In heavy traffic cellular networks low priority handover requests will increase handover drops. In current handover queuing schemes, slow signal strength changing mobile units with low priority handover requests can occupy the handover queue space. As a result, high priority requests will be dropped. This effect could be eliminated utilizing a new scheme called Comparative Queuing. Prioritization method has been modified to include the possibility of termination of calls for the mobile units waiting in the handover queue. This scheme with lower queue sizes outperforms the existing dynamic priority queuing schemes under heavy traffic conditions. Simulation is conducted for a cluster of seven cells to incorporate interaction between cells. Simulation results confirm the reduction in handover drops.
