The objective of this research is to propose an architectural alternative to 4G/5G on the basis of apprehending the various pain points related to the state of the art and to solve them by eventually realising a new mobile network framework, a new multiple access methodology and a smart mobility management model.
The factors that will drive the ontogenesis of next generation mobile networks are namely the evolution of the mobile devices and ever incremental demand for data traffic triggered by the proliferation of smart phones and the dongles. Apprehending an exponential growth in numbers of the mobile users, the cell size of the mobile network will shrink. Eventually, there will be an upsurge of signaling messages interchanged between the device and the network due to an increase in handover related operations. Attempt should be made to reduce the interaction with the network and simplify the mobility and location management related processes. In this thesis we set out a technical architecture of a mobile network to abridge the intricate mobility and location management processes as well as the addressing principle to render more operational efficiency and cater to the needs of the data hungry applications that we envisage for the next generation devices and networks. Our primary objective is to propose a technique of wireless communication where we render intelligence to the physical layer to take part in some processes which is otherwise confined to higher layer signalling activities, say, for example, addressing of a node. If we have a method to actuate user identification for the purpose of mobility management by implementing lower layer processes, we can simplify or eliminate the layer 7 processes and hence reduce the intricacy and costs of mobile network elements and user equipment. The thesis delves in the practicalities of development and implementation of such a technology for closed user group communication, global mobile networks and device to device communication. The thesis further discusses the importance of incorporating error correction procedures to ensure robustness of the double ring constellation scheme proposed as a proof of concept. Wireless communication based on colour signals is another form of ‘physical layer network addressing’ which has been proposed in subsequent chapters. The implementation scenarios set out in this thesis are Wireless Local Loop (WLL) communications and high definition voice transcoding.
