dc.description.abstractUsing intelligent techniques to perform radio resource management is an effective method. This paper proposes neural fuzzy control for radio resource management in hierarchical cellular systems supporting multimedia services. A neural fuzzy resource manager (NFRM) is designed, which mainly contains a neural fuzzy channel allocation processor (NFCAP), and NFCAP is in a two-layer architecture: a fuzzy cell selector (FCS) in the first layer and a neural fuzzy call-admission and rate controller (NFCRC) in the second layer. The FCS chooses not only the handoff failure. probabilities and the resource availabilities in both microcell and macrocell but also the mobility of user as input linguistic variables. The NFCRC takes the handoff failure probability and the resource availability of the selected cell as input variables to perform call admission control and rate control for the call. Simulation results show that NFRM can always gruarantee the quality of service (QoS) requirement of handoff failure probability for all traffic loads. Also, NFRM improves the system. utilization by 31.1% while increasing the handoff rate by 2% over the overflow channel allocation (OCA) scheme [3]; it enhances the system utilization by 6.3% and 1.4%, and still reduces the handoff rate by 14.9% and 6.8%, as compared to the combined channel allocation (CCA) scheme [201, [21] and fuzzy channel allocation control (FCAC) scheme [9], respectively, under a predefined QoS constraint.en_US
