Large-scale deployments of massive machine type communications involve several challenges on cellular networks. To address the challenges of massive machine-type communications, or more generally, the Internet of Things (IoT), the 3GPP has developed Narrowband IoT (NB-IoT) as part of Release 13. NB-IoT is designed to provide better indoor coverage, support of a massive number of low-throughput devices, with relaxed delay requirements, and lower energy consumption. NB-IoT reuses Long Term Evolution functionality with simplifications and optimizations. Particularly for small data transmissions, NB-IoT specifies two procedures to reduce the required signaling: one of them based on the control plane and the other on the user plane (UP). In this work, we provide an overview of these procedures as well as an evaluation of their performance. The results of the energy consumption show both optimizations achieve a battery lifetime extension of more than two years for a large range in the considered cases, and up to eight years for CP with good coverage. In terms of cell capacity relative to Service Request, CP achieves gains from 26 to 224 percent, and UP ranges from 36 to 165 percent. The comparison of CP and UP optimizations yields similar results, except for some specific configurations.

大规模机器类型通信的窄带IoT数据传输过程

大规模机器类型通信的大规模部署在蜂窝网络上涉及多个挑战。为了应对大规模机器类型通信(或更笼统地说,物联网(IoT))的挑战,3GPP开发了窄带物联网(NB-IoT)作为版本13的一部分。NB-IoT旨在提供更好的室内覆盖范围支持大量的低吞吐量设备,并具有轻松的延迟要求和更低的能耗。NB-IoT通过简化和优化重用了长期演进功能。尤其对于小型数据传输,NB-IoT指定了两个过程来减少所需的信令:一个过程基于控制平面,另一个过程基于用户平面(UP)。在这项工作中,我们提供了这些程序的概述以及它们的性能评估。能耗的结果表明,在考虑的情况下,两种优化都可以在较大范围内将电池寿命延长两年以上,而对于具有良好覆盖范围的CP,则可以延长电池寿命长达八年。就相对于服务请求的小区容量而言,CP的增益为26%至224%,UP的范围为36%至165%。CP和UP优化的比较产生了相似的结果,除了一些特定的配置。
