In this paper, we propose a combined fair packet scheduling policy and an adaptive connection admission control algorithm, to meet the rapidly increasing demand for providing multimedia services with diversified quality requirements. The new scheduling policy is based on an enhanced weighted fair queuing algorithm, while taking into account the spatial variation of the system characterizing both the user mobility and the signal propagation impairments due to the surrounding effects. The new adaptive QoS oriented CAC function, based on service class differentiation, decides whether the connection request is to be admitted into the system, on the basis of the generated interference level and the waiting time before access. The results indicate that significantly increased traffic performance can be achieved in comparison with other conventional investigated radio resource allocation policies.
