Quality-of-experience (QoE) produces the blue print of human perception, feelings, needs and intentions, while Quality-of-Service (QoS) is a technology centric metric used to assess the performance of a multimedia services and/or network. .It is quite important for service/content providers to understand user/customer experience requirements in order to improve the service quality or the content recommendation. With advent of 3G and 4G wireless networks, and efficient smart phones, the

Thus,it is also important for telecom operators to understand the impact of wireless network performances on the user experience in mobile environment. On the fly evaluation of user experience for multimedia services is a challenging problem especially in mobile environments. It implies the collection and the correlation of a mixture of variables on network conditions, on the service, as well as on the user itself. This paper proposes an innovative mobile application that can be used for measuring user quality-of-experience on the fly with a high accuracy and the consideration of multiple parameters about the user, the network and the system. This application takes advantages of current advances in mobile technologies to measure user experience directly on the user device. In addition, it aims to preserve the user privacy by transmitting only estimated quality-of-experience to the service provider. From the telecom perspective [2], the network's performance can be monitored by collecting and investigating key performance indicators such as QoS parameters. These technical indicators are measured at the different levels in a wireless network. The examples of theseindicators collected at network layer are bandwidth, delay, jitter, packet loss rate, etc., and at end-user device level(e.g. noise/interference level, signal strength, connection establishment time, drop rate, etc.). On the other hand, from the user perspective [2], the network's performance can be monitored by collecting user feedback, i.e. QoE data. In contrast to QoS, QoE provides an assessment of human perceptions, feelings, emotions and intentions with respect to a particular product, service or application [18] . QoE is affected by various technological, business and contextual factors [19] [3].
