“…In [18], a new resource-dimensioning concept based on both the allowable noise-rise and traffic statistics is presented. The soft blocking probability based on outage probability and the assumption of the Poisson arrival and exponential services time are first derived, with a consistent view on traffic dimensioning.…”

One of the research challenges in cellular networks is the design of an efficient model that can reduce call blocking probability and improve the quality of service (QoS) provided to mobile users. Blocking occurs when a new call cannot be admitted into the network due to channel unavailability caused by limited capacity or when an ongoing call cannot be continued as it moves from one base station to another due to mobility of the user. The proposed model computes the steady state probability and resource occupancy distribution, traffic distribution, intra-cell and inter-cell interferences from mobile users. Previously proposed models are reviewed through which the present model is built for use in emerging wireless networks so as to obtain improved QoS performance. The developed model is validated through simulations in MATLAB and its equations implemented using Java Programming Language. The results obtained indicate reduced call blocking probability below threshold.

In this paper, we study blocking and outage probabilities in data CDMA networks. Interactions between traffic and interference stochastic characteristics are considered. Different from the traditional approaches where traffic activity factor was used to represent impact of stochastic traffic, we investigate traffic impact jointly with considering the interactions from interference process. Appropriate model is constructed to factor in both traffic and interference variations in the system. We built simulation environment to detect the impacts from correlations in traffic and frequency of variations in the interference. Our results show that, gain form interactions between stochastic traffic and interference processes, traffic correlation is beneficial when system is under same load. These parameters affect blocl{ing and outage probability significantly and have to be carefully considered in capacity estimations. Our study demonstrates that system performance was overestimated when there are no such considerations in performance analysis.
