and other computer devices; the above-mentioned server may be a single server, a server cluster consisting of multiple servers, or a cloud server.

[0030] Combination Figure 1 As shown, the upgrade method of the above-mentioned device can be executed by an electronic device, which can be a terminal device or a server. The upgrade method of the above-mentioned device can be implemented by the terminal device or the server respectively, or by the terminal device and the server together.

[0031] The above is only an example and is not specifically limited in this embodiment.

[0032] Optionally, as an optional implementation, as Figure 2 As shown, the upgrade method of the above device includes:

[0033] S202, in response to a device upgrade request, obtaining an upgrade data packet, wherein the device upgrade request is used to request an upgrade of the device to be upgraded, and the upgrade data packet is used to upgrade the device to be upgraded;

[0034] Optionally, in an embodiment of the present application, the above-mentioned device upgrade request includes but is not limited to requesting software updates, hardware improvements or security patches, etc., specifically, it may include the serial number or identifier of the device, current software and hardware version information, user preferences or specific upgrade requirements, etc. The above-mentioned upgrade data packet may include but is not limited to a new version of software or firmware for the device to be upgraded, security patches or vulnerability fixes, new configuration files or setting options, hardware upgrade guidance or instructions, and the above-mentioned device to be upgraded may include but is not limited to personal computers, laptops, tablets, smart phones, smart watches, other wearable devices, home automation equipment, smart appliances, industrial control systems, etc.

[0035] In an exemplary embodiment, it is assumed that there is a gateway for obtaining a device upgrade request initiated by an upgrade initiator, and then sending the device upgrade request to the device to be upgraded. If the device to be upgraded determines that the device can currently perform the upgrade operation and receive the upgrade data packet, it informs the gateway. The gateway then sends a response message to the upgrade initiator that the device to be upgraded can receive the upgrade data packet. The upgrade initiator sends the upgrade data packet to the gateway, and then the gateway forwards the upgrade data packet to the device to be upgraded.

[0036] S204, determining a target channel model from at least one channel model, and determining a target transmission rate from at least one transmission rate, wherein the target channel model is used to specify a target channel for transmitting the upgrade data packet, and the target transmission rate represents a transmission rate of the upgrade data packet in the target channel;

[0037] Optionally, in an embodiment of the present application, the above-mentioned channel model is used to express the anti-interference ability of the channel, and can also be understood as the interference model of the channel, including but not limited to a continuous strong interference model, an occasional interference model, a bottom noise lift model, an idle model, etc. The above-mentioned transmission rate can be flexibly set, including but not limited to determining by sending a test data packet in advance, for example, it refers to the amount of data transmitted per unit time, usually in bits per second (bps). The determination of the transmission rate is usually based on the following factors: channel bandwidth, the maximum frequency range that the channel can support; signal-to-noise ratio (SNR): the ratio of signal strength to background noise intensity; modulation mode, different modulation modes (such as QPSK, 16QAM, 64QAM, etc.), the above-mentioned target channel may include but is not limited to additive white Gaussian noise (AWGN) channel, Rayleigh channel, Rician channel, etc., and different channels correspond to different above-mentioned channel models.

[0038] In an exemplary embodiment, there are two channels, among which the interference situation of channel A can be expressed as a continuous strong interference model, and the interference situation of channel B can be expressed as an occasional interference model. Since the anti-interference ability of channel B is stronger than that of channel A, channel B is selected as the target channel model. Then, the target transmission rate is determined by sending a test data packet. It is assumed that the channel bandwidth B is preferably 20MHz and the signal-to-noise ratio SNR is preferably 30dB. In this case, the 64QAM modulation method is also used. According to the Shannon formula, the above-mentioned target transmission rate C=B\log_2(1+SNR) is obtained.

[0039] S206, performing a division operation on the upgrade data packet to obtain a group of first data blocks, wherein the size of the first data block is related to the target channel parameter and the target transmission rate of the target channel;

[0040] Optionally, in an embodiment of the present application, the above-mentioned target channel parameters may include but are not limited to channel bandwidth, signal-to-noise ratio, delay, etc.

[0041] In an exemplary embodiment, it is assumed that the size of the first data block is 10 data frames, and the upgrade data packet includes 100 data frames. Therefore, after receiving the upgrade data packet, the gateway may divide the upgrade data packet into 10 first data blocks.

