Abstract: A communication device is used in a mobile communication system switching alternately two communication time zones of a control channel (CCH) time zone in which communication using a control channel (CCH) is performed and a service channel time zone in which communication using a service channel is performed. A CCH transmission processor section transmits data using the control channel. When a generated data by a data generator section is determined by an importance determiner section to be equivalent to a data having a high-importance level, the generated data is transmitted in the CCH time zone by the CCH transmission processor section. By contrast, when the generated data is determined to be equivalent to a data having a low-importance level, the generated data is transmitted in the SCH time zone by the CCH transmission processor section.

Abstract: A mobile object communication system includes a mobile object side device used in a mobile object and a service provision device located outside the mobile object. The service provision device performs a communication with the mobile object side device for providing a predetermined service using one of multiple service channels, and transmits, using the control channel, service start information, which is required for starting the communication using the service channel and indicates the service channel used in the communication. The service provision device designates a communication method for performing the communication with the mobile object side device using the service channel indicated by the service start information. The service provision device transmits the service start information designating an immediate start method in a latter half of the control channel time period.

Abstract: A wireless communication device includes a short range receiving unit, a channel control unit for controlling a setting of a reception channel of the short range receiving unit to a control channel or a service channel, and an execution service determination unit. The channel control unit sets the reception channel as the control channel during a control channel time frame, and maintains the reception channel as the control channel during an extension time frame even after the short range receiving unit receives the service start information. The execution service determination unit performs an execution service determination process for determining, as an execution service, a service having the highest priority out of the services indicated by the service start information received by the short range receiving unit while the reception channel is set as the control channel by the channel control unit.

When the availability determiner determines that the service is unavailable, the communicator does not open a service channel designated by the service provider terminal.

Abstract: Vehicle exterior images are captured sequentially by an imaging portion of an imaging-equipped mobile terminal used in a first vehicle and stored temporarily in an image temporary-storage portion in the first vehicle. The first vehicle receives vehicle information from a second vehicle different from the first vehicle, through inter-vehicle communication. When it is determined that a sudden deceleration arises in the second vehicle based on the vehicle information received by the first vehicle, the vehicle exterior images stored in the image temporary-storage portion are read and saved in a memory.

The receiver receives information transmitted from each external communication apparatus located outside of a host vehicle via wireless communication.

A position of the outside target can be specified based on the position determination information. The reception frequency changing section decreases an information reception frequency of the receiver in accordance with an increase in the distance between the host vehicle and one of the outside targets closest to the host vehicle.

Abstract: A travel support system uses a wireless communication unit for receiving a following vehicle's speed control capacity, and compares the speed control capacity received with a speed control capacity of the subject vehicle. If the speed control capacity of the following vehicle is higher than the capacity of the subject vehicle, a maximum deceleration of the subject vehicle is restricted to a restricted value. In addition, a target inter-vehicle distance to a lead vehicle is set according to the restricted value of the subject vehicle, thereby enabling a reduction of the inter-vehicle distance to the lead vehicle for each of the vehicles in a convoy.
