Specifically, the terminal determines whether to upgrade the software version according to the upgrade control information and the local terminal version information. The step may specifically include the steps of:
if the hardware model in the terminal version number is judged to be the same as the hardware model in the terminal version information, respectively comparing the main version number and the sub-version number in the terminal version number with the main version number and the sub-version number in the terminal version information; if the hardware model in the terminal version number is different from the hardware model in the terminal version information, subsequent method steps do not need to be executed.
And determining whether to enter an upgrading sub-band corresponding to the upgrading sub-band number according to the comparison result and the upgrading control word, and upgrading by adopting an upgrading mode corresponding to the upgrading control word. The step may specifically include the steps of:
and if the upgrade control word is judged to be the upgrade control word only upgraded when the major version number changes, and the comparison result comprises that the major version number in the terminal version number is different from the major version number in the terminal version information, determining to enter an upgrade sub-band corresponding to the upgrade sub-band number, and upgrading the major version number.
