Events and SIB

Pada umumnya event-event yang terjadi pada mobile communication dijabarkan pada tabel berikut :

Event Type	Description
Event A1	Serving becomes better than threshold
Event A2	Serving becomes worse than threshold
Event A3	Neighbour becomes offset better than serving
Event A4	Neighbour becomes better than threshold
Event A5	Serving becomes worse than threshold1 and neighbour becomes better than threshold2
Event A6	Neighbour become offset better than S Cell (This event is introduced in Release 10 for CA)
Event B1	Inter RAT neighbour becomes better than threshold
Event B2	Serving becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2
Event C1	CSI-RS resource becomes better than threshold
Event C2	CSI-RS resource becomes offset better than reference CSI-RS resource

Kemudian kita sering mendengar tentang System Information Block atau SIB ,

berikut kategori SIB yang ada pada sistem telekomunikasi mobile.

LTE system information blocks	Description
MIB	Carries physical layer information of LTE cell which in turn help receive further SIs, i.e. system bandwidth
SIB1	Contains information regarding whether or not UE is allowed to access the LTE cell. It also defines the scheduling of the other SIBs. carries cell ID, MCC, MNC, TAC, SIB mapping.
SIB2	Carries common channel as well as shared channel information. It also carries RRC, uplink power control, preamble power ramping, uplink Cyclic Prefix Length, sub-frame hopping, uplink EARFCN
SIB3	carries cell re-selection information as well as Intra frequency cell re-selection information
SIB4	carries Intra Frequency Neighbors(on same frequency); carries serving cell and neighbor cell frequencies required for cell reselection as well handover between same RAT base stations(GSM BTS1 to GSM BTS2) and different RAT base stations(GSM to WCDMA or GSM to LTE or between WCDMA to LTE etc.) . Covers E-UTRA and other RATs as mentioned
SIB5	Carries Inter Frequency Neighbors(on different frequency); carries E-UTRA LTE frequencies, other neighbor cell frequencies from other RATs. The purpose is cell reselection and handover.
SIB6	carries WCDMA neighbors information i.e. carries serving UTRA and neighbor cell frequencies useful for cell re-selection
SIB7	carries GSM neighbours information i.e. Carries GERAN frequencies as well as GERAN neighbor cell frequencies. It is used for cell re-selection as well as handover purpose.
SIB8	carries CDMA-2000 EVDO frequencies, CDMA-2000 neighbor cell frequencies.
SIB9	carries HNBID (Home eNodeB Identifier)
SIB10	carries ETWS prim. notification
SIB11	carries ETWS sec. notification

Sedangkan ini untuk 3Gnya :

System information block in UMTS type	Function(Information carried)
SIB1	NAS information,timer related information mainly used in IDLE/CONNECTED Mode
SIB2	available URAs(max. 8 URAs in a cell)
SIB3	cell selection/reselection parameters used by UE in IDLE mode, if SIB4 is not present then it can also be used by UEs(in CONNECTED MODE).
SIB4	cell selection/reselection parameters used by UE in CONNECTED mode,if not present SIB3 to be used by UE
SIB5	Carry info. on common physical channels(PICH/AICH/P-CCPCH/PRACH/SCCPCH) for UE(in IDLE mode), in the absence of SIB6 it is also used for UE in CONNECTED state.
SIB6	Carry info. on common physical channels(PICH/AICH/P-CCPCH/PRACH/SCCPCH) for UE(in CONNECTED mode), in the absence of SIB6, UE need to use SIB5
SIB7	carry fast changing cell parameter informations(uplink interference levels,dynamic persistence value)
SIB8	carry static information for CPCH (only for FDD use)
SIB9	carry dynamic information for CPCH (only for FDD use)
SIB10	DRAC procedure related information(sent over FACH channel)
SIB11	carry measurement control information(UE in IDLE mode), If SIB12 is absent it is also used for UE in CONNECTED mode.
SIB12	carry measurement control information(UE in CONNECTED mode), If SIB12 is absent, SIB11 can be used by UE
SIB13-SIB13.4	carry ANSI-41 parameter related informations used for ANSI-41 core networks.
