COMMUNICATION DEVICE, COMMUNICATION SYSTEM, COMMUNICATION DEVICE CONTROL METHOD, AND COMMUNICATION DEVICE CONTROL PROGRAM

摘要

In order to enable stopping of a receive operation without stopping the communication operation of an external communication device while the effects on the reception of signals from the communication device are suppressed as much as possible, a communication device comprises: a transmission means for transmitting a first signal during a specified time interval to an external communication device provided with a stop transmission function for stopping transmission; and a reception means which is provided with a stop reception function for stopping reception, and receives a second signal transmitted by the external communication device. The communication device also comprises a stop transmission request means which includes in the first signal the stop transmission request information for requesting the stopping of the transmission of the second signal to the external communication device, and a stop reception means which stops the receive operation of the reception means after the first signal including the stop transmission request information is transmitted.
