Abstract

Systems and methods for dynamically modifying neighbor lists for cells within telecommunications networks and/or modifying neighbor lists based on determined radio frequency coupling between cells are described. In some embodiments, the systems and methods access a neighbor list associated with a target cell or associated with one or more neighbor cells of the target cell within a network, apply one or more dynamic optimization rule sets to the target cell, and modify a neighbor list associated with the target cell or with neighbor cells to the target cell based on the applied rule sets.

Claims (29)

1. A method, comprising:

determining a coupling value for a source cell and a neighbor cell within a telecommunications network; and

performing an action that is based on the determined coupling value, wherein determining a coupling value for the source cell and the neighbor cell includes:

calculating an azimuth of a vector between a location of the source cell and a location of the neighbor cell and an azimuth of an antenna of the source cell;

calculating an absolute value of a difference between the azimuth of the antenna of the source cell and the azimuth of the vector;

determining a geoscore for the source and the neighbor cell, the geoscore being a cosine of the calculated absolute value of the difference between the azimuth of the antenna of the source cell and the azimuth of the vector.

2. The method of claim 1 , wherein the determined coupling value is a geoscore that quantifies a degree of radio frequency coupling between the source cell and the neighbor cell.

3. The method of claim 1 , wherein the determined coupling value is based on an antenna relationship between the source cell and the neighbor cell and based on a coverage area relationship between the source cell and the neighbor cell.

4. The method of claim 1 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of neighbor seeding running within the telecommunications network.

5. The method of claim 1 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of blacklisting neighbor cells from neighbor lists running within the telecommunications network.

6. The method of claim 1 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of augmenting neighbor lists running within the telecommunications network.

7. A method, comprising:

determining a coupling value for a source cell and a neighbor cell within a telecommunications network; and

performing an action that is based on the determined coupling value, wherein determining a coupling value for the source cell and the neighbor cell includes:

calculating a distance between a location of the source cell and a location of the neighbor cell;

calculating an azimuth of a vector between a location of the neighbor cell and a location of the source cell;

calculating an absolute value of a difference between the azimuth of the antenna of the neighbor cell and the azimuth of the vector; and

determining a geoscore for the source and the neighbor cell, the geoscore being a cosine of the calculated absolute value of the difference between the azimuth of the antenna of the neighbor cell and the azimuth of the vector, minus the calculated distance between the location of the source cell and the location of the neighbor cell multiplied by a pre-determined weighting factor.

8. A non-transitory computer-readable storage medium whose contents, when executed by a computing system, cause the computing system to perform operations within running automated neighbor relation optimization processes, the operations comprising:

determining a coupling value for a source cell and a neighbor cell within a telecommunications network; and

performing an action that is based on the determined coupling value, wherein determining a coupling value for the source cell and the neighbor cell includes:

calculating an azimuth of a vector between a location of the source cell and a location of the neighbor cell and an azimuth of an antenna of the source cell;

calculating an absolute value of a difference between the azimuth of the antenna of the source cell and the azimuth of the vector;

determining a geoscore for the source and the neighbor cell, the geoscore being a cosine of the calculated absolute value of the difference between the azimuth of the antenna of the source cell and the azimuth of the vector.

9. The computer-readable storage medium of claim 8 , wherein the determined coupling value is a geoscore that quantifies a degree of radio frequency coupling between the source cell and the neighbor cell.

10. The computer-readable storage medium of claim 8 , wherein the determined coupling value is based on an antenna relationship between the source cell and the neighbor cell and based on a coverage area relationship between the source cell and the neighbor cell.

11. The computer-readable storage medium of claim 8 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of neighbor seeding running within the telecommunications network.

12. The computer-readable storage medium of claim 8 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of blacklisting neighbor cells from neighbor lists running within the telecommunications network.

13. The computer-readable storage medium of claim 8 , wherein performing an action that is based on the determined coupling value includes providing the coupling value to an automated network relation process of augmenting neighbor lists running within the telecommunications network.
