This paper presents a procedure for estimating the mean access delay of calls in public access mobile radio (PAMR) trunking systems. For this purpose, an approximation of the mean waiting time in the M/G/C queue with non-preemptive priority is developed and numerically tested. The proposed approximation is based on other existing approximations and has been tested for the conditions commonly found in PAMR systems with very accurate results.
