Hello,
when i do the calculation 1500/26000 = 5.8%, not 10%
so there is a mistake somewhere in your numbers 🙂
anyway, so let’s just say that after you redesign your LAC borders, the SDCCH ass fail radio rate have increased, but is still within acceptable range.
do you also notice an increase in SDCCH requests ? in SDCH duration average ? what about the Location update ratio ? I guess it also increased, if that cell is at the lac border?
DO you notice increase in SDCCH drop rate as well ?
Try to give me a complete picture of what changed in terms of QoS indicators after the cutover.
Once you answer, I might ask even more indicators 🙂
Sorry to ask to many details… IMO though, the sd fail is still OK 🙂 But never mind, we can continue the investigation.
