We propose a quality of service (QoS) provisioning framework for multimedia traffic in wireless/mobile networks. We classify the services into three categories: bandwidth guaranteed (BG) service, bandwidth not-guaranteed (BNG) service, and best effort (BE) service. BG service is for non-adaptive multimedia traffic or non-multimedia traffic; BNG service is for adaptive multimedia traffic, whereas BE service is for computer data or multimedia traffic that can be suspended and reactivated. For each of the above three categories, traffic descriptors and QoS parameters are defined and specified. In addition, there are multiple classes for each of the above three categories. For all service categories we present, analytically, an optimal call admission control that guarantees the QoS parameters and traffic descriptors, and maximizes the revenue. Simulation results reveal that the proposed optimal call admission control scheme is very promising
