Patent ID: 7920870

Claim:
A base station controller for adaptively configuring the structure of a cell served by said base station controller, said cell having a plurality of mobile stations located therein and a base transceiver station associated therewith, said base transceiver station having at least two carrier frequencies associated therewith, said base station controller comprising: measurement logic adapted to determine a respective distance of each of said mobile stations involved in a call connection within said cell from said base transceiver station; first comparison logic adapted to compare each said respective distance to a distance threshold to determine a number of said mobile stations having said respective distance less than or equal to said distance threshold; second comparison logic adapted to perform a comparison of said number to a channel threshold; and configuration logic adapted to switch between an overlaid/underlaid sub-cell structure having at least one of said at least two carrier frequencies serving only a portion of said cell and a normal cell structure having all of said at least two carrier frequencies serving the entire area of said cell based on the results of said comparison.
