LTE RRC connection setup. Establishing an RRC connection in LTE typically involves the following steps: UE initiates a session to the eNodeB using a random RA-RNTI. eNodeB assigns a C-RNTI and sends timing adjustment to the UE. UE adjusts the timing and sends an RRC Connection Request via the UL-SCH channel.

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.
