Summary One of the key performance in wireless cellular system is the handoff dropping probability. This paper studies the handoff performance for an integrated voice/data wireless cellular system. Specifically, we propose a new handoff control policy, called Dual Trunk Reservation with Queuing (DTR-Q). It uses two thresholds, one to reserve bandwidth for voice handoff, and the other for managing the data traffic. By taking advantage of the adaptiveness of data traffic, it uses a single queue to further buffer the data request in case the requested bandwidth is not available. The unique features of the proposed DTR-Q scheme are: 1) it can provide the necessary service guarantee and service differentiation for voice and data traffic; 2) It adopts a Complete Sharing approach that can maximize the channel utilization. We propose an analytical model to calculate the key performance measures, and. thoroughly investigate system performances under a variety of system parameters.