[0042] It can be understood that when the channel anti-interference ability is strong and the target transmission rate is fast, the size of the first data block can be dynamically expanded. Conversely, if the channel anti-interference ability is weak and the target transmission rate is slow, the size of the first data block can be dynamically reduced to ensure that the integrity and consistency of the data are not destroyed, so as to improve the efficiency and reliability of the upgrade data packet transmission.

[0043] S208, sending a group of first data blocks to the device to be upgraded in sequence according to the block sequence numbers, and determining a first transmission confirmation result returned by the device to be upgraded, wherein the first transmission confirmation result is used to indicate whether the device to be upgraded has received each first data block in the group of first data blocks;

[0044] Optionally, in an embodiment of the present application, the block numbers of different first data blocks are different, and the first transmission confirmation result may include but is not limited to whether the data block is successfully received, the integrity check result of the data block, possible error codes or descriptions, etc.

[0045] In an exemplary embodiment, the above-mentioned first data blocks are sent to the device to be upgraded in sequence. After the device to be upgraded receives each first data block, it will check each data frame in the first data block and provide real-time feedback on the first transmission confirmation result corresponding to each first data block. The first transmission confirmation results corresponding to different first data blocks may be the same or different.

[0046] S210, when the first transmission confirmation result indicates that the number of transmission times of a first data block in a group of first data blocks that has not been received by the device to be upgraded meets a preset threshold, updates at least one of the size of the first data block, the target channel model and the target transmission rate, and sends the upgrade data packet according to the updated size of the first data block, the target channel model and the target transmission rate.

[0047] Exemplarily, in the process of sending the above-mentioned first data blocks in sequence according to the above-mentioned block sequence numbers, after the device to be upgraded receives each first data block, it will check each data frame in the first data block to determine whether there are any lost data frames. For example, if each first data block includes 10 consecutive data frames, if it is found that the 4th first data block is missing the 5th frame sequence number, the device to be upgraded will return the above-mentioned first transmission confirmation result corresponding to the first data block to the gateway in real time, including "the data frame with frame number 5 in the first data block with block number 4 is lost, requesting retransmission".

[0048] In an exemplary embodiment, Figure 3 is a schematic diagram of an optional device upgrade method according to an embodiment of the present application. The device upgrade method proposed in the present application can be applied to the OTA upgrade process of the device firmware of the vehicle system, etc. Figure 3 As shown, including but not limited to:

[0049] S302, collecting and analyzing channel interference models (the above-mentioned channel models): scanning the communication status of each communication channel, and analyzing each channel interference model, for example: continuous strong interference channel model, sporadic interference model, bottom noise lifting model, idle model and other channel model information.

[0050] S304, channel selection: based on the comparison and evaluation of all available channel interference models, the optimal communication model is selected. The upgrade initiator interacts with the device to be upgraded through a preset channel and switches to the target channel corresponding to the target channel model for subsequent OTA upgrade interaction.

[0051] S306, transmission rate and power matching: the upgrade initiator controls the gateway to negotiate with the device to be upgraded to initiate rate sniffing, and combines different interactive feedback to match the current optimal transmission rate and transmission power under the premise of meeting communication reliability.

[0052] S308, generate OTA upgrade strategy, model feature evaluation: determine the transmission effect and interference evaluation according to different transmission rates, different transmit powers, and different channels, classify the upgrade strategy according to different expected upgrade effects, and use the target channel, target transmit power, and target transmission rate as the final OTA upgrade strategy.

[0053] S310, according to the upgrade strategy tendency, adjust the data transmission strategy: divide the upgrade data packet into data blocks to obtain the above-mentioned group of first data blocks, wherein each first data block will contain multiple frames of data according to the block size, confirm the transmission result in blocks, and perform accurate retransmission based on the bitmap based on the transmission confirmation result. When the data transmission of a certain interval frame group fails, the gateway sets the frame sequence number lost in the interval frame group in the above-mentioned first response bitmap, and the device to be upgraded re-uploads the frame data that failed to be transmitted according to the set first response bitmap frame sequence number. Figure 4 It is a schematic diagram of another optional device upgrade method according to an embodiment of the present application. The bitmap representation is shown in Figure 4. Further, the size of the first data block is adjusted according to the current upgrade strategy tendency. When the upgrade strategy evaluates performance first, large data blocks are used to improve transmission performance. When the upgrade strategy evaluates stability first, small data blocks are used to improve transmission robustness.

