Dear Experts,
We face an issue related Call setup time. Before in our 4G network CSFB was performing by Redirection. We activated CSFB PS Handover feature in one cluster for trial.
After feature activated call setup time increased fom 6 s. to 9 s.
I analysed the logs and everything looks normal except UE perform more measurements. In CSFB redirection was performing 1 or 2 times 'UE Capability Enquiry' but in PS Handover it happened 4-5 times.
Note: 4G network vendor N// but 3G network vendor E//
Please support us.
Thanks in advance.
