Improving Call Admission Control in 5G for Smart Cities applications

In this paper, we discuss the Call admission control (CAC) issue in 5G network and the state of the art in this field. Which study will be conducted to suggest and develop an algorithm of admission control modeling in the case of New Radio access namely NR 5G. It will also tackle the issue of handover and more generally mobility management, power control and interference. All this will be done taking into consideration and ensuring acceptable QoS and QoE as well as an energy saving and power efficiency. We focus, in our study, on the development of an algorithm for the improvement of call admission control based essentially on a minimal consumption of energy. In the algorithm we consider one base station (RRH) in ultra dense network environment by considering Heterogeneous network and CRAN systems (H-CRAN).
