What parameter can I use to reduce the CSFB call setup time


Hi all,

for CSFB call setup time , what is the parameter to reduce time?


Are you using flash CSFB?


How do I find out whether we are using flash CSFB or not from L3 message?


You will find Target Cell PCI and redirection FREQ to UTRAN services from RRC connection release msg from eNB.

Better yet, check which feature you are using from U2000


I am not yet using flash CSFB


Enable IdleCsfbRedirectOptSwitch on ENB level & also enable DMCR from 3G side (DeferMcReadInd) on cell level


OK. Let me try that.
