Defence of dissertation in the field of Communications Engineering, M.Sc. (Tech.) Sofonias Hailu

The dissertation focuses on the area of communications engineering, in particular on the 5th Generation of cellular mobile communications (5G). Unlike the previous generations, the design of 5G is driven by a large number of diverse use cases, which brought a new set of problems such as ultra-low latency, ultra-high reliability and extremely long battery life requirements, in addition to the traditional but exponentially growing throughput requirement. As such, the control plane design plays a key role in 5G to efficiently integrate and use all concepts that address diverse use cases and even directly addressing the requirements of some of the use cases.

Considering the large number of 5G use cases, the dissertation considers configurable and future proof control plane functions for mobility and spectrum sharing. These control plane functions do not only address diverse 5G use cases, but also ensure quick entry-to-market of future use cases. The performance of the control plane functions is also shown to outperform the previous cellular network generations, e.g. Long-Term Evolution (LTE), using simulation results.
