Terminal device and method for protecting terminal device, and terminal management server

A method of protecting a terminal device comprising one or more processors, the method executed by the one or more processors, the method comprising:

• monitoring, by the terminal device, an operation state of the terminal device to determine whether the terminal device is in a state of a preset condition for terminal protection, the preset condition including subscriber identity module (SIM) separated away from the terminal device;
• accessing, by the terminal device, a terminal management server through an access point in a wireless communication channel other than a mobile communication network, when the terminal device is in a state of the preset condition for terminal protection;
• sending, by the terminal device through the access point in the wireless communication channel other than the mobile communication network, identification information of the terminal device to the accessed terminal management server;
• locking, by the terminal device, the terminal device when a lock command is issued by, and received, through the access point in the wireless communication channel other than the mobile communication network, from, the terminal management server.

A non-transitory computer-readable storage medium storing a terminal managing program to perform a method of protecting a terminal device comprising one or more processors, the method performed by the one or more processors, the method comprising:

• monitoring, by the terminal device, an operation state of the terminal device to determine whether the terminal device is in a state of a preset condition for terminal protection, the preset condition including subscriber identity module (SIM) separated away from the terminal device;
• accessing, by the terminal device, a terminal management server through an access point in a wireless communication channel other than a mobile communication network, when the terminal device is in a state of the preset condition for terminal protection;
• sending, by the terminal device through the access point in the wireless communication channel other than the mobile communication network, identification information of the terminal device to the accessed terminal management server;
• and
• locking, by the terminal device, the terminal device when a lock command is issued by, and received, through the access point in the wireless communication channel other than the mobile communication network, from, the terminal management server.
