A portable device for supporting a call function, the portable device comprising: a radio frequency unit for performing a call connection between the portable device and at least a second device; a controller for controlling the call connection; an input unit for inputting a telephone number corresponding to the second device which makes a call connection through the radio frequency unit, and for generating an input signal to select phone book information associated with the second device; a display unit for outputting a first icon corresponding to the portable device itself and displayed on a user interface, and for outputting on the user interface, during a current call connection with a second device, a second icon representing the second device, the first and second icons being displayed overlapping or substantially touching to represent the current call connection; wherein in response to detecting an incoming call from a third device during the current call, the controller causes the user interface to display a third icon representing the third device at a location separated from each of the first and second icons; and during a state of receiving the incoming call, in response to detecting a single, predetermined user gesture involving only the first and third icons among all displayed icons, the controller controls an operation of automatically call-connecting the portable device and the third device and adjusting a relative position between the first and third icons so that they overlap or substantially touch to indicate a call-connected state therebetween, while automatically separating the second icon from the first icon on the user interface to indicate a hold state and placing the second device on hold with the portable device.
