Abstract

A communications base station is installed at a selected new location and the base station, prior to going “online” 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 online, 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 service in a wireless network, said method comprising:

calculating, at a first base station, a set of transmission parameters for a second base station, said transmission parameters calculated to achieve service criteria;

receiving, at said first base station, signals from said second base station corresponding to measurements made by said second base station, said measurements based on wireless communication between said second base station and a mobile station; and

transmitting, from said first base station, a command to said second base station, said command comprising an adjustment to be made by said second base station to achieve said criteria.

2. The method of claim 1 wherein said command comprises an adjustment of coverage area power level, frequency, or mode of operation.

3. The method of claim 2 wherein said command is dependent upon time of day or day of week.