[0054] S312, dynamic adjustment of OTA upgrade strategy: When the frequency of retransmission or failure during OTA upgrade under the current upgrade strategy reaches the set threshold, the upgrade strategy adjustment process is initiated to improve the communication stability of OTA upgrade. When the transmission is stable and reliable, the transmission strategy is adjusted to improve the model transmission efficiency. The upgrade strategy is based on the optimization of upgrade efficiency or transmission stability, and it conducts limited self-adjustment based on multiple dimensional parameters and data indicators. It takes into account the efficiency and reliability of OTA upgrades of the device to be upgraded.

[0055] Through the embodiments of the present application, it is ensured that when the OTA upgrade environment of the device to be upgraded is good, the upgrade process can be completed with higher communication efficiency, thereby improving the upgrade speed; when the OTA upgrade conditions of the device to be upgraded are not good, the stable upgrade strategy can be preferentially selected to complete the device upgrade; the upgrade strategy switching process is automatically completed, and the optimal upgrade strategy is automatically and dynamically adjusted to adapt. The OTA upgrade strategy can be adaptively adjusted through multiple dimensions such as channel, rate, interaction mechanism, and transmission power, so that the device to be upgraded has both higher upgrade efficiency and improved reliability of OTA upgrades in complex environments.

[0056] In another exemplary embodiment, the upgrade process of the above-mentioned device to be upgraded may include but is not limited to:

[0057] S1, the upgrade initiator initiates an OTA upgrade request for the device firmware to the device to be upgraded through the gateway;

[0058] S2: The gateway forwards the OTA upgrade request to device firmware A, and the gateway collects and analyzes the available channel models;

[0059] S3, the gateway and the device to be upgraded negotiate to determine the target channel model between the gateway and the device to be upgraded;

[0060] S4, the gateway and the device to be upgraded negotiate, using the test packet data to match the current optimal transmission rate (target transmission rate) and transmission power between the gateway and the device to be upgraded;

[0061] S5, the gateway determines the upgrade strategy based on the target channel, the current optimal transmission rate and the transmission power;

[0062] S6, the gateway first determines the size of each data block according to the target channel, the current optimal transmission rate and the transmission power, and divides the upgrade data packet according to the size of the data block;

[0063] S7, the gateway sends data blocks to the device to be upgraded in sequence, each data block has a data block sequence number;

[0064] S8, the device to be upgraded feeds back the transmission result (including the frame number of the lost data frame) to the gateway in real time, the gateway determines the data frame to be retransmitted according to the frame number, and queries whether there is data to be retransmitted in the local cache of the gateway last time, if so, the data to be retransmitted is directly retransmitted to the device to be upgraded, if not, the response bitmap (the flag bit of the frame number of the data to be retransmitted is set to 1) is sent to the upgrade initiator, the upgrade initiator sends the data to be retransmitted to the gateway based on the response bitmap, and the gateway retransmits the data to be retransmitted to the device to be upgraded;

[0065] S9, during the transmission process, the gateway adjusts the size of the data block in real time according to the data block reception quality (bit error rate, data loss rate, etc.) in the transmission confirmation result fed back by the device to be upgraded and the interference of the channel (signal-to-noise ratio). For example, at the first moment, it is determined that each data block contains 8 frames. At the second moment, due to the large channel interference and poor data block reception quality, the size of the remaining data blocks that have not been sent will be adjusted. For example, the data frames contained in the remaining data blocks are adjusted to 6 frames, thereby reducing the size of each data block and increasing the number of data blocks.

[0066] S10, the gateway presets a data block retransmission count threshold for each data block and an upgrade package retransmission count threshold for the entire upgrade package. If the data block retransmission count exceeds the data block retransmission count threshold, or the entire upgrade package retransmission count exceeds the upgrade package retransmission count threshold, execute the above S3 to S5 (redetermine the upgrade strategy).

