Abstract
Provided is a system and method for optimizing the performance of the cellular network by maintaining status values concerning the cell and adjusting the conditions for handoff in response to the status values. The status values may include a pilot signal strength measurement for the second cell, a round trip delay measurement from the second cell to the mobile unit, an a designation of whether the second cell is current, removed, or most recently removed. With the status values, a determination can be made to remove the second cell from the mobile unit's Active Set if either the pilot signal strength for the second cell falls below a predetermined threshold or the round trip delay value exceeds a predetermined maximum.
