Consideration of historical MAHO measurements for frequency plan revision determinations

A frequency planning tool, comprising:

• storage for saving radio environment statistics data for determining frequency plan revisions, that data having been collected in each one of a plurality of separate recording periods;
• a reliability check process that identifies a portion of the stored radio environment statistics data collected in recording periods prior to a currently completed recording period that has not been adversely affected by a frequency plan revision implemented since the recording period when the radio environment statistics data was collected;
• and
• a frequency plan revision algorithm executed following a conclusion of each separate recording period that processes both the radio environment statistics data collected in the currently completed recording period and the portion of the stored data identified by the reliability check in order to determine a frequency plan revision for implementation.

A method, comprising the steps of:

• collecting radio environment statistics data for determining frequency plan revisions during a current one of a plurality of separate recording periods;
• filtering collected radio environment statistics data collected in previous recording periods to the current period to identify reliable data;
• and
• executing a frequency plan revision algorithm following a conclusion of the current recording period that evaluates both the data from the current recording period and the identified reliable data in order to determine a frequency plan revision for implementation.
