  • Seamless handover method in an FH-OFDM based mobile communication system
    Publication number: 20050143072
    Abstract: A handoff method in a mobile communication system using frequency hopping-orthogonal frequency division multiplexing (FH-OFDM). A mobile host predicts a handoff according to strength of transmission power of a currently serving base station, reserves a physical channel required for the handoff associated with at least one candidate base station, selects a handoff target base station from the at least one candidate base station, releases a channel with the serving base station, and performs data communication with the target base station through the reserved physical channel.
