Abstract

A communications base station is installed at a selected new location and the base station, prior to going “on line” monitors the wireless traffic from other base stations within interference range of the new base station'"'"'s coverage area. The new base station also monitors the wireless traffic between mobile devices within its coverage area and these other base stations. Based upon these monitored conditions, as well as other known conditions, the new base station then determines the transmitting parameter configuration it should imply in order to achieve a desired optimization between capacity and coverage area. After the new base station is on line, a central control can monitor the entire network to determine if any additional changes are necessary and if so the new transceiver, or any other transceiver, can be instructed to monitor itself with respect to interference and to take corrective action to improve overall network coverage and capacity.

Claims

1. A method for optimizing a communication system base station for wireless communications at a particular location;

said method comprising;

monitoring wireless traffic from other base stations within interference range of the coverage area of said base station at said particular location, said base station wireless traffic monitoring performed by said base station at said particular location;

monitoring wireless traffic between mobile devices within said coverage area and said other base stations, said mobile device monitoring performed by said base station at said particular location; and

determining from said monitored base station traffic and from said monitored mobile wireless traffic the transmitting parameters to use at said base station at said particular location to achieve a desired optimization between capacity and coverage area with respect to said base station.

2. The method of claim 1 wherein said monitoring of base station traffic and said monitoring of said mobile device traffic is performed prior to said base station going online.

3. The method of claim 2 further comprises:

adjusting said base station to achieve said transceivers parameters prior to bringing said base station online.

4. The method of claim 3 wherein said transmitting parameters at selected from the list including;

frequencies, sub-frequencies, channels, carriers,

effective antenna tilt, azimuth, radiation patterns, power levels, polarization.

5. The method of claim 4 further comprising the step of:

from time to time adjusting said base station transmitting parameters to achieve a desired optimization suitable for the time of said adjustment based on said monitoring of said base station traffic and said monitoring of said mobile station traffic at a previous point in time.

6. The method of claim 3 wherein said base station from time to time repeats said monitoring, of determining and said adjustment steps.

7. The method of claim 1 wherein said monitoring of mobile wireless traffic comprises:

determining areas within said coverage area that should be specifically targeted for coverage from said base station.

8. The method of claim 7 wherein said determining comprises selecting areas where said monitored mobile wireless traffic is below a certain threshold.

9. The method of claim 1 further comprising:

at least one of said other base stations monitoring mobile wireless traffic within its respective coverage area and adjusting its transmitting parameters to achieve improved wireless capacity in the combined coverage areas served by said base stations.

10. The method of claim 9 wherein said monitoring by said other base stations is initiated from a control point for said combined coverage area.

11. A system for optimizing a communication system base station for wireless communications at a particular location;

said system comprising;

means operable prior to said particular location base station going online for monitoring wireless traffic from other base stations within interference range of the coverage area of said base station; and

transceiver;

means also operable prior to said particular location base station going online for monitoring wireless traffic between mobile devices within said coverage area and said other base stations, and

means for determining from said monitored base station traffic and from said monitored mobile wireless traffic the transmitting parameters to use at said particular location base station to achieve a desired optimization between capacity and coverage area with respect to said base station.

12. The system of claim 11 wherein said base station traffic monitoring means and said mobile device traffic monitoring means are performed from said particular locator base station.

13. The system of claim 12 further comprises:

means for adjusting said particular locator base station to achieve said transceivers parameters prior to bringing said particular locator base station online.

14. The system of claim 13 wherein said transmitting parameters at selected from the list including;

frequencies, sub-frequencies, channels, carriers,

effective antenna tilt, azimuth, radiation patterns, power levels, polarization.

15. The system of claim 13 wherein said mobile wireless traffic monitoring of mobile wireless traffic comprises:

means for determining areas within said coverage area that should be specifically targeted for coverage from said base station.

16. The system of claim 15 wherein said determining means comprises

means for selecting areas where said monitored mobile wireless traffic is below a certain threshold.

17. The system of claim 13 further comprising:

at least one of said other base stations comprising;

means for monitoring mobile wireless traffic within its respective coverage area; and

means for adjusting its transmitting parameters to achieve improved wireless capacity in the combined coverage areas served by said base stations.

18. The system of claim 17 wherein said monitoring means last-mentioned is initiated from a control point for said combined coverage area.
