In this paper, a new system level approach for the wireless channel unreliability modeling is proposed. Firstly, in order to characterize the call interruption process due to the wireless channel unreliability, the Gilbert-Elliot model is used to obtain the probability distribution of the interruption time. Then, it is shown that link unreliability can be adequately modeled by considering a Poissonian call interruption process. This allows simplifying system level mathematical analysis and easily identifying the factors that mainly influence the performance of mobile cellular networks. For the characterization of the interruption process in real cellular networks, it is enough to know some few system level statistics that can be easily obtained at base stations. Then, with the proposed call interruption modeling, an elegant teletraffic analysis for the performance evaluation of mobile cellular networks considering both wireless link unreliability and resource insufficiency is developed.
