Abstract

A method for a proxy base station includes analyzing current network parameters, determining parameters for the proxy base station based on the analyzed network parameters, and transmitting the determined parameters for the proxy base station to an actual base station of the network.

Claims

1. A computer-implemented method for establishing a proxy base station in a communications network, the method comprising:

analyzing current network parameters;

determining parameters for the proxy base station based on the analyzed network parameters; and

transmitting the determined parameters for the proxy base station to an actual base station of the network.

2. The method of claim 1, wherein the communications network is a Long Term Evolution (LTE) wireless network, and the parameters for the proxy base station are transmitted over an X2 interface.

3. The method of claim 1, wherein the determined parameters include a geographical location that is associated with the proxy base station.

4. The method of claim 3, wherein determining the geographical location comprises:

determining a geographical location of the actual base station; and

setting a geographical location associated with the proxy base station such that it is considered to be a mobility neighbor of the first base station by the first base station.

5. The method of claim 4, wherein the geographical location associated with the proxy base station is set to be the geographical location of the actual base station.

6. The method of claim 1, wherein analyzing current network parameters includes determining EUTRA Absolute Frequency Channel Number (EARFCN) and transmission bandwidth values for the actual base station, and determining parameters for the proxy base station includes setting EARFCN and transmission bandwidth values of the proxy base station to be the same as the actual base station.

7. The method of claim 1, wherein the determined parameters include a geographical location, a Physical Cell Identifier (PCI), an E-UTRAN Global Identifier (ECGI), a Type Allocation Code (TAC), a Public Land Mobile Network (PLMN) Identifier, and a plurality of Information Elements.

8. The method of claim 1, wherein transmitting the determined parameters includes transmitting a first set of parameters for a first type of base station to the actual base station, and transmitting a second set of parameters for a second type of base station to a second actual base station.

9. The method of claim 1, wherein determining parameters for the proxy base station includes determining first parameters and determining second parameters that are different from the first parameters, and

wherein transmitting the determined parameters includes transmitting the first parameters to a first actual base station and transmitting the second parameters to a second actual base station.

10. The method of claim 2, further comprising:

receiving High Interference Indicator (HII) information and Overload Indication (OI) information from the actual base station at the proxy base station.

11. The method of claim 2, further comprising:

receiving Relative Narrowband Transmit Power (RNTP) information from the actual base station at the proxy base station.

12. A communications system comprising:

a processor;

a memory;

a parameter analysis module that analyzes current network parameters;

a parameter determination module that that determines parameters for a proxy base station based on the analyzed network parameters; and

a transmitter that transmits the determined parameters for the proxy base station to an actual base station of the network.

13. The system of claim 12, wherein the communications system is a Long Term Evolution (LTE) wireless network, and the parameters for the proxy base station are transmitted over an X2 interface.

14. The system of claim 12, wherein the determined parameters include a geographical location that is associated with the proxy base station.

15. The system of claim 14, wherein the geographical location is determined by:

determining a geographical location of the actual base station; and

setting a geographical location associated with the proxy base station such that it is considered to be a mobility neighbor of the first base station by the first base station.

16. The system of claim 15, wherein the geographical location associated with the proxy base station is set to be the geographical location of the actual base station.

17. The system of claim 12, wherein the current network parameters are determined by:

determining EUTRA Absolute Frequency Channel Number (EARFCN) and transmission bandwidth values for the actual base station; and

determining parameters for the proxy base station includes setting EARFCN and transmission bandwidth values of the proxy base station to be the same as the actual base station.

18. The system of claim 12, wherein the determined parameters include a geographical location, a Physical Cell Identifier (PCI), an E-UTRAN Global Identifier (ECGI), a Type Allocation Code (TAC), a Public Land Mobile Network (PLMN) Identifier, and a plurality of Information Elements.

19. The system of claim 12, the determined parameters are transmitted by:

transmitting a first set of parameters for a first type of base station to the actual base station; and

transmitting a second set of parameters for a second type of base station to a second actual base station.
