Method for Upgrading Terminal System, Terminal, and System

A method for upgrading a terminal system, the method comprising:

• obtaining, by a first terminal, version information of a second terminal, wherein the version information of the second terminal comprises at least a device model and a version number of system software of the second terminal;
• determining, by the first terminal according to the version number of the system software of the second terminal and a version number of system software of the first terminal, whether system upgrade is to be performed on the first terminal when the device model of the second terminal is compatible with a device model of the first terminal;
• obtaining, by the first terminal from the second terminal, system software data indicated by the version number of the system software of the second terminal when the first terminal determines that system upgrade is to be performed;
• and
• upgrading the first terminal according to the obtained system software data.

A terminal comprising:

• a communication interface;
• a memory;
• and
• a processor coupled to the communication interface and the memory, wherein the processor is configured to:
• obtain version information of a second terminal via the communications interface, wherein the version information of the second terminal comprises at least a device model and a version number of system software of the second terminal;
• determine, according to the version number of the system software of the second terminal and a version number of system software of the first terminal, whether system upgrade is to be performed on the first terminal, when the device model of the second terminal is compatible with a device model of a first terminal;
• obtain, from the second terminal via the communications interface, system software data indicated by the version number of the system software of the second terminal when the first terminal determines that system upgrade is to be performed;
• and
• complete the system upgrade on the first terminal according to the system software data, wherein the memory is configured to store the system software data of the second terminal.

An upgrade system comprising:

• a terminal comprising:
• a communication interface;
• a memory;
• and
• a processor coupled to the communication interface and the memory, wherein the processor is configured to:
• obtain version information of a second terminal via the communications interface, wherein the version information of the second terminal comprises at least a device model and a version number of system software of the second terminal;
• determine, according to the version number of the system software of the second terminal and a version number of system software of the first terminal, whether system upgrade is to be performed on the first terminal, when the device model of the second terminal is compatible with a device model of a first terminal;
• and
• obtain, from the second terminal via the communications interface, system software data indicated by the version number of the system software of the second terminal when the first terminal determines that system upgrade is to be performed;
• and
• complete the system upgrade on the first terminal according to the system software data, wherein the memory is configured to store the system software data of the second terminal;
• and
• a second terminal connected to the terminal.
