[0058] Please refer to Figure 1 , which shows a schematic diagram of the architecture of a firmware upgrade system provided by an embodiment of the present application. The firmware upgrade system may include: a terminal device 10 and a first server 20.

[0059] The terminal device 10 may be any type of smart device, which may be a mobile terminal or a relatively fixed terminal. For example, the terminal device 10 may be a mobile phone, a computer, a game console, an e-reader, a wearable device, a smart home device, a vehicle, an Internet of Things device, etc.

[0060] The first server 20 communicates and interacts with the terminal device 10 to implement the firmware upgrade of the terminal device 10. For example, the first server 20 can provide the terminal device 10 with a data packet required for the firmware upgrade, or provide the address of the data packet required for the firmware upgrade. For another example, the first server 20 can retry or resume the firmware upgrade process of the terminal device 10 according to an error that occurs during the firmware upgrade process of the terminal device 10.

[0061] Alternatively, if Figure 1 As shown, the firmware upgrade system may further include a second server 30. The second server 30 communicates and interacts with the first server 20 to provide background management for the firmware upgrade of the terminal device 10. For example, the second server 30 may display the progress and status of the firmware upgrade, initiate the firmware upgrade, upload the data packets required for the firmware upgrade, and the like.

[0062] like Figure 1 As shown, the first server 20 and the second server 30 can both be components of the developer center console. The firmware developer can upload the data packets required for the firmware upgrade, view the progress and status of the firmware upgrade, etc. through the second server 30, and can also manage the transmission method of the data packets required for the firmware upgrade through the first server 20.

[0063] In one example, the firmware upgrade method provided in the embodiment of the present application is implemented through OTA (Over-the-Air) technology, and the terminal device 10 and the first server 20 communicate based on the MQTT (Message Queuing Telemetry Transport) protocol; based on this, the first server 20 can be implemented as an MQTT Broker (MQTT proxy server), and the second server 30 can be implemented as an OTA server. Of course, the devices in the firmware upgrade system can also communicate based on other communication protocols, such as HTTP (HyperText Transfer Protocol), LwM2M (Lightweight M2M, Lightweight M2M (Machine-to-Machine, Device to Device)) protocol, etc., and the embodiment of the present application does not limit this.

[0064] Please refer to Figure 2, which shows a flowchart of a firmware upgrade method provided by an embodiment of the present application. The firmware upgrade method can be applied to Figure 1 In the firmware upgrade system shown in FIG. 1 , for example, the firmware upgrade method may be performed by Figure 1 The firmware upgrade system shown in the figure is executed by the terminal device. Figure 2 As shown, the firmware upgrade method includes the following steps (steps 110 to 120):

[0065] Step 110: The terminal device receives m data slices from the first server on n first channels between the terminal device and the first server;

[0066] Step 120: The terminal device obtains a firmware data packet according to the m data slices; wherein the firmware data packet is used to upgrade the target firmware in the terminal device.

[0067] The embodiment of the present application establishes multiple channels (i.e., communication channels) between the terminal device and the first server, and the multiple channels include n first channels, where n is a positive integer. Among them, the first channel can be a channel dedicated to transmitting data fragments, or a channel for transmitting data fragments and other data (such as log information, etc.). The multiple channels between the terminal device and the first server can also include other channels other than the first channel, such as the second channel and the third channel. Please refer to the following embodiments for the introduction and description, which will not be repeated here.

[0068] The firmware data packet required for the target firmware upgrade is divided into m data slices, where m is a positive integer. For example, the first server divides the firmware data packet into m data slices, or the second server divides the firmware data packet into m data slices. Among them, a first channel is used to transmit one or more data slices. In an embodiment of the present application, the data slices transmitted in two different first channels may be the same or different. Taking a first channel as an example in which a data slice is transmitted, and the data slices transmitted in any two different first channels are different, the above n is equal to m. Of course, in the case where the number of data slices transmitted by a first channel is multiple, or the data slices transmitted in two different first channels are the same, the above n may not be equal to m, such as n may be less than m or n may be greater than m, and the embodiment of the present application does not limit this.

[0069] After receiving the m data slices, the terminal device can obtain a firmware data packet based on the m data slices. For example, the terminal device can first perform a legitimacy check on the m data slices, and if the legitimacy check is successful, assemble the m data slices into a firmware data packet. Among them, the legitimacy check includes but is not limited to an integrity check and a correctness check. Among them, the integrity check can be implemented through CRC (Cyclic Redundancy Check), hash check, etc.; the correctness check can be implemented through data format check, data packet sequence number check, firmware version check, encryption / decryption check, etc. During the legitimacy check process, if there are one or more data slices that fail the legitimacy check, the terminal device can send a first error message to the first server, so that the first server retransmits the one or more data slices, or causes the first server to retransmit all data slices.

