Abstract

Aspects of a method and system for dynamic adjustment of power, antenna direction and frequencies in a femtocell network are provided. In this regard, a communication system may comprise a plurality of femtocells, one or more base stations, and a femtocell management entity that coordinates operation of the plurality of femtocells. One or more parameters may be communicated from one of the plurality of femtocells and/or one or more base stations to the femtocell management entity. The femtocell management entity may be enabled to utilize the one or more parameters to determine configuration information for one of the plurality of femtocells and/or for one or more remaining ones of the plurality of femtocells. One of the plurality of femtocells may be enabled to receive the determined configuration information from the femtocell management entity. One of the plurality of femtocells may be configured utilizing the received determined configuration information.

Claims (70)

1. A method for a femtocell management entity, the method comprising:

receiving a directionality of antennas of one or more of a plurality of femtocells, base stations, and cellular enabled communication devices and one or more parameters from one of said plurality of femtocells, base stations, and cellular enabled communication devices,

determining configuration information utilizing said directionality of antennas and said one or more parameters; and

communicating configuration information to a femtocell,

wherein one or more of said receiving, determining, and communicating is executed by a processor.

2. The method according to claim 1 , wherein a registry is updated based on said received directionality of antennas and said one or more parameters.

3. The method according to claim 2 , wherein said registry comprises one or more of:

global navigation system satellite (GNSS) coordinates, an identification number, and a list of said one or more parameters for each of said plurality of femtocells within said communication system.

4. The method according to claim 1 , further comprising receiving said directionality of antennas and said one or more parameters from said femtocell.

5. The method according to claim 1 , further comprising:

determining new configuration information utilizing said directionality of antennas and said one or more parameters; and

communicating new configuration information to one or more of said plurality of femtocells.

6. The method according to claim 1 , wherein said one or more parameters comprises one or more of: signal to noise ratio (SNR), signal to interference noise ratio (SINR), carrier to noise ratio (CNR), carrier to interference noise ratio (CINR), receive signal strength indication (RSSI), potential interference, and power levels of said plurality of femtocells.

7. The method according to claim 1 , wherein said configuration information comprises one or more of: power levels, frequencies of operation, and said directionality of antennas of said one or more of said plurality of femtocells.

8. The method according to claim 1 , further comprising:

determining location information of said femtocell.

9. The method according to claim 1 , comprising receiving said one or more parameters via a wireless connection.

10. The method according to claim 9 , wherein said wireless connection comprises one or more of:

11. The method according to claim 1 , wherein one or more femtocells may function as a management entity.

12. A system comprising:

one or more processors for use in a femtocell management entity that coordinates operation of said femtocell management entity, wherein:

said one or more processors are configured to receive a directionality of antennas of one or more of a plurality of femtocells and one or more parameters from one of said plurality of femtocells;

said one or more processors are configured to determine configuration information utilizing said directionality of antennas and said one or more parameters; and

said one or more processors are configured to communicate configuration information to a femtocell.

13. The system according to claim 12 , wherein a registry is updated based on said received directionality of antennas and said one or more parameters.

14. The system according to claim 13 , wherein said registry comprises one or more of:

global navigation system satellite (GNSS) coordinates, an identification number, and a list of said one or more parameters for each of said plurality of femtocells within said communication system.

15. The system according to claim 12 , wherein said one or more processors are configured to receive said directionality of antennas and said one or more parameters from said femtocell.

16. The system according to claim 12 , wherein

said one or more processors are configured to determine new configuration information utilizing said directionality of antennas and said one or more parameters; and

said one or more processors are configured to communicate new configuration information to one or more of said plurality of femtocells.

17. The system according to claim 12 , wherein said one or more parameters comprises one or more of:
