full_form: System Information Block
context: System information block type 5 (SIB 5) and System information block type 5bis (SIB 5bis)define common channels to be employed in Idle mode [4]. In a cell, a single or several PCHs may be established. Each Secondary Common Control Physical Channel (SCCPCH) indicated to the UE in system information may carry up to one PCH. Thus, for each defined PCH there is one uniquely associated PICH also indicated. In case that more than a single PCH and associated PICH are defined in SIB 5 or SIB 5bis, the UE shall perform a selection according to the following rule: - The UE shall select a SCCPCH from the ones listed in SIB 5 or SIB 5bis based on IMSI as follows: "Index of selected SCCPCH" = IMSI mod K, where K is equal to the number of listed SCCPCHs which carry a PCH (i.e. SCCPCHs carrying FACH only shall not be counted). These SCCPCHs shall be indexed in the order of their occurrence in SIB 5 or SIB 5bis from 0 to K-1. For GSM-MAP, i.e. "IMSI (GSM-MAP)" is given as sequence of digits of type
description: System Information Block (SIB) is a message that contains essential information about the cell and network configuration, which is broadcast by the base station to user equipment (UE). SIB5 and SIB5bis specifically define common channels employed in Idle mode, including Paging Channel (PCH) and Secondary Common Control Physical Channel (SCCPCH), and provide rules for UE selection of SCCPCH based on IMSI.
explanation: The context describes the content and purpose of System Information Block type 5 (SIB 5) and SIB 5bis, which are messages broadcast by the base station to UEs. The information contained in these blocks is used by UEs to select common channels for communication in Idle mode. Therefore, based on this context, SIB is classified as a Message.
