4G wireless standard, Long Term Evolution (LTE), promises to guarantee delivering of band-consuming applications. In this context data-based services as web browsing with equipped video and video streaming are the most requested services by end user. In order to be able to use all LTE innovative features, Mobile Network Operators (MNO) need to also guarantee both an opportune Quality of Service (QoS)...
We consider Quality of Experience (QoE), measured in terms of Mean Opinion Score Listening Quality Subjective (MOS_LQS) for a Voice over LTE (VoLTE) application in realistic situations. Groups of service scenarios have been identified and the network performance simulated. We organized a listening panel to measure MOS according to standard procedures. MOS-LQS results and QoS metrics have been correlated...
In only a few ten years payment systems have undergone an incredible evolution passing from a physical transfer of cash to transactions exchanging money as digital data. Mobile Payment (m-payment) refers to one type of electronic payment, performed through mobile devices, such as mobile phones, smartphones, and tablets. To ensure trust and avoid frauds severe security requirements must be imposed...
Long Term Evolution (LTE) is the first fully IPbased 3GPP standard for wireless transmission system. Due to innovative features it is able to offer very high throughput (e.g. 100 Mbps in downlink) to end user. For this reason Mobile Network Operators (MNO) need to adopt efficient end-to-end QoS approach in order to improve service quality perceived by end user. This should be adopted especially in...
Long Term Evolution (LTE) is a 3GPP standard for wireless transmission systems. It is also the first 3GPP wireless standard full IP-based. Due to its possibility to reach very high throughput (e.g. 100 Mbps in downlink), an efficient end-to end QoS treatment is needed in order to guarantee a good QoS perceived by end user (QoE). Voice service delivered by LTE systems is Voice over IP (VoIP) service,...
The study of the end-to-end QoS (Quality of Service) features of wireless networks may give to mobile operators ways to manage the network infrastructures from a trustworthy and robustness perspective, to optimize the network usage and guarantee desired quality of services to end user. In this paper a review of studies on end-to-end QoS in LTE networks is presented. The most important features of...
