Downlink LTE RRC message used to modify radio configuration, measurements, mobility behavior, bearer settings, and connected-mode control after setup.
LTE RRC Messages
LTE RRC messages are the control-plane message set between the UE and the eNodeB. This page groups the LTE RRC message space into broadcast, setup, reconfiguration, mobility, paging, security, and capability paths so the right message branch is easy to open from a trace or procedure.
Start with system information for access and idle context, move into LTE RRC for dedicated control, then use initial access, handover, or paging when the message sequence needs procedure context.
Protocol family: LTE RRC Main spec: 3GPP TS 36.331 Architecture: 3GPP TS 36.300 Idle mode: 3GPP TS 36.304 Release: Release 18

Open the branch that matches the part of the trace or procedure you are reading.
Broadcast and system information MIB, SIB1, and the wider SIB set used for access, camping, paging, and idle behavior. Connection setup and release RRC connection request, setup, setup complete, reject, release, and return-to-idle paths. Measurements and mobility Measurement configuration, MeasurementReport, reconfiguration, and mobility control paths. Paging and return to service Paging behavior, idle-to-connected return, and broadcast context needed to read that path. Security and capability exchange Security Mode, capability transfer, and connected-mode control that changes later behavior. Decoder and trace reading Decode LTE RRC payloads first, then map the message into the right procedure or message family.
