Abstract

Methods and systems for providing optimization information for networks.

Claims

1. A system for providing optimization information in networks, the system comprising:

a network interface capable of providing data corresponding to a communication event;

at least one processor;

at least one computer usable medium having computer readable code embodied therein, the computer readable code be capable of causing said at least one processor to;

receive data, from a network, corresponding to a communication event,

determine, from the received data, a quality of service score for the communication event, and

determine, from the received data, a network resource utilization score for the communication event;

whereby a network can be optimized using the quality of service score and the network resource utilization score.

2. The system of claim 1 wherein the computer readable code, in causing said at least one processor to determine the quality of service score, further causes the at least one processor to:

obtain a quality of service indicator for the communication event;

compare the quality of service indicator to a predetermined quality of service expectations; and

determine the quality of service score from the comparison.

3. The system of claim 2 wherein the computer readable code, in causing said at least one processor to determine the quality of service indicator, further causes the at least one processor to determine a quality of service indicator for a voice system.

4. The system of claim 2 wherein the computer readable code, in causing said at least one processor to determine the quality of service indicator, further causes the at least one processor to determine an equipment impairment factor.

5. The system of claim 1 wherein the computer readable code, in causing said at least one processor to determine the network utilization score, further causes said at least one processor to:

obtain a network resource utilization indicator for the communication event;

compare the network resource utilization indicator to a predetermined network resource utilization expectation; and

determine the network resource utilization score from the comparison.

6. The system of claim 5 wherein the computer readable code, in causing said at least one processor to determine the network resource utilization indicator, further causes said at least one processor to determine a ratio of bits transferred during a given time to a bit rate.

7. The system of claim 1 wherein the computer readable code is capable of further causing said at least one processor to optimize a network performance according to a predetermined optimization criterion.

8. The system of claim 1 wherein said network interface comprises a computer readable medium having computer readable code embodied therein, said computer readable code be capable of causing said at least one processor to:

parse received messages corresponding to the communication event, and

extract said data corresponding to the communication event.

9. A method for providing optimization information in networks, the method comprising the steps of:

receiving information from a network for a communication event;

determining a quality of service score for the communication event;

determining a network resource utilization score for the communication event; and

whereby a network can be optimized using the quality of service score and the network resource utilization score.

10. The method of claim 9 wherein the step of determining the quality of service score comprises the steps of:

obtaining a quality of service indicator for the communication event;

comparing the quality of service indicator to a predetermined quality of service expectations; and

determining the quality of service score from the comparison.

11. The method of claim 10 wherein the step of determining the quality of service indicator comprises the step of determining a quality of service indicator for a voice system.

12. The method of claim 10 wherein the step of determining the quality of service indicator comprises the step of determining an equipment impairment factor.

13. The method of claim 9 wherein the step of determining the network resource utilization score comprises the steps of:

obtaining a network resource utilization indicator for the communication event;

comparing the network resource utilization indicator to a predetermined network resource utilization expectation; and

determining the network resource utilization score from the comparison.

14. The method of claim 9 further comprising the step of optimizing a network performance according to a predetermined optimization criterion.

15. A computer program product comprising:

a computer usable medium having computer readable code embodied there in, said computer readable code being capable of causing at least one processor to;

receive data, from a network, corresponding to a communication event,

determine, from the received data, a quality of service score for the communication event, and

determine, from the received data, a network resource utilization score for the communication event.

16. The computer program product of claim 15 wherein said computer readable code, in causing said at least one processor to determine the quality of service score, further causes the at least one processor to:

obtain a quality of service indicator for the communication event;

compare the quality of service indicator to a predetermined quality of service expectations; and

determine the quality of service score from the comparison.

17. The computer program product of claim 16 wherein the computer readable code, in causing said at least one processor to obtain the quality of service indicator, further causes said at least one processor to determine a quality of service indicator for a voice system.

18. The computer program product of claim 16 wherein the computer readable code, in causing said at least one processor to obtain the quality of service indicator, further causes said at least one processor to determine an equipment impairment factor.

19. The computer program product of claim 15 wherein said computer readable code, in causing said at least one processor to determine the network resource utilization score, further causes the at least one processor to:
