Patent ID: 8213942

Claim:
A method for cognitive neighbor selection in 4 g networks including a plurality of base stations comprising the steps of: a) obtaining, by a SON server, information about RSSI distributions, CINR distributions and serving areas of base stations; b) calculating a first metric and a second metric for each existing base station ( 403 ) with serving area overlapping a new BS new base station ( 404 ) serving area ( 406 ), wherein the first metric represents the portion of the existing base station's serving area that does not overlap with the serving area of the new base station and the second metric represents the portion of the border of the serving area of the new base station that lies within the serving area of the existing base station; c) adding said metrics together, and selecting a neighboring base station with the highest Sum i and adding said new base station to a neighbor list; d) after updating the neighbor list with the new base station, calculating a vicinity area ( 502 ) and a new border curve ( 505 ) by removing the contributions of all neighboring base stations within the vicinity area while disregarding all areas of overlap ( 408 ) with the BS new ; e) repeating said process until Sum i drops below a preconfigured threshold Sum max .
