The Next Generation Wireless Networks (NGWN) are expected to offer abundant services to its users. Guaranteeing the agreed upon Quality of Service (QoS), while trying to maximize the revenue of the network operators by having more number of users in the system is a challenging problem. Call Admission Control (CAC) directly controls the number of users in the system and hence utmost care must be taken in the design of an effective CAC framework. This paper proposes a channel reservation model for CAC in NGWN based on the users' QoS needs and the simulation results for call blocking probability of different user classes are presented.
