Abstract: Methods and apparatuses are provided for performing communication by a UE in a mobile communication system. A speed of the UE is measured by using an acceleration sensor in the UE. The UE determines that a change of the measured speed is detected in accordance with a predetermined criteria. The UE transmits information about the measured speed to a serving base station if the change of the measured speed is detected. Information about a target cell determined by the serving base station based on the measured speed is received from the serving base station. A handover procedure to the target cell is performed in response to receiving the information about the target cell.
