SDN Network Slicing for URLLC NB-IOT

Current mobile networks are considering mobile devices i.e. User Equipment (UE) associated to a single user. 3GPP has integrated Machine to machine communications and Narrow-Band IoT requirements only in recent releases. The Internet of Things (IoT) devices are autonomous, large in number and often lacking user interface. Different proprietary management solutions have been proposed and implemented to collect data and manage the IoT devices. This paper presents the results of analyzing 3GPP standards for managing device subscriptions such as the User Data Convergence (UDC). The UDC combined with the usage of SDN delivers network slicing to deliver Ultra Reliable Low Latency (URLLC) for Nb-IoT traffic required for industrial communications. A prototype of the design was developed and tested to check the feasibility and this paper presents the results that show the solution could work under the right setup.
