“…Wireless data applications produce data that may have different characteristics from those of wired data applications and wireless voice data [18]. This article describes the simulation results of data service in mobile (cellular) telecommnunication networks, using the simulator named 'Simula2' [29,30,31], which take into account the self-similarity [5,21,26] of the network traffic. We use the distributions heavy tailed Weibull and Pareto [17] to simulate the data traffic and the resource occupation time for data service, respectively.…”

“…The smoothing is performed only to make the graph easier to read 8. The channel utilization for slotted/non-slotted messages is calculated as the number of bits in slotted/non-slotted messages during a certain time period, e.g., a slot, divided by the product of the length of the time period (e.g., 80 ms) and the channel capacity (9600 bps).…”

IP and cellular phone networks used to be isolated from each other. In recent years however, the two networks have started to overlap with the emergence of devices that access the Internet using cellular infrastructures. One important question then, given this overlap, is whether actions or threats on the Internet side can impact the telecom or cellular side. We address this problem in the paper and specifically consider threats on the paging channel, which is a key conduit shared by both Internet and cellular traffic.Our contributions are as follows: we illustrate through experiments on a CDMA2000 cellular network that overloads or attacks launched from the Internet can significantly increase the paging load and increase the delay of paging messages, including cellular call setup requests, which in turn could lead to non-completed calls; we derive a simple but accurate queuing model for the paging system in a CDMA2000 network and use this model to demonstrate that the paging channel exhibits sharp rather than graceful degradation under load; and through this model, we identify critical parameters that impact paging performance. Although our study is focused on CDMA2000 networks, we believe that similar problems exist in other types of cellular networks that employ a single control channel with limited bandwidth for both voice and data services.
