MOBILE TERMINAL FOR A GROUP CALL AND A GROUP CALL METHOD, CAPABLE OF ENDING A CALL OF SOME OF NON CONTROL TERMINALS FOR A GROUP CALL BY A CONTROL TERMINAL USER

摘要

PURPOSE: A mobile terminal for a group call and a group call method are provided to enable a control terminal user to confirm a non control terminal which ends the call when some of the non control terminals end a call.;CONSTITUTION: A control terminal connects non control terminals for a group call(S205). The control terminal receives a DTMF(Dual Tone Multi-Frequency) signal from some non control terminals to which call end commands are inputted(S230). The control terminal checks some non control terminals transmitting the DTMF signal by recognizing the DTMF signal. The control terminal displays call states of the checked some non control terminals as an end state(S245).;COPYRIGHT KIPO 2011
