PROBLEM TO BE SOLVED: To provide a group communication control method capable of quickly confirming intention of an owner of a communication terminal who performs group communications. SOLUTION: A sponsor terminal 100-1 and participant terminals 100-2, 100-3, and 100-4 perform group communications represented by PTT (push to talk). The sponsor terminal 100-1 transmits a sheet recorded with the number of options and a reply time limit to the participant terminals 100-2, 100-3, and 100-4. The participant terminals 100-2, 100-3, and 100-4 selects an option and transmits back their reply the sponsor terminal 100-1. If the sponsor terminal 100-1 receives all of the reply from the participant terminal 100-2, 100-3, and 100-4 within the reply time limit, the sponsor terminal 100-1 totals the options automatically. As for a reply of a participant terminal received after the reply time limit, the sponsor terminal 100-1 regards the participant terminal as abstained from voting. COPYRIGHT: (C)2009,JPO&INPIT
