1. A method for performing video communication by an electronic device, the method comprising:

  • performing the video communication with an external device using a mobile communication network by sending video communication data towards the external device through a mobile communication interface of the electronic device and by receiving video communication data originating from the external device through the mobile communication interface of the electronic device, wherein video communication data sent towards the external device includes image data obtained through a camera of the electronic device;

    displaying 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;

    identifying, by the electronic device, one or more wireless local area networks (WLANs) available at a current location of the electronic device based on a signal received from each of the one or more WLANs,selecting, by the electronic device, a WLAN from the identified one or more WLANs, andinitiating, by the electronic device, an operation to change a communication network for the video communication from the mobile communication network to the selected WLAN; and

    performing, 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 by sending video communication data towards the external device through a WLAN communication interface of the electronic device and by receiving video communication data originating from the external device through the WLAN communication interface of the electronic device, wherein video communication data sent towards the external device includes image data obtained through the camera of the electronic device,wherein, while displaying the video image of the video communication being performed with the external device using the mobile communication network, the selecting of the WLAN from the identified one or more WLANs comprises;

    based on access information stored in a memory of the electronic device, determining whether any of the identified one or more WLANs is previously accessed, the access information being stored when a WLAN is accessed by the electronic device,based on determining that a WLAN of the identified one or more WLANs is previously accessed, automatically selecting the WLAN determined to be previously accessed, andbased on determining that none of the identified one or more WLANs is previously accessed, selecting a WLAN corresponding to a user interface item selected by a user touch input for the user interface item from one or more user interface items displayed on the touch screen, wherein the one or more user interface items respectively correspond to the identified one or more WLANs, and wherein each of the displayed one or more user interface items includes signal strength information for a corresponding WLAN.
