Abstract

An example method includes receiving data from a femto access point; evaluating resources being used by a macro network in which the femto access point resides; determining whether the femto access point is operating in a constrained bandwidth mode; and reserving particular resources for the femto access point to use for its communications, where the particular resource is allocated from available resources within the macro network. In a more particular embodiment, where those resources refer to spectrum resources, the method includes allocating spectrum resources between femto and macrocellular systems. In other embodiments, the method includes identifying a total throughput associated with the femto access point and one or more macro network cells, where a change in reserving particular frequencies is executed based on determining the total throughput being higher than a current throughput. The data from the femto access point can include path loss data and geolocation data.

Claims (40)

1. A method, comprising:

receiving data from a femto access point;

evaluating resources being used by a macro network in which the femto access point resides;

determining whether the femto access point is operating in a constrained bandwidth mode; and

reserving a particular resource for the femto access point to use for its communications, wherein the particular resource is allocated from available resources within the macro network.

2. The method of claim 1 , further comprising:

identifying a total throughput associated with the femto access point and one or more macro network cells, wherein a change in reserving the particular resource is executed based on determining the total throughput being higher than a current throughput.

3. The method of claim 1 , wherein the data from the femto access point includes geolocation data and path loss data between the femto access point and the macro network, and wherein the femto access point is mapped to a fractional frequency range band.

4. The method of claim 1 , wherein geolocation data is used in determining how to allocate the available resources in the macro network to one or more femto access points.

5. The method of claim 1 , wherein if a number of resource constrained requests from one or more femto cells pass a predetermined threshold, self organizing network operations are triggered to shift a portion of the resources from the macro network to the one or more femto cells.

6. The method of claim 1 , wherein cell channel power is measured during idle periods in order to determine if the femto access point is in proximity to a neighboring femto access point or the macro network using the same resources, wherein if the cell channel power passes a given threshold, a signal is sent to a femto management element.

7. The method of claim 1 , further comprising:

establishing a message exchange between multiple femto cells in close proximity to each other, wherein the message exchange is used to identify resource utilization between the multiple femto cells.

8. The method of claim 1 , further comprising:

allocating spectrum resources corresponding to sub-carrier allocations between the femto access point and the macro network.

9. Logic encoded in one or more tangible media that includes code for execution and when executed by a processor operable to perform operations comprising:

receiving data from a femto access point;

evaluating resources being used by a macro network in which the femto access point resides;

determining whether the femto access point is operating in a constrained bandwidth mode; and

reserving a particular resource for the femto access point to use for its communications, wherein the particular resource is allocated from available resources within the macro network.

10. The logic of claim 9 , the operations further comprising:

identifying a total throughput associated with the femto access point and one or more macro network cells, wherein a change in reserving the particular resource is executed based on determining the total throughput being higher than a current throughput.

11. The logic of claim 9 , wherein geolocation data is used in determining how to allocate the available resources in the macro network to one or more femto access points.

12. The logic of claim 9 , wherein if a number of resource constrained requests from one or more femto cells pass a predetermined threshold, self organizing network operations are triggered to shift a portion of the resources from the macro network to the one or more femto cells.

13. The logic of claim 9 , wherein cell channel power is measured during idle periods in order to determine if the femto access point is in proximity to a neighboring femto access point or the macro network using the same resources, wherein if the cell channel power passes a given threshold, a signal is sent to a femto management element.

14. An apparatus, comprising:

a memory element configured to store data,

a processor operable to execute instructions associated with the data, and

a coordination module configured to interface with the processor in order to:

receive data from a femto access point;

evaluate resources being used by a macro network in which the femto access point resides;

determine whether the femto access point is operating in a constrained bandwidth mode; and

reserve a particular resource for the femto access point to use for its communications, wherein the particular resource is allocated from available resources within the macro network.

15. The apparatus of claim 14 , wherein the coordination module is further configured to:

identify a total throughput associated with the femto access point and one or more macro network cells, wherein a change in reserving the particular resource is executed based on determining the total throughput being higher than a current throughput.

16. The apparatus of claim 14 , wherein the data from the femto access point includes geolocation data and path loss data between the femto access point and the macro network, and wherein the femto access point is mapped to a fractional frequency range band.

17. The apparatus of claim 14 , wherein geolocation data is used in determining how to allocate the available resources in the macro network to one or more femto access points.

18. The apparatus of claim 14 , wherein if a number of resource constrained requests from one or more femto cells pass a predetermined threshold, self organizing network operations are triggered to shift a portion of the resources from the macro network to the one or more femto cells.

19. The apparatus of claim 14 , wherein the femto access point includes a measurement and reporting module configured to generate the data to be sent to a femto management element.

20. The apparatus of claim 14 , wherein a message exchange is established between multiple femto cells in close proximity to each other, wherein the message exchange is used to identify resource utilization between the multiple femto cells.
