Abstract :
The performance of a slotted ALOHA based GSM access network is evaluated for various traffic cases. The impact of optimized random access channel (RACH) slots on exponentially increasing total access traffic load is analyzed. The probability of success is estimated and related to the number of RACH slots per time unit. The traffic channel utilization rate is calculated for various channel holding time. The access throughput is presented for different RACH slots. The total access load is found to decrease with the increase in the probability of success for the same new packet generation rate. An optimized relation between the total access load and the new arrival rate for different RACH slots is presented.
