Abstract

Systems, methods, and apparatus for self-optimizing Mobile Satellite System (MSS) resources are disclosed. In one or more embodiments, the disclosed method involves determining, with at least one processor, a communication demand for at least one cell in a MSS network. The method further involves determining, with at least one processor, whether the communication demand for at least one cell exceeds the capacity threshold for at least one cell. Further, the method involves reallocating, with at least one processor, when the communication demand for at least one cell exceeds the capacity threshold for at least one cell, at least a portion of the MSS resources such that at least one cell is able to meet the communication demand.

Claims

1. A method for self-optimizing mobile system resources, the method comprising:

determining, by at least one processor, a communication demand for at least one cell in a network, wherein the at least one cell is a polygon shape and at least one adjacent cell to the at least one cell is a polygon shape;

determining, by the at least one processor, that the communication demand for the at least one cell exceeds a capacity threshold for the at least one cell; and

reallocating, by the at least one processor, based on the determining of the communication demand for the at least one cell exceeds the capacity threshold for the at least one cell, at least a portion of the mobile system resources by redefining at least one vertex of the at least one adjacent cell to enlarge the at least one adjacent cell, according to how much the communication demand exceeds the capacity threshold for the at least one cell, such that at least a portion of the at least one adjacent cell covers at least a portion of the at least one cell and such that the respective communication demand for the at least one cell and the at least one adjacent cell is met;

wherein the reallocating of the at least a portion of the mobile system resources comprises allocating greater effective isotropic radiation power (EIRP) to the at least one cell.

2. The method of claim 1, wherein the reallocating of the at least a portion of the mobile system resources comprises allocating at least one communication resource from at least one adjacent cell to the at least one cell.

3. The method of claim 1, wherein the reallocating of the at least a portion of the mobile system resources comprises redefining a cell type of the at least one cell.

4. The method of claim 3, wherein the cell type is one of a standard spot cell, a micro cell, or a regional cell.

5. The method of claim 3, wherein the cell type comprises at least one of cells of a same size and cells of different sizes.

6. The method of claim 1, wherein the reallocating of the at least a portion of the mobile system resources comprises allocating greater gain over temperature (G/T) to the at least one cell.

7. The method of claim 1, wherein the capacity threshold for the at least one cell is related to available frequency bandwidth of the at least one cell.

8. The method of claim 1, wherein the capacity threshold for the at least one cell is predetermined.

9. The method of claim 1, wherein the at least one cell may be one of a regular shape or an irregular shape,

wherein the regular shape comprises at least one of sides of identical lengths or angles of identical sizes, and

wherein the irregular shape comprises at least one of sides of different lengths or angles of different sizes.

10. The method of claim 1, wherein the reallocating of the at least a portion of the mobile system resources occurs without a handover event.

15. The method of claim 1, wherein the communication demand is related to at least one of frequency bandwidth, data rate, or power.

16. The method of claim 1, wherein when there are at least two of the adjacent cells that are redefined, each of the adjacent cells are enlarged by a same amount of size to cover the at least a portion of the at least one cell.

17. The method of claim 1, wherein when there are at least two of the adjacent cells that are redefined, at least two of the adjacent cells that are redefined are enlarged by a different amount of size to cover the at least a portion of the at least one cell.

18. The method of claim 1, wherein the reallocating of the at least a portion of the mobile system resources further comprises allocating at least one carrier from the at least one adjacent cell to the at least one cell.

11. A system for self-optimizing mobile system resources, the system comprising:

at least one processor to determine a communication demand for at least one cell in a network, wherein the at least one cell is a polygon shape and at least one adjacent cell to the at least one cell is a polygon shape;

to determine that the communication demand for the at least one cell exceeds a capacity threshold for the at least one cell; and

to reallocate, based on the determining of the communication demand for the at least one cell exceeds the capacity threshold for the at least one cell, at least a portion of the mobile system resources,

wherein the at least one processor is to reallocate the at least a portion of the mobile system resources by redefining at least one vertex of the at least one adjacent cell to enlarge the at least one adjacent cell, according to how much the communication demand exceeds the capacity threshold for the at least one cell, such that at least a portion of the at least one adjacent cell covers at least a portion of the at least one cell and such that the respective communication demand for the at least one cell and the at least one adjacent cell is met;

wherein the at least one processor is to reallocate the at least a portion of the mobile system resources by allocating greater effective isotropic radiation power (EIRP) to the at least one cell.

12. The system of claim 11, wherein when the at least one processor is to reallocate the at least a portion of the mobile system resources, the at least one processor is to allocate at least one communication resource from at least one adjacent cell to the at least one cell.

13. The system of claim 11, wherein when the at least one processor is to reallocate the at least a portion of the mobile system resources, the at least one processor is to redefine a cell type of the at least one cell.

14. The system of claim 13, wherein the cell type is one of a standard spot cell, a micro cell, or a regional cell.
