§ R9 Redirection with SIB – If the eNB receives a CSFB indicator, it sends the UE an RRC Release message containing the frequency of a target UTRAN, IDs of multiple target cells, and SI for the target cells. – This helps the UE to quickly access the target UTRAN and reduces the delay resulting from redirection. – The UE then can directly initiate CS services. (It might reduce total 1 ~ 2 Sec.) –..
