Communication device, communication system, and computer-readable medium

A communication device comprising:

• a communication start request output unit that outputs a communication start request to an output destination communication device;
• a response notification acceptance unit that accepts a response notification with respect to the communication start request from the output destination communication device;
• and
• an information output unit that outputs information to be output to the output destination communication device if the response notification acceptance unit accepts a response notification indicating that communications with the output destination communication device are acceptable, wherein
• when the response notification acceptance unit accepts a response notification indicating connection rejection due to a mismatch of a communication standard as the response notification with respect to the communication start request which is output in a first communication standard, the communication start request output unit again outputs the communication start request to the output destination communication device in a second communication standard which is different from the first communication standard,
• if the response notification acceptance unit accepts a response notification indicating that communications with the output destination communication device are acceptable to the communication start request which is output in the first communication standard, the information output unit outputs the information to be output in the first communication standard, and
• if the response notification acceptance unit accepts a response notification indicating that communications with the output destination communication device are acceptable to the communication start request which is output in the second communication standard, the information output unit outputs information whose amount is smaller than that of the information corresponding to the information to be output in the second communication standard.

A communication system comprising:

• a first communication device and a second communication device, wherein
• the first communication device includes:
• a communication start request acceptance unit that accepts a communication start request from the second communication device;
• and
• a response notification output unit that outputs a response notification in response to the communication start request to the second communication device,
• the second communication device includes:
• a communication start request output unit that outputs the communication start request to the first communication device;
• and
• a response notification acceptance unit that accepts the response notification in response to the communication start request from the first communication device, and
• when the response notification acceptance unit accepts a response notification indicating connection rejection due to a mismatch of a communication standard as the response notification in response to the output communication start request, the communication start request output unit again outputs the communication start request to the first communication device in a communication standard to which the output communication start request conforms.

A non-transitory computer-readable medium storing a program that causes a computer to execute communication processing, the communication processing comprising:

• outputting a communication start request to an output destination communication device;
• accepting a response notification with respect to the communication start request from the output destination communication device;
• and
• outputting again the communication start request to the output destination communication device in a communication standard to which the output communication start request conforms when the accepted response notification indicating connection rejection due to a mismatch of a communication standard as the response notification with respect to the output communication start request.
