This new procedure in 5G NR SA helps to reduce the amount of signaling that occurs during UE state transitions from Idle to connected state and therefore makes it possible to notably lower both latency and battery consumption of devices which we understand as evaluative requirements for many Internet of Things(IoT) and 5G use cases.
In this paper we will get an understanding on RRC Resume procedure in 5G NR SA and its key aspect by going through an example case study of two NR Cells scenario and signaling of messages exchanged as a result of this new procedure and key points to explore as a solution when UE moves to different 5G NodeB
