Monitoring system, monitoring method, and program

A monitoring system comprising:

• a receiver configured to receive information which defines a living area of a watched person;
• a memory configured to store computer-executable instructions;
• and
• a processor in communication with the memory and configured to execute the computer-executable instructions to at least implement:
• a living area determination unit configured to determine the living area of the watched person based on the information received by the receiver;
• an information accumulation unit configured to accumulate position information of a first terminal carried by the watched person, the position information being determined based on information uploaded from the first terminal, wherein the information comprises a weighted combination of geolocation positioning information, wireless network information, and base station information;
• a determination unit configured to determine a positional relationship between a position of the first terminal, which is determined based on the position information of the first terminal, and the living area;
• and
• a notification unit configured to notify a second terminal, which is designated in advance, of a determination result by the determination unit.

A monitoring method executed by a processor, the monitoring method comprising:

• of accumulating, by the processor, position information of a first terminal carried by a watched person in a storage device, the position information being determined based on information uploaded from the first terminal, wherein the information comprises a weighted combination of geolocation positioning information, wireless network information, and base station information;
• determining, by the processor and without user input, a living area of the watched person, based on position information accumulated in a predetermined period among pieces of the position information accumulated in the storage device, wherein the predetermined period is set by a second terminal, and wherein the second terminal is separate from the first terminal;
• determining, by the processor, a positional relationship between a position of the first terminal, which is determined based on the position information of the first terminal, and the living area;
• and
• notifying, by the processor, the second terminal, which is designated in advance, of a result of the determining of the positional relationship.

A non-transitory computer-readable medium comprising computer-executable instructions, which when executed by a processor of a monitoring system, causes the monitoring system to:

• accumulate position information of a first terminal carried by a watched person in a storage device, the position information being determined based on information uploaded from the first terminal, wherein the information comprises a weighted combination of geolocation positioning information, wireless network information, and base station information;
• determine, without user input, a living area of the watched person based on position information accumulated in a predetermined period among pieces of the position information accumulated in the storage device, wherein the predetermined period is set by a second terminal, and wherein the second terminal is separate from the first terminal;
• determine a positional relationship between a position of the first terminal, which is determined based on the position information of the first terminal, and the living area;
• and
• notify the second terminal, which is designated in advance, of a result of the determining of the positional relationship.
