The provisioning process of the present invention first determines the average number of units of the system resource that are held per call. This parameter is a function of the call model and call-related event holding times. The average number of units is used, along with the Busy Hour Call Attempts to determine the holding rate, R,, of that particular call-related event to be allocated memory. The holding rate is then used by &boxdr;R,&plus;,{square root over (R,)}&boxdl; to determine the number of resources required to be allocated to the call-related event.

Process for provisioning resources in a radiotelephone network

The switch capacity prediction process of the present invention collects operational measurements from the cellular switch. These operational measurements indicate the frequency of the call events processed by the switch. The other input/output (I/O) time used by the call processor to process messages not related to call processing is separated from the call processing I/O time. A relationship between the other I/O time and the sum of the call processing time and call processing I/O time is determined. A weighted average is determined from the summation of the products of: the frequency of events and the call processing time, the frequency of events and the call processing I/O time, and the other I/O time. The weighted average is then divided into the call processor occupancy time, in hours, to determine the switch capacity.
