Abstract

A signal transfer point distributes a plurality of messages to a plurality of service control points in accordance with a distribution plan. The distribution plan includes each of the service control points. Each of the plurality of messages from the signal transfer point is distributed to a corresponding one of the plurality of service control points in accordance with the distribution plan.

Claims

1. A method of distributing a plurality of messages from a signal transfer point to a plurality of service control points, the method comprising the steps of:

selecting (a) one of a plurality of predetermined distribution plans for distributing the plurality of messages among the plurality of service control points, each of the plurality of service control points being included in the selected distribution plan; and

distributing each of the plurality of messages from the signal transfer point to a corresponding one of the plurality of service control points in accordance with the selected distribution plan.

2. The method of claim 1 wherein the selected distribution plan includes a distribution sequence for the plurality of service control points, the distribution sequence including each of the service control points at least once, wherein the plurality of messages are sequentially distributed in accordance with the distribution sequence.

3. The method of claim 2 wherein the distribution sequence includes each of the service control points once and only once.

4. The method of claim 2 wherein the selected distribution plan further includes a respective count associated with a service control point of the plurality of service control points, wherein the respective count of messages is distributed to the service control point before proceeding to a subsequent service control point in the distribution sequence.

5. The method of claim 2 wherein the distribution sequence is cycled to distribute the plurality of messages.

6. The method of claim 1 wherein the selected distribution plan includes a respective distribution proportion for each of the plurality of service control points, wherein each service control point has a proportion of the plurality of messages distributed thereto based upon its respective distribution proportion.

7. The method of claim 6 wherein the plurality of messages is deterministically distributed to produce each respective distribution proportion.

8. The method of claim 6 wherein the plurality of messages is stochastically distributed to produce each respective distribution proportion.

9. The method of claim 1 further comprising the steps of:

determining that one of the plurality of service control points is malfunctioning; and

utilizing a modified distribution plan for distributing subsequent messages to the plurality of service control points.

10. The method of claim 1 wherein the occupancy of each of the plurality of service control points is greater than 50% during a peak usage period.

11. A method of distributing a plurality of messages from a signal transfer point to a plurality of service control points, the method comprising the steps of:

selecting a distribution plan for distributing the plurality of messages among the plurality of service control points, each of the plurality of service control points being included in the distribution plan, the distribution plan selected from a plurality of predetermined distribution plans;

distributing each of the plurality of messages from the signal transfer point to a corresponding one of the plurality of service control points in accordance with the distribution plan, wherein the occupancy of each of the plurality of service control points is greater than 50% during a peak usage period;

determining that one of the plurality of service control points is malfunctioning; and

utilizing a modified distribution plan for distributing subsequent messages to the plurality of service control points.

12. A signal transfer point operative to distribute a plurality of messages to a plurality of service control points, each of the plurality of messages being distributed to a corresponding one of the plurality of service control points in accordance with a selected one of a plurality of predetermined distribution plans, the selected distribution plan including each of the plurality of service control points.

13. The signal transfer point of claim 12 wherein the selected distribution plan includes a distribution sequence for the plurality of service control points, the distribution sequence including each of the service control points at least once, wherein the plurality of messages are sequentially distributed in accordance with the distribution sequence.

14. The signal transfer point of claim 13 wherein the distribution sequence includes each of the service control points once and only once.

15. The signal transfer point of claim 13 wherein the selected distribution plan further includes a respective count associated with a service control point of the plurality of service control points, wherein the respective count of messages is distributed to the service control point before proceeding to a subsequent service control point in the distribution sequence.

16. The signal transfer point of claim 13 wherein the distribution sequence is cycled to distribute the plurality of messages.

17. The signal transfer point of claim 12 wherein the selected distribution plan includes a respective distribution proportion for each of the plurality of service control points, wherein each service control point has a proportion of the plurality of messages distributed thereto based upon its respective distribution proportion.

18. The signal transfer point of claim 17 wherein the plurality of messages is deterministically distributed to produce each respective distribution proportion.

19. The signal transfer point of claim 17 wherein the plurality of messages is stochastically distributed to produce each respective distribution proportion.

20. The signal transfer point of claim 12 further operative to determine that one of the plurality of service control points is malfunctioning and to utilize a modified distribution plan for distributing subsequent messages to the plurality of service control points.

21. The signal transfer point of claim 12 wherein the occupancy of each of the plurality of service control points is greater than 50% during a peak usage period.

22. A telecommunication system comprising:

a plurality of service control points; and

a signal transfer point operative to distribute a plurality of messages to the plurality of service control points, each of the plurality of messages being distributed to a corresponding one of the plurality of service control points in accordance with a selected one of a plurality of predetermined distribution plans, the selected distribution plan including each of the plurality of service control points.
