A multicall set-up and release method implements a multicall service in a next generation mobile communications system. If a multicall set-up is requested, the multicall is established in a signaling connection control part (SCCP) and infomation related to the multicall is stored in a call control table. On the other hand, if a multicall release is requested, the only call for which the call release is requested is released among calls in the multicall and a SCCP connection with a mobile station is maintained. However, if there exists only one established call in the multicall and the call release is requested for the call, not only the call is released but the SCCP connection is also disconnected with the mobile station.
