Abstract

In this paper, we propose an optimal Joint Call Admission Control (JCAC) in next generation wireless networks, where different radio access technologies (RAT) coexist in a co-located way. Moreover, we study the impact of the different RAT´s radius coverage area in the system performance and optimal policy structure. The Semi-Markov Decision Process (SMDP) framework is used for modeling of the JCAC proposed and the value iteration algorithm is used to compute the optimal policy. Numerical results show that variation in the proportionality of the radius of RAT coverage area impact on system performance.
