Grouping and ungrouping among omni-cells using PN-offset of one channel
 A method for grouping and ungrouping omni-cells in a mobile communications system using a common PN-offset in one channel so as to manage a plurality of cells in a manner similar to a method by which an omni-cell is managed using a unique PN offset. Cell grouping is performed by generating a common PN offset in each of the cells to be grouped by selecting an unused path in each channel of each cell, and then changing the unique PN offset of each of the cells to the common PN offset of the selected path.
