Hi experts ,

Fast return to LTE after supplementary csfb is taking more than 10 sec whereas after cs call it’s taking only 1 sec .
Smart LTE layering is enabled with all services and all triggers. Any other parameter I am missing here .

In log analysis I can see after ussd signalling end msc sending of end of csfb message but RNC not sending rrc release with redirect and after that ue continue with Rau and lac update

First of all make sure that you define all ADJLs with desired frequencies.

Then modify this PRFIL 002:1916 RN60_MAINT_41

The best value is 0111H in case of Smart Layering.

This can be done using the following comman

Set app-configuration parameter class 2 number 1916 value 0111
