ANALYSIS OF A CUTOFF PRIORITY CELLULAR RADIO SYSTEM WITH FINITE QUEUING AND RENEGING DROPPING/

Queueing of new or handoff calls can minimize blocking probabilities o r increase total carried traffic. This paper investigates a new cutoff priority cellular radio system that allows Smite queueing of both new and handoff calls. We consider the reneging from the system of queued new calls due to caller impatience and the dropping of queued handoff calls by the system as they move out of a handoff area before being a ccomplished successfully. We use signal-flow graphs and Mason's formul a to obtain the blocking probabilities of new and handoff calls and th e average waiting times. Moreover, an optimal cutoff parameter and app ropriate queue sizes for new and handoff calls are numerically determi ned so that a proposed overall blocking probability is minimized.
