The example cited here is that the user terminal selects the upgrade package to be downloaded. In fact, the network management device side can also directly select an upgrade package higher than the current version of the chip operating system of the SIM card for the SIM card of the terminal device; such as: The terminal device uses the identification information of the SIM card and the version number of the chip operating system of the SIM card to generate a chip operating system upgrade request and send it to the network management device; so that the network management device selects a corresponding upgrade according to the identification information of the SIM card package list information, and then select an upgrade package higher than the chip operating system version number from the upgrade package list information according to the chip operating system version number.
