The RRC protocol is the signaling exchanged between the mobile and the evolved Node Base station (eNB) over the LTE-Uu radio interface . The RRC protocol performs the following functions: – Broadcast of system information related to the characteristics of the radio interface.
Read moreWhat are the functions of RRC?
The major functions of the RRC protocol include connection establishment and release functions , broadcast of system information, radio bearer establishment, reconfiguration and release, RRC connection mobility procedures, paging notification and release and outer loop power control.
Read moreWhat is RRC and NAS messages?
The RRC is the highest layer in the control plane of the Access Stratum (AS). The RRC also transfers messages of the Non-Access Stratum (NAS), which is located above the RRC layer. NAS messages are used to control communications between a UE and the Evolved Packet Core (EPC).

RRC CONNECTION RECONFIGURATION message is the command to modify an RRC connection . The purpose of this procedure is, · To establish/modify/release Radio Bearers. · To perform Handover. · To setup/modify/release Measurements.
Read moreWhat is RRC inactive in 5G?
In 5G, they have introduced new RRC Stats called “RRC Inactive” to minimize latency as well as to reduce signalling load . Transitions from RRC Inactive to Connected is very quick as UE Context is stored at gNB and UE. NG signalling keep alive between gNB to AMF, GTP-U also remain alive between gNB to UPF.

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.
