This paper addresses the analysis of LTE performance in order to assess the quality of data services provided by the network. Models were developed in order to characterise and analyse a sample of experimental measurements from a large service area of an operator's network. These models and algorithms establish a statistical classification for the cells, enabling a proper analysis of the quality of...
Long Term Evolution (LTE) subscribers expect seamless Quality of Experience (QoE) during their ubiquitous Internet access. Due to the high degree of application and content diversity, the amount of system resources that enable good QoE is application session specific and varies on a wide scale. Accordingly, good QoE requires dynamic and adaptive application session level resource management. The standard...
There is a growing demand for mobile networks to support high Quality of Service (QoS) for multiple applications in critical single all IP-based infrastructures. In addition, satisfying end-users' Quality of Experience (QoE) is still crucial. For these reasons, the Third-Generation Partnership Project (3GPP) has deployed a QoS framework for Long Term Evolution (LTE) based networks. However, the users'...
The constant evolution and growth of multimedia applications supported by today's mobile devices leads to an increase on the demand for video based services which impose new requirements in terms of bitrate and delay. In order to face these challenges, LTE appears as a technology capable of dealing with the video traffic load on mobile networks. However, given the inherent nature of mobile networks...
