Communication device and communication method

A communication method performed between a communication device and an external reader-writer apparatus, the communication method comprising:

• generating timer information;
• receiving time-of-day information from the external reader-writer apparatus through near-field communication;
• detecting operation information of the communication device and generating use history information on the basis of the time-of-day information received in the receiving of time-of-day information and the timer information, the use history information including operation time-of-day information associated with the detected operation information and indicating the time of day at which the corresponding operation was performed;
• and
• storing the use history information generated in the generating of use history information;
• wherein said receiving comprises:
• receiving a polling signal from the reader-writer apparatus;
• transmitting a polling response to the reader-writer apparatus to thereby establish the near-field communication;
• and
• receiving the time-of-day information from the reader-writer apparatus through the established near-field communication.

A communication device including a reader-writer that communicates with a terminal apparatus through near-field communication, the communication device comprising:

• a near-field communication establishment unit configured to transmit a polling signal to the terminal apparatus and receive a signal in response to the polling signal to thereby establish the near-field communication with the terminal apparatus;
• a session ID generation unit configured to generate a session ID for managing a session of the near-field communication;
• a time-of-day information extraction unit configured to extract time-of-day information from a clock device in the communication device after the near-field communication establishment unit establishes the near-field communication;
• a time-of-day storage unit configured to store the time-of-day information extracted by the time-of-day information extraction unit, in association with the session ID;
• a session ID transmission unit configured to transmit the session ID to the terminal apparatus through the near-field communication established by the near-field communication unit;
• a terminal information reception unit configured to receive operation status information of the terminal apparatus through the near-field communication, the operation status information being accompanied with timer information;
• and
• a terminal information update unit configured to (i) extract the time-of-day information stored in the time-of-day storage unit, on the basis of the session ID attached to the operation status information of the terminal apparatus accompanied with the timer information, and (ii) update the timer information accompanying the operation status information of the terminal apparatus to operation time-of-day information, on the basis of the extracted time-of-day information.
