Abstract [en]

Current wireless networks have no knowledge on the type and characteristics of the specific mobile services and contents they are providing (they are agnostic). On the other hand, associated to richer content and more advanced devices, improvement of Quality of Experience (QoE) levels perceived by each user looks as one of the main goals of the different actors in the telecommunication's ecosystem. In this respect, network awareness of the transferred content types and their quality requirements can be important to deliver them fulfilling user requirements while optimizing the utilization of network resources. In this paper, we explore the effect of including semantic knowledge in the radio resource management (RRM) schemes of cellular systems as a way to reach this balance for video streaming service. To make this possible, we propose a number of semantic-aware RRM schemes using information about the video playback's current status, and investigate their performances based on the reduction of the total time of interruptions (TTI) perceived by users when a video streaming content is played. The achieved results are compared to those of the standard agnostic scheme implemented in the cellular networks. The outcomes show that incorporating semantic-aware RRM schemes, more users can receive the content provided by a network within a tolerable level of TTI, while the number of users receiving High Definition (HD) videos can be increased, which in general terms might reduce the investment in infrastructure to fulfill users' requirements.

Abstract [en]

With the development of mobile networks, customer needs and behaviourshave changed. Mobile communications means so much more than simplevoice communication; there is now mobile Internet with web surfing, videophone,streaming media, and micro blogging. The objective of network optimizationhas gradually shifted from enhancing network performance to improvequality of experience (QoE). Therefore, assessing and optimizing QoEis the trend for optimizing future mobile networks.

Today, users want reliable access for their content, wherever they go inthe network. To deliver the best possible experience to mobile broadbandsubscribers, operators need new ways to assess performance that will enablethem to build and manage their networks in the most efficient way. The newparadigmatic eco system (user-interface-network-content) requires novel anddisruptive end-to-end considerations in order to enable and sustain the nextgeneration of services and user experience. Thus, the extraordinary adoptionof mobile connectivity by end users, and the need for optimized bandwidthmanagement network resource, on the one hand, and the growing interest forgood quality content delivery/consumption, is boosting the creation of newnetwork solutions.

We consider that by taking advantage of the capacity to support multimedia platforms and applications of mobile devices (e.g. smartphones, tablets,etc.) is possible to incorporate and provide awareness to the wireless infrastructuresin the context of cross-layer systems to manage the resource allocationaccording to expected QoE levels. In this thesis, we address the questionon how to implement QoE-aware mobile networks and evaluate differentschedulers oriented to take advantage of the proposed architecture. We showthat by providing QoE-awareness to the network infrastructure is possible toimprove user’s QoE and generate impacts in the utilization of the networkresources. With this study, we provide insights into the broader question ofwhether future mobile infrastructures can be deployed considering QoE besidesthe classical QoS considerations.
