Estimation of peak load on trunked repeater systems

This paper discusses procedures for estimating the peak loads of trunked repeater systems. In addition to nominal peak load prediction, two aspects of overload are addressed: (1) system-to-system variation and (2) day-to-day variation. The procedures allow one to estimate the maximum communication load to be expected during a specified time interval for a specified fraction of trunked systems with equal mobile counts. One application of these procedures concerns the recent proposal of trunking at the 3 channel level. The results indicate that for most such systems to have viable grades-of-service, appreciably lower loading standards than exist today at the 5 channel level are necessary.
