Abstract: Disclosed herein are a method for handover in vehicular communications and On-Board Equipment (OBE) using the same. In the method for handover in vehicular communications, OBE performs a handover from first Road-Side Equipment (RSE) to second RSE. The OBE receives beacon frames from the first RSE and the second RSE. The first average value of a received signal strength indication corresponding to the beacon frame received from the first RSE and the second average value of a received signal strength indication corresponding to the beacon frame received from the second RSE are calculated. The first cumulative gradient of the first average value and the second cumulative gradient of the second average value are calculated. The handover from the first RSE to the second RSE is performed based on the first average value, the second average value, the first gradient, and the second gradient.
