Abstract: Handoffs in a mobile cellular communications environment will become an increas-ingly important issue as cell sizes shrink to accommodate an increasingly large demand for service. CDMA cellular systems use soft handoff. To cope with the channel shortages, many schemes were proposed. In this paper, a new handoff scheme is proposed that is called the handoff algorithm based on channel borrowing and signal prediction priority queuing. If there is no idle channel when the handoff requests arrive the cell, it will borrow channels from station-ary calls participating in soft handoff and allocate the borrowed channels to handoff requests by moving calls. If there is no channel can be borrowed, it will put handoff requests into queue, using signal prediction priority queuing method. A comparison is made between the performances of the proposed scheme.and other schemes.
