Abstract Increasing cellular trac is the driving force for innovations in wireless communications. While voice trac is not expected to increase much and does not require 4G systems, trac for video and data applications is expected to grow with a rate of 100% per year. Smart mobile devices, tablets and laptop dongles will certainly make this a reality. On the other hand the supply side cannot grow with the same rate. Base stations, eNB, pico- and femtocells will bring more heterogeneity in space and new applications will bring more heterogeneity in demand over time. Designing for over-provisioning capacity has been the standard approach to stabilize trac, but is will be harder and harder, with more congestion situations in time (busy hour) and space (crowded cell) which will break application trac and give bad quality-of-experience of users. Furthermore, overprovisioning comes with more power consumption and higher financial expenditures for infrastructure and operating costs. The user-in-the-loop (UIL) approach o ers a solution orthogonal to the traditional supply-only view. In addition to technical improvements, having a temporal demand control can alleviate the severity of busy-hour situations which formerly caused congestion and connection failures. Demand shaping is implemented by a dynamic usage-based tari and adaptive rates depending on the load condition. The users in a cell are part of a closed control loop which reacts in cases of severe demand overload. In this paper three di erent service classes are controlled individually and results from analysis and simulation show the performance in stationary and dynamic scenarios. The economics of tari s and dynamic prices and the resulting operator revenue on one side is compared to the dissatisfaction of rejected users and this gives decision indicators for the investment into new infrastructure. Overall this saves money, energy and turns situations of hard congestion into an elastic stationarity which is in the interest of both users and operators.
