Abstract
The present invention provides a method of assigning cell identifiers to a plurality of cells. The method includes detecting cells within a selected distance from a first cell in the plurality of cells. The distance is selected to encompass portions of neighbor cells of the first cell and neighbor-of-neighbor cells of the first cell. The method also includes assigning a first cell identifier to the first cell. The first cell identifier is different than cell identifiers assigned to the cells detected within the selected distance from the first cell.
Claims20
A method of assigning cell identifiers to a plurality of cells, the method comprising:
- selecting, using a server, a distance from a first cell in the plurality of cells based on a maximum allowed path loss associated with the first cell;
- detecting, using the server, cells within the selected distance from the first cell, the distance being selected to encompass portions of neighbor cells of the first cell and neighbor-of-neighbor cells of the first cell;
- and
- assigning, using the server, a first cell identifier to the first cell, the first cell identifier being different than cell identifiers assigned to the cells detected within the selected distance from the first cell.

A method of assigning cell identifiers to a plurality of cells, the method comprising:
- detecting, using a server, cells within a selected distance from a first cell in the plurality of cells, the distance being selected to encompass portions of neighbor cells of the first cell and neighbor-of-neighbor cells of the first cell, wherein detecting cells within the selected distance from the first cell comprises:
- determining, using the server, a plurality of physical locations of the plurality of cells;
- determining, using the server, a netting circle around the first cell using the selected distance;
- and
- selecting, using the server, at least one second cell when the physical location of said at least one second cell is within the netting circle;
- and
- assigning, using the server, a first cell identifier to the first cell, the first cell identifier being different than cell identifiers assigned to the cells detected within the selected distance from the first cell.
