A highly defined smartphone etc can be offered services by a range of mobile network access systems e.g. GSM, GERAN, UTRAN, e-UTRAN etc when switched ON and actively in use or in idle mode. Access system information for LTE and UMTS are mapped in System Information Blocks (SIBs). When conducting ICCSA test measurement it is useful to identify which broadcasted SIBs contain data to help understand the survey results. Knowing the content allocated to SIBs can assist enormously in interpretation and when considering the propositions highlighted in the previous discussion thread - http://cellsiteanalysis.blogspot.co.uk/2014/08/csa-site-survey-method4cell-types.html
Below are commonly referred to LTE/UMTS SIBs. GSM and GERAN data are mapped to System Information Types that will be given in the next discsssion.
LTE System Information Blocks
***************************
SIB 1 contains PLMN identity, tracking area code, and CI of the broadcasting cell. Q-RxLevMin minimumRSRP threshold that a broadcasting cell should be measured before initial cell selection, and later for random access performed by UE. SIB Mapping Info included to inform the UE which SIBs are transmitted and how they are scheduled.
SIB 2 contains timers and constants, access barring information, UL frequency information, and UL bandwidth information.
SIB 3 contains parameters for the cell reselection procedure.
SIB 4 contains neighbour cell information for intra-frequency cell reselection.
SIB 5 contains information for interfrequency cell reselection.
SIB 6 contains information for inter-RAT cell reselection to the UTRAN.
SIB 7 contains information for inter-RAT cell reselection to the GERAN.
SIB 8 contains information for inter-RAT cell reselection to CDMA2000.
SIB 9 is used to broadcast the home eNB name (HNB name).
SIB 10 and SIB 11 can be used to broadcast warning information to subscribers (e.g. tsunami warnings).
SIB 12 assigned for Commercial Mobile Alerting System (CMAS) information usage
