In E-UTRAN, SIBs 6, 7, 8 carry information for IRAT cell
reselection to UTRAN, GERAN, and CDMA2000 systems respectively. SIB 1 and SIB 3
also carry IRAT related information.
SIB6 contains information for
IRAT cell reselection to UTRAN, such as:
In UTRAN, the IRAT related
information is broadcasted in SIBs 6, 18, 19, as well as SIBs 3 and 4. SIB 19
is new to 3GPP Release 8.
SIB7 contains information for
IRAT cell reselection to GERAN, such as:
In GSM/GERAN, system information
from second quarter is modified in 3GPP Release 8 to include LTE-related
SIB8 contains information for
IRAT cell reselection to eHRPD (evolved High Rate Packet Data, which is the
1xEV-DO Rev.A with the support of connectivity to Evolved Packet Core of LTE),
SIB9 contains a Home eNB name. The
home eNB is the femto-cell in the context of LTE, a small base station used in
residential area or by small businesses.
SIB10 is for an ETWS (Earthquake and
Tsunami Warning System) primary notification. ETWS is a public warning system.
The paging procedure is used to inform the ETWS capable UEs in RRC idle and RRC
connected modes to listen to SIB10 and SIB11.
SIB11 is for an ETWS secondary
Well explained. Thanks
