Abstract
A communication device includes a memory and a processor coupled to the memory and configured to, when a first vibration is detected in the communication device, set a certain state that protects information stored in the memory, and cancel the certain state based on receiving from another communication device a notification indicating that the other communication device detected a second vibration.
Claims12
A communication device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- when a first vibration is detected in the communication device, set a certain state that protects information stored in the memory, and
- cancel the certain state based on receiving from another communication device a notification indicating that the other communication device detected a second vibration.
2 more elements
A system comprising:
- a plurality of communication devices included in a communication network;
- and
- a management device that manages the plurality of communication devices,
- wherein the management device includes a first processor configured to:
- when occurrence of an earthquake is detected, generate a control command that controls a state of certain communication devices from among the plurality of communication devices, the certain communication devices being in an area where the earthquake occurred, and
- output the control command to the certain communication devices, and
- wherein the plurality of communication devices respectively include a memory and a second processor configured to:
- when a first vibration is detected in the communication device, set a certain state that protects information stored in the memory, and
- cancel the certain state in accordance with receiving of the control command.
6 more elements
A control method executed by a communication device, comprising:
- when a first vibration is detected in the communication device, setting a certain state that protects information stored in a memory of the communication device;
- and
- canceling, by a processor of the communication device, the certain state based on receiving from another communication device a notification indicating that the other communication device detected a second vibration.
