Communication device management device, system, method, and non-transitory computer-readable recording medium

A communication device management method comprising:

• detecting a change in possibility/impossibility of communication with a communication device, based on a response from the communication device to a confirmation signal to be transmitted at every predetermined time;
• and
• performing, when a restriction is imposed on a predetermined function of the communication device in which the communication possibility/impossibility is changed from impossible to possible, the restriction after canceling the restriction of the communication device, and performing, when the restriction of the communication device is not imposed, the restriction of the communication device.

A non-transitory computer-readable recording medium recording a communication device management program causing a computer to achieve:

• detecting a change in possibility/impossibility of communication with a communication device, based on a response from the communication device to a confirmation signal to be transmitted at every predetermined time;
• and
• performing, when a restriction is imposed on a predetermined function of the communication device in which the communication possibility/impossibility is changed from impossible to possible, the restriction after canceling the restriction of the communication device, and performing, when the restriction of the communication device is not imposed, the restriction of the communication device.