[0067] Through the embodiment of the present application, an upgrade data packet is obtained in response to a device upgrade request, wherein the device upgrade request is used to request an upgrade of the device to be upgraded, and the upgrade data packet is used to upgrade the device to be upgraded; a target channel model is determined from at least one channel model, and a target transmission rate is determined from at least one transmission rate, wherein the target channel model is used to specify a target channel for transmitting the upgrade data packet, and the target transmission rate represents the transmission rate of the upgrade data packet in the target channel; a partitioning operation is performed on the upgrade data packet to obtain a group of first data blocks, wherein the size of the first data block is related to the target channel parameter of the target channel and the target transmission rate; a group of first data blocks are sent to the device to be upgraded in sequence according to the block sequence number, and a first transmission confirmation result returned by the device to be upgraded is determined, wherein the first transmission confirmation result is used to indicate the device to be upgraded. Whether the upgrade device has received each first data block in a group of first data blocks; when the first transmission confirmation result indicates that the number of transmission times of the first data blocks in a group of first data blocks that have not been received by the device to be upgraded meets the preset threshold, at least one of the size of the first data block, the target channel model and the target transmission rate is updated, and the upgrade data packet is sent according to the updated size of the first data block, the target channel model and the target transmission rate.

The gateway compares the transmission test result with the preset transmission conditions. The preset transmission conditions may include an upper limit of the bit error rate and a lower limit of the data reception strength. If the transmission test result meets the preset transmission conditions, the current initial transmission rate is determined as the target transmission rate, indicating that the device to be upgraded can stably operate at this rate under the current conditions.

[0075] Optionally, in an embodiment of the present application, the first response bitmap is a data structure used to mark whether each first data block has been received.

[0076] In an exemplary embodiment, first, a bitmap is created for each data block, and each bit in the bitmap corresponds to a frame in the data block. If the data frame is successfully transmitted, the corresponding bit is set to 0; if the data frame fails to be transmitted, the corresponding bit in the first response bitmap is set to 1.

[0077] As an optional scheme, the above method also includes: sending a target data frame to the above-mentioned device to be upgraded, wherein the above-mentioned first data block is composed of at least one data frame, and the above-mentioned at least one data frame includes the above-mentioned target data frame; receiving a second response message sent by the above-mentioned device to be upgraded, wherein the above-mentioned second response message is used to indicate whether the above-mentioned target data frame has been completed received, and the above-mentioned first response message includes the above-mentioned second response message; when the above-mentioned second response message indicates that the above-mentioned target data frame has been completed received, determining the target frame sequence number of the above-mentioned target data frame, and adjusting the second response bitmap according to the above-mentioned target frame sequence number, wherein the above-mentioned second response bitmap is used to mark whether each data frame in the above-mentioned first data block has been completed received, and the above-mentioned first response bitmap includes the above-mentioned second response bitmap.

[0078] Specifically, the data frames in the data block are sent to the device to be upgraded in sequence; after receiving each data block, the device to be upgraded checks the integrity and correctness of the data frame. If a data frame is found to have failed to be transmitted, the sequence number of the frame is recorded; according to the sequence number of the frame that failed to be transmitted recorded by the device to be upgraded, the corresponding bit in the first response bitmap is set to 1, and the second response bitmap is sent to the gateway; the gateway only retransmits the data frames that failed to be transmitted according to the frame sequence number set in the second response bitmap.

[0079] As an optional scheme, when the first transmission confirmation result indicates that the number of transmission times of the data blocks in the group of first data blocks that have not been received by the device to be upgraded meets a preset threshold, the size of the first data block, the target channel model and at least one of the target transmission rate are updated, and the upgrade data packet is sent according to the updated size of the first data block, the target channel model and the target transmission rate, including: when the first transmission confirmation result indicates that the number of transmission times of the first data blocks in the group of first data blocks that have not been received by the device to be upgraded meets a first preset threshold, the size of the first data block is updated from the first size to the second size; The method comprises the steps of: performing a division operation on the upgrade data packet according to the second size to obtain a group of second data blocks; sending the group of second data blocks to the device to be upgraded in sequence according to the block sequence numbers, and determining a second transmission confirmation result returned by the device to be upgraded, wherein the second transmission confirmation result is used to indicate whether the device to be upgraded has received each of the second data blocks in the group of second data blocks; when the second transmission confirmation result indicates that the number of times that the upgrade data packet has not been received by the device to be upgraded meets a second preset threshold, updating at least one of the target channel model and the target transmission rate, and sending the upgrade data packet according to the updated target channel model and the target transmission rate.

