Thanks a lot for your insightful analysis, its much clearer now, i already had an idea but just wanted to make sure 🙂
P.S i would also like to cite an observation regarding increase in BTS queue length before Christmas and new year night , for congestion relief it helped but it impact the global indicator for CDR .
I believe the degradation was owing to less inc HO on congested cells which in turn when taken into the formula for glocal CDR degraded the KPI , a trial reversal for one BSC resulted in instant improvement on the that BSC wrt CDR.
Correct me if i am wrong here.
Thanks again
🙂
