itial BWP of the cell. cellBarred: this 1-bit parameter indicates whether the mobile can camp on the cell or not. intraFreqReselection: if the cell is prohibited, this 1-bit parameter indicates whether the mobile can search for another cell on the same carrier band. 9.1.2. SIB1 message The SIB1 message provides the information that allows the mobile to know whether it is authorized to access the cell and, if applicable, the information necessary to retrieve the other SIB messages. The SIB1 message contains the following parameters: SystemInformationBlockType1 cellselectionInfo cellAccessRelatedInfo ConnEstFailureControl SI-schedulingInfo servingCellConfigCommon ims-EmergencySupport ecallOver-IMS-Support ue-TimerAndConstants uac-BarringInfo cellSelectionInfo: this parameter provides the minimum value expected to select the cell. The mobile selects the cell if the power measured from the Reference Signal Received Power (RSRP) is greater than the threshold. 5G-NR Radio Interface - Radio Access Procedure cellAccessRelatedInfo: this parameter provides various pieces of information concerning access to the cell, such as the identities of the networks, MCC (Mobile Country Code) and MNC (Mobile Network Code), which share the cell, the number of the TACs (Tracking Area Codes) and cell identity. ConnEstFailureControl: in the event of no response from the gNB during a radio connection request, the mobile increments a connection establishment failure counter. When this counter reaches a threshold, the power measured on the RSRP reference signal of the cell on which the mobile is camping is degraded. This parameter provides information on the number of failures before applying a penalty of the measure, and provides the value of the penalty as well as the duration. SI-schedulingInfo: this parameter provides the information that defines the grouping in SI (System Information) messages SIB2 to SIB9 and the periodicity of each group. servingCellConfigCommon: this parameter provides the configuration of the radio access on the upl