[0070] In summary, the firmware upgrade method provided in the embodiment of the present application divides the firmware data packet required for the firmware upgrade into multiple data slices, and the terminal device receives the multiple data slices from the first server through multiple channels, and then obtains the firmware data packet according to the multiple data slices to further realize the firmware upgrade. The embodiment of the present application transmits multiple data slices through multiple channels, which can improve the efficiency of data transmission, so as to further improve the efficiency of firmware upgrade. In addition, multiple channels are established between the terminal device and the first server, and when a channel is abnormally connected, the transmission task can be undertaken through other channels, which can improve the stability and reliability of data transmission, so as to further improve the stability and reliability of firmware upgrade.

[0071] In one example, the firmware upgrade method may further include the following steps (step 130):

[0072] Step 130: The terminal device sends connection indication information to the first server on the second channel between the terminal device and the first server.

[0073] The connection indication information is used to determine whether the communication connection based on the first channel is abnormal. For example, the connection indication information can be information that the terminal device needs to send to the first server regularly in the heartbeat mechanism, such as a heartbeat packet. In an embodiment of the present application, the connection indication information is transmitted through a second channel, and the second channel and any one of the first channels are two different channels. Based on this, the transmission of the connection indication information and the transmission of the data fragments can be isolated from each other to avoid conflicts or mutual influences between the two.

[0074] In one example, the firmware upgrade method may further include the following steps (step 140):

[0075] Step 140: The terminal device sends error log information to the first server on the third channel between the terminal device and the first server.

[0076] Among them, the error log information is used to indicate that an error occurred in the terminal device during the firmware upgrade process of the target firmware. Optionally, the error log information may also include the time when the error occurred, the cause of the error, etc. In an embodiment of the present application, the error log information is transmitted through a third channel, and the third channel and any one of the first channels are two different channels. Based on this, the transmission of the error log information and the transmission of the data slices can be isolated from each other to avoid conflicts or mutual influences between the two. Optionally, the third channel and the second channel can be the same channel, or the third channel and the second channel can be two different channels.

[0077] For example, Figure 3 As shown, three types of channels are established between the terminal device and the first server, namely, the first channel, the second channel and the third channel; wherein the first channel can be used to transmit data fragments, the second channel can be used to transmit connection indication information, and the third channel can be used to transmit error log information.

[0078] To summarize, the firmware upgrade method provided in the embodiment of the present application establishes multiple types of channels between the terminal device and the first server, and each type of channel transmits different types of data to achieve isolation between different types of data transmission. For example, the transmission of data segmentation is isolated from the transmission of error log information, connection indication information, etc., to avoid conflicts or mutual influences between different types of data transmission, which helps to improve the stability and reliability of data segment transmission, thereby improving the stability and reliability of firmware upgrades.

[0079] In one example, the firmware upgrade method may further include the following steps (step 100):

[0080] Step 100: The terminal device sends m data transmission topics to the first server on n first channels.

[0081] Among them, a data transmission topic is used to indicate the transmission of a data slice, and a first channel is also used to transmit one or more data transmission topics. In an embodiment of the present application, for a first channel, if a terminal device sends a data transmission topic to a first server on the first channel, the first server sends the data slice indicated by the data transmission topic to the terminal device on the first channel; if the terminal device sends multiple data transmission topics to the first server on the first channel, the first server sends the data slices indicated by the multiple data transmission topics to the terminal device on the first channel.

[0082] Optionally, the terminal device may send m data transmission topics to the first server at the same time, and the first server may return the data slices (m data slices) indicated by the m data transmission topics to the terminal device in sequence, or may return the data slices (m data slices) indicated by the m data transmission topics to the terminal device at the same time. Optionally, the terminal device may send m data transmission topics to the first server in sequence, and continue to send the next order of data transmission topics after receiving each data slice from the first server. Optionally, the terminal device may send m data transmission topics to the first server at the same time, and the first server may also return the data slices (m data slices) indicated by the m data transmission topics to the terminal device at the same time. The terminal device may receive the data slices (m data slices) indicated by the m data transmission topics at the same time or in sequence.

