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

a first processing section to determine necessity/unnecessity of the file for the information processing device based on file information about a content of the file distributed or broadcast from the external system; and

a second processing section to cause the internal system to execute the relay processing of the file on the condition that it is determined by the first processing section that the file is necessary for the information processing device.

2. The information management system according to claim 1, wherein the first processing section outputs the file 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 from the information processing device to the file information.

3. The information management system according to claim 1, wherein the first processing section determines necessity/unnecessity of the file for the information processing device in accordance with a type or presence/absence of a response signal from the information processing device to the file information for identification of an effective period or version of the file.

4. The information management system according to claim 1, wherein the first processing section determines necessity/unnecessity of the file for the information processing device based on a result of communication with the information processing device identified by destination information distributed from the external system.

5. The information management system according to claim 1, wherein the second processing section causes the internal system to stop accumulation of the packets constituting the file on the condition that it is determined by the first processing section that the file is unnecessary for the information processing device.

6. The information management system according to claim 5, wherein after the second processing section causes the internal system to stop the accumulation of the packets constituting the file, on the condition that it is determined by the first processing section that the file is necessary for the information processing device, the second processing section causes the internal system to remove the stoppage of the accumulation of the packets.

7. The information management system according to claim 1, wherein the second processing section determines whether the time during which the accumulation of the packets is stopped has exceeded a threshold value, or whether the current time has passed an effective period of the packets or the file, and on the condition that it is determined that the time during which the accumulation of the packets is stopped has exceeded the threshold value or that the current time has passed the effective period of the packets or the file, the second processing section causes the internal system to erase or discard part or all of the accumulated packets.

8. The information management system according to claim 1, wherein

the first processing section recognizes a degree of necessity of each file for the information processing device based on the file information, and

on the condition that the accumulated amount of the packets by the internal system has reached an upper limit, the second processing section causes the internal system to preferentially erase or discard the packets constituting the file recognized to have a lower degree of necessity by the first processing section from among the accumulated packets.

9. A motor vehicle as a mobile apparatus having mounted thereon an information management system for managing relay processing including collection and accumulation of packets distributed or broadcast from an external system by an internal system mounted on the mobile apparatus, decoding of the accumulated packets to restore a file, and outputting of the file to an information processing device mounted on the mobile apparatus, the information management system comprising:

a first processing section to determine necessity/unnecessity of the file for the information processing device based on file information about a content of the file distributed or broadcast from the external system; and

a second processing section to cause the internal system to execute the relay processing of the file on the condition that it is determined by the first processing section that the file is necessary for the information processing device.

10. An information management program for causing a computer mounted in a mobile apparatus to function as an information management system for managing relay processing including collection and accumulation of packets distributed or broadcast from an external system by an internal system mounted on the mobile apparatus, decoding of the accumulated packets to restore a file, and outputting of the file to an information processing device mounted on the mobile apparatus, the information management system comprising:

a first processing section to determine necessity/unnecessity of the file for the information processing device based on file information about a content of the file distributed or broadcast from the external system; and

a second processing section to cause the internal system to execute the relay processing of the file on the condition that it is determined by the first processing section that the file is necessary for the information processing device.

11. An establishment system for establishing a computer mounted in a mobile apparatus as an information management system by distributing or broadcasting part or all of an information management program to the computer, the information management system

managing relay processing including collection and accumulation of packets distributed or broadcast from an external system by an internal system mounted on the mobile apparatus, decoding of the accumulated packets to restore a file, and outputting of the file to an information processing device mounted on the mobile apparatus, and

including:

a first processing section to determine necessity/unnecessity of the file for the information processing device based on file information about a content of the file distributed or broadcast from the external system; and

a second processing section to cause the internal system to execute the relay processing of the file on the condition that it is determined by the first processing section that the file is necessary for the information processing device.

12. An external system distributing or broadcasting packets to be collected and accumulated by an internal system mounted on a mobile apparatus,

the external system further distributing or broadcasting file information about a content of a file to cause an information management system, which manages relay processing including decoding of the packets accumulated by the internal system to restore a file, and outputting of the file to an information processing device mounted on the mobile apparatus, to determine necessity/unnecessity of the file for the information processing device based on the file information, and to cause the information management system to allow the internal system to execute the relay processing of the file in response to a determination result that the file is necessary.
