A dual dynamic threshold access scheme for handoff prioritization is proposed. By dynamically adjusting the value of both thresholds, the system resource utilization can be improved with a better overall system award. Two-dimensional Markov process traffic models for cellular mobile systems are formulated and analyzed. It is verified by the numerical simulations that the DDT-GC-VBR scheme can provide the necessary service guarantee. At the same time, it can decrease the handoff dropping probability and forced termination probability, while improve the system resource utilization. (4 pages)
