A novel CAC-based network pricing scheme for wireless access networks

In this paper, we proposed a dynamic network pricing scheme, which considers both Call Admission Control (CAC) and Network Congestion Control (NCC), denoted as Contract Binded CAC {CBCAC). CAC calculates the optimal arrival rates and limits the admitted calls at every time. When the network is underlized, all the users are charged for service consumption normally. But if it is congested, they are charged for NCC in addition, and then make a decision for congestion control. The numerical simulation results show that by dynamically computing these prices, our scheme can strike the right balance between the utilization of WANs resources and the blocking probabilities.
