Keywords: QoE, QoS, mobile networks, user experience
AbstractThe growing demand for a fast and cheap Internet access, especially via mobile devices, significantly changes the perception for the Internet services provided by the mobile operators. Easy access to the Internet “world” through the mobile technologies like LTE-Advanced provides full support of different types of services and applica- tions which have strict requirements regarding network performance, bandwidth and speeds. This is a big challenge for the mobile operators in order to provide adequate support for all the users and various types of services. On the other hand, the users expect certain quality levels to be maintained. This paper describes and gives examples of the main QoE indicators measured from live mobile networks, how to optimize them and how to come close or achieve the apex of the current mobile networks performance.