[0083] In an example, taking the example of a terminal device sending a data transmission topic to the first server in sequence, the above step 100 may include the following steps (steps 1011 to 1012):

[0084] Step 1011: On the first first channel, the terminal device sends s1 data transmission topics to the first server; where s1 is a positive integer;

[0085] Step 1012: The terminal device receives s from the first server on the tth first channel. t After data sharding, on the t+1th first channel, s is sent to the first server. t+1 data transmission topics until s is sent to the first server on the nth first channel n data transmission topics; where t is a positive integer less than n; s t is a positive integer, and s1 to s n The sum is equal to m.

[0086] The terminal device may sort the n first channels, for example, according to the identification serial numbers of the n first channels. Starting from the first channel of the n first channels, the terminal device sends s1 data transmission topics to the first server on the first first channel, and then the terminal device receives s1 data slices (data slices indicated by the s1 data transmission topics) from the first server on the first first channel; in response to receiving s1 data slices on the first first channel, the terminal device sends s2 data transmission topics to the first server on the second first channel, and then the terminal device receives s2 data slices (data slices indicated by the s2 data transmission topics) from the first server on the second first channel... The terminal device receives s1 data slices on the tth first channel. t After data sharding, send s to the first server on the t+1th first channel.t+1 data transmission topics... and so on, until the terminal device sends s to the first server on the nth first channel. n The terminal device then receives the s data transmission topic from the first server on the nth first channel. n Data shards (s n data shards indicated by the data transfer topics).

[0087] In one example, taking the case where the terminal device simultaneously sends a data transmission topic to the first server, the above step 100 may include the following steps (step 1021):

[0088] Step 1021: The terminal device sends data transmission topics to the first server on n first channels simultaneously; wherein the sum of the numbers of data transmission topics transmitted on the n first channels is equal to m.

[0089] In this example, after the terminal device sends m data transmission topics, it can receive m data fragments at the same time or sequentially.

[0090] In an example, taking the example that the terminal device simultaneously sends a data transmission topic to the first server, but sequentially receives data slices from the first server, the above step 110 may include the following steps (steps 111 to 112):

[0091] Step 111: The terminal device receives s from the first server on the tth first channel. t data shards; where t is a positive integer less than n; s t is a positive integer;

[0092] Step 112: The terminal device receives s t After data sharding, on the t+1th first channel, s is received from the first server. t+1 data shards until s is received from the first server on the nth first channel n data shards; among them, s1 to s n The sum is equal to m.

[0093] The terminal device may sort the n first channels, for example, according to the identification serial numbers of the n first channels. Starting from the first channel of the n first channels, the terminal device receives s1 data slices from the first server on the first first channel; in response to receiving s1 data slices on the first first channel, the terminal device receives s2 data slices from the first server on the second first channel... After receiving s t After data shards, s is received from the first server on the t+1th first channel.t+1 data shards until receiving s from the first server on the nth first channel n data shards.

[0094] Optionally, in the embodiment of the present application, the s transmitted on the tth first channel t The priority of the data fragment is higher than that of the s transmitted on the t+1th first channel. t+1 That is to say, when the terminal device transmits m data transmission topics to the first server in sequence, the data transmission topics corresponding to the data slices with higher priorities can be sorted according to the priorities of the data slices, and the data transmission topics corresponding to the data slices with lower priorities can be transmitted first; when the terminal device receives the m data slices from the first server in sequence, the data slices can also be sorted according to the priorities of the data slices, and the data slices with higher priorities can be received first, and the data slices with lower priorities can be received.

[0095] Optionally, the priority ranking of the m data slices is consistent with the ranking of the influence of the m data slices on the device operating status of the terminal device, that is, the greater the influence of the data slice on the device operating status, the higher the priority of the data slice; or, the priority ranking of the m data slices is consistent with the ranking of the influence of the m data slices on the firmware upgrade process of the target firmware, that is, the greater the influence of the data slice on the firmware upgrade process, the higher the priority of the data slice.

[0096] In summary, in the firmware upgrade method provided in the embodiment of the present application, the terminal device can send data transmission topics to the first server and receive data fragments from the first server in a variety of ways, thereby improving the flexibility of data transmission.

[0097] In one example, after the above step 110, the following step (step 150) may also be included:

[0098] Step 150: The terminal device receives s on the tth first channel. t If there are data fragments, fragment confirmation information is sent to the first server.

[0099] The fragment confirmation information transmitted on the tth first channel is used to indicate that the terminal device has received the s transmitted on the tth first channel. t data shards; t is a positive integer less than n; s t Is a positive integer.

