Improving architecture of LTE mobile network for IoT services provisioning

In this paper we analyze the current state of 3G mobile networks in Ukraine and study the prospects and ways of introducing IoT services based on 4G/5G technologies. We improve architecture of LTE mobile network to provide IoT services through the allocation of narrowband spectrum and the transfer of functions from the eNodeB base station to IoT controller. We propose narrowband spectrum allocation method for IoT in LTE spectrum to reduce inter-cell interference impact on the signal-to-noise ratio at the edges of cells. We also propose method of traffic prioritization to ensure IoT E2E QoS in a heterogeneous LTE/IoT network.
