Abstract

A control device mountable on a movable apparatus includes a position information acquisition unit configured to acquire position information of the movable apparatus, a position information notification unit configured to notify an information processing device of the position information acquired by the position information acquisition unit, a distribution connection area acquisition unit configured to acquire, from the information processing device, distribution connection area information corresponding to the position information notified by the position information notification unit, a transmission unit configured to transmit any one of a subscription registration request and a subscription cancellation request to the information processing device on the basis of an area indicated by the distribution connection area information acquired by the distribution connection area acquisition unit and a position indicated by the position information acquired by the position information acquisition unit, and a reception unit configured to receive a published message transmitted from the information processing device in response to the request transmitted by the transmission unit.

First claim

What is claimed is:

1. A control method for a control device mounted on a movable apparatus, comprising:
acquiring position information of the movable apparatus;
notifying an information processing device of the position information acquired in the position information acquisition;
acquiring, from the information processing device, distribution connection area information corresponding to the position information notified in the position information notification;
transmitting any one of a subscription registration request and a subscription cancellation request to the information processing device on the basis of an area indicated by the distribution connection area information acquired in the distribution connection area acquisition and a position indicated by the position information acquired in the position information acquisition;
receiving a published message transmitted from the information processing device in response to the request transmitted in the transmission; and
determining an area to connect to the information processing device based on the distribution connection area information,
wherein the distribution connection area information is information indicating a connection area of a distribution range corresponding to a communication area of a base station, and the distribution connection area corresponds to an area provided, wherein the movable apparatus receives distribution of information before reaching the distribution range in consideration of delays including a delay in communication between the control device and the base station and a processing time of the control device.

2. A control device mountable on a movable apparatus, comprising at least one processor or circuit configured to function as:
a position information acquisition unit configured to acquire position information of the movable apparatus;
a position information notification unit configured to notify an information processing device of the position information acquired by the position information acquisition unit;
a distribution connection area acquisition unit configured to acquire, from the information processing device, distribution connection area information corresponding to the position information notified by the position information notification unit;
a transmission unit configured to transmit any one of a subscription registration request and a subscription cancellation request to the information processing device on the basis of an area indicated by the distribution connection area information acquired by the distribution connection area acquisition unit and a position indicated by the position information acquired by the position information acquisition unit;
a reception unit configured to receive a published message transmitted from the information processing device in response to the request transmitted by the transmission unit; and
a determination unit configured to determine an area to connect to the information processing device based on the distribution connection area information,
wherein the distribution connection area information is information indicating a connection area of a distribution range corresponding to a communication area of a base station, and the distribution connection area corresponds to an area provided, wherein the movable apparatus receives distribution of information before reaching the distribution range in consideration of delays including a delay in communication between the control device and the base station and a processing time of the control device.

3. The control device according to claim 2 , wherein the at least one processor or circuit is further configured to function as:
a comparison unit configured to compare the area indicated by the distribution connection area information acquired by the distribution connection area acquisition unit with the position indicated by the position information acquired by the position information acquisition unit,
wherein the transmission unit transmits any one of the subscription registration request and the subscription cancellation request to the information processing device according to a comparison result of the comparison unit.

4. The control device according to claim 2 , wherein the distribution connection area information is calculated based on a boundary of distribution range information indicating an area for distributing the published message.

5. The control device according to claim 2 , wherein the transmission unit transmits the subscription registration request and the subscription cancellation request if the position indicated by the position information enters or exits the area indicated by the distribution connection area information.

6. The control device according to claim 2 , wherein the position information of the movable apparatus acquired by the position information acquisition unit is position information of a current position of the movable apparatus or position information of a destination of the movable apparatus.

7. The control device according to claim 2 , wherein the at least one processor or circuit is further configured to function as:
a receiving unit configured to receive information regarding topics;
wherein the transmission unit is configured to transmit one of a subscription registration request and a subscription cancellation request regarding the topics to the information processing device on the basis of the area indicated by the distribution connection area information acquired by the distribution connection area acquisition unit and a position indicated by the position information acquired by the position information acquisition unit.

8. The control device according to claim 2 , wherein the at least one processor or circuit is further configured to function as:
a communication method providing unit configured to provide information relating to the communication method to the information processing device.

9. A movable apparatus comprising at least one processor or circuit configured to function as:
a position information acquisition unit configured to acquire position information of the movable apparatus;
a position information notification unit configured to notify an information processing device of the position information acquired by the position information acquisition unit;
a distribution connection area acquisition unit configured to acquire, from the information processing device, distribution connection area information corresponding to the position information notified by the position information notification unit;
a transmission unit configured to transmit any one of a subscription registration request and a subscription cancellation request to the information processing device on the basis of an area indicated by the distribution connection area information acquired by the distribution connection area acquisition unit and a position indicated by the position information acquired by the position information acquisition unit;
a reception unit configured to receive a published message transmitted from the information processing device in response to the request transmitted by the transmission unit;
a moving unit configured to move the movable apparatus; and
a determination unit configured to determine an area to connect to the information processing device based on the distribution connection area information,
wherein the distribution connection area information is information indicating a connection area of a distribution range corresponding to a communication area of a base station, and the distribution connection area corresponds to an area provided, wherein the movable apparatus receives distribution of information before reaching the distribution range in consideration of delays includin
