摘要: In this paper, a fuzzy logic controller (FLC) is proposed to tune several inter-system handover (IS-HO) parameters in heterogeneous scenario with changing traffic distribution. Performance assessment carried out by implementing FLC and IS-HO algorithms dynamic network simulator including GSM UMTS radio access technologies. Preliminary results show that, although the able modify re-distribute between technologies, its speed of response severely limited. A sensitivity analysis then performed quantify effect internal on response. Experiments that tuning ranges steps for controlled have strong impact performance. Results adjusting steps, significant reduction blocked call rates (BCRs) can be obtained some iterations when compared default settings.
