Abstract

Compensation is provided for foreign interference within a cell. Uplink (UL) noise on an UL channel to a first base station (BS) device is detected. Whether the UL noise includes interference is determined. Interference can include any device other than a mobile device configured to communicate with a BS device associated with a cell. The first service area of the BS device can be modified, e.g., scaled based on determining that the UL noise includes interference. Scaling can include reducing the first service area to a second service area that does not include an imbalance region in the first service area caused by the foreign interference. Scaling can be effected by reducing the amount of downlink power from the first BS device, or by adjusting a re-selection parameter associated with reducing the range of the BS device.

First claim

What is claimed is:

1. A method, comprising:
detecting, by a system comprising a processor, an uplink noise on an uplink channel of a first base station device, wherein foreign interference determined to be affecting the first base station device comprises interference from a device that operates on a first communication frequency channel, which is distinct from a second communication frequency channel on which the first base station device operates; and
modifying, by the system, a first service area of the first base station device based on determining whether the uplink noise comprises the foreign interference, wherein the modifying comprises reducing the first service area to a second service area smaller than the first service area by excluding a portion of an imbalance region in the first service area.

2. The method of claim 1 , wherein the modifying comprises:
reducing an amount of downlink power from the first base station device from a first downlink power to a second downlink power, and wherein the imbalance region is determined to be located at a gap region between an uplink service area and a downlink service area.

3. The method of claim 2 , further comprising:
facilitating, by the system, transfer, of a mobile device in the imbalance region, to a cell device associated with a second base station device.

4. The method of claim 3 , wherein the facilitating is performed by concurrently with the reducing the amount of downlink power from the first base station device.

5. The method of claim 2 , wherein the reducing the amount of downlink power comprises reducing the amount based on a difference by which an average value of the uplink noise is greater than a reference value.

6. The method of claim 1 , further comprising:
determining, by the system, that the uplink noise fails to comprise the foreign interference.

7. The method of claim 1 , wherein a source of the interference from the device comprises an analog signal broadcast by the device.

8. The method of claim 1 , wherein the modifying comprises:
adjusting a re-selection parameter associated with reducing a communication range of the first base station device, resulting in an adjusted re-selection parameter.

9. The method of claim 8 , further comprising:
facilitating, by the system, re-selection, from a first cell device associated with a first base station device to a second cell device associated with a second base station device, of an idle mobile device in the imbalance region based on the adjusted re-selection parameter.

10. The method of claim 8 , wherein the re-selection parameter is a first re-selection parameter, wherein the communication range is a first communication range, and further comprising:
adjusting, by the system, a second re-selection parameter associated with reducing a second communication range of a second cell device for the second base station device, wherein the second base station device neighbors the first base station device, and wherein the second re-selection parameter is adjusted by an amount determined to prevent re-selection of a first cell device for the first base station device by the idle mobile device.

11. The method of claim 8 , further comprising:
determining, by the system, that the uplink noise no longer comprises the foreign interference; and
re-adjusting, by the system, the adjusted re-selection parameter to the re-selection parameter based on the determining that the uplink noise no longer comprises the foreign interference.

12. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
detecting an uplink noise on an uplink channel of a first base station device, wherein interference determined to be affecting a performance of the first base station device comprises device interference from a device that operates within a first communication frequency channel, which is distinct from a second communication frequency channel within which the first base station device operates; and
changing a first service area of the first base station device based on determining whether the uplink noise comprises the interference, wherein the changing comprises reducing the first service area to a second service area by excluding a portion of an imbalance region in the first service area, and wherein the imbalance region is determined to be located at a gap area between an uplink service area and a downlink service area.

13. The system of claim 12 , wherein the changing comprises:
reducing an amount of downlink power from the first base station device from a first downlink power to a second downlink power.

14. The system of claim 13 , wherein the operations further comprise:
facilitating transfer, of a mobile device in the imbalance region, to a cell device associated with a second base station device.

15. The system of claim 14 , wherein the facilitating the transfer is performed as a result of the reducing the amount of downlink power from the first base station device from the first downlink power to the second downlink power.

16. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
detecting an uplink noise on an uplink channel of a first base station device, wherein interference determined to be affecting a performance of the first base station device comprises device interference from a device that operates within a first communication frequency channel, which is distinct from a second communication frequency channel within which the first base station device operates; and
changing a first service area of the first base station device based on determining whether the uplink noise comprises the interference, wherein the changing comprises reducing the first service area to a second service area by excluding a portion of an imbalance region in the first service area, and wherein the imbalance region is determined to be located at a gap area between an uplink service area and a downlink service area.

17. The non-transitory machine-readable storage medium of claim 16 , wherein the changing comprises:
reducing an amount of downlink power from the first base station device from a first downlink power to a second downlink power.

18. The non-transitory machine-readable storage medium of claim 17 , wherein the operations further comprise:
facilitating transfer, of a mobile device in the imbalance region, to a cell device associated with a second base station device.

19. The non-transitory machine-readable storage medium of claim 18 , wherein the facilitating the transfer is performed as a result of the reducing the amount of downlink power from the first base station device from the first downlink power to the second downlink power.

20. The non-transitory machine-readable storage medium of claim 16 , wherein the changing comprises:
reducing an amount of downlink power from the first base station device from a first downlink power to a second downlink power, and wherein the imbalance region is determined to be located at a gap region between an uplink service area and a downlink service area.
