COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, AND COMPUTER READABLE MEDIUM
First Claim
1. A communication apparatus connected to a relay apparatus via a first communication path and a second communication path, the relay apparatus relaying communication performed with a source communication apparatus, the first communication path being used for communication using a first communication standard, the second communication path being used for communication using a second communication standard, the communication apparatus comprising:
- a communication start request receiving unit that receives, via the first communication path, a communication start request that is output from the source communication apparatus and is transmitted via the relay apparatus; and
a response notification output unit that outputs a first response notification or a second response notification to the relay apparatus via the first communication path when the communication start request receiving unit receives, via the first communication path, a communication start request for starting communication using the second communication standard in a case where the number of apparatuses with which the communication apparatus is communicating using the second communication standard has reached a predetermined number, the first response notification indicating that communication is being performed, the second response notification having a lower priority than the first response notification in an arbitration process of arbitrating between pieces of information output from the relay apparatus, the arbitration process being executed by the relay apparatus.

Abstract
A communication apparatus includes a communication start request receiving unit and a response notification output unit. The communication start request receiving unit receives, via a first communication path, a communication start request that is output from a source communication apparatus and is transmitted via a relay apparatus. The response notification output unit outputs a first response notification or a second response notification to the relay apparatus via the first communication path when the communication start request receiving unit receives, via the first communication path, a communication start request for starting communication using a second communication standard in a case where the number of apparatuses with which the communication apparatus is communicating using the second communication standard has reached a predetermined number. The first response notification indicates that communication is being performed. The second response notification has a lower priority than the first response notification in an arbitration process.
