In this paper, we have proposed two models, shared hybrid access (SHA) and restricted hybrid access (RHA), for the femtocell implementation in the next generation wireless cellular networks.The models proposed are based on the two dimensional Markov chain process.The Third Generation Partnership Project (3GPP) has described two kinds of users in the femtocell application; open users and the closed subscriber group (CSG) users referring to open access and closed access respectively.In this work, for the better explanation of the proposed models, we divide the open users and CSG users in two groups; the non subscriber group (NSG) and the subscriber group (SG) respectively.Both proposed models include the blocking probability analysis for SG and NSG user channels.For the validation of the proposed models, the simulation results of the derived blocking probabilities, for SG and NSG, are provided.We have also provided guidelines for the implementation of the proposed models, based on our simulation results, for improving the quality of service (QoS), at the end of this paper.
