Communication device and safety confirmation method

Abstract

A device having a first configuration includes an input unit configured to accept an input made by a user, and a transmitting unit configured to add a safety confirmation number accepted by the input unit to a first call control signal and to transmit the first call control signal with the safety confirmation number. A device having a second configuration includes a storing unit configured to store a safety confirmation text and a safety confirmation number by associating the safety confirmation text with the safety confirmation number, and a display unit configured to display the safety confirmation text that is stored in the storing unit correspondingly to the safety confirmation number added to a received first call control signal.

1 . A communication device, comprising:
 an input unit configured to accept an input made by a user; and   a transmitting unit configured to add, to a first call control signal, a safety confirmation number for identifying a message that is accepted by the input unit and stored on a receiving side, and to transmit the first call control signal with the safety confirmation number.   
   
   
       2 . The communication device according to  claim 1 , further comprising
 a display unit configured to display information, which indicates a safety state, based on information added to a received second call control signal.   
   
   
       3 . The communication device according to  claim 2 , further comprising
 a storing unit configured to store the safety confirmation number and a safety confirmation text by associating the safety confirmation number with the safety confirmation text, wherein:   the information added to the second call control signal includes the safety confirmation number, and information indicating a particular portion of the safety confirmation text; and   the display unit displays information corresponding to the safety confirmation number and the information indicating the particular portion of the safety confirmation text within the storing unit.   
   
   
       4 . The communication device according to  claim 2 , wherein
 the second call control signal is a disconnection signal.   
   
   
       5 . The communication device according to  claim 1 , further comprising
 an electronic mail transmitting unit configured to transmit electronic mail including the safety confirmation number and the safety confirmation text.   
   
   
       6 . The communication device according to  claim 1 , wherein
 the transmitting unit adds the safety conformation number, which is accepted by the input unit, to the first call control signal, and transmits the first call control signal with the safety conformation number to a plurality of transmission destinations.   
   
   
       7 . The communication device according to  claim 1 , wherein
 the first call control signal is a call connection request signal.   
   
   
       8 . A communication device, comprising:
 a communicating unit configured to communicate with a different device;   a display unit configured to display information;   an input unit configured to accept an input of information;   a storing unit configured to store safety confirmation information displayed on the display unit for safety confirmation, and safety confirmation identification information for identifying the safety confirmation information by associating the safety confirmation information with the safety confirmation identification information;   a determining unit configured to determine whether or not safety confirmation identification information is added to a call control signal received from the different device via the communicating unit; and   a controlling unit configured to read corresponding safety confirmation information from the storing unit based on added safety confirmation identification information if the safety confirmation identification information is added to the call control signal.   
   
   
       9 . The communication device according to  claim 8 , wherein
 the controlling unit identifies information that a user inputs with the input unit according to a display of the safety confirmation information, adds the input information to a call control signal, and causes the communicating unit to transmit the call control signal with the input information to the different device.   
   
   
       10 . The communication device according to  claim 9 , wherein
 the controlling unit causes the communicating unit to transmit the call control signal to the different device, if information is not input from the input unit within a predetermined duration from reception of the safety confirmation identification information.   
   
   
       11 . The communication device according to  claim 8 , wherein
 the controlling unit extracts safety confirmation information received from the different device, and safety conformation identification information corresponding to the safety confirmation information, and registers the safety confirmation information and the safety confirmation identification information in the storing unit by associating the safety confirmation information with the safety confirmation identification information.   
   
   
       12 . A safety confirmation method, comprising:
 accepting an input made by a user; and   adding a safety confirmation number input by the user to a first call control signal, and transmitting the first call control signal with the safety confirmation number.
