Abstract

The invention discloses an upgrade package download method, device, server, terminal and system. The method includes: controlling the server to monitor whether the OTA domain name resolution is abnormal; when the monitoring result is yes, the control server sends the upgrade to the terminal The download address of the package and the network protocol IP address information of the domain name in the download address; the terminal connects to the OTA server corresponding to the IP address information, and requests to download the upgrade package from the download address; the OTA server downloads the upgrade package sent to the terminal. Utilizing the technical solution provided by the embodiment of the present invention can ensure that the terminal obtains the correct IP address information corresponding to the OTA domain name, and then downloads the required upgrade package.

Description

technical field [0001] The invention relates to the technical field of Internet communication, in particular to an upgrade package download method, device, server, terminal and system. Background technique [0002] OTA (Over-the-Air) technology is a technology for remote management of data and applications through the air interface of mobile communication, and is widely used in downloading and upgrading services. For example, a car with OTA function can upgrade the car ECU (Electronic Control Unit, electronic control unit) online through the Internet to realize the optimization and upgrade of ECU performance. [0003] At present, the upgrade package download processing method utilizing OTA technology may include: the server sends the download address of the upgrade package to the terminal; the terminal queries the domain name resolution server for the IP (Internet Protocol, Internet Protocol) address information of the OTA domain name in the upgrade package download address;...
