Device and system for message processing
First Claim
1. A message processing device in an inter-vehicle network of a plurality of message processing devices located in respective vehicles for transferring messages among the vehicles, each message processing device comprising:
- a message receiving unit for receiving a message having a body including data to be transmitted and a header including a valid time duration, a valid geographical zone, and a flag, the flag being set when the message reaches the valid geographical zone;
a duration determination unit for determining whether or not the message is within the valid time duration when the message receiving unit receives the message;
a zone determination unit for determining whether or not the message processing device is located within the valid geographical zone when the message receiving unit receives the message;
a message transferring unit for transferring the message to at least one other message processing device when the duration determination unit and the zone determination unit give positive results, or when the duration determination unit gives a positive result, the zone determination unit gives a negative result, and the flag is not set; and
an application processing unit for reading out data included in the body to execute predetermined processing based on the data when the duration determination unit and zone determination unit gives positive results, wherein the predetermined processing is other than transferring the message.

Abstract
In a message processing system, a plurality of vehicles or other locations are equipped with message processing devices and transmit and receive a message. The message has a header and a body. The header includes a valid duration and/or a valid zone specified by various methods, and an optional flag set when the message reaches the valid zone. The body includes data to be transmitted and read out for predetermined processing. When receiving the message, the message processing device may transfer the message if the message is within the valid duration and the device is within the valid zone, or if the message is within the duration and the device is not within the valid zone but the flag is not set. When transmitting a message, the message processing device sets the valid duration and/or zone and may include the flag for the message header, and generates the data to be transmitted for the message body.

5. A message processing device in a network of message processing devices, each message processing device comprising:
-
a valid duration setting unit for setting a valid time duration for a message; a zone setting unit for setting a valid geographical zone; an application processing unit for generating data to be transmitted; and a message transmitting unit for transmitting a message having a body including the data generated by the application processing unit and a header including the valid time duration set by the valid duration setting unit, the valid geographical zone set by the zone setting unit, and a flag, the flag being set when the message reaches the valid geographical zone; whereby the valid time duration and valid geographical zone are checked by a message processing device receiving the message to determine whether to transfer the message to at least one other message processing device and execute predetermined processing based on the data in the message body, wherein the predetermined processing is other than transferring the message; the message being transferred when the message is received within the valid time duration and within the valid geographical zone, or when the message is received within the valid time duration and is not received within the valid geographical zone and the flag is not set, and the predetermined processing being executed when the message is received within the valid time duration and within the valid geographical zone. - View Dependent Claims (6, 7, 8, 9)
