1. An electronic device for performing video communication, the electronic device comprising:

  • a memory storing instructions; and

    a processor configured to execute the stored instructions to at least;

    control to perform the video communication with an external device using a mobile communication network, the video communication with the external device using the mobile communication network comprising sending video communication data towards the external device through a mobile communication interface of the electronic device and receiving video communication data originating from the external device through the mobile communication interface, wherein video communication data sent towards the external device includes image data obtained through a camera of the electronic device,control to display a video image of the video communication being performed with the external device using the mobile communication network on a touch screen of the electronic device,while displaying the video image of the video communication being performed with the external device using the mobile communication network, control to identify one or more wireless local area networks (WLANs) available at a current location of the electronic device based on a signal of each of the one or more WLANs,based on the identifying of the one or more WLANs, control to display, on the touch screen, one or more user interface items that respectively correspond to the identified one or more WLANs along with the video image of the video communication being performed with the external device using the mobile communication network, wherein each of the displayed one or more user interface items allows for selecting a corresponding WLAN through which to perform the video communication with the external device, wherein each of the one or more user interface items includes signal strength information for a corresponding WLAN,in response to receiving, through the touch screen, a first user touch input for a user interface item of the displayed one or more user interface items while displaying the video image of the video communication being performed with the external device using the mobile communication network, control to select a WLAN corresponding to the user interface item,in response to receiving, through the touch screen, a second touch input for connecting to the selected WLAN while displaying the video image of the video communication being performed with the external device using the mobile communication network, control to initiate an operation to change a communication network for the video communication from the mobile communication network to the selected WLAN, andcontrol to perform, with the external device using the selected WLAN to which the communication network for the video communication is changed from the mobile communication network, the video communication, the video communication with the external device using the WLAN comprising sending video communication data towards the external device through a WLAN communication interface of the electronic device and receiving video communication data originating from the external device through the WLAN communication interface, wherein video communication data sent towards the external device includes image data obtained through the camera of the electronic device.
