Abstract

Claims (49)

1. A system for identifying communication problems comprising:

a telecommunications network;

one or more telecommunications probes coupled to the telecommunications network, the telecommunications probes capable of generating detailed records describing one or more network events;

one or more processors in communication with the telecommunications probes; and

memory coupled to the one or more processors, the memory storing the detailed records received by the telecommunications probes and the memory storing instructions executable by the one or more processors, the instructions operable to:

identify detailed records that indicate an event failure including error codes and associated subscriber identifiers;

learn a distribution of error codes and associated subscriber identifiers;

detect event failures that indicate an increase in the number of subscriber identifiers for an error code;

analyze attributes of the detected event failures to identify one or more common attributes between the detected event failures;

prepare a report identifying a network issue based on the identified one or more common attributes between the detected event failures;

transmit the report; and

receive feedback based on the report.

2. The system of claim 1 , wherein an event comprises at least one of: phone on, phone connecting to the network, acquiring new base station, SMS, a data session, a phone registering on the network, or Internet access.

3. The system of claim 1 , wherein the increase in the number of subscriber identifiers for an error code crosses a threshold condition.

4. The system of claim 1 , wherein the common attributes to identify are listed in a configuration file.

5. The system of claim 1 , wherein the attributes comprise at least one of:

telephone numbers of requesting and receiving devices, location of devices, communication paths used, base station, signal tower, time, GGSN, SGSN, handset, network element, APN, cell technology, radio technology, roaming type, country, carrier, source number, destination number, destination category, destination nature of address, destination numbering plan, OPC/DPC, release location, routing natr, routing numbering plan, source category, source natr, source numbering plan, teleservice information, transmission media requirement, trunk, quality attribute, or mean opinion score.

6. A method of identifying communication problems comprising:

loading, by a computer, a first plurality of detailed records, wherein the detailed records contain attributes for one or more network events;

identifying, by the computer, a second plurality of detailed records from the first plurality of detailed records, wherein the second plurality of detailed records indicate an event failure;

detecting, by the computer, a signature in the second plurality of detailed records, wherein the signature is a pattern indicating a known failure type and associated attributes;

learning, by the computer, a typical pattern of attributes associated with the signature;

identifying, by the computer, a deviation from the learned pattern;

detecting, by the computer, one or more common attributes in a plurality of event failures based on the deviation from the learned pattern;

determining, by the computer, a problem based on the one or more common attributes in a plurality of event failures;

reporting, by the computer, the problem; and

receiving, by the computer, input on the problem.

7. The method of claim 6 , wherein deviations may be a percentage deviation in an attribute or an increase in the number of users affected by the network event.

8. The method of claim 6 , wherein the one or more common attributes are listed in a configuration file.

9. The method of claim 6 , wherein the one or more common attributes in a plurality of event failures comprises at least one of:

telephone numbers of requesting and receiving devices, location of devices, communication paths used, base station, signal tower, time, GGSN, SGSN, handset, network element, APN, cell technology, radio technology, roaming type, country, carrier, source number, destination number, destination category, destination nature of address, destination numbering plan, OPC/DPC, release location, routing natr, routing numbering plan, source category, source natr, source numbering plan, teleservice information, transmission media requirement, trunk, quality attribute, or mean opinion score.

10. The method of claim 6 , wherein input on the problem comprises one of an indication that future reports with the same attributes will be suppressed or an indication that future reports with the same attributes will be encouraged.

11. The method of claim 6 , wherein the one or more network events comprise at least one of: phone on, phone connecting to the network, acquiring new base station, SMS, a data session, a phone registering on the network, or Internet access.

12. A non-transitory computer-readable medium comprising instructions executable by one or more processors to identify communication problems, the computer-readable medium comprising one or more instructions for:

loading a first plurality of detailed records, wherein the detailed records contain attributes for one or more network events;

identifying a second plurality of detailed records from the first plurality of detailed records, wherein the second plurality of detailed records indicate an event failure;

detecting a signature in the second plurality of detailed records, wherein the signature is a pattern indicating a known failure type and associated attributes;

learning a typical pattern of attributes associated with the signature;

identifying a deviation from the learned pattern;

detecting one or more common attributes in a plurality of event failures based on the deviation from the learned pattern;

determining a problem based on the one or more common attributes in a plurality of event failures;

reporting the problem; and

receiving input on the problem.

13. The computer-readable medium of claim 12 , wherein deviations may be a percentage deviation in an attribute or an increase in the number of users affected by the network event.

14. The computer-readable medium of claim 12 , wherein the one or more common attributes between a plurality of event failures comprises at least one of:

telephone numbers of requesting and receiving devices, location of devices, communication paths used, base station, signal tower, time, GGSN, SGSN, handset, network element, APN, cell technology, radio technology, roaming type, country, carrier, source number, destination number, destination category, destination nature of address, destination numbering plan, OPC/DPC, release location, routing natr, routing numbering plan, source category, source natr, source numbering plan, teleservice information, transmission media requirement, trunk, quality attribute, or mean opinion score.

15. The computer-readable medium of claim 12 , wherein input on the problem comprises one of an indication that future reports with the same attributes will be suppressed or an indication that future reports with the same attributes will be encouraged.

16. The computer-readable medium of claim 12 , wherein the one or more common attributes are listed in a configuration file.

17. The computer-readable medium of claim 12 , wherein the one or more network events comprise at least one of: phone on, phone connecting to the network, acquiring new base station, SMS, a data session, a phone registering on the network, or Internet access.
