Abstract
A frequency plan revision proposal is evaluated to determine whether it is compatible with the current cell configuration by insuring that sufficient frequencies having appropriate operating modes are available for assignment to meet the traffic and control channel requirements and availability of the included cell transceivers. A record is kept of previously approved proposals resulting in a revision to the frequency plan assignment. A determination is then made as to whether the current proposal if implemented would have an adverse effect on the network in view of the previously approved proposals maintained by the record. An adverse effect is found when: a sub-frequency group/frequency dropped and/or added by the proposal at issue matches or is adjacent to a sub-frequency group/frequency dropped and/or added in the record of the previously approved proposals; and the distance between the cell of the proposal at issue and the cell of the previously approved proposal in the record are within a certain threshold distance of each other.
