Abstract: A method includes obtaining, by a first terminal, version information of a second terminal, where the version information of the second terminal includes at least a device model and a version number of system software of the second terminal; if the device model of the second terminal is compatible with a device model of the first 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; and if the first terminal determines that system upgrade is to be performed, 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.

Abstract: A fault detection method and a fault detection device for external antennas, where the method comprises generating a first detection signal and transmitting the first detection signal using a main antenna, detecting whether a diversity antenna receives the first detection signal, acquiring a signal strength difference between the signals received by the main antenna and the diversity antenna, respectively, determining that the diversity antenna is faulty when the signal strength difference is not less than a first threshold, determining that the main antenna is faulty when the signal strength difference is not larger than a second threshold, and determining that the main antenna and the diversity antenna are faulty when the signal strength difference is larger than the second threshold and less than the first threshold.
