Analysis of a mobile cellular systems with hand-off priority and hysteresis control

In this paper, we introduce and analyze a new cut-off priority scheme which provides a better grade-of-service to hand-off traffic while maintaining high throughput for the originating calls. A hysteresis control is used for additional robustness. The system model is found to have a general level-dependent quasi-birth-and-death (QBD) structure. An efficient solution methodology is used taking full advantage of the problem structure. Our model extends, generalizes and unifies the existing models for cut-off priority schemes in wireless cellular networks
