관련 LinkLTE Architecture and FEATURES This feature avoids reading SIBs with information that can be received at another occasion. Such information is included in SIB11 and 12. The SIB 11 includes measurement control and neighbouring cell list. As soon as a call is setup in Ericsson WCDMA, intra frequency measurements are started and the information in SIB11 information is retransmitted to the UE...

§ 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.) –..

Direction: E-UTRAN => UESignalling Radio Bearer: SRB1RLC Mode: AMLogical Channel: DCCHTransport Channel: DL-SCH The RRC CONNECTION RELEASE message is used to command the release of an RRC connection. E-UTRAN initiates the RRC connection release procedure to an UE in RRC_CONNECTED state. The RRC CONNECTION RELEASE procedure with redirection information can also be used for CS-fallback to GERAN or..
