The concept of Logical Service Provision Number (LSPN) is proposed to evaluate the service provision capacity in multicast and unicast integrated multiclass service cellular networks. The tradeoff between call blocking probability and LSPN is investigated and an objective function of maximizing LSPN is proposed. To solve the optimal problem, the system is modeled as a 2K-dimensional Markov process...
In this article, we investigate 4G network architecture and consider two underlying layers: PHY and MAC. We compare two models of wireless access network: pure all-IP and subnet based networks. The pure all-IP model is simple and cost-efficient but causes implementation issues of mobility management and resource coordination. In contrast, the subnet based network enables layer 2 and layer 3 handoffs...
