Quality of Service (QoS) guaranteed for multimedia services in next generation wireless/mobile cellular networks poses great challenges due to the scarce radio bandwidth. Therefore, the demand for effective and careful resource allocation is immensely needed. In this paper, we combine Call Admission Control (CAC) and Adaptive Resource Allocation (ARA) algorithm into a novel framework, which we call Connection-Level Resource Controller (CLRC) for provisioning connection-level QoS in Multimedia wireless/mobile cellular networks. Simulation results show that the framework is able to reduce Handoff Connection Dropping Probability (HCDP) for active users of real time services to zero level. Thus, it satisfies mobile users' needs resulting in a stable performance levels during heavy load periods. Furthermore, the framework provides a low New Connection Blocking Probability (NCBP), which is translated into high resource utilization. This is a highly desirable property from the service provider point of view.
