Abstract: Disclosed is a computer-implemented navigation method including transmitting, to a counterpart terminal, current location-based video data that is input to a video call screen of a terminal during a video call; receiving instruction information for a navigation based on the video data from the counterpart terminal that displays the video data on a video call screen of the counterpart terminal; generating navigation information by mapping the instruction information to the video data of the terminal; and providing the navigation information based on location information of the terminal.

Abstract: Provided is a method and system for automatically connecting a call of a Voice over Internet Protocol (VoIP) service. A method of automatically connecting the VoIP call in an electronic device implemented by a computer may include a setting a specific counterpart among counterparts capable of making the VoIP call over a network as an automatic connection target; and automatically connecting a call with the specific counterpart immediately in response to executing a program including a function of providing the VoIP call without performing a calling operation and an acceptance operation for a call between a user of the electronic device and the specific counterpart.

Abstract: A system and method for concealing bandwidth reduction of a VoIP call voice is provided. In a method for dynamic bandwidth extension during a call session between a first transceiver device and a second transceiver device, the first transceiver device compares a bit rate of received packet data with a threshold bit rate, and the first transceiver device determines whether to perform bandwidth extension during the call session based on the comparison. The bit rate is controlled based on a degree of network congestion between the first transceiver device and the second transceiver device.
