Based on the assumption specific IoT and M2M devices used in FoF require a stable communication environment (described by certain requirements such as bandwidth, latency, security policy, etc.), the use case contributes to the efficiency of FoF operations through research and development on a Network App which provides industrial 5G connectivity for those IoT and M2M devices, assuring them required QoS with the help of integrated SLA/SLS monitoring capabilities as part of the Network App. The Network App is an integral part of the 5G IoT System, a product that provides 5G connectivity for IoT/M2M devices connected to it via various physical interfaces (e.g., serial, USB, Ethernet). Since 5G has the potential to offer network performances required by the factory process, the solution utilises 5G network functions available to monitor assured QoS for the communication links.
