Abstract
A method for configuring color codes in a cellular telephone network is disclosed. The method includes calculating a distance between all possible color codes to be assigned to each of the cells in the network, assigning a first code to a first base station, determining a second code corresponding to a maximum calculated distance from the first code, and assigning subsequent codes to adjacent cells as determined by the maximum available distance between the two neighboring cells' codes to help minimize cross talk and channel interference on the cellular network.
Claims20
A method for configuring color codes to base-stations of a Mobile Telephone Switching Office (MSO) of a cellular telephone network, the method comprising:
- assigning a first code of a plurality of codes to a first base-station of a plurality of base-stations;
- calculating a distance between the first code and a second code of the plurality of codes;
- determining a maximum calculated distance from the first code to a plurality of remaining codes of the plurality of codes;
- and
- assigning the second code to a second base-station of the first MSO when the calculated distance between the first code and the second code matches the maximum calculated distance from the first code;
- wherein a wireless coverage cell of the second base-station is substantially adjacent to a wireless coverage cell of the first base-station.
A method for configuring color codes of a cellular telephone network, the method comprising:
- assigning, randomly, the first code to a first base-station within the MSO and the second code to a second base-station within the MSO;
- calculating a distance metric for a distance between the first base-station and the second base-station.
A method for minimizing cross channel interference in a wireless telephone network, the method comprising:
- configuring a plurality color codes within a first Mobile Switching Office (MSO), wherein the step of configuring comprises:
- assigning the first code to a first base-station within the first MSO;
- configuring the plurality color codes within a second MSO, wherein the step of configuring comprises:
- assigning the second codes to a second base-stations within the second MSO;
- wherein the second code is assigned to the second base-station such that, if a cell of the second base-station is substantially adjacent to a cell of the first base-station within the first MSO, the second code is assigned to be a maximum available calculated distance from the first code, said maximum available distant being measure in four dimensional space.
