Problems solved by technology
Usually the size of the update file is tens of KB to hundreds of KB. Since the number of Internet of Things terminal devices 30 is large, the load and cost of the OTA server 10 will be greatly increased, and more network resources will be taken up simultaneously. Pay more network traffic costs, and the update efficiency is relatively low

Embodiment Construction
[0040] see figure 2 , Embodiment 1 of the OTA upgrade system for proximity to terminal devices provided in this application includes an OTA server 10 , a gateway 20 and a plurality of terminal devices 30 . The OTA server 10 is used to respond to the update request of the terminal device 30 to inform the terminal device 30 whether there is an update file. The OTA server 10 is also used to respond to the download update request of the terminal device 30, and when none of the adjacent terminal devices of the terminal device 30 has downloaded the update file, it directly sends the update file to the terminal device 30, and when the adjacent terminal device 30 of the terminal device 30 When the update file has been downloaded in the terminal device, the terminal device 30 is instructed to obtain the update file from a nearby terminal device that has downloaded the update file. The gateway 20 is used to forward the communication between the OTA server 10 and the terminal device 30...

The invention discloses an adjacent OTA upgrading system of a terminal device. The adjacent OTA upgrading system comprises an OTA server, a gateway and a plurality of terminal devices. The OTA serveris used for responding to a query update request and a download update request of the terminal device. The gateway is used for realizing communication forwarding between the OTA server and the terminal device. The terminal device sends a query update request to an OTA server and receives the OTA server to inform whether update exists or not, and the terminal device sends an update downloading request to the OTA server, directly acquires the update file from the OTA server when the adjacent terminal device does not download the update file, and acquires the update file from the adjacent terminal device which has downloaded the update file when the adjacent terminal device has downloaded the update file. According to the OTA updating method and device, the terminal device which has downloaded the updating file serves as the updating source of the adjacent terminal device which does not download the updating file, the pressure of the OTA server is relieved, and the OTA updating efficiencyis improved.
Description
technical field [0001] The present application relates to a method for upgrading firmware or software of terminal equipment. Background technique [0002] With the rise of the Internet of Things, the number of Internet of Things terminal devices has exploded. For the purpose of upgrading functions, repairing defects, and patching security vulnerabilities, manufacturers need to update the firmware in IoT terminal devices from time to time. IoT terminal devices are widely distributed geographically, and most of them are left unattended. Generally, OTA (Over The Air) is used to update firmware. OTA update refers to the use of wireless communication technology to transmit firmware to update. The IoT terminal device queries the server for updates through the network. If there is an update, it requests download from the server, and downloads the update package to the internal memory of the IoT terminal device to complete the update. [0003] see figure 1 , in the existing OTA u...