[0100] The first server may set a preset confirmation time for the slice confirmation information of the data slice, for example, the duration of the preset confirmation time is a preset duration (such as 1 second or 2 seconds, etc.), and the time when the first server sends the data slice is taken as the starting time. After the first server sends one or more data slices to the terminal device on any first channel, if the first server does not receive the slice confirmation information from the terminal device on the first channel within the preset confirmation time, it is considered that the data slice transmission on the first channel has failed, and the first server may retransmit the data slice on the first channel.

[0101] Optionally, the preset confirmation time may be a non-fixed confirmation time, which may be determined according to the number of times the first server has not received the fragment confirmation information. For example, for a certain first channel, on the first channel, if the first server has not received the fragment confirmation information within the preset confirmation time, the first server retransmits the data fragment to the terminal device, and then the first server sets a shorter preset confirmation time, and uses the new preset confirmation time as the basis for whether to retransmit.

[0103] It should be understood that the steps performed by the first server in the above-mentioned embodiment can be implemented as a firmware upgrade method on the first server side.

[0105] Among them, a first channel is used to transmit one or more data slices; m data slices are used to obtain firmware data packets, and the firmware data packets are used to upgrade the target firmware in the terminal device; n is a positive integer, and m is a positive integer.

[0106] In one example, the firmware upgrade method may further include the following steps (step 420):

[0107] Step 420: The first server receives m data transmission topics from the terminal device on n first channels, wherein one data transmission topic is used to indicate the transmission of one data segment, and one first channel is also used to transmit one or more data transmission topics.

[0114] In summary, the firmware upgrade method provided in the embodiment of the present application divides the firmware data packet required for the firmware upgrade into multiple data slices, and the first server sends the multiple data slices to the terminal device through multiple channels, so that the terminal device obtains the firmware data packet according to the multiple data slices, so as to further realize the firmware upgrade. The embodiment of the present application transmits multiple data slices through multiple channels, which can improve the efficiency of data transmission, so as to further improve the efficiency of the firmware upgrade. In addition, multiple channels are established between the terminal device and the first server, and when a channel is abnormally connected, the transmission task can be undertaken through other channels, which can improve the stability and reliability of data transmission, so as to further improve the stability and reliability of the firmware upgrade.

[0115] Below, an example is used to introduce and illustrate the firmware upgrade method provided in an embodiment of the present application.

[0116] like Figure 3 As shown, multiple channels can be established between the terminal device and the first server. When the terminal device communicates with the first server through multiple channels, it can specify the address and port number of the first server. Before establishing the channel, the terminal device can use TLS (Transport Layer Security) or other security protocols to encrypt and authenticate the communication connection to ensure the security and reliability of data transmission. On each channel, the terminal device can set different QoS (Quality of Service) levels to control the quality and reliability of information transmission. The terminal device can use different data transmission topics to distinguish different data fragments to ensure the orderliness and reliability of data transmission. The terminal device can also control the order of receiving data fragments through different transmission strategies to ensure the integrity and correctness of the data.

[0117] like Figure 3 As shown, the channels between the terminal device and the first server include the first channel, the second channel and the third channel. Among them, the first channel is the main channel, which is used to transmit the data required for the firmware upgrade, such as data fragmentation, etc.; the second channel is used to transmit device status information and heartbeat packets, and the second channel can maintain a long-term connection to maintain the stability of the communication connection; the third channel is used to transmit log information, etc. By establishing multiple channels, the firmware upgrade and device status information can be processed separately, improving the efficiency and stability of the firmware upgrade, and at the same time, log information can be easily collected for developers to debug and optimize.

[0118] In the embodiment of the present application, multiple first channels can be established between the first server and a single terminal device to transmit multiple data slices, such as Figure 3 In actual application, multiple first channels may be established between the first server and multiple terminal devices. For example, a first channel may be established between the first server and each terminal device to transmit the data slices required by each terminal device.

[0119] Taking a single terminal device as an example, when multiple first channels are established between the terminal device and the first server, in order to avoid all data fragments being sent to the same first channel, a load balancing algorithm can be added to evenly distribute the data fragments to each first channel. Optionally, the load balancing algorithm includes but is not limited to: a polling algorithm, a random algorithm, a weighted polling algorithm, a weighted random algorithm, etc.

[0120] After the terminal device reassembles multiple data fragments into a firmware data packet, it can verify the device status after the firmware upgrade. For example, after the firmware upgrade is completed, the terminal device needs to perform a self-check on the upgraded terminal device to check whether the upgraded terminal device meets the upgrade requirements and specifications; or, the terminal device can compare and check the device status before and after the upgrade to ensure that the upgraded device functions and performance meet the requirements; or, the terminal device can compare and check the device data before and after the upgrade to ensure the integrity and correctness of the upgraded device data.
