PURPOSE: A method for originating and releasing a multicall in the next generation mobile telecommunication network is provided to enable service supply of the multicall by providing destination and releasing signaling process of the multicall. CONSTITUTION: A multicall process function block stands by input of a call release request signal(S21), receives the call release request signal(S23-S27), and judges whether the call release request signal is provided from an origination side or a destination side(S29). If provided from the origination side, the multicall process function block judges whether a multicall flag is in multicall state or general call state(S31). If the general call, the multicall process function block releases resource to the corresponding mobile station(S33) and reports that the call of the origination station is released(S35). The multicall process function block requests the release of the call to the destination side by providing the call release signal to the destination side(S37) and terminates all call releasing process by releasing an SCCP(Signaling Connection Control Part) connection with the corresponding origination mobile station. If the multicall, the multicall process function block judges whether the origination mobile station requests the call release request signal(S39). If so, the multicall process function block retrieves assigned resource to the release-requested call(S41), and judges whether the number of call is 1(S43). If the number of call is more than 1, the multicall process function block requests to release the corresponding call for releasing the corresponding call and updating an inner call control table(S47).
