COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND PROGRAM
First Claim
1. A communication apparatus comprising:
- a communication unit for performing a close-range one-to-one communication with a device of a communication counterpart by electric field coupling or magnetic field coupling;
an intermittent operation unit for performing intermittent operation without releasing connection after the connection is established with the device of the communication part;
an intermittent operation notifying unit for notifying the device of the communication counterpart of performing the intermittent operation, the intermittent operation notifying unit notifying without receiving a response to the notification; and
an intermittent operation cancel request unit for outputting a cancel request of canceling the intermittent operation of the device of the communication counterpart when transmitting a data frame to the device of the communication counterpart and a response with respect to the data frame is not received from the communication counterpart.

6. A program for causing a computer to function as:
-
means for performing a close-range one-to-one communication with a device of a communication counterpart by electric field coupling or magnetic field coupling; means for performing intermittent operation without releasing connection after the connection is established with the device of the communication part; means for notifying the device of the communication counterpart of performing the intermittent operation, the unit notifying without receiving a response to the notification; and means for outputting a cancel request of canceling the intermittent operation of the device of the communication counterpart when transmitting a data frame to the device of the communication counterpart and a response with respect to the data frame is not received from the communication counterpart.