[0080] Optionally, in an embodiment of the present application, the first size is different from the second size.

After receiving the data blocks, the device to be upgraded will return a transmission confirmation result in real time. The transmission confirmation result indicates which data blocks in the first data blocks have not been successfully received. If the number of times the unreceived data blocks are sent reaches or exceeds a preset threshold (first preset threshold), the size of the first data block needs to be updated from the first size to the second size to improve the reliability of data transmission.

[0082] Furthermore, the upgrade data packet is re-divided according to the new size (second size) to obtain a group of new data blocks (second data blocks). Then, the second data blocks are sent to the device to be upgraded in the order of their block numbers, and the device is waited for to return a second transmission confirmation result. If the second transmission confirmation result indicates that the number of times the upgrade data packet has not been successfully received reaches or exceeds another preset threshold (second preset threshold), further adjustments are required. The target channel model and / or target transmission rate can also be updated, and the upgrade data packet is resent according to the updated channel model and transmission rate to adapt to changes in network conditions and improve the efficiency and reliability of data transmission.

[0083] Through the embodiments of the present application, the data transmission process is optimized by dynamically adjusting the size of the data block, the channel model and the transmission rate, ensuring that the data can be reliably transmitted to the device to be upgraded. The use of this adaptive upgrade strategy can improve the success rate of data transmission.

[0086] In an exemplary embodiment, the device to be upgraded confirms the data block sent by the gateway and returns the first transmission confirmation result to the gateway. If the number of times the unreceived data block is sent reaches this threshold, subsequent operations will be triggered, that is, when the target channel parameters indicate that the channel is in a high interference state, a new data block size (second size) is determined, which is smaller than the original size (first size), and the amount of data transmitted each time is reduced to reduce the probability of transmission failure due to interference. Conversely, when the target channel parameters indicate that the channel is in a low interference state, the system will increase the size of the data block (second size), which is larger than the original size (first size), to utilize the good conditions of the target channel and increase the amount of data transmitted each time to improve transmission efficiency.

[0087] As an optional solution, the method further includes: in response to the device upgrade request, obtaining the upgrade data packet; determining the target channel model from the at least one channel model, determining the target transmission rate from the at least one transmission rate, and determining the target transmission power from at least one transmission power, wherein the target transmission power represents the transmission power of the upgrade data packet in the target channel; performing a division operation on the upgrade data packet to obtain a group of first data blocks, wherein the size of the first data blocks is related to the target transmission power; sending the group of first data blocks to the device to be upgraded in sequence according to the block sequence number, and determining the first transmission confirmation result returned by the device to be upgraded; when the first transmission confirmation result indicates that the number of times the first data blocks in the group of first data blocks that have not been received by the device to be upgraded meet a preset threshold, updating at least one of the size of the first data block, the target channel model, the target transmission rate and the target transmission power, and sending the upgrade data packet according to the updated size of the first data block, the target channel model, the target transmission rate and the target transmission power.

[0088] Optionally, in an embodiment of the present application, the target transmission power may include but is not limited to the transmission power of a gateway, the transmission power of a device to be upgraded, etc.

[0090] Furthermore, the device to be upgraded feeds back the transmission result (including the frame number of the lost data frame) to the gateway in real time, and the gateway determines the data frame to be retransmitted according to the frame number, and queries whether there is data to be retransmitted in the local cache of the gateway last time. If so, the data to be retransmitted is directly retransmitted to the device to be upgraded. If not, the response bitmap (the flag bit of the frame number of the data to be retransmitted is set to 1) is sent to the upgrade initiator, and the upgrade initiator sends the data to be retransmitted to the gateway based on the response bitmap, and the gateway retransmits the data to be retransmitted to the device to be upgraded; during the transmission process, the gateway adjusts the size of the data block in real time according to the data block reception quality (bit error rate, data loss rate, etc.) in the transmission confirmation result fed back by the device to be upgraded and the interference situation (signal-to-noise ratio) of the channel; the gateway presets a data block retransmission number threshold for each data block and an upgrade package retransmission number threshold for the entire upgrade package. If the data block retransmission number exceeds the data block retransmission number threshold, or the entire upgrade package retransmission number exceeds the upgrade package retransmission number threshold, the above S3 to S5 (redetermine the upgrade strategy).
