Title Calculating a single figure of merit (SFOM) in LTE: a predictor of quality of experience (QoE)

Abstract An exigent assignment for network planners of modern mobile systems technologies like Long Term Evolution (LTE) is to predict the subscriber’s satisfaction during the delivery of services over the wireless network and their satisfaction level during journeys such as freeway and train journeys. There is great need for a procedure and for a simulation software tool based on a methodology that would assist the mobile network planners in overcoming this arduous task.

This thesis proposes and implements a new and novel solution to the aforementioned problem by proposing a method of calculating a Single Figure of Merit (SFOM), which assesses the user’s Quality of Experience (QoE) based on the technical measure of the Quality of Service (QoS) reported by the network. The proposed SFOM reduces the number of metrics involved in calculation in comparison to the earlier QoE computation approaches. The resulting SFOM proves to be a good indicator of the user’s QoE with the network for the complete duration of a journey along pre-defined and random paths. The SFOM calculation method has been implemented as an addition to an open-source Matlab-based LTE System Level Simulator.

This thesis also proposes and implements two novel special event walking models, named as: “Starburst Walking Model” (e.g. people gathering or leaving a sports arena) and the “Trainload Walking Model” (e.g. trainload of people moving from one point to another) which are a novel addition to the mobility management aspects of the simulator.

Network planners can benefit from this improved simulation tool to evaluate different arrangements and position mobile assets, with a view to optimizing the user’s experience and minimizing capital costs. The work supplementing the open-source Matlab-based LTE System Level Simulator’s functionality was published at the following IEEE conference:

Making use of the improved functional ability of the simulator, a new and novel methodology which facilitates comparing alternative network topologies and assigns SFOM to random or predefined paths in a LTE environment was published at the following IEEE Conference:
