Abstract

An extracting unit detects movement from a first area to a second area, the first area and the second area defined as areas having different priorities. When the extracting unit detects the movement, this changes a communication process defined in the first area to the communication process defined in the second area. A notifying unit notifies that the area changed when the movement is detected. Herein, the priority of the first area and the priority of the second area are defined according to importance of a signal, which should be broadcasted from a processing unit.

Claims

1. A radio apparatus, comprising:

a detecting unit configured to detect movement from a first area to a second area, the first area and the second area defined as areas having different priorities;

a communicating unit configured to change a communication process defined in the first area to a communication process defined in the second area if the detecting unit detects the movement; and

a notifying unit configured to notify that the area changed if the detecting unit detects the movement.

2. The radio apparatus according to claim 1, wherein

a priority of the first area and the priority of the second area are defined according to importance of a signal, which should be broadcasted from the communicating unit.

3. The radio apparatus according to claim 1, wherein

the communicating unit is capable of receiving a signal from a base station apparatus and a priority of the first area and the priority of the second area are defined according to a quality of a received signal.

4. The radio apparatus according to claim 1, wherein

the communicating unit is capable of receiving a signal from a base station apparatus and a priority of the first area and the priority of the second area are defined according to a distance from a base station apparatus.

5. The radio apparatus according to claim 1, wherein

the notifying unit notifies that the area changed by changing a mode of notification if the radio apparatus is present in the first area to a mode of notification if the radio apparatus is present in the second area.

6. A radio apparatus, comprising:

a detecting unit configured to detect movement between a first area and a second area, the first area formed around an installed position of a base station apparatus and the second area formed on the outside of the first area relative to the base station apparatus;

a communicating unit configured to change a communication process between the communication process in the first area, which should be performed according to operation timing of the base station apparatus, and a communication process in the second area, which should be performed irrespective of the operation timing of the base station apparatus, if the detecting unit detects the movement; and

a notifying unit configured to notify that the area changed if the detecting unit detects the movement.

7. A radio apparatus, which executes communication with another radio apparatus, comprising:

an estimating unit configured to estimate whether the radio apparatus is present in a vehicle or on the outside of the vehicle; and

a communicating unit configured to execute a transmission process and a reception process if the estimating unit estimates that the radio apparatus is present in the vehicle, wherein

the communicating unit stops at least one of the transmission process and the reception process if the estimating unit estimates that the radio apparatus is present on the outside of the vehicle.

8. The radio apparatus according to claim 7, further comprising:

a connecting unit connected to a power supply terminal provided on the vehicle; and

a battery configured to drive the radio apparatus if the connecting unit is not connected to the power supply terminal, wherein

the estimating unit estimates that the radio apparatus is present on the outside of the vehicle if the radio apparatus is driven by the battery.

9. The radio apparatus according to claim 7, wherein the communicating unit stops the reception process out of the transmission process and the reception process.
