Abstract:
1. A handover apparatus of a terminal, the handover apparatus comprising: a received signal strength (RSS) measuring unit to measure an RSS from a currently accessed base station and RSSs from candidate base stations for handover; a radial velocity measuring unit to measure a radial velocity with respect to the currently accessed base station and radial velocities with respect to the candidate base stations for handover; a handover processor to perform a handover by determining a base station for handover based on the measured RSSs and the measured radial velocities when the RSS from the currently accessed base station is less than or equal to a reference RSS; re-measuring of the RSS from the currently accessed base station and RSSs from the candidate base stations for handover through the RSS measuring unit, after a predetermined period of time when the base station having the highest RSS is different from the base station having the lowest radial velocity; and the handover to the base station having a highest re-measured RSS when the base station having the highest re-measured RSS is different from the currently accessed base station.
