Abstract
In a method for allocating channel for reducing hard handoff in CDMA system, which is divided all service area by a plurality of cells and allocates channel at each cell, cell is divided with a plurality of concentric circle regions, first region is allocated channel not allocated with a neighbor cell, third region is allocated channel allocated with a neighbor cell, and second region is allocated channel capable of allocating at both the neighbor cell and the cell.
