Abstract

An information management system and the like capable of managing communication processing by an internal system mounted on a mobile apparatus such as a motor vehicle to ensure efficient use of information processing resources for packets distributed from an external system are provided. According to the information management system (100), a first processing section (110) determines necessity/unnecessity of a file for an information processing device (12) mounted on the motor vehicle based on file information about the content of the file distributed or transmitted from an external system (20). If the first processing section (110) determines that the file is necessary for the information processing device (12), a second processing section (120) causes the internal system (10) to execute “relay processing” of the file including collection and accumulation of packets, decoding of the packets to restore the file, and others.

Claims

1. A system for processing packets of a file on a mobile apparatus, the system comprising:

an internal system mounted on the mobile apparatus and configured to receive destination information for designating an information processing device as a destination of the file, version information for identifying the version of the file, and a file identifier for identification of the file from an external system;

an information processing device mounted on the mobile apparatus and configured to receive the file from the internal system via an output circuit; and

an information management system integrated with the internal system and the information processing device on the mobile apparatus for managing relay processing including collection and accumulation of the packets distributed or broadcast from the external system by the internal system, decoding of the accumulated packets to restore the file, and outputting of the file to the information processing device, the information management system comprising;

a first processing section configured to determine the necessity/unnecessity of the file for the information processing device as a destination of the file based on the destination information and the version information; and

a second processing section configured to control the internal system to execute the relay processing of collecting, accumulating, decoding, and outputting the file having the file identifier on the condition that it is determined by the first processing section that the file is necessary for the information processing device.

2. The system according to claim 1, wherein the first processing section outputs the destination and version information to the information processing device, and determines necessity/unnecessity of the file for the information processing device in accordance with a type or presence/absence of a response signal received from the information processing device.

3. The system according to claim 2, wherein the response signal from the information processing device is generated based on the version information of the file.

4. The system according to claim 2, wherein the response signal from the information processing device is generated based on the destination information.

5. The system according to claim 1, wherein the second processing section is further configured to control the internal system to stop accumulation of the packets constituting the file when the first processing section determines that the file is unnecessary for the information processing device.

6. The system according to claim 5, wherein the second processing section is further configured to control the internal system to remove the stoppage of the accumulation of the packets constituting the file when the first processing section subsequently determines that the file is necessary for the information processing device.

7. The system according to claim 5, wherein the second processing section is further configured to control the internal system to erase or discard part or all of the accumulated packets when the time during which the accumulation of the packets is stopped has exceeded a threshold value or a current time has passed an effective period of the packets or the file.

8. The system according to claim 1, wherein the internal system is configured to receive from the external system a degree of necessity of the file;

wherein the first processing section is further configured to recognize the degree of necessity of the file, and

wherein when the amount of packets accumulated by the internal system has reached an upper limit, the second processing section is further configured to control the internal system to preferentially erase or discard the packets constituting the file from the accumulated packets if the file is recognized by the first processing section to have a lower degree of necessity than files associated with other accumulated packets.

9. The system according to claim 1, wherein the mobile apparatus is a motor vehicle.

10. The system according to claim 1 further comprising a computer mounted in the mobile apparatus and an information management program for causing the computer to function as the information management system.

11. The system according to claim 10, wherein part or all of the information management program is distributed or broadcast to the computer.
