A highly reliable power saving method for IoT devices in a wireless environment

During recent 3GPP standards meetings, diverse approaches were put forward to mitigate power consumption during state transitions (Connected/Idle) in IoT devices. Notably, the UE assistance information and Data-Inactivity methods were introduced to enhance power efficiency through the RRC Release procedure. However, these methods were found to be constrained by specific scenarios. This paper addresses the limitations of the UE assistance information and Data-Inactivity method while presenting a novel approach that boosts battery efficiency compared to existing methods and addresses issues encountered in exceptional situations. Furthermore, as a future study, we propose exploring a method to bolster security and enhance the stability of the procedure outlined in this paper.
