A process for determining neighbor tier relationships between cells in a wireless telecommunications network includes establishing a plurality of cell points, each cell point representing a cell of a plurality of cells in the wireless telecommunications network, forming a plurality of triangles, the vertices of each triangle of the plurality of triangles corresponding to respective cell points of the plurality of cell points, removing edges from a portion of the plurality of triangles, determining neighbor tier relationships between the plurality of cells using remaining triangle edges between the plurality of cell points, storing the neighbor tier relationships in a first memory, and using the neighbor tier relationships for handovers between the plurality of cells.
