RRC Connection Reestablishment The RRCConnectionReestablishment message is used to resolve contention and to re-establish SRB1.RRC Connection Reestablishment Reject The RRCConnectionReestablishmentReject message is used to indicate the rejection of an RRC connection reestablishment request.RRC Connection Reestablishment Request The RRCConnectionReestablishmentRequest message is used to request the reestablishment of an RRC connection.RRC Connection Reject The RRCConnectionReject message is used to reject the RRC connection establishment.RRC Connection Request The RRCConnectionRequest message is used to request the establishment of an RRC connection.RRC Connection Setup The RRCConnectionSetup message is used to establish SRB1.

SRB11

CounterCheckThe CounterCheck message is used by the E-UTRAN to indicate the current COUNT MSB values associated to each DRB and to request the UE to compare these to its COUNT MSB values and to report the comparison results to E-UTRANCounterCheckResponseThe CounterCheckResponse message is used by the UE to respond to a CounterCheck message.CSFBParametersRequestCDMA2000The CSFBParametersRequestCDMA2000 message is used by the UE to obtain the CDMA2000 1xRTT Parameters from the network. The UE needs these parameters to generate the CDMA2000 1xRTT Registration message used to register with the CDMA2000 1xRTT Network which is required to support CSFB to CDMA2000 1xRTT.CSFBParametersResponseCDMA2000The CSFBParametersResponseCDMA2000 message is used to provide the CDMA2000 1xRTT Parameters to the UE so the UE can register with the CDMA2000 1xRTT Network to support CSFB to CDMA2000 1xRTT.HandoverFromEUTRAPreparationRequest (CDMA2000)The HandoverFromEUTRAPreparationRequest message is used to trigger the handover preparation procedure with a CDMA2000 RAT. This message is also used to trigger a tunneled preparation procedure with a CDMA2000 1xRTT RAT to obtain traffic channel resources for the enhanced CS fallback to CDMA2000 1xRTT, which may also involve a concurrent preparation for handover to CDMA2000 HRPD.MeasurementReportThe MeasurementReport message is used for the indication of measurement results.MobilityFromEUTRACommandThe MobilityFromEUTRACommand message is used to command handover or a cell change from EUTRA to another RAT (3GPP or non-3GPP), or enhanced CS fallback to CDMA2000 1xRTT.ProximityIndicationThe ProximityIndication message is used to indicate that the UE is entering or leaving the proximity of one or more cells whose CSG IDs are in the UEs CSG whitelist.RRCConnectionReconfigurationThe RRCConnectionReconfiguration message is the command to modify an RRC connection. It may convey information for measurement configuration, mobility control, radio resource configuration (including RBs, MAC main configuration and physical channel configuration) including any associated dedicated NAS information and security configuration.RRCConnectionReconfigurationCompleteThe RRCConnectionReconfigurationComplete message is used to confirm the successful completion of an RRC connection reconfiguration

SRB12

RRCConnectionReestablishmentCompleteThe RRCConnectionReestablishmentComplete message is used to confirm the successful completion of an RRC connection reestablishment.RRCConnectionReleaseThe RRCConnectionRelease message is used to command the release of an RRC connection.RRCConnectionSetupCompleteThe RRCConnectionSetupComplete message is used to confirm the successful completion of an RRC connection establishment.SecurityModeCommandThe SecurityModeCommand message is used to command the activation of AS security.SecurityModeCompleteThe SecurityModeComplete message is used to confirm the successful completion of a security mode command.SecurityModeFailureThe SecurityModeFailure message is used to indicate an unsuccessful completion of a security mode command.UECapabilityEnquiryThe UECapabilityEnquiry message is used to request the transfer of UE radio access capabilities for EUTRA as well as for other RATs.UECapabilityInformationThe UECapabilityInformation message is used to transfer of UE radio access capabilities requested by the EUTRANUEInformationRequestThe UEInformationRequest is the command used by E-UTRAN to retrieve information from the UE.UEInformationResponseThe UEInformationResponse message is used by the UE to transfer the information requested by the E-UTRAN.ULHandoverPreparationTransfer (CDMA2000)The ULHandoverPreparationTransfer message is used for the uplink transfer of handover related CDMA2000 information when requested by the higher layers.DLInformationTransferThe DLInformationTransfer message is used for the downlink transfer of dedicated NAS information.ULInformationTransferThe ULInformationTransfer message is used for the uplink transfer of dedicated NAS information.

SRB2

DLInformationTransferThe DLInformationTransfer message is used for the downlink transfer of dedicated NAS information.ULInformationTransferThe ULInformationTransfer message is used for the uplink transfer of dedicated NAS information.
