Application Service Monitoring in Cellular IoT Network

With 5G a reality, communication is not only getting faster and better, but also the new verticals, which were so far not serviced by the cellular industry, are supported. One of the areas where 5 G has promising impact is enabling the Internet of Things (IoT) communication. With higher spectrum and bandwidth, 5G enables massive number of devices to connect to the IoT networks. At the same time, the exponential growth of the number of connected devices puts unprecedented load on cellular infrastructure. Further, 5G enables IoT applications to control more devices remotely where low latency and high throughput are critical performance criteria - like healthcare and factory applications. For such applications, it is essential that the application service remains available and be responsive always. Continuous monitoring at all the layers is critical in ensuring the seamless and uninterrupted service availability, thus improving the user experience and efficient use of resources. In this paper, the authors explain the benefits of Application Service Monitoring (ASM) in coordination with the underlying transport in providing the best quality of experience for the user through a framework using 3GPP Service Enabler Architecture Layer (SEAL). The paper also provides a mathematical model of the Quality of Service (QoS) adaptation through Network and Vertical Application Layer (VAL) coordination feature of framework and substantiate the same with the simulation and its results. The paper finally provides simulation results explaining the benefits of using ASM framework with SEAL.
