Abstract

A wireless communication apparatus mounted on a mobile body includes a transmitter and a receiver. The transmitter is configured to transmit position information indicating a position to which the mobile body is scheduled to move, to a server apparatus. The receiver is configured to receive communication quality information indicating a communication quality corresponding to the position, from the server apparatus. The transmitter is configured to transmit the date at a communication position specified based on the communication quality information.

First claim

What is claimed is:

1 . A wireless communication apparatus mounted on a mobile body, comprising:
a transmitter configured to transmit position information indicating a position to which the mobile body is scheduled to move, to a server apparatus that manages a wireless communication infrastructure apparatus; a receiver configured to receive communication quality information indicating a communication quality corresponding to the position, from the server apparatus; and a position specifying unit configured to specify a communication position to transmit a data, based on the communication quality information, wherein the transmitter is configured to transmit the data at the communication position.

2 . The wireless communication apparatus according to claim 1 , wherein:
the transmitter is configured to further transmit time information indicating a clock time when the mobile body is scheduled to reach the position, to the server apparatus; and the receiver is configured to receive the communication quality information indicating the communication quality corresponding to the position and the clock time.

3 . The wireless communication apparatus according to claim 1 , wherein:
the transmitter is configured to further transmit data amount information indicating a data amount of the data, to the server apparatus; and the receiver is configured to receive the communication quality information indicating the communication quality when transmitting the data having the data amount.

4 . The wireless communication apparatus according to claim 1 , further comprising:
a storage configured to store the data until the data is transmitted from the transmitter; and a data processing unit configured to adjust a compression rate of the data stored in the storage based on a period of time until the mobile body reaches the communication position.

5 . The wireless communication apparatus according to claim 1 , further comprising:
a storage configured to store in association with each other (i) the data and (ii) information indicating a priority of the data, until the data is transmitted from the transmitter; and a data processing unit configured to delete the data stored in the storage in an order from the data having the priority being lowest based on a period of time until the mobile body reaches the communication position.

6 . The wireless communication apparatus according to claim 1 ,
wherein the wireless communication apparatus communicates using a first communication service that communicates at the communication position or using a second communication service that communicates regardless of a position of the mobile body, wherein the wireless communication apparatus further comprises: a storage configured to store in association with each other (i) the data and (ii) information indicating a priority of the data; and a determining unit configured to determine whether to transmit the data using the first communication service or the second communication service based on the priority of the data, wherein based on a determination result by the determining unit, in response to the priority of the data being not higher than a predetermined priority, the transmitter is configured to transmit the data by using the first communication service, and in response to the priority of the data being higher than the predetermined priority, the transmitter is configured to transmit the data by using the second communication service.

7 . The wireless communication apparatus according to claim 6 , wherein:
the data is vehicle data acquired by a sensor mounted on a vehicle being the mobile body; the receiver is configured to further receive user data, which is data used by a user of the vehicle, using the second communication service; and in response to the priority of the data being higher than the predetermined priority and a data amount of the user data being smaller than a predetermined data amount, the determining unit is configured to determine that the data is transmitted using the second communication service.

8 . The wireless communication apparatus according to claim 7 , wherein:
the data amount of the user data is predicted as the data amount of the user data that the receiver receives in future.

9 . A computer-implemented communication control method executed by a computer for a wireless communication apparatus mounted on a mobile body, the method comprising:
transmitting position information indicating a position to which the mobile body is scheduled to move, to a server apparatus that manages a wireless communication infrastructure apparatus; receiving communication quality information indicating a communication quality corresponding to the position, from the server apparatus; specifying a communication position to transmit a data, based on the communication quality information; and transmitting the data at the communication position.

10 . A non-transitory computer-readable storage medium storing a communication control program comprising instructions configured to, when executed by a computer, cause the computer to perform the communication control method according to claim 9 .

11 . A server apparatus that communicates with the wireless communication apparatus according to claim 1 ,
the server apparatus comprising: a receiver configured to receive position information transmitted from the wireless communication apparatus; a communication quality information generating unit configured to generate communication quality information indicating a communication quality corresponding to a position indicated by the position information; and a transmitter configured to transmit the communication quality information to the wireless communication apparatus.

12 . A computer-implemented communication quality providing method executed by a computer for a server apparatus communicating with the wireless communication apparatus according to claim 1 ,
the communication quality providing method comprising: receiving position information transmitted from the wireless communication apparatus; generating communication quality information indicating a communication quality corresponding to a position indicated by the position information; and transmitting the communication quality information to the wireless communication apparatus.

13 . A wireless communication apparatus mounted on a mobile body, comprising:
a transmitter configured to transmit position information indicating a position to which the mobile body is scheduled to move, to a server apparatus that manages a wireless communication infrastructure apparatus; a receiver configured to receive communication quality information indicating a communication quality corresponding to the position, from the server apparatus; and a controller circuit coupled with the transmitter and the receiver, the controller circuit being configured to specify a communication position to transmit a data, based on the communication quality information, wherein the transmitter is configured to transmit the data at the communication position.

14 . The server apparatus according to claim 11 , further comprising:
a controller circuit coupled with the transmitter and the receiver, the controller circuit being configured to implement the communication quality information generating unit.
