ABSTRACT

Channel Reservations vs. PACA Queuing: A Comparison of Priority Call Handling Techniques   [open pdf - 554KB]

Recently, the Technology and Standards Division of the National Communications System (NCS) completed a study that compares channel reservation and priority access channel allocation (PACA) queuing. The study simulated these priority call handling techniques under stress to observe how the techniques would handle periods of extreme congestion. The results of this study are clear: the PACA queuing technique consistently handles network stress most efficiently, providing the best completion rates to national security/emergency preparedness (NS/EP) callers. This Technical Note explores how channel reservation and PACA queuing treat priority calls, analyzes the simulation's results and presents implications of this study to NS/EP users.
