When the new host terminal 100-2 is determined, pieces of address information of respective participant terminals of the first group stored in the host terminal 100-1 are provided on the determined communication terminal 100-2. The communication terminal 100-2 acquiring the pieces of address information starts second group communication while setting respective communication terminals (excluding the preceding host terminal 100-1) included in the pieces of address information as participant terminals and setting the communication terminal 100-2 itself as a host terminal. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
