Abstract

A mobile communication apparatus includes an abnormality detecting unit that detects whether or not there is an abnormality on a route; and a communication unit. When second abnormality detection information which differs from first abnormality detection information that indicates the detected abnormality has been received, it is determined that whether or not the abnormalities indicated by both information items coincide with each other. If it is determined that both abnormalities coincide with each other, then whether or not it is necessary to transmit the first abnormality detection information is determined based on a positional relationship between a position of the own apparatus and an occurrence point of the abnormality at the time when the abnormality indicated by the second abnormality detection information was detected.

Claims

1. A mobile communication apparatus comprising:

an abnormality detecting unit that detects whether or not there is an abnormality on a route; and

a communication unit that includes a determination unit, wherein if the determination unit determines that transmission is necessary, the communication unit transmits first abnormality detection information which indicates the abnormality detected by the abnormality detecting unit,

wherein when the determination unit has received second abnormality detection information which differs from the first abnormality detection information, the determination unit determines whether or not an abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit; and

if it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, the determination unit determines whether or not it is necessary to transmit the first abnormality detection information in accordance with a positional relationship between a position of the own apparatus and an occurrence point of the abnormality at the time when the abnormality indicated by the second abnormality detection information was detected.

2. The mobile communication apparatus in accordance with claim 1, wherein when it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, if a distance between the own apparatus and the occurrence point of the abnormality at the time when the abnormality indicated by the second abnormality detection information was detected is greater than or equal to a predetermined threshold, then the determination unit determines that it is necessary to transmit the first abnormality detection information.

3. The mobile communication apparatus in accordance with claim 1, wherein when it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, if the communication unit received the second abnormality detection information via radio multi-hop communication and the number of hops at the time when the second abnormality detection information was received is greater than or equal to a predetermined threshold, then the determination unit determines that it is necessary to transmit the first abnormality detection information.

4. The mobile communication apparatus in accordance with claim 1, wherein when it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, if a time elapsing between when the abnormality indicated by the second abnormality detection information was detected and when the abnormality has been detected by the abnormality detecting unit is longer than or equal to a predetermined value, then the determination unit determines that it is necessary to transmit the first abnormality detection information.

5. The mobile communication apparatus in accordance with claim 1, wherein if it is determined by the determination unit that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, then the communication unit transmits information which indicates the number of times of information transmission about the abnormality and is associated with the first abnormality detection information.

8. The mobile communication apparatus in accordance with claim 2, wherein if it is determined by the determination unit that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, then the communication unit transmits information which indicates the number of times of information transmission about the abnormality and is associated with the first abnormality detection information.

9. The mobile communication apparatus in accordance with claim 3, wherein if it is determined by the determination unit that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, then the communication unit transmits information which indicates the number of times of information transmission about the abnormality and is associated with the first abnormality detection information.

10. The mobile communication apparatus in accordance with claim 4, wherein if it is determined by the determination unit that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, then the communication unit transmits information which indicates the number of times of information transmission about the abnormality and is associated with the first abnormality detection information.

6. A mobile communication method comprising:

a step, executed by an abnormality detecting unit, that detects whether or not there is an abnormality on a route;

a step executed when a second abnormality detection information, which differs from a first abnormality detection information that indicates the abnormality detected by the abnormality detecting unit, has been detected, wherein the step determines whether or not an abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit;

a step executed if it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting unit, wherein the step determines whether or not it is necessary to transmit the first abnormality detection information in accordance with a positional relationship between the own position and an occurrence point of the abnormality at the time when the abnormality indicated by the second abnormality detection information was detected; and

a step executed if it is determined in the necessity determination that it is necessary to transmit the first abnormality detection information, wherein the step transmits the first abnormality detection information that indicates the abnormality detected by the abnormality detecting unit.

7. A program that makes a computer execute:

a step, executed by an abnormality detecting device, that detects whether or not there is an abnormality on a route;

a step executed when a second abnormality detection information, which differs from a first abnormality detection information that indicates the abnormality detected by the abnormality detecting device, has been detected, wherein the step determines whether or not an abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting device;

a step executed if it is determined that the abnormality indicated by the second abnormality detection information coincides with the abnormality detected by the abnormality detecting device, wherein the step determines whether or not it is necessary to transmit the first abnormality detection information in accordance with a positional relationship between the own position and an occurrence point of the abnormality at the time when the abnormality indicated by the second abnormality detection information was detected; and

a step executed if it is determined in the necessity determination that it is necessary to transmit the first abnormality detection information, wherein the step transmits the first abnormality detection information that indicates the abnormality detected by the abnormality detecting device.
