Abstract
In the multi-casting communication system, on receipt of a signal transmitted from one of mobile communication terminals with a half-duplex communication switch thereof being on, the PoC server records a user of the mobile communication terminal in a subscriber list as a next speaker, if there is another mobile communication terminal presently making multi-casting communication, and further if no mobile communication terminals are recorded in the subscriber list. Thus, it is clear who speaks next.
