The method includes performing, by a user equipment (UE), video communication through a mobile communication network; searching for whether there is a wireless local area network (WLAN) accessible by the UE; displaying, if a WLAN accessible by the UE is found, the accessible WLAN; and when the displayed WLAN is selected by a user, changing a communication network for the video communication to perform the video communication through the selected WLAN. ## Claims ### Claim 1 An electronic device for performing video communication, the electronic device comprising: a touch screen; a memory storing instructions; and at least one processor configured to execute the instructions to at least: control to perform, through a communication interface of the electronic device, the video communication with an external device, control to identify at least one video communication device capable of performing the video communication with the external device while performing the video communication with the external device, while performing the video communication with the external device, control to display, on the touch screen, the identified at least one video communication device capable of performing the video communication with the external device, while performing the video communication with the external device, control to obtain a touch input, via the touch screen, for selecting one of the identified at least one video communication device displayed on the touch screen, and based on one of the identified at least one video communication device being selected, control to initiate an operation to change a device for the video communication from the electronic device to the selected one of the identified at least one video communication device while performing the video communication with the external device. ### Claim 2 (depends on 1) The electronic device of claim 1, further comprising: a camera to obtain an image during the video communication. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the at least one processor is further configured to control to display, on the touch screen, a video image of the video communication being performed with the external device. ### Claim 4 (depends on 2) The electronic device of claim 2, wherein the at least one processor is further configured to control to perform the video communication with the external device by sending video communication data towards the external device through the communication interface and by receiving video communication data originating from the external device through the communication interface, and wherein the video communication data sent towards the external device includes a video image obtained through the camera of the electronic device. ### Claim 5 (depends on 2) The electronic device of claim 2, wherein the at least one processor is further configured to control to display at least one user interface item together with a video image of the video communication being performed with the external device, the at least one user interface item respectively correspond to the identified at least one video communication device. ### Claim 6 (depends on 5) The electronic device of claim 5, wherein each of the displayed at least one user interface item includes type information and name for a corresponding video communication device. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the memory stores information of the at least one video communication device capable of performing the video communication with the external device. ### Claim 8 A method for performing video communication by an electronic device, the method comprising: performing, through a communication interface of the electronic device, the video communication with an external device, while performing the video communication with the external device, identifying at least one video communication device capable of performing the video communication with the external device, while performing the video communication with the external device, displaying, on a touch screen of the electronic device, the identified at least one video communication device capable of performing the video communication with the external device, while performing the video communication with the external device, obtaining a user touch input, via a touch screen of the electronic device, for selecting one of the identified at least one video communication device displayed on the touch screen, and based on one of the identified at least one video communication device being selected, initiating an operation to change a device for the video communication from the electronic device to the selected one of the identified at least one video communication device while performing the video communication with the external device. ### Claim 9 (depends on 8) The method of claim 8, wherein the performing the video communication with the external device comprises sending video communication data towards the external device through the communication interface and receiving video communication data originating from the external device through the communication interface, and wherein the video communication data sent towards the external device includes a video image obtained through a camera of the electronic device. ### Claim 10 (depends on 8) The method of claim 8, further comprising: displaying a video image of the video communication being performed with the external device. ### Claim 11 (depends on 8) The method of claim 8, further comprising: displaying at least one user interface item together with the a video image of the video communication being performed with the external device, wherein the at least one user interface item respectively correspond to the identified at least one video communication device. ### Claim 12 (depends on 11) The method of claim 11, wherein each of the displayed at least one user interface item includes type information and name for a corresponding video communication device. ### Claim 13 (depends on 8) The method of claim 8, wherein information of the at least one video communication device capable of performing the video communication with the external device. ### Claim 14 A non-transitory computer readable storage medium with instructions stored thereon, the instructions executable by a processor of an electronic device for performing a video communication to cause the processor to at least: control to perform, through a communication interface of the electronic device, the video communication with an external device, control to identify at least one video communication device capable of performing the video communication with the external device while performing the video communication with the external device, while performing the video communication with the external device, control to display, on a touch screen of the electronic device, the identified at least one video communication device capable of performing the video communication with the external device, while performing the video communication with the external device, control to obtain a touch input, via a touch screen of the electronic device, for selecting one of the identified at least one video communication device displayed on the touch screen, and based on one of the identified at least one video communication device being selected, control to initiate an operation to change a device for the video communication from the electronic device to the selected one of the identified at least one video communication device while performing the video communication with the external device.
