Disclosed is a method for optimizing hard handoffs, e.g., between Mobile Switching Centers in a CDMA network. In the method, preliminary conditions for a hard handoff test are first set up. Idle handoffs are then performed in a hard handoff area, log data for the idle handoffs is analyzed and adjustments to communication equipment are made accordingly. Next, hard handoff tests are conducted in a traffic state in the hard handoff area. Log data of the hard handoff tests are analyzed and further adjustments to communication equipment are made if hard handoff performance during the hard handoff tests is determined to be unsatisfactory. A final hard handoff confirmation test is then performed in the hard handoff area following the latter communication equipment adjustments.
