Abstract
A method in a cellular telecommunications network for optimizing a current hysteresis value utilized to define a handoff border between a present cell and a neighbor cell. Pairs of signal strength (SS) measurements are collected from a plurality of mobile stations operating near the handoff border. Each SS measurement pair includes an SS measurement from the present cell and an SS measurement from the neighbor cell. A midpoint SS is then calculated by determining an average SS measurement from the present cell, an average SS measurement from the neighbor cell, and an overall average of the average SS measurement from the present cell and the average SS measurement from the neighbor cell. The method then optimizes the handoff border by subtracting from the current hysteresis value, an amount approximately equal to the difference between the midpoint SS and the average SS measurement from the present cell.
