context: 4> if the first NPN identity included in the NPN-IdentityInfoList, the systemInformationAreaID and the valueTag that are included in the si-SchedulingInfo for the SIB received from the serving cell are identical to the NPN identity, the systemInformationAreaID and the valueTag associated with the stored version of that SIB: 5> consider the stored SIB as valid for the cell; 3> else if the first PLMN-Identity included in the PLMN-IdentityInfoList, the systemInformationAreaID and the valueTag that are included in the si-SchedulingInfo for the SIB received from the serving cell are identical to the PLMN-Identity, the systemInformationAreaID and the valueTag associated with the stored version of that SIB: 4> consider the stored SIB as valid for the cell; 2> if the areaScope is not present for the stored version of the SIB and the areaScope value is not included in the si-SchedulingInfo for that SIB from the serving cell: 3> if the UE is NPN capable and the cell is an NPN-only cell: 4> if
description: A System Information Block (SIB) is a type of message in LTE and 5G networks that contains essential system information, such as cell identity, tracking area code, and other parameters necessary for user equipment to access the network. SIBs are broadcast by base stations and received by user equipment.
explanation: The context describes how SIBs carry system information crucial for network access, implying they function as a form of communication between network elements. This aligns with the definition of a message.
