Live issues with CSFB (LTE)

[jbada]

Hi Forum,
I would like to open this thread in order to know some issues in live implementation for the feature CSFB for LTE. According my experience is important to take in consideration:

1. dimensioning of TA should be less or equal to LA
2. Need SGs interface configured
3. EPS Attached Type should be “Combined EPS/IMSI Attach”
4. Some delay to establish the voice call due the effect that the UE has to change to another technology.

Please appreciate your comments.

Thanks
