The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station . This protocol is specified by 3GPP in TS 25.331 for UMTS, in TS 36.331 for LTE and in TS 38.331 for 5G New Radio.
Read moreWhat is RRC message?
The RRC messages are encrypted and checked for integrity . The RRC ConnectionReconfiguration message is used by the eNB entity to command a modification of the RRC connection. This message may relate to the configuration of the measurements, control of the mobility and configuration of the DRB default bearer.
Read moreWhat is RRC reestablishment?
The purpose of RRC CONNECTION RE-ESTABLISHMENT procedure is to re-establish the RRC connection, which involves the resumption of SRB1 operation and the re-activation of security (without changing algorithms).
Read moreWhat is RRC connection setup?
The RRC CONNECTION SETUP message is used to establish SRB1 . It contains configuration information for SRB1. This allows subsequent signaling to use the DCCH logical channel. The configuration for SRB1 can be a specific configuration or the default configuration.

The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station.
Read moreWhat is RRC connected state in LTE?
RRC Connected State LTE UE monitors control channels associated with shared data channel to determine if the data is scheduled for it or not . The Channel quality feedback information is also provided by the UE after measurements. It also performs neighbor cell measurements of UTRAN,EUTRAN and GSM cells.
