QoE Optimization in a Live Cellular Network through RLC Parameter Tuning

Abstract: The mobile communication networks sector has experienced a great evolution during the last few years. The emergence of new services as well as the growth in the number of subscribers have motivated the search for new ways to optimize mobile networks. In this way, the objective pursued by optimization techniques has been evolving, shifting from the traditional optimization of radio parameters to the improvement of the quality perceived by users, known as quality of experience (QoE). In mobile networks, the radi… Show more

“…Among them, α k is determined by a certain linear search. Existing search algorithms include exact linear search and approximate linear search methods such as: Wolfe linear search, Armijo linear search and Goldstein linear search and so on [28]. The authors in [29] proved the global convergence of the (Polak-Ribière-Polyak) PRP algorithm [30] in the conjugate gradient method when Armijo linear search is used [31,32].…”

“…In the literature, some models are based on subjective Mean Opinion Score (MOS) to derive the QoE; however, all of them depend on endto-end throughput perceived by the users [110]. On the other hand, following a similar methodology taken in [111], we take a more generalized approach, i.e., instead of using a specific MOS model for file transfer service, time to download has been used as an indicator of the QoE perceived by the users.…”
