Abstract: A location positioning system notifies of a message by a method according to a situation of a subject while grasping a location of the subject to be watched. The system includes a subject terminal carried by the subject, a server, a judgement unit, and a determination unit. The subject terminal transmits identification information for specifying a location of the terminal through a wireless communication and receives a message directed to the subject, and notifies the subject of reception of the message by at least one output method. The server specifies the location of the subject terminal based on the identification information. The judgement unit judges whether the subject is present indoors or outdoors, based on the location of the subject terminal specified by the server and the map information stored in advance. The determination unit determines an output method of notification by the subject terminal according to the judgement result.

Abstract: An emergency communication system, while accurately and reliably detecting a location of an object person, receives contact from the object person and grasps a state of the object person when a matter of emergency has occurred. An object person terminal transmits identification information via short-range wireless communication, acquires location information by a GPS function, and transmits the identification information and the location information to a server. A detection terminal transmits the identification information transmitted from the object person terminal. The server specifies the location of the object person terminal on the basis of the information transmitted from the detection terminal or the identification information and the location information transmitted from the object person terminal.

Abstract: A location information sharing control system enables detection of a location of an object person with precision while suppressing power consumption of a terminal carried by the object person, and enables a related person other than a specific manager to grasp the location of an object person. An object person terminal transmits identification information via short-range wireless communication. A detection terminal transmits the identification information transmitted from the object person terminal to the server. The server, on the basis of information transmitted from the detection terminal, specifies the location of the object person terminal, and manages the information on a location information sharing user who shares the information on the location of the object person terminal, and shares the information on the location of the object person terminal with the location information sharing user set to be able to share the information on the location of the object person terminal.

Abstract: A position specifying system can accurately detect, while reducing a power consumption amount of a carried terminal, a position within a watching area where the target person acts every day and can efficiently detect the position even in an emergency where the target person moves out of the watching area. The terminal transmits, at a first time interval, identification information via short-range wireless communication; acquires, at a second time interval, position information with a GPS function; and transmits the identification information and the position information to a server via long-range wireless communication. A terminal for detection transmits the identification information transmitted from the communicable target person terminal.
