Abstract

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_resource, of that particular call-related event to be allocated memory. The holding rate is then used by ┌R_resource +7{square root over (R_resource)}┐ to determine the number of resources required to be allocated to the call-related event.

Claims

1. A method for allocating system resources in a radiotelephone system, the radiotelephone system providing operational measurements, handling calls, and having call related features, the method comprising the steps of:

determining an average number of system resources required per call-related event;

determining a holding rate based on the average number of system resources required per call-related event and Busy Hour Call Attempts (“

BHCA”

);

estimating a number of system resources needed based on the holding rate of the system resource; and

allocating the estimated number of system resources for each call-related event or feature,

wherein the allocation of the system resource increases system reliability and reducing operation costs.

2. The method of claim 1 wherein the step of determining the average number of system resources includes the steps of:

generating a call model frequency in response to the operational measurements; and

determining an average holding time for the system resources relating to the call model.

3. The method of claim 1 wherein the step of determining the average number of system resources includes the step of determining a number of times that a call-related event is required.

4. The method of claim 1 wherein the step of determining the holding rate includes determining a ratio of High Day Busy Hour to Average Busy Season Busy Hour.

5. The method of claim 4 wherein the ratio is 1.5.

13. The method of claim 1 wherein the system resource includes one or more memory blocks.

14. The method of claim 13 wherein the step of allocating includes providing a buffer of memory blocks in addition to the estimated memory blocks.

6. A method for allocating at least one system resource in a radiotelephone system, the radiotelephone system providing operational measurements, handling calls, and having call related features, the method comprising the steps of:

determining an average number of system resources required per call-related event;

determining a holding rate of the system resource, R_resource, based on the average number of system resources required per call-related event and Busy Hour Call Attempts (“

BHCA”

);

estimating a number of system resources required by ┌

R_resouce+7{square root over (R_resource)}┐

; and

allocating the estimated system resources for each call-related event or feature.

7. The method of claim 6 wherein the step of determining the average number of system resources includes the steps of:

generating a call model frequency in response to the operational measurements; and

determining an average holding time for the operational measurements relating to the call model.

8. The method of claim 6 wherein the step of determining the average number of system resources includes the step of determining a number of times that a call-related event is required.

9. The method of claim 6 wherein the step of determining the holding rate includes determining a ratio of High Day Busy Hour to Average Busy Season Busy Hour.

10. The method of claim 9 wherein the ratio is 1.5.

15. The method of claim 6 wherein the system resource includes one or more memory blocks.

11. A method for allocating at least one system resource in a radiotelephone system, the radiotelephone system providing operational measurements, handling calls, and having call related features, the method comprising the steps of:

determining an average number of system resources required per call-related event;

determining a holding rate of the system resource, R_resource, by ((1.5·

BHCA·

X_resource)/3600); and

estimating a number of system resources required by ┌

R_resouce+7{square root over (R_resource)}┐

; and

allocating the estimated system resources for each call-related event or feature.

16. The method of claim 11 wherein the system resource includes one or more memory blocks.

12. A method for allocating at least one system resource in a radiotelephone system, the radiotelephone system providing operational measurements, handling calls, and having call related features, the method comprising the steps of:

generating a call model frequency in response to the operational measurements;

determining an average holding time for the system resources relating to the call model frequency;

determining a number of times that a call-related event is required;

determining an average number of system resources required per call-related event in response to the call model frequency, the average holding time, and the number of times the call-related event is required;

determining a holding rate of the system resource, R_resource, by ((1.5·

BHCA·

X_resource)/3600);

estimating a number of system resources required by ┌

R_resource+7{square root over (R_resource)}┐

; and

allocating the estimated system resource for each call-related event or feature.

17. A method for provisioning system memory blocks and associated hardware in a radiotelephone system, the radiotelephone system providing operational measurements, handling calls, and having call related features, the method comprising the steps of:

determining an average number of the memory blocks required per call-related event;

determining a holding rate of the memory blocks, R_resource, by ((1.5·

BHCA·

X_recource)/3600);

estimating a number of the memory blocks required by ┌

R_resource+7{square root over (R_resource)}┐

; and

allocating the estimated number of memory blocks and associated hardware for each call-related event,

wherein the allocation of the memory blocks increases system reliability and reducing operation costs.
