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

摘要

In order to make possible 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 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 unit after the first signal including the stop transmission request information is transmitted.
