GRADUAL FREQUENCY PLAN REVISION METHODOLOGY
Utilizing a sequential local search optimization algorithm (30), a determination is made of the cell/transceiver retunes (32) needed to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system. Each of the individual cell/transceiver retunes is evaluated (34) to determine if it meets certain save criteria, and if so, is saved as an intermediate frequency plan (74) in a sequence of saved intermediate frequency plans necessary to migrate from the current frequency plan to the determined near-optimal frequency plan. A sequential implementation (36) of these intermediate frequency plan revisions is then made to gradually reach, in a known and controlled manner, the better frequency plan.
