Other embodiments are disclosed.

First claim

What is claimed is:

1. A method, comprising:
obtaining, by a system including a processor, a first baseline average power across a frequency range and a plurality of cell sites;
determining, by the system, a first threshold from the first baseline average power that is obtained;
obtaining, by the system, Signal to Interference plus Noise Ratio (SINR) measurements at the plurality of cell sites;
determining, by the system, whether one or more of the SINR measurements are below the first threshold;
initiating, by the system, corrective action to improve a SINR measurement of an affected cell site and corresponding path of the plurality of cell sites responsive to the SINR measurement of the affected cell site and corresponding path falling below the first threshold;
obtaining, by the system, a second baseline average power across the frequency range and the plurality of cell sites;
determining, by the system, a second threshold from the second baseline average power that is obtained; and
determining, by the system, whether the corrective action has improved the SINR measurement of the affected cell site and corresponding path according to the second threshold.

2. The method of claim 1 , further comprising reversing at least in part, by the system, the corrective action responsive to determining that the corrective action has not improved the SINR measurement of the affected cell site and corresponding path.

3. The method of claim 1 , further comprising determining, by the system, whether the corrective action has reduced a SINR measurement of other cell sites and corresponding paths responsive to determining that the SINR measurement of the affected cell site and corresponding path has improved.

4. The method of claim 3 , further comprising reversing at least in part, by the system, the corrective action responsive to determining that the SINR measurement of one or more other cell sites and corresponding paths has been reduced below an undesirable SINR threshold.

5. The method of claim 1 , wherein the first threshold is determined according to a time of day, an event affecting operations of the plurality of cell sites, a key performance indicator (KPI), or any combination thereof.

6. The method of claim 1 , wherein the initiating of the corrective action further comprises adjusting one or more KPIs of the affected cell site and corresponding path.

7. The method of claim 1 , wherein the SINR measurement for each of the plurality of cell sites comprises an average of SINR measurements according to a sampling size.

8. The method of claim 1 , wherein the corrective action comprises filtering adjacent signals, adjusting gain of an uplink, filtering interference signals, utilizing diversity signal paths, adjusting a pilot signal, adjusting transmit parameters, adjusting receive parameters, adjusting a modulation scheme, adjusting a coding scheme, adjusting a position of an antenna to reshape a coverage, or any combination thereof.

9. The method of claim 1 , wherein an interference component of the SINR measurement is based on measurements of signals that exceed an inter-cell threshold.

10. The method of claim 9 , wherein the inter-cell threshold comprises an average of inter-cell signal measurements.

11. The method of claim 9 , wherein the inter-cell threshold is above a thermal noise level.

12. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining a first threshold from a first baseline average power obtained across a frequency range and a plurality of cell sites;
obtaining Signal to Interference plus Noise Ratio (SINR) measurements from the plurality of cell sites;
identifying a SINR measurement of the SINR measurements that is below the first threshold;
identifying an affected cell site of the plurality of cell sites from which the SINR measurement was obtained;
initiating corrective action to improve the SINR measurement of the affected cell site;
determining a second threshold from a second baseline average power obtained over the frequency range and the plurality of cell sites; and
determining whether the corrective action has improved the SINR measurement of the affected cell site according to the second threshold.

13. The system of claim 12 , wherein the operations further comprise determining whether the corrective action has reduced one or more SINR measurements of one or more other cell sites of the plurality of cell sites.

14. The system of claim 13 , wherein the operations further comprise reversing at least in part the corrective action responsive to determining that one or more SINR measurements of one or more other cell sites has been reduced.

15. The system of claim 12 , wherein the operations further comprise reversing at in part the corrective action responsive to determining that the corrective action has not improved the SINR measurement of the affected cell site.

16. The system of claim 12 , wherein the operations further comprise reversing at in part the corrective action responsive to determining that the corrective action has marginally improved the SINR measurement of the affected cell site.

17. The system of claim 12 , wherein the SINR measurement of the affected cell site corresponds to the SINR measurement of a sector or path of the affected cell.

18. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
determining a first threshold from a first baseline average power obtained across a frequency range and a plurality of cell sites;
obtaining signal to noise measurements from the plurality of cell sites;
determining that a first signal to noise measurement from the signal to noise measurements is below the first threshold;
identifying an affected cell site of the plurality of cell sites from which the first signal to noise measurement was obtained;
determining whether an initial signal to noise measurement of the affected cell site changed to the first signal to noise measurement responsive to corrective action initiated by a first cell site of the plurality of cell sites to improve a signal to noise measurement of the first cell site, wherein the first cell site and the affected cell site are different cell sites; and
adjusting at least in part the corrective action initiated by the first cell site to improve the first signal to noise measurement of the affected cell site responsive to determining the initial signal to noise measurement changed to the first signal to noise measurement responsive to corrective action initiated by the first cell site.
