The invention discloses a dual-
system OTA parallel upgrading method and
system. The method comprises the steps: enabling a first hardware
system and a second hardware system to enter a
recovery mode at the same time, and then synchronously entering a
verification mode, i.e., enabling the second hardware system to verify a second OTA upgrading
package while the first hardware system verifies a first OTA upgrading
package; after
verification is completed, enabling the second hardware system to generate an installation instruction and send the installation instruction to the first hardware system, wherein the first hardware system and the second hardware system synchronously enter an installation mode, and the second hardware system also installs a second OTA
upgrade package while the first OTA
upgrade package is installed in the first hardware system; when the installation is completed, synchronously restarting the first hardware system and the second hardware system. Therefore, according to the method and the system provided by the embodiment of the invention, OTA parallel upgrading of the dual systems can be realized, the dual systems can simultaneously enter a
verification mode, synchronously enter an installation mode and simultaneously restart, the upgrading efficiency of the dual systems is improved, the upgrading duration cannot be prolonged, and the user experience is improved.
