Measuring QoS Metrics in Femto/Macro Cellular Networks with CAC Policy

---

Due to the growing importance of deploying femtocell technology in the current mobile network operators, data traffic processing and handover (HO) management in such networks are challenging issues. Consequently, due to the mobility of femto users between indoor and outdoor environments, the HO traffic interplay between macrocell and femtocells should be addressed, by determining accurate HO rate and actual channel holding time. Classical methods for data traffic process and HO management cannot directly apply in such network. In this paper, we propose an adaptive call admission control (CAC) policy based on a pre-reservation (PR) area as well as we employ the concept of adaptive reserved channel to accomplish quality of service (QoS) requirements for handover traffic requests. A teletraffic model based on queuing theory and Markov chains will allow us to evaluate and quantify QoS metrics performance of the proposed scheme. The numerical results reveal that the benefits of femtocell technology integration with the current macrocellular mobile networks, especially in reducing the traffic loads of macrocell
in terms of minimizing blocking probability.
