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 for executing 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 operate a transmission processing unit for executing a transmission process to transmit a packet signal including a positional information of the radio apparatus and operate a reception processing unit for executing a reception process to receive a packet including a positional information of the another radio apparatus when the estimating unit estimates that the radio apparatus is present in the vehicle, wherein

the communicating unit stops one of the transmission processing unit and the reception processing unit and causes the other to continue to operate when the estimating unit estimates that the radio apparatus is present on the outside of the vehicle.

2. The radio apparatus according to claim 1, wherein the communicating unit stops the reception processing unit and causes the transmission processing unit to continue to operate.

3. A radio apparatus for executing 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;

a communicating unit configured to operate a transmission processing unit for executing a transmission process to transmit a packet signal including a positional information of the radio apparatus and operate a reception processing unit for executing a reception process to receive a packet including a positional information of the another radio apparatus when the estimating unit estimates that the radio apparatus is present in the vehicle;

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

a battery configured to drive the radio apparatus when 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 when the radio apparatus is driven by the battery, and

the communicating unit stops one of the transmission processing unit and the reception processing unit when the estimating unit estimates that the radio apparatus is present on the outside of the vehicle.

4. The radio apparatus according to claim 3, wherein the communicating unit stops the reception processing unit.
