[0042] To address the cumbersome technical issues associated with firmware upgrades for private network terminals in existing technologies, this application provides a firmware upgrade device for private network terminals that simplifies the firmware upgrade process.

[0043] Figure 1a This is a flowchart illustrating a firmware upgrade method for a private network terminal provided in an embodiment of this application. In one embodiment, the method is applied to a private network terminal, which includes a public network module and a private network module. The method includes:

[0044] S1. Receive firmware packages from remote servers via the public network module.

[0045] Private network terminals are communication devices that use dedicated networks. They are widely used in fields such as emergency rescue, public safety, transportation, and energy and chemical industries.

[0046] Please see Figure 1b The private network terminal includes a public network module and a private network module. The public network module provides access to public networks, while the private network module provides access to dedicated networks. The remote server can be a server located on the public network. Firmware packages are used to upgrade the firmware of the private network terminal. Typically, the bandwidth of a private network is smaller than that of a public network. Therefore, in this embodiment, the public network module receives firmware packages from a remote server via a public network to upgrade the firmware of the private network terminal. The public network can be Wi-Fi or a 4G network. Of course, the public network can also be other public networks, such as 5G or 6G networks. This application does not impose any restrictions on this.

[0047] S2, the public network module sends the firmware package to the private network module.

[0048] It should be noted that the storage of the private network module is isolated from that of the public network module. Therefore, after receiving the firmware package, the public network module sends the firmware package to the private network module.

[0049] S3, the private network module upgrades the firmware of the private network terminal through a firmware package.

[0050] After receiving the firmware package, the private network module writes the firmware package into the corresponding memory to upgrade the firmware of the private network terminal.

[0051] This application provides a method for firmware upgrade of a private network terminal. The method is applied to a private network terminal, which includes a public network module and a private network module. The method includes: receiving a firmware package from a remote server through the public network module, the firmware package being used to upgrade the firmware of the private network terminal; the public network module sending the firmware package to the private network module; and the private network module upgrading the firmware of the private network terminal using the firmware package. Therefore, in this application's technical solution, the public network module receives the firmware package from a remote server and sends the firmware package to the private network module to achieve firmware upgrade of the private network terminal. It eliminates the need to obtain the firmware package via a USB programming cable, thus eliminating the need for maintenance personnel to perform on-site upgrades, effectively simplifying the firmware upgrade process for private network terminals and reducing maintenance costs.

[0052] In one embodiment, the public network module sends a firmware package to the private network module via a serial communication interface. The serial communication interface can be a Serial Peripheral Interface (SPI) or an Inter-Integrated Circuit (I2C) bus. 2 C). Of course, other types of serial communication interfaces can also be used. For example, a Universal Asynchronous Receiver-Transmitter (UART). This application does not limit this.

[0053] In one embodiment, the public network module sends the firmware package to the private network module, including:

[0054] A. Split the firmware package into multiple smaller packages.

[0055] Each packet includes a header, which contains: the total number of packets, the index number of the current packet, the number of bytes in the current packet, and a checksum. Each packet has a unique index number.

[0056] B. Send multiple small packets to the private network module.

[0057] The public network module sends multiple small packets to the private network module in sequence according to the index number of the small packets.

[0058] In one embodiment, the plurality of packets includes a target packet, the target packet includes a checksum, and after sending the plurality of packets to the private network module, the method further includes:

[0059] a. The private network module determines whether the data of the target small packet is abnormal based on the check code.

[0060] The private network module receives the target packet, extracts the checksum from the target packet, and verifies the data of the target packet.

[0061] It should be noted that if the target packet is corrupted or tampered with during data transmission, the data in the target packet will become abnormal.

[0062] If the private network module fails the verification, it notifies the public network module to retransmit the target packet. If the private network module succeeds in the verification, it sends an acknowledgment message to the public network module to inform it that the private network module has successfully received the target packet.

[0063] b. The public network module sends the target packet according to the preset number of retransmissions.

[0064] The preset number of retransmissions was set by the applicant based on experience. Preferably, the preset number of retransmissions is 3. Of course, the preset number of retransmissions can be other positive integers. This application does not impose any restrictions on this.

[0065] If the private network module detects an anomaly in the target packet after verifying it, it will notify the public network module to retransmit the target packet. Upon receiving the retransmission instruction, the public network module will retransmit the target packet.

[0066] If the number of retransmissions of the target packet exceeds the preset number of retransmissions, the firmware upgrade process of the private network terminal will be stopped.

[0067] It should be noted that for each small packet sent from the public network module to the private network module, the packet index number of that small packet is automatically incremented by one. When the public network module successfully sends all the small packets of the firmware package to the private network module, the private network module extracts the payload of each small packet from multiple small packets to upgrade the firmware of the private network terminal. Specifically, the private network terminal startup process writes the payload of each small packet into the corresponding memory. When the payloads of all small packets are successfully written into memory, it indicates that the private network terminal has completed the firmware upgrade.

[0068] In one embodiment, the private network module calculates the firmware package upgrade progress based on the received packet index number and the total number of packets. For example, if the total number of packets is 100 and the received packet index number is 50, then the current firmware package upgrade progress is 50 / 100 = 50%.
