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.

Claims

1. A non-transitory computer-readable 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 a defined type of external interference determined to be impacting operation of the first base station device comprises interference from a device that operates outside of a communication system within which the first base station device operates, wherein the defined type of external interference comprises noise from the device for a time during which the device that operates outside of the communication system is powered on, and wherein the device is distinct from the first base station device; and

modifying a first service area of the first base station device based on an outcome of determining whether the uplink noise comprises the defined type of external interference.

2. The non-transitory computer-readable medium of claim 1, wherein the modifying comprises decreasing a first size of the first service area to a second size of a second service area smaller than the first size by removing a portion of an imbalance region in the first service area.

3. The non-transitory computer-readable medium of claim 2, wherein the imbalance region is determined to be located at a region between an uplink service area and a downlink service area.

4. The non-transitory computer-readable medium of claim 1, wherein the modifying comprises:

reducing an amount of downlink power transmitted from the first base station device from a first downlink power to a second downlink power.

5. The non-transitory computer-readable medium of claim 4, wherein the operations further comprise:

as a result of the first downlink power being reduced to the second downlink power, facilitating transfer, of a mobile device in the imbalance region, to a cell device associated with a second base station device.

6. The non-transitory computer-readable medium of claim 1, wherein the modifying comprises:

changing a re-selection parameter associated with changing a transmission range of the first base station device.

7. The non-transitory computer-readable medium of claim 1, wherein a source of the external interference by the device comprises an analog signal.

8. A method, comprising:

detecting, by a device comprising a processor, an uplink noise on an uplink channel of a first base station device, wherein a defined type of external interference determined to be impacting operation of the first base station device comprises foreign interference from a device that operates outside of a communication system within which the first base station device operates, wherein the external interference is determined to be the foreign interference based on a determination that the external interference has an amplitude greater than a defined threshold and is non-intermittent over a duration of time that the device that operates outside of the communication system is powered on, and wherein the device is different from the first base station device; and

modifying, by the device, a first service area of the first base station device based on a result of determining whether the uplink noise comprises the defined type of external interference.

9. The method of claim 8, wherein the defined threshold is adjustable based on current or historical mobile device interference levels, and wherein the modifying comprises reducing a first size of the first service area to a second size of a second service area smaller than the first size by removing a portion of an imbalance region in the first service area.

10. The method of claim 9, wherein the imbalance region is determined to be located at a region between an uplink service area and a downlink service area.

11. The method of claim 9, wherein the modifying comprises:

reducing an amount of downlink power transmitted from the first base station device from a first downlink power to a second downlink power.

12. The method of claim 11, further comprising:

as a result of the first downlink power being reduced to the second downlink power, facilitating transfer, by the device, of a mobile device in the imbalance region, to a cell device associated with a second base station device.

13. The method of claim 9, wherein the modifying comprises:

adjusting a re-selection parameter associated with reducing a transmission range of the first base station device.

14. The method of claim 8, wherein the defined threshold varies based on time of day, day of month or month of year, and wherein a source of the external interference by the device comprises an analog signal broadcast by the device.

15. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

determining a presence of an uplink noise on an uplink channel of a first base station device, wherein a defined type of external interference determined to be impacting operation of the first base station device comprises a defined type of interference from a device that operates outside of a communication system within which the first base station device operates, wherein the defined type of interference is identified based on a determination that the interference during which the device that operates outside of the communication system is powered on, and wherein the device is not the first base station device; and

modifying a first service area of the first base station device based on determining that the uplink noise comprises the defined type of external interference, wherein the modifying comprises reducing a first size of the first service area to a second size of a second service area smaller than the first size by removing a portion of an imbalance region in the first service area.
