Traffic Measurement and Analysis in Cellular Data Charging System

In recent years, the development of 3G/4G networks makes people pay more attention to the traffic accounting in data-based charging cellular networks. Although this charging system has been worked many years and updated frequently, we find that there are still some points which can be improved. First, we measure the traffic in poor signal between end devices and base station by different operators, discovering some billing loopholes and overcharge. Our experiment shows the overcharge can be 28.4% of the data we want. In addition, we analyse the traffic on phones in one extreme case, and detect that the retransmission only take place no more than 10% of the whole traffic. While the reconnection volume can be three times of the goodput. At the end, we propose feasible solutions and discuss possible future directions.
