Abstract

Systems, methods, and apparatuses for centrally optimizing femtocells are presented herein. A scanning component can receive information from femtocells indicating respective operating conditions of the femtocells. Further, an optimization component can categorize the femtocells into groups based on the information, and direct a change of a parameter set of a group of the groups to a femtocell of the group. A method can include receiving, from femtocells, information associated with respective operating conditions of the femtocells; sorting the femtocells into groups based on the information; and directing a change of a parameter set that is associated with a group of the groups to a femtocell of the group. In an example, the method can further include directing a change of a parameter of a macrocell communicatively coupled to a femtocell of the femtocells.

Claims

1. A method, comprising:

receiving, by a system comprising a processor, information from femtocell devices representing operating conditions with respect to signals detected by the femtocell devices, wherein an operating condition of the operating conditions comprises a first number of mobile devices that have attempted to register with a first femtocell device of the femtocell devices and that have not been authorized to access the first femtocell device;

in response to the first number of mobile devices being determined to satisfy a defined condition with respect to a second number of mobile devices that have attempted to register with a second femtocell device of the femtocell devices and that have not been authorized to access the second femtocell device, assigning, by the system, the first femtocell device and the second femtocell device to a group of femtocell devices; and

in response to the assigning of the first femtocell device and the second femtocell device to the group of femtocell devices, directing, by the system, a change of a parameter to the group of femtocell devices.

2. The method of claim 1, wherein the assigning comprises sorting the femtocell devices into groups comprising the group of femtocell devices.

3. The method of claim 1, further comprising directing, by the system, a macrocell parameter change of a macrocell parameter of a macrocell device associated with the group of femtocell devices.

4. The method of claim 1, wherein the first femtocell device is associated with a first wireless communication environment and the second femtocell device is associated with a second wireless communication environment different than the first wireless communication environment.

5. The method of claim 1, wherein the directing comprises directing a power change of a transmission power to the group of femtocell devices.

6. A system, comprising:

a memory that stores executable instructions; and

a processor, coupled to the memory, that facilitates execution of the executable instructions to perform operations, comprising;

receiving, from femto cell devices, information representing operating conditions with respect to signals detected by the femtocell devices, wherein an operating condition of the operating conditions comprises a first number of mobile devices that have attempted to register with a first femtocell device of the femtocell devices and that have not been authorized to access the first femtocell device;

in response to the first number of mobile devices being determined to satisfy a defined condition with respect to a second number of mobile devices that have attempted to register with a second femtocell device of the femtocell devices and that have not been authorized to access the second femtocell device, categorizing the first femtocell device and the second femtocell device into a group of femtocell devices; and

in response to the categorizing of the first femtocell device and the second femtocell device into the group of femtocell devices, directing a change of a parameter to the group of femtocell devices.

7. The system of claim 6, wherein the information represents a result of a network scan that is associated with the femtocell devices.

8. The system of claim 7, wherein the result of the network scan is associated with a macrocell device corresponding to the femtocell devices.

9. The system of claim 6, wherein the information represents a strength of a signal that is detected by a femtocell device of the femtocell devices.

10. The system of claim 6, wherein the information represents a detected power that is associated with a communication channel.

11. The system of claim 6, wherein the information represents a received signal strength indicator that is associated with a signal that is received by a femtocell device of the femtocell devices.

12. The system of claim 6, wherein the information represents a level of interference of a signal that is detected by a femtocell device of the femtocell devices.

13. The system of claim 6, wherein the information represents a period of time associated with a use of a femtocell device of the femtocell devices.

14. The system of claim 6, wherein the parameter comprises a transmission power.

15. The system of claim 6, wherein the operations further comprise directing a handover change of a handover to a femtocell device of the group of femtocell devices.

16. The system of claim 6, wherein the operations further comprise directing a parameter change of an operating parameter of a macrocell device to the macrocell device based on the information.

17. The system of claim 6, wherein the first femtocell device is associated with a first wireless communication environment, and wherein the second femtocell device is associated with a second wireless communication environment different than the first wireless communication environment.

18. The system of claim 6, wherein the parameter comprises a wireless communication channel.

19. A computer-readable storage device comprising executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:

in response to receiving, from femtocell devices, information representing operating conditions of the femtocell devices with respect to signals detected by the femtocell devices, determining whether an operating condition of the operating conditions satisfies a defined condition with respect to a first amount of mobile devices that have attempted to register with a first femtocell device of the femtocell devices and that have not been authorized to access the first femtocell device, and with respect to a second amount of mobile devices that have attempted to register with a second femtocell device of the femtocell devices and that have not been authorized to access the second femtocell device;

in response to determining that the operating condition satisfies the defined condition with respect to the first amount of mobile devices that have attempted to register with the first femtocell device and that have not been authorized to access the first femtocell device, and with respect to the second amount of mobile devices that have attempted to register with the second femtocell device and that have not been authorized to access the second femtocell device, categorizing the first femtocell device and the second femtocell device into a group of femtocell devices; and

in response to the categorizing of the first femtocell device and the second femto cell device, directing, to the group of femtocell devices, a change of a parameter.

20. The computer-readable storage device of claim 19, wherein the categorizing comprises categorizing the first femtocell device and the second femtocell device into the group of femtocell devices based on a quality of a signal of the signals.
