  • Patent number: 11405434
    Abstract: A communication system includes a first communication terminal; and two or more second communication terminals that share shared data with each other. The first communication terminal transmits the shared data; and transmits, to the second communication terminal that has transmitted a share completion report indicating that sharing of the shared data has been completed, a share status report indicating that there is the second communication terminal that has not yet transmitted the share completion report, based on whether the share completion report has been received from the second communication terminal. The second communication terminal receives the shared data; and displays the share status report indicating that there is the second communication terminal that has not yet transmitted the share completion report, upon receiving the share status report indicating that there is the second communication terminal that has not yet transmitted the share completion report.
