Abstract
Direct-to-satellite narrowband Internet of Things (NB-IoT) is a prominent use case in non-terrestrial network (NTN) communications, rapidly approaching commercialization. The scalability of these systems relies heavily on the access procedures implemented by user equipments. While standardized access protocols perform well in terrestrial networks, their efficiency in NTN environments supporting massive machine-type communications remains uncertain. In this work, we analyze the latest access procedure features introduced in the 3GPP standard for IoT-NTN, specifically contention-based early data transmission (CB-EDT) in Release-19. We compare the solution with legacy procedures to assess its potential for future deployments. The results highlight substantial advantages when implementing CB-EDT in terms of energy savings, access completion time, and spectral efficiency, making it an optimal candidate for future massive IoT satellite deployments.
The first comprehensive and in depth measurement for NB-IoT NTN over GEO reveals that as an energy-saving mechanism, Power Saving Mode fundamentally reshapes NB-IoT NTN traffic into a bursty and access-driven communication pattern and thus has a considerable influence on the end-to-end delay and energy consumption.

This work finds that the bottleneck lies in the direct-to-satellite upload stage, where usable contacts are scarce and underutilized, and proposes Co-DtS, a multi-interface upload system that promotes observed beacons into cross-interface coordination signals.

This work presents the first large-scale, in-the-wild measurement of DtS using one of the world's largest operational satellite IoT networks, and redesigns the DtS protocol with three drop-in enhancements: a NACK-driven reliability strategy that unlocks higher throughput, a flow-control mechanism that trims long-tail d...
