Abstract

Utilizing a three pass processing procedure, a frequency plan revision proposal is defined, verified, implemented and confirmed by a network operator. In a first pass (evaluation), interference and bit error rate measurements are evaluated and used to create one or more proposals. These proposals are evaluated to confirm compatibility with the current cell configuration, coordination with previous proposals, and assignment of frequencies. In a second pass (pre-update verification), more measurements are evaluated to confirm the first pass proposals. A single proposal for each selected cell is then chosen for implementation in a network update. In a third pass (post-update verification), the measurements are again evaluated to verify, following the update, that the implementation of the proposal had a positive effect on the network.
