Distribution device, distribution method, and terminal device
First Claim
1. A distribution device comprising a processor configured to:
- receive location information and a scheduled path, which starts from a first coverage region in which communication is possible and reaches a second coverage region in which communication is possible by way of an out-of-coverage region in which communication is impossible, from a first terminal device possessed by a user;
when the location information and the scheduled path is received, calculate an expected time within which the user arrives to the second coverage region from the first coverage region by way of the out-of-coverage region;
correct the expected time based on a user property including one of;
ability, physical characteristics, and material possessions of the user; and
distribute an alert to a second terminal device when the location information of the second coverage region is not received from the first terminal device within the corrected expected time.

Abstract
A distribution device according to the present application includes a receiving unit, a calculation unit, and a distribution unit. The receiving unit receives location information from a terminal device owned by a user. The calculation unit calculates, once the receiving unit receives the location information, an expected time within which the user arrives from a first coverage region in which communication is possible by way of an out-of-coverage region in which communication is impossible to a second coverage region. The distribution unit distributes an alert to a predetermined distribution destination if the location information of the second coverage region is not received from the terminal device within the expected time calculated by the calculation unit.

13. A distribution method comprising, by a distribution device:
-
receiving location information and a scheduled path, which starts from a first coverage region in which communication is possible and reaches a second coverage region in which communication is possible by way of an out-of-coverage region in which communication is impossible, from a first terminal device possessed by a user; calculating, when the location information is received, an expected time within which the user arrives to the second coverage region from the first coverage region by way of the out-of-coverage region; correcting the expected time based on a user property including one of;
ability, physical characteristics, and material possessions of the user; anddistributing an alert to a second terminal device when the location information of the second coverage region is not received from the first terminal device within the corrected expected time. - View Dependent Claims (14)

15. A first terminal device comprising:
-
a locator configured to acquire location information about a present location; and a transmitter configured to transmit the acquired location information to a distribution device, the distribution device including a processor configured to; receive the location information and a scheduled path, which starts from a first coverage region in which communication is possible and reaches a second coverage region in which communication is possible by way of an out-of-coverage region in which communication is impossible; calculate, when the location information is received, an expected time within which a user arrives to the second coverage region from the first coverage region by way of the out-of-coverage region; correct the expected time based on a user property including one of;
ability, physical characteristics, and material possessions of the user; anddistribute an alert to a second terminal device when the location information of the second coverage region is not received from the first terminal device within the corrected expected time.
