eRAN FDD Feature document eRAN15.1
below are the condition for delete redundant neighbor relationships. 
please help me to know about first condition :
  • The total number of handover attempts from the local cell to all its neighboring E-UTRAN cells is greater than or equal to the ANR.StatisticNumForNRTDel parameter value.
rather than  greater than or equal to the ANR.StatisticNumForNRTDel parameter value. it should be less than equal???. 

Removal of redundant neighbor relationships

This removal function takes effect on intra-RAT neighbor relationships only when the local cell is configured with more than the minimum number of neighboring cells. The minimum number of intra-frequency neighboring cells is specified by the NCellParaCfg.NcellNumForAnr parameter. The minimum number of inter-frequency neighboring cells is specified by the EutranInterNFreq.NcellNumForAnr parameter.

A neighbor relationship is redundant if the following conditions are met within each of ANR.StatPeriodCoeff consecutive measurement periods defined by ANR.StatisticPeriodForNRTDel:
  • The total number of handover attempts from the local cell to all its neighboring E-UTRAN cells is greater than or equal to the ANR.StatisticNumForNRTDel parameter value.
  • The number of handover attempts from the local cell to this neighboring cell is 0.
  • The neighboring cell is not configured as an SCell for any UE in the local cell.

This is a good function
