Abstract: A dump output control apparatus includes a storage unit that stores output device information indicating an output device that is an output destination of dump information, a dump output device control unit that obtains the output device information stored in the storage unit and, determines a device as an output device for outputting the dump information thereto based on the obtained output device information, and a dump output unit that outputs the dump information to the determined output device.

Abstract: A communication control apparatus controls radio communications with other communication device through a relay device. The communication control apparatus includes a transmission control unit that notifies a data transmission to the relay device, and performs the data transmission to the relay device when the transmission control unit receives a response to the notification from the relay device indicating that the data transmission is possible, and stops a data transmission when the transmission control unit receives a response to a notification made by another communication device from the relay device, a collision conjecture unit that conjectures a collision of frames at the data transmission in accordance with a predetermined condition, and a threshold value control unit that sets a threshold value to determine an assertion or a negation of the transmission control unit in accordance with a result of the conjecture of the collision.
