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:

(a) 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 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;

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

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

2. The method of claim 1 further comprising:

(d) generating an alarm condition in response to the malfunction determined in (b).

3. The method of claim 1, wherein (b) comprises determining that one of the plurality of service control points is malfunctioning based upon a message received from one of the plurality of service control points.

4. The method of claim 3, wherein the message indicates the severity of the malfunction.

5. The method of claim 1, wherein (b) comprises determining that one of the plurality of service control points is malfunctioning based upon a duration between transferring a query message thereto and receiving a response message therefrom.

6. The method of claim 1, wherein (c) comprises omitting the service control point determined in (b) to be malfunctioning.

7. The method of claim 1, wherein (c) comprises reducing the share of messages distributed to the service control point determined in (b) to be malfunctioning.

8. The method of claim 1, wherein (c) comprises reducing the share of messages distributed to the service control point determined in (c) to be malfunctioning to zero.

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

10. 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 distribution plan including each of the plurality of service control points;

and 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.

11. The signal transfer point of claim 10 further operative to determine that one of the plurality of service control points is malfunctioning based upon a message received from one of the plurality of service control points.

12. The signal transfer point of claim 10 further operative to determine that one of the plurality of service control points is malfunctioning based upon a duration between transferring a query message thereto and receiving a response message therefrom.

13. The signal transfer point of claim 10 further operative to omit the service control point determined to be malfunctioning.

14. The signal transfer point of claim 10 further operative to reduce the share of messages distributed to the service control point determined to be malfunctioning.
