LTE CSFB with SIB (rel09)

[wolverine]

Hello,

Does anyone have practical experience of LTE CSFB with SIBs of the target WCDMA cells included in the RRC Connection Release?

If so, which SIBs are included? Is it all, including SIB11? Or a subset?

If you have any logs can you share them, or at least copy paste the contents of the LTE RRC Connection Release that includes the SIB info?

thanks

Hi! Rohde-Schwarz says "In 3GPP release 9, the redirection information was further enhanced in the RRCConnectionRelease message to improve the CSFB mechanism and further
reduce call setup delays. The RRC connection release with redirection now also
includes system information of one or more GERAN or UTRAN cells on the
redirected carrier frequency. The system information of the cell according to GERAN or
UTRAN protocols is provided in a System Information Container within the
RRCConnectionRelease message. For UMTS target cells, for example, this includes
the Master Information Block and System Information Block types 1, 3, 5, 7, and
optionally 11, 11bis and 12 and scheduling blocks".

I've been doing some tests regarding CSFB. Maybe next week i can get you some TEMS logs for you to check out!

That would be really nice, thanks
