Abstract

Growth in volumes and types of data that have to be supported in future Internet of Things (IoT) applications is one of the key features in mobile networks transition from 4G+ to 5G. In this regard, IoT service providers have to ensure the massive multimedia data transfers in conjunction with machine-type messages. The need for simultaneous support of several categories of traffic implies the heterogeneity of 5G networks. To cope with this problem, 3GPP proposed and standardized the in-band deployment of Narrow-Band IoT (NB- IoT) technology. The paper presents a set of feasible strategies for sharing resources between multimedia data and data from sensors in a hybrid LTE/NBIoT wireless network. Based on the developed analytical framework, the paper provides a comparison of the proposed strategies, while giving recommendations on the choice of the optimal one.
