Bad Quality-Case-2
Page 7
Causes: Idle mode that area serving by DHK0719W but due to missing NBR that point serving by DHK0474W.
For that reason Ec/Io is poor.
Solution: Need to create NBR with detect cell.

Missing Neighbors-Case-2
Page 9
Causes: Due to missing NBR call droop occurred. In detected set found better RSCP & Ec/Io but handover not
perform.
Solution: Need to create NBR with detect cell.

Dropped Call-Case-1
Page 10
Causes: Voice call transferred to 2nd carrier due to bad RSCP & Ec/Io. Found better RSCP & Ec/Io in
detected set, Handover not perform due to NB Issue.
Solution: Need to create NBR with detect cell.

As per log file analysis of that polluted area of cluster 6C we have deleted
and add some NBR cells as to make a dominant server in that area to
reduce Pilot Pollution. Followings are the NBR recommendations which
executed in RNC.
