Abstract: A model for RAU selection is presented, in which the active set (AS) is comprised of selected RAUs and serves for the mobile station. Based on this, we propose a handoff model in distributed radio mobile communication system. The received signal strength(RSS) threshold of handoff is controlled by average power of the AS adaptively. Performance analysis shows that numerical data obtained from the model are in good agreement with simulation results.

Key words: distributed radio mobile communications system, handoff, RAU selection criterion, active set
