Abstract

A delivery method between a terminal device and a delivery device, the method includes: causing the terminal device to request a connection to the delivery device, and request the delivery device to update information to be delivered when the terminal device is connected to the delivery device; and causing the delivery device to deliver delivery target information stored in a storage unit, to interrupt delivery of the delivery target information and to switch to connection to the terminal device, when the connection request is made by the terminal device, to authenticate the terminal device, to restart delivery of the delivery target information when an authentication is not obtained in a first predetermined period, and to update the delivery target information stored in the storage unit in response to a request from the terminal device when the authentication is obtained in the first predetermined period.

First claim

What is claimed is:

1 . A delivery system comprising a terminal device and a delivery device, wherein
the terminal device includes:
a connection request unit configured to make a connection request to the delivery device configured to deliver information; and
an update request unit configured to request the delivery device to update information to be delivered when the terminal device is connected to the delivery device,
the delivery device includes
a storage unit configured to store delivery target information;
a delivery unit configured to deliver the delivery target information stored in the storage unit;
a switching unit configured to interrupt delivery by the delivery unit and perform switching to connection to the terminal device, when the connection request is made by the terminal device;
an authentication unit configured to authenticate the terminal device;
a restart control unit configured to cause the delivery unit to restart delivery when an authentication result as a proper terminal by the authentication unit is not obtained in a first predetermined period; and
an update unit configured to update the delivery target information stored in the storage unit in response to a request from the terminal device, when the authentication result as a proper terminal by the authentication unit is obtained in the first predetermined period.

2 . The delivery system according to claim 1 , wherein
if the delivery unit restarts the delivery, the switching unit suspends the switching for a second predetermined period even when the terminal device makes a connection request.

3 . The delivery system according to claim 1 , wherein
the delivery device further includes a notification unit configured to generate a challenge code using internal information of the delivery device and to notify the terminal device of the challenge code, when the switching unit switches to a state to connect to the terminal device, the terminal device further includes an authentication request unit configured to request authentication by sending the delivery device authentication information which is a predetermined code for use in authentication encrypted with the challenge code, and the authentication unit performs authentication by using the authentication information received from the terminal device, the challenge code, and the predetermined code for use in authentication.

4 . The delivery system according to claim 3 , wherein
the notification unit generates a challenge code including management information indicating an operating state that includes at least time information of the delivery device, and notifies the terminal device of the challenge code.

5 . A delivery method to be executed by a terminal device and a delivery device, the method comprising:
causing the terminal device to
make a connection request to the delivery device configured to deliver information, and
request the delivery device to update information to be delivered when the terminal device is connected to the delivery device; and
causing the delivery device to
deliver delivery target information stored in a storage unit,
interrupt delivery of the delivery target information and perform switching to connection to the terminal device, when the connection request is made by the terminal device,
authenticate the terminal device,
restart delivery of the delivery target information when an authentication result as a proper terminal is not obtained in a first predetermined period, and
update the delivery target information stored in the storage unit in response to a request from the terminal device when the authentication result as a proper terminal is obtained in the first predetermined period.

6 . A delivery device, comprising:
a storage unit configured to store delivery target information; a delivery unit configured to deliver the delivery target information stored in the storage unit; a switching unit configured to interrupt delivery by the delivery unit and perform switching to connection to a terminal device, when a connection request is made by the terminal device; an authentication unit configured to authenticate the terminal device at the time of the switching to connection; a restart control unit configured to cause the delivery unit to restart delivery when an authentication result as a proper terminal by the authentication unit is not obtained in a first predetermined period; and an update unit configured to update the delivery target information stored in the storage unit in response to a request from the terminal device, when the authentication result as a proper terminal by the authentication unit is obtained in the first predetermined period.
