Dear All

hope these documents are useful

Try to experiment with radio options, such as Base Band Hopping and Handover on SDCCH
1. Turn on Base Band Hopping in all the cell with the number of TRX greater than 1 (this can reduce SDCDR and CDR)
2. Handover on SDCCH leads to an increase SDCDR, try to turn off the option and watch the statistics.

Hi and Thanks for you docs !!

Have 2 questions :
- I tried to activate Call Re-establishement with NSN, but I have no impact at all on drop call rate. You have any experience with that?
- I just read in the presentation you sent that in Dualband system, clocks should be synchronized. How to do that, or how to verify it?
I have NSN here, so if somebdy could help me, would be great !

THanks again for sharing !

Hi：

Call Re-establishement is useless for CDR but waste of resources
