Abstract
To enable reporting user status more precisely and over a wide range, the present invention includes an information terminal PC1 having a generating device, a mobile terminal M having a transmitting device, and an information terminal PC2 having a receiving device. The information terminal PC1 and the mobile terminal M can communicate directly wirelessly or through a wire. The mobile terminal M and the information terminal PC2 can communicate in real time via status notification devices. The information terminal PC1 reports the user status it detected to a mobile terminal M that is in a communicable area. The mobile terminal M sends the user status to the information terminal PC2 via the status notification device if the user status it received is the status of the user that has been stored therein in advance. If the user carries a mobile terminal M while he is on the trip, the status can be reported from the information terminal PC1 to the information terminal PC2 regardless of whether the information terminal PC1 belongs to a network or whether the information terminal PC1 has a certain status notification device.
